; Specify a file into which sidd will write messages.logfile ./sidd.log; The input device and mixerdevice /dev/dspmixer /dev/mixer; Specify the mode of operation - stereo or mono. In stereo mode,; sidd will run two independent monitors, each with its own output file.mode stereo; The requested sample rate. The software will use the closest; setting available from the soundcard.rate 48000; Sample size, 8 or 16 bits. 16 bits is strongly recommended, 8 bit is; provided in case your soundcard or driver doesn't do 16.bits 16; Number of frequency bins to use. The FFT size is 2*bins and the program; will issue an output record every (2*bins)/rate seconds.bins 2048; Line input gains, left and right. If using mono, set them both the same.; Range is 0 to 100. The logfile will report the actual values set, which; may differ a little.gain line 77 100; Overall input gains, comments as above.gain overall 86 100; Overall record level, comments as above.;; gain record 100 100; Specify a directory to contain daily data files. Use '.' for the; current directory. Output files will be datadir/yymmdd.dat when running; in mono, otherwise datadir/yymmdd.left.dat and datadir/yymmdd.right.datdatadir .; Enable real time scheduling of sidd. Recommended so that soundcard buffers; are read promptly, which means minimum latency before each fft buffer is; timestamped. You have to be running as root for this to work.sched high; Specify the email address of whoever is to get any bad news.; mail someone@someplace; The loss-of-signal warning threshold and time delay. If the input; signal peak level (0-1.0) falls below the given threshold for more than; the delay time, a warning will be issued. The threshold applies to both; left and right in stereo mode, on the assumption that you've set the gains; so that the signal levels are about the same anyway.los 0.06 5; Specify a file into which spectrum data will regularly be written.; This file is overwritten with a fresh spectrum roughly every; 100 * 2 * bins/rate seconds. The spectrum file contains three space; separated columns: bin centre frequency (Hz) and the average power; in the bin (relative), for the left and right channels. In mono mode,; there are just two columnsspectrum /tmp/sidspec 100; Specify the channels to monitor.
