What I'm seeing are boards that can record for 1-2 minutes max, and I wanted to know if it were feasible to record for up to 30 minutes.
It should be obvious that the limit is the amount of memory available to store the data. The Arduino has no where near enough memory to store anything like 30 minutes worth of audio data, even an unrealistically low sampling rates.
Does that mean there's no possibility of having the data write to an microsd card?
