Opinions needed for new project

Hi,

I have been developing embedded applications for PICs but am new to
DSP and would appreciate a little "getting started" guidance on a new
project.

I need to develop a low cost battery-operated system that will record
and then playback 5 minutes of one-channel 16 bit audio sampled at 20
to 30 KHz. Most important: cheap and low power consumption.

Any ideas about suitable hardware and development environments would
be greatly appreciated.

Thanks. Start a New Thread

Howdy John,

Check out Danville - http://www.danvillesignal.com/
They have a wide range of platforms you could pick from.
They will also be happy to suggest what would work best
for your application.

Patience, persistence, truth,
Dr. mike

You hardly need a DSP for such a modest app. A higher-end PIC would do the trick.

PIC also has DSP version which will be enough for your app and is a lot
cheaper than a Blackfin. A Blackfin would be overkill for you. An
Atmel AVR is also suffice.
