Top Forums UNIX for Beginners Questions & Answers How to copy only some lines from very big file? Post 302965782 by RudiC on Wednesday 3rd of February 2016 04:15:48 AM
Old 02-03-2016
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
Code:
od -tx1c file
0000000  23  65  6d  70  6e  6f  0a  65  6e  61  6d  65  0a  6a  6f  62
          #   e   m   p   n   o  \n   e   n   a   m   e  \n   j   o   b

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. SEE ALSO
dbin(1), dbfsd(1), dbmixer(1), dbmix(7). AUTHOR
This manual page was written by Daniel Kobras <kobras@debian.org>, for the Debian GNU/Linux system (but may be used by others). It is heavily based on DBMix's README file written by Robert Michael S Dean. August 6, 2002 DBCAT(1)
