The DSMixer component provides playback of several audio files simultaneously providing good sound quality enabling per channel control of volume, pan, pitch, fading and also access to each channel audio data in PCM format while playing. And the best of all... it's freeware!
This component makes use of DirectSound 1.0 or higher for sound output and DirectShow for audio file loading and decompress. The audio files supported depends solely on the installed DirectShow audio codecs.
Both DirectSound and DirectShow are now part of DirectX, for more information please refer to http://www.microsoft.com/directx/. To keep it simple... you may install all the needed DirectX components by installing the latest version of Windows Media Player.
First of all you need the JEDI Graphix DirectX8 headers, available for download at http://www.delphi-jedi.org/DelphiGraphics/jedi-index.htm, and make sure you add the path for these units to your library search path before compiling.
To install the component select Component | Install Component... and choose cbDSMixer.pas as the unit file name. This will install DSMixer on the additional tab and also ThreadedTimer on the system tab. The ThreadedTimer component is internally used by DSMixer so you must have it's code also.
Support is provided via an EzBoard Forum, which is a web-based message system. You can find it at Carlos Barbosa's Code Discussion. The DSMixer source code is provided free of charge. As such, I can not guarantee any support whatsoever. While I do try to answer all questions that I receive, and address all problems that are reported to me, you must understand that I simply can not guarantee that this will always be so.
