856452fc2a Spell the largest 32bit signed value as INT32_MAX. Explicitly cast to 
float, because it is not precisely representable.

95676db785 add support for playing IEEE float32 and float64 RIFF WAVE 
samples on platforms that have these types natively, and
can handle signed linear 32 bit samples.  explicitly
disabled on vax, run-or-compile-time sizeof() check
disabled for everyone else

now i can play a float32 .wav file i found.
float64 not tested.

copyright maint, update HISTORY, update audio drivers list.

cf3b979950 Renane ioctl AUDIO_SETPROC to AUDIO_SETCHAN. 
Add an ioctl to return channel number (AUDIO_GETCHAN). This can be used
on audio/sound/audioctl devices.

Return EIO in read/write/ioctl/poll/stat if fp has been closed or is
invalid.

Update audio.4, audioio.h and audioctl(1) to reflect these changes.

f835d36292 Audio now uses fdclone, there is no longer a limitation of one audio 
instance per process.  Virtual channels are placed in a queue, so there is
no longer a compile time limit of VAUDIOCHANS.

A new sysctl has been added to control multiple user access.
Mixer labels on virtual channels are now prefixed by vchan.

audiobell.c and audioctl have been updated to reflect these changes.

Use of fdclone was posted to tech-kern@ and improvements made.
Multiuser access control changes and the use of a queue were suggessted by
pgoyette@

82924a36bf The audio sub-system now supports the following features as 
posted to tech-kern:

    * Simultaneous playback and mixing of multiple streams
    * Playback streams can be of different encoding, frequency, precision
      and number of channels
    * Simultaneous recording to different formats
    * One audio device per process
    * Sysctls to set the common format frequency, precision and channels
    * Independent mixer controls for recording/playback per stream
    * Utilizes little cpu time for multiple streams / good performance
    * Compatible with existing programs that use OSS/NetBSD audio
    * Changes to audioctl(1) to allow specifying process id for corresponding
      audio device

3a70beec89 separate the 3 functions midirecord uses from libaudio.a into its own 
file and link it directly, instead of having an (implicit) dependancy
on usr.bin/audio/common being built before usr.bin/midirecord is linked.

0c2e06460b move most of the header writing code from record.c into wav.c and sun.c. 
introduce a struct write_info for communication between front ends and
backends.

libaudio API is still pretty ugly, and needs to stay local here for now,
but it is a little more usable for other tools now.
