Aud-X 5.1 Surround Codec 1.23
Aud-X is the kind of a break-through in surround sound that was once made for video by Divx/Xvid more>>
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.
Main features:
- 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. You can use stereo speakers (by switching the DirectShow decoder to stereo mode), use your PC 5.1 speakers set, or hook your PC to the home movie theater. If one day you will upgrade your sound system ? it will cost just to change the decoder setting to enjoy surround sound,
- Mp3 backwards compatibility for older software and hardware. On machines without Aud-X decoder installed, users will still be able to enjoy stereo or mono mp3 sound (depending on the encoded Aud-X quality option),
- AVI compatible. This function makes Aud-X perfect companion for Divx/Xvid encoded movies. It must be emphasized that Aud-X works good at 128 kbps (traditional mp3 bitrate for movie encoding),
- Avi, Ogg, Matroska, Mpeg containers compatibility,
- Complete solution. Aud-X comes with a complete set of tools for movie encoding and playback. We also support users with ?How to? guides at www.aud-x.com
- Wide range of encoding bitrates. Aud-X can create streams ranging from 80 to 192 kbits. You can choose preferred quality accordingly to your requirements
- 80 kbps - world record breaking compression bitrate for 5.1 sound. Such a low surround sound bitrate allows for successful multichanel Internet audio streaming,
- Easy to use interface. Designed for non experienced PC users not, only multimedia professionals and software freaks,
- Web site support. FAQ?s and HOW_TO?s at www.aud-x.com
- High sound quality. Tests show that Aud-X outperforms other multichannel encoding technologies at comparable bitrates,
- Built-in Pseudo Surround module. You can choose to listen to your old mp3 stereo records with Aud-X DirectShow decoder. Stereo sound will be converted on the fly to 5.1 format with sophisticated algorithm that adds new spatial feeling to your tunes / movies.

Miles Sound Tools 7.0t
The Miles Sound System is one of the most popular game-technology libraries ever published. more>>
John Miles first wrote MSS as a hardware driver layer for a handful of sound cards back in the early days of MS-DOS gaming. Today, Miles features a no-compromise API that integrates 2D and 3D digital audio with features like streaming, environmental reverb, multistage DSP filtering, ADPCM decompression, and MP3 decompression.
With Miles, you can add features as diverse as digital audio recording, Red Book (CD audio) support, low-bandwidth Internet voice chat codecs, and 3D technologies like EAX, SRS Circle Surround and Dolby Surround to your game in no time at all. Check out the SDK features page for more details.
Miless coverage is so extensive that the only way to create a similar set of features would be to combine half a dozen other sound products. You cant go wrong with Miles! Check out some of the good reasons to use Miles here.
In 1998, Game Developer Magazine inducted the Miles Sound System into its Front Line Hall of Fame - the first middleware package ever to receive that honor. Over the years, John Miles and Jeff Roberts have designed and refined the Miles API over the years to be the best possible solution for your games audio needs.
Miles works like the sound system that you would write yourself. Everyone who uses the DirectSound API begins by writing their own wrapper layer, but most developers use the Miles API directly - its that easy and convenient!
The Miles Sound System is available for Windows 95, 98, Me, NT, 2000, XP, MacOS 9 and MacOS X (Carbon), and Microsoft Xbox. Versions for PS/2 and Xbox 360 are coming soon.

DivX Free Codec 1
Enjoy various media files using popular audio and video codecs. more>>
DivX Free Codec 1 is an amazing application for you! It includes DirectVobSub (vsfilter), AC3Filter, and FFDSHOW.
- DirectVobSub (vsfilter)
-
- DirectVobSub is a tool for displaying subtitles. Your subtitle file should have the same filename as your video file (for example Movie.avi and Movie.sub) and should be in the same folder as your video file. Then the subtitles will automatically be displayed in most players.
- DirectVobSub is simply a DirectShow filter which can be used to display subtitle. It integrates automatically with any DirectShow player like the Windows Media Player, Media Player Classic, The Core Media Player and others.
- AC3Filter
-
- AC3Filter is a high quality free DirectShow filter designed for real time audio decoding and processing.
- It has a priority on wide functionality and convenient settings. Filter can decode following audio formats: AC3/DTS/MPEG Audio. It also supports multi-channel and digital (SPDIF) outputs.
- FFDSHOW
-
- FFDSHOW is a DirectShow decoding filter for decompressing DivX, XviD, H.264, FLV1, WMV, MPEG-1 and MPEG-2, MPEG-4 movies. It uses libavcodec from ffmpeg project for video decompression, postprocessing code from mplayer to enhance visual quality of low bitrate movies, and is based on original DirectShow filter from XviD, which is GPL'ed educational implementation of MPEG4 encoder.
- First of all, the FFDSHOW consumes way less CPU power than original DivX codecs, even with maximum post-processing. At the same time the post-processing seems to give excellent quality results and allows more configuring than the original DivX 5 codec. It can even automatically reduce post-processing if your CPU is getting overloaded. The noise filter adds a kind of a rasterising effect to the picture - might be useful in some cases. The alpha version also includes experimental playback for MPEG-1 and MPEG-2 files (such as VCD and SVCD movies), which works pretty damn well. Only problem is that MPEG-2 playback can't play the SVCD clips directly from the CD, but requires the video to be extracted to the HDD by using VCDGear first. It uses libavcodec from ffmpeg project for video decompression, postprocessing code from mplayer to enhance visual quality of low bitrate movies, and is based on original DirectShow filter from XviD, which is GPL'ed educational implementation of MPEG4 encoder.

ATSurround Processor for Winamp 0.1.6
Extract the encoded surround information for playback on a 5.1 PC system more>> Extract the encoded surround information for playback on a 5.1 PC system
The ATSurround Processor is a DSP plugin for the Winamp audio player
Today many songs found on MP3s, CDs, etc. have surround information encoded. Even when played on a 5.1 PC system, the surround channels may not be extracted from the audio as it is processed from start to finish as a 2 channel source. What you get as a result is simply many speakers playing exactly the same sound, which does not enhance the audio. A surround decoder such as the ATSurround Processor is required to extract the encoded surround information for playback.
The process of extracting surround channels and routing it to the appropriate speaker is known as matrix decoding. Hardware and software decoders are available for this purpose. The ATSurround Processor is a software decoder designed to work as a plugin in the foobar2000 and Winamp players. Multichannel output capable soundcard and speakers are required.
The Headphone mode allows the listening of audio sources which sound like theyre really coming from a live 5 point surround system. Music no longer sounds like its "inside" your head, listening fatigue is thus reduced. Perfect when you dont want to disturb anybody around you by using headphones, but dont want to sacrifice the surround decoding capability of ATSurround.
ATSurround Processor is also capable of performing matrix encoding. The Processor receives multichannel audio and matrixes it into stereo. This stereo output may be distributed via any 2 channel medium, such as CD-Audio and MP3 or direct to an external audio receiver which performs audio surround decoding, useful when the receiver is connected using a stereo cable.
Main features:
- Reproduces surround sound information present in many stereo audio material
- Headphone mode allows listening of audio in virtual surround
- Compatible with Dolby or similar processors
- Makes full use of your 5.1 speaker systems
