Thank-you Olin, this looks exactly like the sort of thing I'm after, but I =
can't get wav_hal.exe to work.
I used:

C:\WINDOWS\Desktop\hal\embedinc\com\wav_hal.exe winex.wav

It gave me a lot of data about the wav file structure, but no output file =
(that I could find)

I looked in the source, and saw <in> <out> so I tried:

C:\WINDOWS\Desktop\hal\embedinc\com\wav_hal.exe winex.wav output.aspic

It said something like 'Invalid token found on line 2, token was 'output.as=
pic'

So how am I supposed to use it :)

Although there is something that somebody may be able to help me with, a
long time ago I'm sure I read of someones efforts to reproduce sounds via
the PIC using a large RAM table with wave data in it, if anybody thinks =
they
know a link it would be greatly appriciated, as melodys are extreamly hard
to code as consecutive delays.

My HAL project produces audio from WAV data stored in program memory.  See
http://www.embedinc.com/pic/hal.htm.  The details of fetching the WAV =
data,
interpolating adjacent samples, and writing to the PWM output are in the
HAL_INTR.ASPIC module.
