How to set record volume using BASS Library - (Solved)

Recommended Posts

Posted (edited)

I'm trying to figure out how to set the record input volume level. I tried using _BASS_ChannelSetVolume($hStream, 50).

That doesn't seem to work on input levels -- just output levels.

Local $hStream = _BASS_RecordStart(44100, 2, 16)

; here is where I want to set the record volume level.

Yes, I saw it.

It controls the Windows Mixer Input Levels.

I can do that, which is no problem. But, I don't want to touch the Windows mixer controls.

I want to set the input level of the BASS Record stream.

Do you just want to adjust the level of a recording without changing the recording device's levels?
If so, you can do that with the BASS_FX_VOLUME effect, like this:

record = BASS_RecordStart(freq, chans, BASS_RECORD_PAUSE, RecordProc, user); // start recording paused
volfx = BASS_ChannelSetFX(recording, BASS_FX_VOLUME, 0); // set a volume effect on it
BASS_FX_VOLUME_PARAM param;
param.fTarget = volume;
param.fTime = 0;
BASS_FXSetParamters(volfx, &param); // apply volume effect settings
BASS_ChannelPlay(record, false); // resume the recording

Please see the BASS_FX_VOLUME_PARAM documentation for details on it.
