I am using Arduino to get the voice value from the microphone to the ADC.
I send the ADC value to a PC and want save it as a .wav file.
In other words, how can I convert voice data to a .wav file?
A quick G search with keywords: convert raw adc data to wav provided the following promising post:
You can saw some raw data using Processing, or any other software and try running the raw-to-wav converter and see if it works for you. If it does, you could call this file from the PDE using the exec() command.
