NAME
speexenc - The reference implementation speex encoder. SYNOPSIS
speexenc [options] input_file output_file DESCRIPTION
Encodes input_file using Speex. It can read the WAV or raw files. input_file can be: filename.wav wav file filename.* Raw PCM file (any extension other than .wav) - stdin output_file can be: filename.spx Speex file - stdout OPTIONS
-n, --narrowband Narrowband (8 kHz) input file -w, --wideband Wideband (16 kHz) input file -u, --ultra-wideband "Ultra-wideband" (32 kHz) input file --quality n Encoding quality (0-10), default 8 --bitrate n Encoding bit-rate (use bit-rate n or lower) --vbr Enable variable bit-rate (VBR) --abr rate Enable average bit-rate (ABR) at rate bps --vad Enable voice activity detection (VAD) --dtx Enable file-based discontinuous transmission (DTX) --comp n Set encoding complexity (0-10), default 3 --nframes n Number of frames per Ogg packet (1-10), default 1 --comment Add the given string as an extra comment. This may be used multiple times --author Author of this track --title Title for this track -h, --help This help -v, --version Version information -V Verbose mode (show bit-rate) Raw input options: --rate n Sampling rate for raw input --stereo Consider raw input as stereo --le Raw input is little-endian --be Raw input is big-endian --8bit Raw input is 8-bit unsigned --16bit Raw input is 16-bit signed Default raw PCM input is 16-bit, little-endian, mono More information is available from the Speex site: http://www.speex.org Please report bugs to the mailing list `speex-dev@xiph.org'.

NAME
oggdec - simple decoder, Ogg Vorbis file to PCM audio file (WAV or RAW). SYNOPSIS
oggdec [ -Qhv ] [ -b bits_per_sample ] [ -e endianness ] [ -R ] [ -s signedness ] [ -o outputfile ] file ... DESCRIPTION
oggdec decodes Ogg Vorbis files into PCM-encoded ("uncompressed") audio files, either WAV 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 appro- priate. If the input file is specified as - , then oggdec will read from stdin, and write to stdout unless an output filename is specified. Like- wise, an output filename of - will cause output to be to stdout. Writing WAV format to stdout is a bad idea. WAV 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 WAV 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. 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 SEE ALSO
