Man1 - sndfile-convert.1

converts sound files from one audio format to another. The output file is overwritten it it already exists.

The format of the output file is determined by the filename extension. The following file formats are currently recognized:

WAV (Microsoft)

AIFF (Apple/SGI)

AU (Sun/NeXT)

RAW (header-less)

PAF (Ensoniq PARIS, big-endian)

PAF (Ensoniq PARIS, little-endian)

IFF (Amiga IFF/SVX8/SV16)

SPHERE (NIST SPeech HEader Resources)

VOC (Creative Labs)

SF (Berkeley/IRCAM/CARL)

W64 (SoundFoundry WAVE 64)

MAT4 (GNU Octave 2.0 / Matlab 4.2)

MAT5 (GNU Octave 2.1 / Matlab 5.0)

PVF (Portable Voice Format)

XI (FastTracker 2)

HTK (HMM Tool Kit)

SDS (Midi Sample Dump Standard)

AVR (Audio Visual Research)

WAVEX (MS WAVE with WAVEFORMATEX)

SD2 (Sound Designer II)

FLAC (FLAC Lossless Audio Codec)

CAF (Apple Core Audio File)

WVE (Psion Series 3)

OGG (OGG Container format)

MPC (Akai MPC 2k)

RF64 (RIFF 64)

The following options are recoginzed:

Make the input use sample rate of

Hz.

Make the output file use little endian data.

Make the output file use big endian data.

Make the output file use CPU endianness.

Normalize the audio data in the output file.

The optional

parameter allows setting of the data encoding for the output file. The following encodings are currently supported:

signed 8 bit pcm

unsigned 8 bit pcm

16 bit pcm

24 bit pcm

32 bit pcm

32 bit floating point

ULAW

ALAW

IMA ADPCM (WAV only)

MS ADPCM (WAV only)

GSM6.10 (WAV only)

12 bit DWVW (AIFF only)

16 bit DWVW (AIFF only)

24 bit DWVW (AIFF only)

Vorbis (OGG only)

If no encoding is specified for the output file,

will try to use the encoding of the input file. This will not always work as most container formats (e.g. WAV, AIFF etc) only support a small subset of encodings (e.g. 16 bit PCM, a-law, Vorbis etc).
