• 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
  host=music2.predixis.com
  proxyport=80
  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:
  audio.device.alsa_default_device:plughw:0,0
  audio.device.alsa_front_device:plughw:0,0
  (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"):
  pcm.!default
  {
     type plug
     slave
     {
        pcm "myjack"
     }
  }
  pcm.jackplug
  {
     type plug
     slave { pcm "jack" }
  }
  pcm.myjack
  {
     type jack
     playback_ports
     {
        0 alsa_pcm:playback_1
        1 alsa_pcm:playback_2
     }
     capture_ports
     {
        0 alsa_pcm:capture_1
        1 alsa_pcm:capture_2
     }
  }
