This appendix describes the audio data and file formats supported in Core Audio in OS X v10.5.

Download Pcm Player For Os X - real advice. Tool to convert files containing stereo or mono, as linear PCM encoded sound data, into AIFF format. The TLV320AIC1106 PCM codec is designed to perform transmit encoding analog-to-digital (A/D) conversion, receive decoding digital-to-analog (D/A) conversion, and transmit and receive filtering for voice-band communications systems. The TLV320AIC1106 device operates in either the 13-bit linear or 8-bit companded (µ-law) mode.

Each audio file type lists the data formats supported for that type. That is, a converter exists to convert data from the particular file format to any of the listed data formats. Some data formats (such as AC3) cannot be converted to a linear PCM format and therefore cannot be handled by standard audio units.

A Core Audio Format (CAF) file can contain audio data of any format. Any application that supports the CAF file format can write audio data to the file or extract the data it contains. However, the ability to encode or decode the audio data contained within it is dependent on the audio codecs available on the system.

Core Audio includes a number of audio codecs that translate audio data to and from Linear PCM. Codecs for the following audio data type are available in OS X v10.4. Audio applications may install additional encoders and decoders.
