Note that the volume may also be scaled by the system volume if configured (see SWI PlayIt_Config 0). Amplification may be useful (volumes > 127) for playing low amplitude (ie quiet) samples or playing louder than the system volume currently allows. Distortion (due to clipping) will most likely occur if the amplification is too high.

By default, PlayIt's volume is independent of the system volume - see SWI PlayIt_Config 0.

Some useful reference volumes are:

R0 | linear | dB

0 | ÷256 | -24
31 | ÷64 | -18
63 | ÷16 | -12
95 | ÷4 | -6
127 | x1 | +0
159 | x4 | +6
191 | x16 | +12
