BASS_ATTRIB_MUSIC_AMPLIFY attribute


The amplification level of a MOD music.

BASS_ChannelSetAttribute(
    HMUSIC handle,
    BASS_ATTRIB_MUSIC_AMPLIFY,
    float amp
);

Parameters

handleThe MOD music handle.
ampAmplification level... 0 (min) to 100 (max). This will be rounded down to a whole number.

Remarks

As the amplification level get's higher, the sample data's range increases, and therefore, the resolution increases. But if the level is set too high, then clipping can occur, which can result in distortion of the sound.

You can check the current level of a MOD music at any time by using BASS_ChannelGetLevel. By doing so, you can decide if a MOD music's amplification level needs adjusting.

The default amplification level is 50.

During playback, the effect of changes to this attribute are not heard instantaneously, due to buffering. To reduce the delay, use the BASS_CONFIG_BUFFER config option to reduce the buffer length.
