PaulS,
I'm not guessing, let me rephrase. I can produce signals from MatLab that can be then fed into the Arduino via USB using the MatLab interface.
The kind of signals I wish to deal with are trying to imitate daily signals (for the sake of the project), such as speech and music. I have to load those signals onto the arduino, and filter it using FIR or IIR filters.
And an ECG (Electro Cardio Graph) signal can be made by summing it's individual PQRST segments.
jremington,
Yes it can read analog voltages, but how do I connect an AUX cable to a jumper wire that's connected to an analog input pin? I was trying to somehow transfer audio from my computer via USB, but there doesn't seem to be an application that can do that.
Also, is there any way to "slow down" a real-time audio signal to ensure no data gets lost in the 10-bit ADC?
horace,
Apparently I need to use an Arduino. Also, I don't think I'd require a DSP if I was somehow able to make the audio signals more processable before feeding them into the board.
