Choosing DSP for portable sound recorder project

[salohcin]

hi all i currently doing a project portable sound recorder
as it portable i plan to use 2 AA batteries to power it
and since i will using compression to store more recorded sound, the DSP have to be fast

so how does one goes in choosing a suitable respective DSP to suit their criterias?
like for now i plan to use a 16 ADC/DAC after a band pass or a low pass filter before my DAC

I believe the commercially-made audio recorders compress in real-time as they record. The result is an mp3 file.

Is this what you want to do?

not really it a engineering project which i have to record a speech then run it through a dsp for compression and saving it and through interface i will be able to pull the data out and play it back via the speaker
