AudioTrack - GDC Trip Report Summary
GAME DEVELOPERS CONFERENCE
March 17-19, 1999

Beyond Stereo - 4 and 5.1 Channel Playback
------------------------------------------
Users/developers continue to voice their dissatisfaction with stereo playback
of spatial sound - most unaccellerated solutions with limited or no filtering
are little more than planar panning.  Except for Aureal and Diamond (an Aureal
technology parner), all the spatial audio venders at the show (Creative Labs, 
Sensura, Qsound Labs, Dolby) chose to show off their newest hardware/software 
with either quad or surround speaker playback systems.  Most used 4 speaker 
output taking advantage of DirectSound's M-to-N channel functionality.
However, Dolby was showing off the "Miles" product from RAD that output encoded
5.1 format.  As more home "entertainment" systems support multichannel playback
the 5.1 audio output option could grow to become the high-end target audio 
delivery system for console (Nintendo, Saga, ...) and computer game play.

Sun MUST develop a road map for multi-channel audio output support in Java
(thru JavaSound) and in general on Solaris workstation if we want any of the
entertainment development market.

EVALUATION ###@###.### 2002-04-11 Valid RFE and relatively easy to integrate by bypassing the BAE with direct output Mixers. ###@###.### 2003-08-18 Should work since mantis on Linux with ALSA and is planned for tiger with DirectSound, and direct access to Solaris Mixer. ###@###.### 2004-06-23 Marked as fixed in tiger (1.5). DirectAudio mixers provide multi-channel support. Advanced features for multi-channel like channel assignments are not yet available, handled in a separate RFE: 5067483.

PUBLIC COMMENTS This is fixed in 1.5 by adding DirectAudio mixers. They allow to play back and record from all installed soundcards, using all available channels.
