Burn Audio to EPROM ?

[Kevin Mullins]

Anyone here ever dabble in burning an audio file such as a .wav to an EPROM for use in a playback device of sorts ?

I was kinda looking over this site - http://sm0vpo.com/eprom/wave_00.htm - but hadn't really sat down to fart with any of it yet.

I have an older Akman DS129 unit and had thought about playing with making some of my own pre-recorded "stuff" to use in it. It has a 27C040 ROM in it now that I will try to play with. (maybe put a motion sensor or something on it to trigger it, etc)

Just curious if anyone had any insight, tips, software suggestions, etc for converting a .wav or anything else to a usable file.

Well.....the manufacturer was kind enough to send me this little tidbit of info before trying to sell me a new $200 unit.

The DS129 uses ADPCM file format. Furthermore, the ADPCM file itself has to be organized to fit a particular eprom size using another software mkadr.exe.
These softwares are using the old x86 DOS platform and will not run on windows platform.

So I guess I'll be playing with some ADPCM formats.
(not that I have a clue about it)

Better? Mp3 triggerable playback at many price points.

I'll definitely take a browse through some of those just for kicks.

But my point was that I already have this little unit, so was just trying to make "some" sort of use out of it, even if it was just for playing around with random sound effects.
It works fine, but as of right now all I have is the old go-kart track rules announcement that is currently on the ROM that came with it.
(not very exciting) 
I've had this thing laying around for years now.

Here's a couple pics just for the heck of it.
There is a ton of jumpers I have yet to play with also.

sounds like you need to take a 16 bit WAV and convert it it a 4 bit ADPCM then convert THAT to a hex or bin file to write to the eeprom. WHEW!

i would first rip out the rom image and dump it on a computer. using a ADPCM to wav convertor see if it;s a direct dump...or if there is something else going on there.

the rom may have some code at the start with the audio tagged on to the end of the rom.... hard to say. but it could be some intersting hacking.
