I am new to this so please bear with me. I have windows 7 pro and just downloaded audacity. I uploaded a .wav file that needs to be saves in 8-bit, 8khz, mono. The program defaults it to 32-bit, 8khz, mono. I see I can change it to 16 bit but can’t find an option to save it as 8 bit. Has to be 8 bit for my phone system - any assistance is appreciated.
