The mapping is designed so that the position in the +interval is proportional to the volume as a human ear would perceive +it, i.e. the position is the cubic root of the linear sample +multiplication factor. For controls with a small range (24 dB or +less), the mapping is linear in the dB values so that each step has +the same size visually. + +Only for controls without dB information, a linear mapping of the +hardware volume register values is used (this is the same algorithm as +used in the old \fBalsamixer\fP). + .SH SEE ALSO \fB amixer(1), |
