a python script for making seamless loops in samples by cross fading

It uses sox and ecasound for processing and should work with wav, aiff and flac (maybe more).

planned (?): libsndfile support.

convert a Hydrogen drumkit into a SF2 soundfont

conversion examples with mplayer / mencoder

  mplayer -ao pcm:file=$F.wav $F
  lame -h $F.wav $F.mp3;

  # flac_to_mp3
  for f in *.mp3; do lame -v "$f"; done

Using MEncoder to create DVD-compliant files

convert DV files to DVD compliant

convert sound files with libsndfile



conversion examples with sox

convert a .wav file to raw PCM - here 8bit (-b 8) signed integer (-e signed), stereo (-c 2):

sox INFILE.wav -t raw -r 48k -e signed -b  8 -c 2 OUTFILE.raw

convert raw CD digital audio (16-bit, signed-integer) to floating point wav:

sox input.cdda -e float output1.wav

generate (-n = NULL input) a .wav file with a 3 second sine-sweep:

sox -n OUTFILE.wav synth 3 sine 300-3300 gain -5

The format-options must be given before the filename for which they're intended. If unspecified they are read from the file header (if possible):


sox [global-options] [format-options] infile1 \ 
    [[format-options] infile2] ... \
    [format-options] outfile \
    [effect [effect-options]] ...

Common encoding-types for -e: signed, unsigned, float. see man sox for a complete reference.

conversion examples with ecasound



move regions, markers, temi in an Ardour session

A script to slide every regions, markers, tempi, meters, automations, and so on in an Ardour session.

“Actually, it's not really a solution, as one can move only ALL REGIONS,…”

spaces to underscores

#! /bin/bash
echo "This command changes all spaces in file names into underscores"
echo "  Type ENTER to continue or ^C to quit"
read dummy
for f in *; do
 oldname=`echo $f |sed 's/ /~/g'`
 newname=`echo $f |sed 's/ /_/g'`
 if [ $oldname != $newname ]
   echo mv $f $newname
   mv "$f" $newname

use a proper python shell

(by Torben Hohn, 28. September 2010 01:16 )

ipython is there for quite some time.

and i recently discovered bpython

this is where the fun starts

also help() works nicely on instances.

doctests also pretty much kick ass.
