examples
Decode a file enabler.ogg to enabler.wav
as little-endian unsigned 16-bit (default options):
oggdec enabler.ogg
Decode a file enabler.ogg to enabler.raw as
headerless little-endian unsigned 16-bit:
oggdec --raw=1 enabler.ogg
Decode enabler.ogg to enabler.crazymonkey as
unsigned 8-bit:
oggdec -b 8 -s 0 -o enabler.crazymonkey enabler.ogg
Decode enabler.ogg to enabler.raw as big-endian
signed 16-bit (any of the following):
oggdec -R -e 1 -b 16 enabler.ogg
oggdec -R -e 1 -b 16 -o enabler.raw - < enabler.ogg
oggdec -R -e 1 -b 16 - < enabler.ogg > enabler.raw
Mass decoding (foo.ogg to foo.wav, bar.ogg to bar.wav, quux.ogg
to quux.wav, etc.):
oggdec *.ogg
source
oggdec --quiet -o - "$1" | lame
--silent -
source
for X in *.ogg ; do
Y=${X%.*}
oggdec $Y.ogg ; lame
$Y.wav $Y.mp3
done
description
oggdec
decodes Ogg Vorbis files into PCM-encoded
("uncompressed") audio files, either Wave or RAW
format.
For each input
file, oggdec writes to a filename based on the input
filename, but with the extension changed to ".wav"
or ".raw" as appropriate.
If the input
file is specified as - , then oggdec will read
from stdin, and write to stdout unless an output filename is
specified. Likewise, an output filename of - will
cause output to be to stdout.
Writing Wave
format to stdout is a bad idea. Wave requires a seekable
medium for the header to be rewritten after all the data is
written out; stdout is not seekable.
options
-Q, --quiet
Suppresses program output.
-h, --help
Print help message.
-V, --version
Display version
information.
-b n, --bits=n
Bits per sample. Valid values
are 8 or 16.
-e n, --endian=n
Set endianness for 16-bit
output. 0 (default) is little-endian (Intel byte order). 1
is big-endian (sane byte order).
-R, --raw
Output in raw format. If not
specified, writes Wave file (RIFF headers).
-s n, --sign=n
Set signedness for output. 0
for unsigned, 1 (default) for signed.
-o filename,
--output=filename
Write output to specified
filename. This option is only valid if one input [file] is
specified, or if raw mode is used.
