Set AVSession.Mode to "measurement" on iOS

[akreal]

Is your feature request related to a problem? Please describe.

I'd like to set AVSession.Mode to "measurement" on iOS to disable pre-processing like echo cancellation and noise suppression (it seems to remove background music that I'd like to record).

Describe the solution you'd like

Would you accept such code change at all?

What configuration parameter should be used for this?

• new parameter mode with additional possible values for iOS modes;
• existing parameter autoGain: which it's false, set the mode to "measurement" on iOS.

Describe alternatives you've considered

None

Never mind, this actually did not help me. I'm looking for other options to disable the denoising.

So I'm closing this since this is irrelevant.
