The Sony I have has a pretty limited mic and noise ratio. It works for what I got it for (which was for conversations) cost about $70, but did not perform well enough (IMO) to work for your friend's desired purpose. It also saved in mp3 format so it *may* be the same unit.
What model # ?
I could record some piano with it and let your friend decide, if it is indeed the same unit.

As a side note; I swore never to buy Sony, but needed it in a hurry so I conceded in this case. Wish I could have waited a couple days for parent's music store to open, then I would have purchased a different brand for a little more that did a MUCH better job. The extra step of creating an mp3 file for the web from a better original recording would have been a moot point here; I'll gladly trade a couple minutes for a better end result.


I do not work here, but the benefits are still awesome
