BASS_ATTRIB_VOL attribute

The volume level of a channel. 

BASS_ChannelSetAttribute(
    DWORD handle,
    BASS_ATTRIB_VOL,
    float volume
);

Parameters

handleThe channel handle.
volumeThe volume level... 0 (silent) to 1.0 (full). This can go above 1.0 on decoding channels.

Remarks

This attribute applies to playback of the channel, and does not affect the channel's sample data, so has no real effect on decoding channels. It is still adjustable then though, so that it can be used by the BASSmix add-on and anything else that wants to use it.

When using BASS_ChannelSlideAttribute to slide this attribute, a negative volume value can be used to fade-out and then stop the channel.
