Quoted from adamross:
Do you happen to know what the name of the simple text file I would need to adjust music & voices
Download pinsound studio, put your recorded game file(.psrec) into the playback folder in the pinsound studio folder, start pinsound studio, click the advanced editing tab, load your psrec file and from the preview window you can select each sound and adjust gain/level etc. Remember to click the save tab after adjusting gain. You will get a confirmation in the info list below afterwards.
So, in pinsound studio you can playback your game and listen to all the sounds while editing levels. Really great tool.
When done, just copy the audio folder to your USB drive.
