Someone asked me to mix a song for him. He basically recorded voice, guitar and bass. He asked me to record drum loops. He only had the song as a full mp3 and not as single tracks, so when I open the file is a stereo track. I recorded the drums with a midi in another track. When I bounce both tracks, and with standard parameters (128kbps, fast-low quality), the file ends up being like 28MB. What can I do to make this file a normal (less than 10MB) file? I tried lowering the the rate to 48kbps and the size was still > 10 MB What can I do?
