Details

Feedback Killer AI 4CH removes feedback (howl) from live sound automatically with AI, on an Android phone or an iPhone. Plug a USB audio interface into the device (or use the built-in mic) and press one AI button per channel; nothing to set up.

One AI button per channel: the app listens for feedback and places notches by itself, in real time (the same AI as the Feedback Killer AI plug-in)
4 channels in and out, following your interface; ROUTING page
IN / OUT meters and an RTA on every channel, global BYPASS, save and load your setup
If the audio device drops out or the buffer struggles, audio passes straight through instead of going silent (fail-safe)
A phone app: tablets and iPads use the 8CH / 16CH app

Free for 7 days with every feature. Then buy the full version on tsoundman.com: the key unlocks one device, an Android phone or an iPhone. After the trial, without the full version, audio passes through unprocessed.

On Android: download the .apk on the device and open it (if asked, allow "install unknown apps" for the browser or file app you use), then enter the key on the app's SETTINGS page.

On the iPhone: install Feedback Killer AI 4CH from the App Store (free download), then go to Settings > FULL VERSION > Sign in and sign in with the e-mail and password of the tsoundman.com account you bought it with. No key to type.

Moving to a new device: sign out on the old iPhone, or release the device in My library, then use the new one.

Version history

1.0.5 - VOICE ONLY no longer loses the first syllable of a phrase when a band or crowd is in the mic: the mic opens at once. A quiet room still closes fully between phrases.
1.0.4 - New VOICE ONLY switch: the channel's mic closes by itself while nobody sings or speaks and opens again the moment a voice comes in / AUTO NOISE runs a new AI (AI 2) that tells singing and speech from music and noise bleeding into the mic far more accurately / Treble howls (2 kHz and up) are caught sooner, while still quiet, even when the voice is louder. No extra cuts on singing or music / Lighter on the CPU: the work is spread over every core, with bit-identical sound / Move devices yourself: Deactivate in SETTINGS gives the key back so you can activate the new device at once / Help improve the AI (new, only if you say yes, asked once): each AI cut sends that mic's sound from 45 s before to 25 s after with the technical settings (nothing personal, at most 20 a day; off any time in SETTINGS; details at tsoundman.com/privacy)
