The files in this archive (USBAUDIO.ZIP) are:

USBAUDIO.EXE  a demo plain DOS USB audio player which will play a WAV file
 (ver 1.1)    from 32-bit system memory (398630 bytes)

LOAD32.COM    loads a DOS file to 32-bit memory (2088 bytes)
              (optionally run before USBAUDIO to load a WAV file to be played)

System Requirements
~~~~~~~~~~~~~~~~~~~
Processor:      Pentium+ (486 probably OK)
Motherboard:    PCI bus with UHCI USB controller
Memory:         enough to hold the 16-bit stereo WAV file to be played
                (about 12MB per minute of audio)
Speakers:       USB stereo speakers or
                USB Headset Device with headphones or amplified speakers
DOS options:    DR-DOS 6.0+, NovellDOS 7.0+, MS-DOS 7.0+, FreeDOS 0.83b+


Please note:    USBAUDIO v1.0 expects the WAV file to be sampled at 48 kHz.
                You can play 44.1 kHz files ripped from audio CDs but they
                will sound slightly higher-pitched than normal. Alternatively
                a program like WAVEPAD can be used to save 48 kHz WAV files.


USBAUDIO and LOAD32 are freeware demos, but can be customised on request to
neville (at) watkintechnology (dot) com, or  neville (at) fa-mos (dot) com.

Updates
~~~~~~~
21 Sept 2008    USB audio device enumeration changed to allow for some
                devices' tendencies to enter the "stalled" state
                (should further increase overall reliability)
10 July 2008    original release
