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) paf PAF (Ensoniq PARIS, big-endian) fap PAF (Ensoniq PARIS, little-endian) svx IFF (Amiga IFF/SVX8/SV16) nist SPHERE (NIST SPeech HEader Resources) sph SPHERE (NIST SPeech HEader Resources) voc VOC (Creative Labs) ircam SF (Berkeley/IRCAM/CARL) sf SF (Berkeley/IRCAM/CARL) w64 W64 (SoundFoundry WAVE 64) 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).

InstallationHelp
Objects have a set of files that comprise that object, as seen in the Files tab. When an object is built, they have a set of files that are the result of that build. In each case, these sets of files are the ones that are accessible within a virtual machine when running the object.

This section describes how those files are accessible and visible to that machine. When a virtual machine is created, the data is always accessible read-only within a particular mounted directory. However, applications may expect to be located at particular directories. This section allows one to place files in different directories when the virtual machine is launched.

There are two types of access. One is a link where the file is not copied from its original location. Instead, it creates what is called a symbolic link which is a "shortcut" that acts like a normal file but allows the actual data to be in a different directory. The other type is a traditional copy which copies the data explicitly to the provided destination. This takes more time, but the copy can be modified, unlike the read-only link type.
