Frequently Asked Questions

The Basics

How do I get started?

Read through this FAQ. Consider purchasing a verified hardware platform or one of our dedicated hardware combos (the two computer/Focusrite combos come with the non-activated Windows plugin and VST Host DAW pre-installed) because most other computers won't handle the extremely high CPU load. You can directly download the non-activated plugin for either Windows or Mac by clicking the "Download for..." buttons on this website. If you do buy our Option 1 or Option 2 PRO combo, at least read through "How do I activate..." and "When the dedicated hardware arrives..." in this FAQ. The non-activated plugin runs in trial mode, which simply means there are periodic audio drop-outs. No plugin calibration or live operation required. Tips/tricks and troubleshooting are at the bottom of this FAQ. Click on the social media icons on the main page to see it in action and watch tutorial videos, especially the YouTube playlist. License sales are final, so try it before buying it! Hardware sales adhere to the terms and conditions of each supplier. Cannot ship Option 1 or Option 2 computers to Russia or Ukraine, and cannot ship the Option 1 computer to India. Anybody anywhere can buy a license, and the computers ship globally within a few weeks if there are no supply chain issues at the moment.

What is the latest version of this plugin?

Version 1.1.4, which you can verify in the plugin UI window › Options › About. In VST Host specifically, click the "plugin edit" dial icon next to the blue info icon inside of the plugin instance box to open the UI window. Version history notes are at the bottom of this FAQ.

Will the license work with both Mac and Windows?

Yes, the license is universal.

Are you working on Linux, AAX, or other formats?

Sell your Bitcoin, fund Alpha Labs, then maybe we will.

Can I buy the license using any device, even my phone?

Yes, the license is just a set of numbers that appear on the screen at checkout, and are also emailed to you from Fastspring.

What is a perpetual license?

It lets you keep Version 1.x.x forever without having to periodically revalidate, but you should expect to only get access to free patches and sub-versions, not primary version upgrades.

How do I activate, and what is the license tied to?

The license ties itself to your machine, combining certain hardware identifiers that are most likely to remain permanent over time. Before opening your DAW to activate the plugin, first make sure that you don't have any extra or temporary harddrives or other network devices or cards connected to the computer that are not a permanent part of the machine. Establish an internet connection, then open the DAW and activate the plugin by opening the UI window and clicking on Options and then License Management. In VST Host specifically, click the "plugin edit" dial icon next to the blue info icon inside of the plugin instance box to open the UI window. Enter your credentials and click Activate. If any additional non-permanent hardware elements accidentally get included in the fingerprint for your machine license, this could cause problems for transfers/reactivations in the future if these hardware items come and go. We do not recommend running this plugin on virtual machines or copies of operating systems running on external portable drives, because their identifiers often shift over time. Before updating or reinstalling the OS or sending the computer in for physical repairs, deactivate the current license on the machine so that it can be successfully reactivated again at a later point. The license exists on your machine separately from the plugin/DAW, but can only be managed through the plugin UI. A lost or damaged machine generally means a permanently lost license, so be careful!

How many times can I transfer the license to another machine?

There are no limits on the number of times that you can transfer licenses from machine to machine, even deactivating and reactivating the same machine.

Is there an offline activation/transfer option?

Yes, enter your license credentials, click Activate and follow each of the prompts. For deactivations/transfers, click Deactivate and follow the prompts. You'll need a USB key or other method of transferring text-based files between machines. Do not interrupt or cut short the activation or deactivation process or prematurely close the pop-up windows.

How do I run patches and upgrades?

To run a patch or upgrade, make sure the DAW is not open, download the new version and install it in the same location, then reopen the DAW or restart your machine. You may need to clear the cache and/or rescan for plugins. As of V1.1.2 on our dedicated hardware combos, you will also need to download the latest VST Host folder and select the version associated with your hardware option. Make sure VST Host is not open, delete the current "vsthostx64" folder from your Desktop and replace it with the new one from the downloaded .zip file, then delete the .zip. Open VST Host and, if prompted with a security warning, un-check "Always ask before opening this file" and run the program. Restart your machine to confirm VST Host opens automatically at boot. The plugin must remain on the Desktop for stock performance settings to work, and the file name — including the extension — must remain unchanged.

What exactly am I buying?

The plugin itself is fungible; it will operate on any machine in trial mode with periodic audio drops without an active license. The paid license is tied to the specific machine you choose to run the plugin on, and is sold and emailed to you by Fastspring. The dedicated NUC computers are offered through SNUC. We recommend a GEN4 Focusrite Scarlett audio interface with the driver from our website — Solo for Option 1, 18i16 for Option 2 PRO. GEN2 and older is not recommended.

What happens when I order a dedicated hardware combo?

After correctly filling out the computer request form (including the billing address of your payment method if different from the shipping address), you will receive an automatic confirmation email, and SNUC will contact you within a few business days with a direct payment link including tax and shipping. Note that the Option 1 machine fits into a 1U rackspace. The Option 2 PRO machine short chassis will also fit into a 1U rackspace. After payment, you will receive the computer and any associated Focusrite interfaces that you ordered through Sweetwater or elsewhere, usually within a few weeks if there are no serious supply chain disruptions at the moment.

When the dedicated hardware arrives, what do I do?

First, plug the interface into any computer USB port (except the USB-C port on Option 1, which has been unreliable). Use the USB cables that came with the Focusrite. Make sure the interface is switched on (if applicable), then connect the computer power cable. For GEN4 interfaces, download and install Focusrite Control 2, then download and install the specific driver from our website.

You'll need an HDMI screen and USB keyboard/mouse, and preferably an internet connection to get started. Do not have any extra or temporary harddrives or network devices connected when activating the plugin, as these may get included in the machine fingerprint. In VST Host, click the "plugin edit" dial icon to open the UI window, then choose Options › License Management and activate with your credentials.

Apply any available firmware updates to the interface while connected to the internet. Then go to Settings › System › Sound › More Sound Settings and disable the Focusrite interface on both the Playback and Recording tabs so the computer doesn't send alerts through it during use. Disconnect and disable internet after setup; we recommend disabling Wi-Fi/Bluetooth and disconnecting Ethernet during normal use to reduce CPU load, and because antivirus protection has been turned off to prioritize audio processing.

To power off, briefly press and release the power button (do not hold). If the machine loses power, it will auto-boot on reconnect and recall the last saved performance. Always ensure the interface is connected and on before powering the computer. Best practice is to use a battery backup power supply, as multiple abrupt power losses can corrupt the VST Host folder — a backup copy is in Downloads.

The Details

What is so special about the verified and dedicated hardwares?

There is a very long and complicated list of things that have been done to the machine BIOS, operating system, and various apps and settings to maximize performance for low latency audio plugins. Our dedicated NUC/Focusrite combo options have been optimized for De-Feedback using the Focusrite Scarlett GEN3 and GEN4 interfaces with the specific driver from our website. Even if you already have a nice computer or a popular expensive audio interface, there is no guarantee it will work at extremely low latency. Do not run additional programs, plugins, or change OS/app settings without our approval. In general, we recommend a dedicated hardware unit for De-Feedback, separate from hardware running other programs and apps. To run De-Feedback with other plugins as well, see the verified hardware platform options.

Can I use my own computer hardware?

Sure, give it a try. But since most people don't have hardware capable of running super CPU-intensive plugins reliably for live sound at low latency, we spent about a year testing and verifying the options on our site. We recommend choosing them instead. Another good option is the AU version for Mac on a Silicon (M) series machine, but we can't 100% guarantee performance for Mac in the same way we can on our dedicated hardwares.

How many instances can I run?

As many as your machine CPU will handle at a given buffer size. This also applies to our dedicated hardwares — you can run more instances than advertised if you can tolerate higher latencies.

Can I run other plugins alongside De-Feedback on the dedicated hardware?

De-Feedback requires dedicated hardware in most cases; our NUC/Focusrite combos have only been verified to handle the indicated number of De-Feedback instances with nothing else running. To use other plugins as well, we recommend the verified hardware platforms listed on our website that are designed to be generalized plugin servers.

Does De-Feedback have latency?

No, the plugin runs at zero latency. The only latency to worry about is introduced by your computer and audio I/O method.

How much latency does the hardware introduce?

It depends. The Option 1 combo can do one instance (mono or stereo) at 4.9ms roundtrip at 48kHz on the lowest buffer size of 16 samples with Safe Mode on. The Option 2 PRO can do up to four mono instances at the same latency. The Waves Livebox can run about eight instances with a few other plugins at 3–5ms. The Fourier Audio transform.engine runs six instances with a few other plugins at about 5ms. Yamaha's USB option for DM3/DM7 runs at just under 6ms on the dedicated NUCs. Macs running Dante DVS can do about 6.8ms, or 2.3ms with the Focusrite Rednet TNX.

Can I run the dedicated hardwares at higher sample rates?

The plugin can run at higher sample rates, but we have only confirmed stability on our dedicated NUC/Focusrite hardware at 48kHz. The Waves Livebox and Fourier Audio transform.engine both run fine at higher sample rates — you'll need to increase the buffer size to maintain similar roundtrip latency so the CPU doesn't overload.

Is there a reason to buy the Option 2 PRO if I only need one instance?

Maybe. Connecting a screen or peripherals and opening windows on the Option 1 machine can cause temporary audio glitches, whereas the Option 2 PRO handles this without issue in almost all cases. The PRO machine is also reportedly better under physical stresses like heat and humidity, and is more future-proof for V2+ processing requirements.

Can I buy a small Focusrite interface with the bigger NUC?

Sure, but you'll need to adjust the routing in VST Host. Generally it wouldn't make sense to use a bigger interface with the smaller computer, since it can't handle more than one instance at the lowest buffer anyway — unless you plan to run it at a higher buffer for more instances.

Can I use any Focusrite interface?

Any GEN3 or GEN4 Scarlett product will work fine, but you may need to download the proper control program from Focusrite, then install the driver from our website. Then configure routing in VST Host and save as a performance.

Can I run more instances with a bigger Focusrite interface?

Yes, but you may need to increase the buffer size, which increases latency. For example, two instances on the Option 1 computer at a buffer size of 32. We tested up to eight mono instances on the PRO computer with just under 10ms total latency on larger interfaces.

What happens if I lose or mess up my plugin?

Download the latest version from our website and install it in the same location as before. If you have an active license, it will work fine again. Don't change the file name or extension, and don't move or delete any folders or files the plugin creates. Also don't rename the computer or user account. As of V1.1.3, installing the latest version of the plugin makes previous versions incompatible with your license. If for some reason you want to revert back to an old version, you first have to deactivate using V1.1.3 or later, and reactivate using V1.1.2 or earlier.

What happens if I lose or mess up VST Host?

Download the latest version from our website for your hardware option. Make sure VST Host is not open, delete the current folder from your Desktop and replace it with the new one from the .zip file, then delete the .zip. Open VST Host, un-check "Always ask before opening this file" if prompted, run the program, then restart your machine to confirm it auto-opens at boot.

What happens if I mess up my whole NUC?

Download the image file and load it onto the machine to reset to factory settings. There is a YouTube video that explains how to do this.

Can I have multiple plugin files or versions on my machine at once?

Don't try it. Having multiple copies of this plugin — of the same or different version — on your machine simultaneously could crash it. Delete the current version before downloading or installing any new version on that machine. We designed the licensing system to work with only one plugin file at a time.

What does this plugin actually do?

It helps achieve more gain before feedback from live microphones, largely removes room reverb, and reduces background noise. Think of it as a general vocal cleaner/isolator — operating at zero added latency using extremely advanced AI processing.

Does it work for big and small shows/venues?

Yes, all sizes and kinds. We do notice that if the mic is closer than about 6ft to the loudspeakers, anti-feedback performance can begin to lessen.

Does it work indoors and outdoors?

Yes, both.

Does it prevent all feedback?

No. This version helps to mostly prevent feedback, but if you push the gain high enough you can potentially defeat the algorithm. Future versions will be more aggressive — it's hard to do without changing the sound of the vocals. We're working on it!

Does the plugin change the sound of the vocals?

No, the plugin should not generally change the sound of the vocals under normal conditions. With really high gain settings, this version can occasionally produce short "ringy" or echo-like artifacts that future versions will aim to avoid.

Do I still need to EQ the vocals?

Yes, you'll need to EQ for tone, but this plugin largely reduces the need to burn EQ bands fighting feedback. In extreme situations you can still use a bit of EQ to "ring out" the first few problematic frequencies, just to maximize overall performance.

Is the plugin linear phase?

No, though we tried to keep phase shift to a minimum and it shouldn't be noticeable under normal usage. Note that the small bit of phase shift is not always static — it changes randomly as the AI removes feedback.

Does it change the dynamics?

No, it should not change the dynamic range of the vocals. Under some rare circumstances — considerable background noise, or a singer using a very pure sine-like tone — the vocal level could be slightly reduced momentarily. Future versions will aim to avoid this.

Is it full quality?

Yes, it operates at all normal sample rates from 44.1k to 96k with any bit depth the DAW allows. Audio throughput is full range, and the effective processing range is 100Hz–22,000Hz.

Is it mono or stereo?

It will be mono or stereo depending on how your DAW audio channel is configured. For a mono signal, make sure the channel is configured as mono and that you don't accidentally use one side of a stereo plugin. In VST Host the plugin is permanently stereo — make sure only one side receives audio to treat it as mono. We do not recommend using the stereo version as "dual mono" with independent uncorrelated inputs. The stereo version coordinates phase shifts across channels and is designed for truly stereo inputs (e.g. two nearby microphones picking up the same content). The stereo version uses practically the same CPU as mono.

What can I use it on?

This version is calibrated best for singular human speech and singing vocals, and works "ok" for choirs. It can be destructive to the sound of instruments. Later versions will handle a wider range of sonic inputs.

How close does a person need to be to the mic?

The input can't be too ambient — it needs to be more than 50% direct sound as opposed to ambient, "roomy," or background noise.

Does it work with all kinds of vocal sounds?

No, vocal sound FX or alternative vocalization devices may not always be handled perfectly. Future versions will aim to improve this.

Does it have a threshold?

No, anything from whispering to shouting will work fine.

Does the plugin have any user-defined parameters?

There is a strength level where 0% is unprocessed and 100% is fully processed. We recommend leaving it at 100% for normal use. There is also a mute button for patch troubleshooting.

Are there other plugins like this?

Not that we know of — that's why we made this one. We got tired of waiting for the "big" companies to solve the problem of feedback without destroying the sound through ridiculous EQ dips and annoying volume thresholds/gates. AI was the obvious answer, and this plugin is a good start.

How does it work?

Magic. (Seriously: we trained our boutique AI model with many terabytes of customized audio data, telling it to listen for feedback, room reverb, and background noise, and then eliminate those from the vocal signal in real time with no latency. Easier said than done.)

Will there be more versions?

Yes, we're already working on them, but AI tech is hard and we're only comfortable releasing what has proven stable and reliable. We plan about one new primary version per year, with patches along the way, if we manage to raise the funds necessary to continue R&D.

How much better will future versions be?

It depends. If lots of people buy this first version, we'll have funds to reinvest in better AI training hardware, more staff, and more training data. Progress is highly proportional to the amount of new training data we can compile and the time it takes to train new models.

Can I sell my license to someone else?

Sure, but we only offer free "support" for our product up to two degrees of ownership transfer. You can of course always sell it to whomever whenever, but this means we only officially support you and the next person you sell it to, but nobody after that, at least not for free. We also don't support renters — you are expected to be the support line for anyone you rent to. Note: it is against the Windows IoT Enterprise license agreement to make copies of the OS or disk.

Can I sell my hardware to someone else?

Sure, but check the manufacturer's terms and conditions first.

Do you have dealers or distributorships?

Not at this time, but we do offer discounts on bulk license orders of ten or more.

Do you have educational discounts?

Not at this time.

How can I help this project succeed?

Tell everyone you know about it! Post success stories on social media and tag Alpha Sound, our parent company. Let us know privately how we can improve the plugin, and be honest.

What is Alpha Labs?

Alpha Labs LLC is a software startup company. The plugins Alpha Labs develops were firstly intended for use by our parent company Alpha Sound, but are now available for sale to the public. Enjoy!

Tips & Tricks

Where in the signal chain should I insert De-Feedback?

It sounds its absolute best inserted on a single vocal channel. Some people run the mic into the interface, then out into the mixer. Others insert it on the mixer channel itself. For multiple vocals that aren't talking/singing simultaneously, create a subgroup on your mixer with the plugin inserted, preferably after vocals have been managed by an automixer like Dugan. Be aware that too many vocals simultaneously can trick the plugin — keep minimal discrete vocal signals through any individual instance.

The plugin works best with a raw uncompressed vocal signal, but for most situations a post-EQ/dynamics or post-fader signal is fine. Be careful not to clip the inputs of your interface.

Using Yamaha USB with DM3 or DM7

Download the Yamaha Steinberg USB driver (pre-installed on our recommended NUC hardware options as of Jan 1, 2025) and select the Yamaha ASIO device in the DAW. Go to the ASIO control panel and set the mode to Standard with latency at the lowest setting for Option 2 PRO, or second-lowest for Option 1. On your Yamaha console, select USB as the I/O.

A good arrangement: send channels to a mix (not the stereo bus), send that mix to the stereo bus, but insert the mix through USB to the computer. This lets you run multiple vocal channels through a single instance — just ensure no more than two or three vocalists are talking/singing simultaneously for best performance. Make sure the console is on before the computer so the DAW automatically reconnects after a power cycle.

Can I use mic and/or line level inputs on the recommended options?

Yes. On the Solo using the "1 mono (inputs 1/2 summed, outputs 1/2 mirrored)" performance, you can plug into either the XLR or 1/4" inputs and they'll be summed into the one plugin instance, with the output mirrored on both interface outputs. On the 18i16 using the "4 mono (inputs 1/5, 2/6, 3/7, 4/8 summed)" performance, channels 1–4 are summed with channels 5–8 respectively, each summed pair going into its corresponding plugin instance and out to its corresponding output.

Troubleshooting

VST3 file shows up as an application or won't load

Go to View Hidden Files or uncheck "Hide extensions for known file types" and see if the file extension says Defeedback.vst3.exe, ./Defeedback.vst3, or ._Defeedback.vst3. If so, delete those extra characters and try again. The file should always be exactly Defeedback.vst3 with no other characters or symbols in the name.

Still getting feedback like nothing changed

Make sure you are actually running audio through the plugin and nowhere else. If you click Mute in the plugin UI window, all audio should go away. If not, there's a problem with your patching/routing.

Terrible audio distortions from Focusrite even after updating firmware

Make sure your USB cable is a data transfer cable, not merely a charging cable — preferably the one that came with the Focusrite. Make sure you're using the recommended driver. If you're on your own machine, try increasing the latency (buffer size).

Audio sounds like a robotic tin can

You likely have a parallel patch somewhere — make sure you aren't sending both an unprocessed and a processed version of the signal to the main output. On Focusrite units, make sure the "Direct" button is white, not green. As a test, mute the plugin and make sure all audio goes away; if not, there's a patching/routing problem.

AnyDesk issue / discovering other De-Feedback machines

Click on the hidden icons in the lower right corner of the screen, right-click AnyDesk and close it. Search Settings for "Add or Remove Programs" and uninstall AnyDesk. If desired, redownload and reinstall AnyDesk afterward. (Known AnyDesk addresses: 1 811 905 542 or 1 585 450 973.)
