DSOAL ~ DirectSound DLL Replacement


This project is for a DirectSound DLL replacement. It implements the DirectSound interfaces by translating the calls to OpenAL, and fools applications into thinking there is a hardware accelerated sound device. EAX is also implemented (up to version 4) by using OpenAL’s EAX extension, allowing for environmental reverb with sound obstruction and occlusion effects.

Effectively, this allows DirectSound applications to enable their DirectSound3D acceleration path, and turn on EAX. The actual processing is being done by OpenAL with no hardware acceleration requirement, allowing it to work on systems where audio acceleration is not otherwise available.

Or more succinctly: it enables DirectSound3D surround sound and EAX for systems without the requisite hardware.

Crystal Mixer ~ ASIO Driver / OpenAL Output


Crystal Mixer is based on the OpenAL engine surround sound mixer. It supports up to 8 direct output and input channels and up to 18 output channels through a 3D mixer. It works through the ASIO Driver API for versatility. It’s possible to use up to 15 customizable auxiliary effects. It is also possible to enable hardware acceleration with some sound cards.

Features:

  • Multichannel surround sound support
  • Up to 8 native input and output channels
  • Up to 18 output channels mixing in 3D space
  • Auxiliary EFX and EAX20 effects
  • Reverb, Echo, Chorus, Flanger and others effects
  • Sound rotation and position changing
  • Source positions visual control with 3D view (OpenGL required)
  • Hardware Acceleration with native OpenAL driver
  • 3D movement effects
