Sound

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.
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
   }
}
