As no samples are available, I have to guess there is something special with the input file. Did you test the suggestions with a simplified (abbreviated) dummy input file, possibly created copying a section of the original? Please post a (small but representative) hexdump of the input. Should look like

I have an awk script that would search the input file for line that starts with a number 3 and copies into a new text file.

Here is what I have so far:... (1 Reply)

dbcat
DBCAT(1) General Commands Manual DBCAT(1)NAME
dbcat - Send audio data to DB Fourier Synthesis daemon
SYNOPSIS
dbcat [options]
DESCRIPTION
The dbcat tool provides a simple means to feed dbfsd with audio data. Both programs are part of the DBMix project, a digital audio mixing
system. dbcat takes input data from its standard input only, and is therefore usually used in a pipe with some other sound generating pro-
gram.
OPTIONS -8 Input data comprises of PCM-coded 8bit unsigned samples. (Default: 16bit signed samples.)
-c n Connect to channel n of dbfsd. (Default: first channel available.)
-d Print out debug messages to console. (Default: debugging disabled.)
-h Print summary of available options.
-m Input data is a mono stream. (Default: interleaved stereo stream.)
-r rate
Input data is sampled at rate Hertz. (Default: 44100Hz.)
-v Print version information. (Default: no version information.)
-S Produce an endless stream of blank audio data (silence). Any input data is dropped. This mode provides a dummy source useful for
testing and debugging. (Default: pass on input data.)
EXAMPLES
mpg321 -s test.mp3 | dbcat
Sends a 16bit/44.1kHz stereo audio stream decoded from test.mp3 off to dbfsd.
