I am looking for a dsp evaluation board for a proof-of-concept project at work, and I would appreciate some input on what to choose.
The project is fairly simple on the processing part: All I need to do is add some delay (probably 0-5 ms, max 20 ms), and attenuate the output (at least for now - if the proof-of-concept works, then perhaps it could be interesting to add more advanced stuff later. But my boss might prefer simpler and cheaper).
The problem is that this must take a single analog input, and produce at least 8 analog outputs with individual delays and attenuations (8 is the absolute minimum, but I would prefer having the option to have 12-16 or more outputs if possible).
Also, I have been looking at Audio DACs (https://www.analog.com/en/parametricsearch/11079), and noticed that some of them can be daisy-chained, which lead to the question: How many analog channels is it possible to support on a single digital channel?
