As a opera singer looking to record my lessons in a small studio, I have been very pleased with this recorder. While my voice is loud, and so is the piano, by changing the settings to low I rarely have any interference noise, and the quality of the recording is near CD quality!I don't write reviews, but I wanted to let any other singers know that I was very pleased and I highly recommend this recorder over the others (a friend at my conservatory has another one for the iPod Video that is no where near as good, he's selling hsi to buy this one).
