Yes, I believe you can specify (d600) to record the sound for 10 minutes as opposed to letting the subject hit continue when they are done. The sound files are saved as .wav files, so you would need to specify a file name like mysound.wav. You can download and install a freeware app called Audacity from www.download.com. It will allow you to open, play and convert your sound files to any format you like (e.g., mp3).
