View Full Version : Stereo Audio DAC and ADC drivers updated!

They now no longer suck!!! =). There are also nice demo's for each included with both of them.

http://obex.parallax.com/objects/566/ - Audio ADC.
http://obex.parallax.com/objects/567/ - Audio DAC.

Both of these drivers were designed to give the user an easy way to play and record wav files. The drivers also have hooks in them for visualization and quick and easy sampling vs using data dump transfers.


I also have updated all my other drivers in the OBEX. Don't feel like spaming the fourm about all 22 however.

Hi Kye

Thanks great work !

Im totaly beginner in propeller demo board please help me with your DAC engine.

My idea is precise sine wave routing to StereoSpatializer.spin (or delay and other effect routine) and route to your stereo DAC engine.

Is possible making this with propeller chip ?

Many thanks help

The stereo spatilizer can output audio on its own. I would use my DAC driver only for playing wav files or other large chunks of LPCM data.
