Feedback Eliminator

An automatic electronic device that senses the onset of feedback, and cancels it before it gets out of hand. This is achieved by using a specialized equalizer with multiple, very narrow filter bands, positioned between the audio source and the speakers. The unit "searches" for the beginnings of feedback, analyzes the problem frequency and cuts that band.

Feedback

In acoustics, the undesirable leakage of audio from loudspeakers, back into the same microphone which is being used for originally capturing the audio. If too much feedback occurs, the system can go into self-oscillation, causing unpleasant howling or squealing.

Live immersive choir with feedback-exclusion

I am working on experimental scenario which is proving to be an audio challenge. I aI'm to gather a group of between 5 and 30 people to drone and sing chorally together. This should then be amplified by mics situated within the group, whilst a large soundsystem surrounding the group amplifies the drone (with and without effects). The aI'm is to create immensely powerful immersion.

Avenson STO-2 feedback

Has anyone had any experience with these as drum overheads? I have heard a few sample recordings and they seem to be very accurate and rather encompassing. From the samples I have heard they seem to make you feel like you are right in there behind the kit. I would love to hear what anybody has to say about them.
