[New Feature] Edit the capture PCM format(integer or float, bitwise, etc)

[mkckr0]

Describe the new feature you'd like
I propose to add "edit the capture PCM format(integer or float, bitwise, etc)"

Describe the reason why you want to add the feature
I need this feature because 32-bit float PCM format may need conversion between floating-point and integer. It may slow down the performance and increase the latency. Most of audio devices only support integer PCM format.

Describe how to implement the feature if you can
