1. There isn’t any way to control the volume when recording a sound, there is no processing involved just recording.

2. You can attach a DSP to either the Channel or ChannelGroup, not the sound itself.  
[https://fmod.com/resources/documentation-api?page=content/generated/FMOD\_Channel\_AddDSP.html#/](https://fmod.com/resources/documentation-api?page=content/generated/FMOD_Channel_AddDSP.html#/)

3. You could do that although you would have to treat it as a ring buffer.  
A better, lower latency, way of doing this would be to use a DSP and read from the incoming buffer into the DSP callback, then use [System::playDSP](https://fmod.com/resources/documentation-api?page=content/generated/FMOD_System_PlayDSP.html#/).  
We have an example of a custom DSP in our LowLevel API examples.
