Summary: If you want to use a good external microphone (USUALLY STEREO) or record from external source using the micro jack as LINE IN, and don't want the automatic SHQ setting, just use a 3.5 stereo to mono adapter (both channels are merged) and VOILA, a lot of selectable good quality (HQ or SP) recording time. About the recorder. . . sorry for my other ones (SONY) but ever since I got the DM-20, only use it. The difference (quality of recordings) is awesome.
Summary: I recently ordered olympus digital voice recorder DM20 from amazon.com. it was the cheapest price after compairing it to tons of stores. it was shipped the same day i placed the order and with Free shipping i receieved it in 6days. overall i was very satisfied with Amazon's service. DM20 itself is really good, very light and compact. the recording was clear and i was able to download a 2hr recorded file in less than 5sec.
Summary: I'm a professional journalist and I purchased the DM-20 to record interviews (I do about two-three interviews a week on average). While I had excellent results using my DM-20 for the first two months, recording about 60 interviews 10 - 30 minutes in length, I had the misfortune of a 60-minute file becoming "lost.
Summary: I've been using my Olympus DM-20 for two months and am completely satisfied with its design and operation. I do linguistic fieldwork in rural areas, and have never been satisfied with cassette recorders. I wanted to switch to an all-digital recorder, but usually felt those recorders weren't up to the task, due to limitations of memory or of supported file formats. The DM-20 meets all of my needs.
Summary: This device couldn't be more intuitive. Without having to look at the technical manual, I was able to get the thing set up, record multiple tracks, and download the tracks to my computer. All this within about five minutes of taking it out of the box. I've been using this for recording interviews, as well as music tracks from my mariachi band so I can learn the songs.
Summary: I just recently bought the dm-20 and absolutely love it!!! I use it for lectures and the sound comes out crisp and clear on sp mode. I like it even more because I can index all of the portions of the lecture that i want to go back to. The dm-20 body design is very sturdy and convenient for its size. You can even reduce background noise so that it is easier to hear the professor talking.
Summary: I've been using this recorder for about a month, buying it after reading a few reviews about its great sound quality. At first when I recorded my voice and then played it back in what I thought was HQ, I was somewhat dissapointed since it sounded okay, but not anything special. Then I realized it wasn't set at HQ, but at SP. So I tried again on HQ and was blown away. It didn't even sound like a recording, it sounded crystal clear and lifelike.
Summary: I really love my little Olympus DM-20 Digital Voice Recorder. The price can cause one to take a step back, but it really is worth it. I am a qualitative researcher in sociology and it sucks to have completed an interview and then to play back the recording and find out you can't understand a word that was said. I am impressed with the quality of sound provided by the DM-20.
Summary: I just purchased a DM-20 for around $200... and that might have been a mistake. If only I had done my research by looking at Olympus's own web site more closely rather than spending all my time on user reviews. The specs are all there on Olympus America's site! Battery life, sound quality (in terms of frequency response, bitrates, and sampling rates), how much memory they have, and whether they record in WMA or DSS format. Who would have thought.
Summary: I use the recorder in college to record lectures and classes, and I have been extremely satisfied with the quality and ability of the DM 20. I have classes in rooms as large as 40' x 20' and record on HQ mode. My Prof's range from the screamer to the mumbler and even at 30' the recorder picks up the mumbler clearly, (after I turn the noise reduction feature to high).
