Roman Black Sound (btc)

**ScaleRobotics** · - 25th May 2010, 16:44

Here are some number sound files and Darrel Taylor's example program that allow your PIC chip to talk out numbers to you. The RB sound files are pretty scratchy, so if you want a professional sounding product, this is not the way to do it. But it is understandable, and sure beats counting the flashes of an LED. It also uses a lot of storage space for the sound files. But the fact that you can store them on a chip, is pretty cool. Darrel's RB_Sound include file was used, as well as his testRBsound program . Check out post # 5 for his post in this thread.

Here is the suggested filter (Roman Black) that may make it sound a little better.

The attached audio sample audio-sound-mp3.zip using a 18f4550 in PIC-USB-STK hardware from Olimex. But you can also get similar sound out of a non amplified piezo speaker using a 5uf capacitor.
