Aud-X 5.1 Surround Codec

Freeware – Aud-X – Windows

Aud-X is the name of a completely new surround sound encoder and decoder created by group of audio enthusiasts and professionals joined with love to the Cinema.

For a long time people converted DVDs to Divx/Xvid with mp3 stereo sound. We have all felt that part of the orginal masterpiece was gone forever (the surround sound).

The main Aud-X project task was to bring to people an easy technology for encoding Divx/Xvid movies with 5.1 sound the same way they used to do it with the simple mp3 stereo encoders. Since Aud-X 5.1 sounds great at 128 kbps and is compatible with AVI – you can reencode DVDs the same way you are used to, but with full surround sound.

In fact Aud-X 5.1 is a whole set of software tools compatible with Windows system aiming at 5.1 compression for movies and music. It allows for very effective and easy encoding of surround (5.1) sound that is compatible with the AVI file container. In addition, the decoder is based on DirectShow interface, thus may be used in any Windows system media player supporting DirectShow filters.

The great feature is backwards mp3 compatibility for devices not supporting Aud-X format and real-time AC3 transcoding within the DirectShow filter for external home theatre systems.

Here are some key features of Aud-X 5.1 Surround Codec:
· Dolby Digital compatibility. Designed to work with stand alone home movie theater amplifiers (AC3 in/out compatibility)
· Full scalability. Aud-X track can be played on any speaker and sound card set-up.
