Recommendation for a processor for first project

Hey guys,

I have mostly analog or general uC background and I'm looking for a recommendation for a DSP for first and further projects. I'm mainly working on audio-projects for musical instruments, meaning filters, reverbs, delays. As a first projects I'd like to implement an impulse response loader for a length of at least 100ms. Before I get started I want to hear your opinion on what would be the right plattform.

My preferred ideas so far:

1. ADAU1701+uC with DSP functionality (e.g. STM32F4) and Memory (very cheap, not sure if the performance will be good enough)

2. ADAU1452+Codec+small uC (not sure if the performance will be good enough)

3. Small SHARK or Blackfin Processor, preferably programmable via Sigma Studio (very expensive)

I'd like to hear your opinions or alternative ideas on the issue

Thanks, looking forward

Dennis

Edit Notes
name of processor was spelled wrong
