MP3

This will take an mp3 stream and turn it into a wav file.

mpg123 -b 10000 -s http://some.stream | sox -t raw -r 44100 \
-s -w -c 2 - stream.wav

mp3 files to wav

This will convert your MP3 file back to a *.wav file

mpg123 -w new_wav.wav mp3_file.mp3

Ogg Vorbis

To rip something directly to ogg, your version of sox should have ogg vorbis support. Recent versions do.

cdparanoia -qer 19 -| sox -t raw -r 44100 -s -w -c 2 - Artist_Song.ogg

Notes:

• drop the 'e' option if you don't want to see the output
• 'r' is little-endian - most sound cards
• 'q' is quiet

encode wav to ogg

If you've ripped the file with cdparanoia, for example.

oggenc -a "artist" -t "song_title" -l "Album Name" -b 192 \
wav_to_encode.wav -n "%a_%t.ogg"

ogg stream back to ogg

Use sox to convert a remote ogg stream back to a local ogg file.

ogg123 http://some.ogg.site/stream.ogg -d wav -f - | \
sox -t wav -r 44100 -s -w -c 2 - stream.ogg

ogg stream to wav

Similar to above, this converts the stream to *.wav, which you will be able to edit.

ogg123 -d oss -d wav -f stream.wav http://some.stream.site/stream.ogg

ogg2cdda If you have some *.ogg files that you want to put on a CD in CD audio format (to be played in a conventional CD player), the following script will speed up the process.

#!/bin/sh

for oggfile in *.ogg ; do
   cddafile="`basename $oggfile .oggcdda"

oggdec -b 16 -e 1 -o $cddafile done

You can then burn a CD:

cdrecord -v dev=/dev/sga speed=8 -audio -dao pregap=0 -eject *.cdda

note: for big files, use -pad before -audio

General

You can change the sound of the beep from your PC's speaker by changing these numbers. First is length, followed by pitch and tone.
