Default DSP module with AD-DA

Hi!

Anyone who knows of any good simple audio DSP module with on board AD and DA? I do not need more than 1I/1O, but I know many such modules has a few more. I can off course live with that.

What do you want to do with it? TI's TAS3004 has built-in A/D and D/A, plus digital in/out, but it is not a general purpose DSP. It is a special DSP with fixed functionality including EQ, bass/treble, dynamic range compression/expansion, delay/reverb/3D effects, and volume control. It does not require writing DSP code... you just set parameters to control each function.

Thanks! That is in many ways what I want to do with it. Do you know the basic data for it? (Dynamic range, bits/frequency, THD and so on).

I am first of all looking for a parametric equalizer with good capacity.

Also look at the Analog Devices Blackfin parts. The BF537 ezkit eval board had ethernet input, analog in and out, I2S, I2C, SPI, and with an optional board has multi-channel in and out, plus SP/DIF in and out.

Worth a look. There development tools are great as well, like VisualAudio which is a graphical DSP design tool. The developer tools are free to download. BTW the Blackfin supports ucLinux.
