output [channel] compressor

Dynamic range compression (DRC) or simply compression is an electronic effect unit that reduces the volume of loud sounds or amplifies quiet sounds by narrowing or "compressing" an audio signal's dynamic range

The command allows any number of options to be specified. Unspecified arguments remain at the last set value.

When using the import subcommand, any imported crossover group is automatically unbypassed.

Examples

Protect subwoofers from applying a wrong BEQ profile or leaving a profile enabled as recommended in the Bass EQ thread

minidsp output 0 compressor -b off -k 50 -a 15 -r 30 -t 0

Limit the dynamic range of a tactile transducer or bass shaker. This would allow them to turn on more often but not be driven too hard.

minidsp output 3 gain -- 12
minidsp output 3 compressor -b off -k 50 -a 15 -r 30 -t -- -36

Usage

$ minidsp output 0 compressor --help
