• Following command to rip CDs:
    ogg: rip -b 192 -c -e -f "T-S" -T
    mp3: rip -q 3 -c -e -f "T-S" -T -L -v
  • Following command to rip CDs with jack and generate an ogg file:
    cd /home/shared/music/justripped; jack --create-dirs --query-now --rename --bitrate 192 --quality 6 --rename-fmt 'l_t' --rename-fmt-va 'l_t'--remove-files; eject; sleep 60; rm jack*;
  • If MusicMagixMixer does not work try:
    Insert into mmm.ini the following
    Or just to switch off the network.
  • If you have more than 1 sound soundcard in your system you can choose the right one in mplayer by:
    Have a look at the file /proc/asound/pcm
    In that file have a look at the numbers at the beginning like 00-01
    In mplayer give the option "-ao alsa:device=hw=0.1"
  • To save a radio stream using mplayer run "mplayer -dumpstream "
  • The configuration files of Amarok are located under:
    - ~/.kde/share/apps/amarok (stored in a SQLite database)
    - ~/.kde/share/config/amarokrc
  • Use Pulseaudio to stream audio from multiple clients to a central server.
  • Ardour: a multi-track recorder.
  • ffmpeg: to dynamically normalize audio:
    ffmpeg -i input.mp4 -vcodec h264 -af "dynaudnorm" -acodec mp3 output-normalized.mp4
  • To avoid that Amarok displays a message saying something like Xine was unable to initialize any audio drivers, modify in the configuration (ev. directly edit the file ~/.kde/share/apps/amarok/xine-config) the parameters as follows:
    (have a look at cat /proc/asound/pcm for the device numbers)
  • To redirect the output from one soundcard into another (here from /dev/dsp to /dev/dsp1):
    sox -c 2 -s -2 -r 44100 -t ossdsp /dev/dsp1 -t ossdsp -2 -r 44100 /dev/dsp
    To have all alsa applications send audio to Jack write the following "$HOME/.asoundrc" (and/or "/etc/asound.conf"):
       type plug
          pcm "myjack"
       type plug
       slave { pcm "jack" }
       type jack
          0 alsa_pcm:playback_1
          1 alsa_pcm:playback_2
          0 alsa_pcm:capture_1
          1 alsa_pcm:capture_2
