minidsp output n peq and
minidsp input n peq commands both support importing from a REW-formatted file. If there are less
filters on the device, the remaining PEQs will be cleared.
Here is how you would import a series of biquad filter to output channel 3:
$ minidsp output 3 peq all import filename.txt PEQ 0: Applied imported filter: biquad1 PEQ 1: Applied imported filter: biquad2 PEQ 2: Applied imported filter: biquad3 ...
If you were to select a single peq, only one filter would have been imported:
$ minidsp output 3 peq 1 import filename.txt PEQ 0: Applied imported filter: biquad1 Warning: Some filters were not imported because they didn't fit (try using `all`)
$ minidsp output 0 peq --help minidsp-output-peq Control the parametric equalizer USAGE: minidsp output <OUTPUT_INDEX> peq <INDEX> <SUBCOMMAND> ARGS: <INDEX> Parametric EQ index (all | <id>) (0 to 9 inclusively) OPTIONS: -h, --help Print help information SUBCOMMANDS: bypass Sets the bypass toggle clear Sets all coefficients back to their default values and un-bypass them help Print this message or the help of the given subcommand(s) import Imports the coefficients from the given file set Set coefficients
