Digitized Sound in Coleco games

[ColecoGamer]

Is it possible to have digitized sound in a Coleco game? And is there a tool available to convert something like a .wav file into a format the Coleco will understand?

 

Ive searched the forums, but I couldnt find anything on the subject.

 

Any assistance on this matter will be greatly appreciated.

Voice can be played on the ISR using frequency decomposition of the voice in formants

If you need a general method you need to spend the whole CPU time in cycle accurate code and you can easily get 4bit PCM audio

Thank you for the information, Artrag. Do you know of any tools that will convert a digitized sound file to the Coleco?

If you use devkit of Daniel Bienvenu in C , you have the play_dsound function. And there is tool in the kit to convert wav to the format expected by the function. Wav2CVDS or something like that, i don't remember exactly the name. But i used it in some of my games. Like to do the voice in Battle of Hoth or in GameSter81 : The video game.

Thank you, Youki! I’ll check out Daniel’s devkit. I’m looking to add digital speech to my projects too.

That's very interesting because I've been working on a similar tool a while ago. But it runs way too slowly...

 

I guess that conversion wouldn't only work for the Colecovision, but for any video game or computer having a similar sound chip, right? Such as the Intellivision, MSX, Sega Master System, Sega Game Gear, Amstrad CPC, TI-99 etc. etc., given an appropriate player.

The tool Artrag mentioned is available here - it requires Matlab. I started a C conversion but that fell by the wayside. Notes on how to run it are included.

Thank you, Tursi! I’ll download the tool later today after work!
