Hello all,
I am looking for a way to digitally decode a WAV file and output a voltage level for every time sample. So for a 44.1kHz WAV file that would be a voltage level every 20µs. Is there any way to emulate digitally what a DAC does? I realize WAV files are PCM, so I'm not sure how to convert that to a time varying signal.
The goal is to output a voltage vs time plot from an audio recording, and then perform an FFT of that dataset. It seems like there should be some algorithm for doing this, but I have been unable to find anything online. Any suggestions or ideas would be greatly appreciated! Thanks in advance.
