for details on command line parameters see --help
First argument is the audio file to be measured.
Other parameters can follow in free order.
This is free software, and you are welcome to redistribute it
under the GPL v3 licence.
Program will use 1 + 13 slave threads.
Order of parameters after audio file is free.
Possible parameters are:
--convpoints <integer number> Use convolution with n points interpolation instead of polynomial filter.
Default is polynomial filter.
--numcpus <integer number> Number of slave threads to speed up operation.
--timing For benchmarking speed.
--chconfcal <dB correction> <dB correction> <etc. so many times as channels>
--leqnw output leq with no weighting
--logleqm10 (will also print Allen metric as output)
--lkfs Switch LKFS ITU 1770-4 on.
--dolbydi Switch Dolby Dialogue Intelligence on
--chgateconf <0|1|2>, 0 = no gate, 1 = level gate (in dB) and 2 = dialogue gate
--agsthreshold <speech %> For Leq(M,DI) and LKFS(DI) default 33%.
--levelgate <Leq(M)> This will force level gating and deactivate speech gating
--threshold <Leq(M)> Threshold used for Allen metric (default 80)
--longperiod <minutes> Long period for leqm10 (default 10)
--logleqm Log Leq(M) from start every buffersize ms.
--buffersize <milliseconds> Size of Buffer in milliseconds.
--truepeak Show true peak value
--oversampling <n> Default: 4 times
--printdiinfo Show detailed speech intelligence information
Using:
gnuplot -e "plot \"logfile.txt\" u 1:2; pause -1"
it is possible to directly plot the logged data
Output in text format
