The TwoCC is the audio counterpart to the [[:Category:Video FourCCs|video FourCC]]. It is the audio format identifier used in the [[RIFF]] based multimedia formats by [[Microsoft]] ([[WAV]] and [[AVI]]). The TwoCC is 2 bytes long and stored in little endian format on disk. You can register your TwoCC with Microsoft but it seems that only some companies perform this process.

The TwoCC is the audio counterpart to the video FourCC. It is the audio format identifier used in the RIFF based multimedia formats by Microsoft (WAV and AVI). The TwoCC is 2 bytes long and stored in little endian format on disk. You can register your TwoCC with Microsoft but it seems that only some companies perform this process.

If you need help finding any codec mail me compn@ffmpeg.org
