Project To PC/Tablet/Phone Audio From Browser Without AGC

IMPORTANT! - Please read this project carefully and only respond if you have direct experience of recording audio to server via web browser.

We are a company that uses audio recordings made via a browser on PC/Tablet/Smartphone and currently the combination of the System and Browsers invokes Noise Reduction and Automatic Gain Control on the recordings. This is not good for our system because we have a separate Audio Processing Module which is more sophisticated and so we want to record Raw Audio (no AGC/Noise Reduction applied).

We are looking for a web engineer who can do some investigation into whether we can record raw audio on the various browsers and systems including:

- Chrome, Firefox, MS Edge & Safari browsers

- MS PC, Mac PC, Android Phone, Apple Phone, Android Tablet, Apple Tablet.

The project will involve creating a URL with a 'Record' button and a 'View Waveform' button.

The idea is to prove (or not) if we can turn off Noise Reduction and AGC on the device when playing a constant 630Hz tone into the device microphone.

Please see the waveform attached that shows the result of AGC/NR on a contsnat tone, you will see the AGC and NR varies the recorded signal wildly!

Please state your experience in this area and how you can assist. We can start on just one browser and one device first.
