SYNOPSIS

       sndfile-convert  [-override-sample-rate=rate]  [-endian=little | big | cpu] [-normalize] [encoding] input
                       output

DESCRIPTION

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

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

       wav    WAV (Microsoft)
       aif    AIFF (Apple/SGI)
       au     AU (Sun/NeXT)
       snd    AU (Sun/NeXT)
       raw    RAW (header-less)
       gsm    RAW (header-less)
       vox    RAW (header-less)

       mat    MAT4 (GNU Octave 2.0 / Matlab 4.2)
       mat4   MAT4 (GNU Octave 2.0 / Matlab 4.2)
       mat5   MAT5 (GNU Octave 2.1 / Matlab 5.0)
       pvf    PVF (Portable Voice Format)
       xi     XI (FastTracker 2)
       htk    HTK (HMM Tool Kit)
       sds    SDS (Midi Sample Dump Standard)
       avr    AVR (Audio Visual Research)
       wavex  WAVEX (MS WAVE with WAVEFORMATEX)
       sd2    SD2 (Sound Designer II)
       flac   FLAC (FLAC Lossless Audio Codec)
       caf    CAF (Apple Core Audio File)
       wve    WVE (Psion Series 3)
       prc    WVE (Psion Series 3)
       ogg    OGG (OGG Container format)
       oga    OGG (OGG Container format)
       mpc    MPC (Akai MPC 2k)
       rf64   RF64 (RIFF 64)

   Options
       The following options are recoginzed:

       -override-sample-rate=rate  Make the input use sample rate of rate Hz.
       -endian=little              Make the output file use little endian data.
       -endian=big                 Make the output file use big endian data.
       -endian=cpu                 Make the output file use CPU endianness.
       -normalize                  Normalize the audio data in the output file.

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

       -pcms8       signed 8 bit pcm
       -pcmu8       unsigned 8 bit pcm
       -pcm16       16 bit pcm
       -pcm24       24 bit pcm
       -pcm32       32 bit pcm
       -float32     32 bit floating point
       -ulaw        ULAW
       -alaw        ALAW
       -ima-adpcm   IMA ADPCM (WAV only)
       -ms-adpcm    MS ADPCM (WAV only)
       -gsm610      GSM6.10 (WAV only)
       -dwvw12      12 bit DWVW (AIFF only)
       -dwvw16      16 bit DWVW (AIFF only)
       -dwvw24      24 bit DWVW (AIFF only)
       -vorbis      Vorbis (OGG only)

       If no encoding is specified for the output file, sndfile-convert 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).

EXIT STATUS

       The sndfile-convert utility exits 0 on success, and >0 if an error occurs.
