Aud-X has been engineered as 5.1 channel surround sound CODEC, and is dedicated for the use with MPEG4 (Xvid/Divx) based movies. It is of course also possible to compress 5.1 music with Aud-X.
Aud-X consists of 3 independent parts:

- Aud-X executable file encoder/decoder
- Aud-X DirectShow decoder filter
- Aud-X ACM encoder (for VirtualDubMod and other Audio Compression Manager compatible software).

DirectShow Filter ensures compatibility with the most popular multitedia software players utilizing DirectX (this is around 90% of all). It is responsible for reading Aud-X content present in movies or separate Aud-X soundtracks.

ACM Encoder has been implemented to make movie encoding possible with the use of Audio Compression Manager compatible software (eg. VirtualDubMod)

Executable Encoder/Decoder allows for:

- Independent sound compression (demuxed movie soundtracks, or multichannel recordings),
- Conversion from Aud-X to 6 channel PCM or AC3 format.
