sph
SPeech HEader Resources

SPHERE (SPeech HEader Resources) is a file format defined by NIST (National Institute of Standards and Technology) and is used with speech audio. SoX can read these files when they contain μ-law and PCM data. It will ignore any header information that says the data is compressed using shorten compression and will treat the data as either μ-law or PCM. This will allow SoX and the command line shorten program to be run together using pipes to encompasses the data and then pass the result to SoX for processing.

tta
True Audio

TTA is a simple and stable lossless audio data format for real-time compressing of digital music. Free and fully-functional for any use. It has a very simple structure. The TTA file header contains a unique format identifier, which is followed by meta-data block. Meta-data block contains minimal information which is needed for restoring the original stream (including number of channels, count of bits per sample, sample rate and overall number of samples in file, etc.) and ended by a 32-bit control sum. Following that header, we write one or more audio frames. Each frame is ended by a 32-bit control sum; a decoder may start decoding from any frame in the stream. The compressed samples of channels in a frame are located sequentially, as in a simple PCM data format.

txw

On output, silence is not detected, nor are impossible sample rates. SoX supports reading (but not writing) VOC files with multiple blocks, and files containing μ-law, A-law, and 2/3/4-bit ADPCM samples.
