This works for sure, but only on jailbroken devices.

On the other hand, facebook can check (at least on IOS) easily if the device is jailbroken and behave differently.

You can also patch binary and inject some code, (probably swizzle AVAudioRecorder methods) for the same effect.

In this case, Facebook can check binary integrity, and change behavior accordingly.

So this is kind a cat and mouse game.
