how to store wave or any other audio file into microcontroller flash or external flash .... after stroring file how to encode it to get in original form ...
.WAV files are typically composed of PCM sample data that can be simply written to a DAC at the appropriate rate.
".WAV files are typically composed of PCM sample data that can be simply written to a DAC at the appropriate rate."
But wouldn't it be almost too easy to just visit wikipedia and read up a bit on the format? Better continue to think of WAV data as black magic and hope to find some code that solves the problem without own involvement - investing own time has the danger of resulting in actual learning :p
