Espes: Link to the ffmpeg debuxer, and I doubt the Microsoft code dump is 'legal'

* Extension: xmv
* Company: [[Microsoft]]
* Samples: http://samples.mplayerhq.hu/game-formats/xmv/

XMV is the audio/video container format used on the [[Microsoft Xbox]] console. It is reportedly similar to [[ASF]] and typically contains [[WMV2]] video at 640x480 29.97, and CBR audio at 128k.

An open source demuxer exists in FFmpeg/libav: http://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=blob_plain;f=libavformat/xmv.c

Copyrighted Microsoft source code for a decoder/demuxer is also available: http://sourceforge.net/tracker/index.php?func=detail&aid=1097094&group_id=53761&atid=471491

XACT

Espes: It's also a Multimedia API, I guess

* Extensions: xwb, xsb, xgs

* Wikipedia article: https://en.wikipedia.org/wiki/Cross-platform_Audio_Creation_Tool

Cross-platform Audio Creation Tool (XACT) is a audio framework released as part of the DirectX SDK.

Distributed XACT projects consist of three file formats:

== Wave Banks (.xwb) ==
A file format containing a collection of waves
* Waves - the raw wave data in [[Microsoft Wave|WAV]], [[Audio Interchange File Format|AIFF]], [[Windows Media Audio 9|WMA]], [[Microsoft xWMA|xWMA]] or [[XMA]] formats

Open source parsers:
* [http://aluigi.altervista.org/papers.htm#unxwb unxwb]
* [https://github.com/mono/MonoGame/blob/develop3d/MonoGame.Framework/Audio/WaveBank.cs MonoGame]

== Sound Banks (.xsb) ==
A collection of sounds and cues

* Sounds - a sound has one or more waves together with properties like volume and pitch. Sounds are made up of tracks.
** Tracks - tracks are made up of events E.g. the simplest track has a Play Wave event
** Events - various actions that take place within a track. Actions include: Play, Stop, Set Volume, Set Pitch etc.
* Cues - a cue is used in code to trigger sounds. Each cue is made up of one or more sounds

== Global Settings (.xgs) ==
Defines rules and settings for sounds.

* Categories - sounds can be assigned to a category (only one each) that specifies certain rules like number of instances along with settings like volume. You could create a category for the sounds of one character in your game so they all have the same volume. There are three predefined categories: global, default and Music.
* Variables - these can be defined in the design stage and then referenced by the programmer in code to control Run-Time Parameter Controls
** Run-Time Parameter Controls - also known as 'sliders'. These allow the control of sound parameters as the sound plays. For example they could be used to control the pitch of a car engine sound so as the accelerator is pressed the pitch is changed
* DSP Effect Path Presets (DSPs) - allow effects like reverb to be applied to sounds
* Compression Presets - compression can be applied to waves or wave banks
