Hiring an expert to create a new audio driver (Z80 based) - Hired and solved!

Post by masteries » Fri Aug 27, 2021 12:02 pm

Greetings mates,

After a week trying to write my own custom driver, with bad results;
its a very challenging task for a person that is used only to C language and a bit of 68k assembly


I decide to make this proposition:

3x ADPCM channels driver at 16 KHz ( 200€ ), or 14 KHz (170€)

integrated into current SGDK release, SGDK 1.65

Typical set of functions is required, such "start_play", "is_playing_channel", "stop_channel"...

Volume functions are not required,
Loops playback is also needed,

Briefly the same functionality of 2 ADPCM driver, but intended for 3 channels at 16 KHz, or 14 KHz if you can't manage it at 16 KHz


Thanks in advance,

Contact via private message,

Best,

First be sure to check if that if physically possible. Then check if this configuration can work with your program/game running on.
HELP. Spanish TVs are brain washing people to be hostile to me.

Problem solved!

A Z80 expert was hired; a programmer that worked for ZX Spectrum, Amtrad CPC and Genesis / MegaDrive

Its nationality is Argentinian,


There is also an implementation of a software audio filter, depending in the console model, due to MegaDrive 2 / Genesis 2 has worst audio output stage, this implementation is very helpful

He did a very good job, 3x ADPCM channels at 16 KHz;
sounds perfect!
