Question: audio quality for guitar recordings?
Document: This recorder had a very understandable manual, and it performed very well. The tone quality of the recordings was outstanding.
I bought this recorder to use recording owls while my LS-7 was in the shop for repairs. I have used another DM-620 to record bird and frog vocalizations for about two years. They are rugged, highly capable machines that are quite user-friendly and produce spectacular professional-quality recordings under very difficult field conditions.
I loved this recorder when I first heard the quality of the recordings. I am a court reporter so it's very important that I get every single word dictated onto this recorder clearly, which it achieves.Well, I make a lot of recordings throughout the day, week, month. This recorder saves the recordings under a name like "DSJ2000698" which has no real rhyme or reason. WHY?
In my field, this can cost you your whole career. I have heard of court reporters losing audio of transcripts, and guilty/innocent verdicts being overthrown because of it.A simple "low battery beep" would have earned this recorder 5 stars. But I give it 2 simply because the audio quality is impeccable. I guess if it was hidden or you were secretly recording something would be the only reason you would ever appreciate not having that feature.Disappointing.
Also, it does pcm type files which can be really useful for nature recordings.
Easy to use. Great recordings. Earbuds that came with it are better than the ones I bought some time ago....
I work as a court reporter, and this is my backup recorder. I stick it on the table, set it to where it's reaching straight out and to the sides in a 180 degree angle, put it on the highest MP3 setting, and let it go. The recordings it makes have been fantastic!! Nice rich sound, clear as a bell, am very, very satisfied!!
Well worth the money when it comes to recording audio. I use it almost everyday and have to rarely charge it. I LOVE THIS THING.
I will check it on breaks to kind of see where it is and have an extra power cord on hand that I could charge it up some with should the need arise, so that would never be a worry.I had the DM-520 before this for about four years, was very happy with it, but there's no comparison IMO between the recordings achieved by the two. Happy I purchased, absolutely worth it for what I am using it for! !
A friend of mine borrowed this from me to record a breeding pair of Barn Owls nearly two years ago. The owls, other animals, and rain have done their part to try to destroy this recorder. My friend  has gotten with both the internal microphones and external microphones Cornell Ornithology Lab recordings-thousands of hours worth. One of these days, I'll get it back.
Answer: I work as a court reporter, use this for voice recording, which it does great at.  I also play drums and have tried it with a full band rehearsal.  Not so good with the drums; but I think if you were just using it for recording guitar, it would do very well.  Hope this helps.
