Is a standard for storing audio files in Apple operating systems. It was developed in 1988 based on the IFF format and is a lossless format – audio data is stored in an uncompressed form. In essence, AIFF is an analog to WAV for the Apple Macintosh platform.

Sound Blaster VOC files. VOC files are multi-part and contain silence parts, looping, and different sample rates for different chunks. On input, the silence parts are filled out, loops are rejected, and sample data with a new sample rate is rejected. Silence with a different sample rate is generated appropriately. 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.
