Request to Experts:
I am a DSP novice. I would like to experiment with some methods for low pass filtering in the time domain.
To that purpose, I would like to generate a tone in audacity and export it as a raw file (without headers), then process it using simple C/Java file handling programs (without using audio processing library), and then import it back into audacity and listen to it and plot its spectrum.
However, I am unable to find a way to export raw audio from audacity. Could you please guide me if/when free?
