Summary: Have used this for 6 or more years, now 2011. I use it with Win 7 just as a microphone though as Olympus has not offered Win 7 drivers for the program that works mostly on XP. I liked it with XP because the files sizes were smaller than most MP3 and similar voice files. Now I use Recordpad from[...] as the program and with the DS330 as the microphone.
Summary: With so many reviews already available here, let me avoid going over the same ground. This is a great instrument with one serious annoyance. I use it in taking biological research notes in the field, and for trail notes when hiking and backpacking. The annoyance is having the STOP button immediately below the PLAY button. Despite years of use now, I still manage to press the latter when trying to end a recording.
Summary: I did a lot of research before finally plunking down the cash to buy this recorder, and I'm glad I did my due diligence. The Olympus DS-330 is a very solid digital voice recorder, packing a lot of functionality into a small package (as an aside, Sony does make them smaller, but IMHO, too small gets to be unusable). First the features: Files are recorded in DSS (Digital Speech Standard), but the PC/Mac software allows you to convert files into WAV format.
Summary: I am a newspaper reporter for a living and I have been looking for a good/great digital voice recorder. This is the best I've found so far. Like other reviewers, I found that my Dell with Windows XP also had trouble installing the driver. (However, once I figured out what was wrong, the situation was easily corrected by directing the driver search function directly to the software CD that came with the recorder).
Summary: I just bought this so take my review with some salt, but still this seems like a pretty cool toy. It's very small, very lightweight, and has a lot of features. Voice activation, 2.5 hours at good quality, usb interface with your computer. The voice activation feature works quite well (just turn your recorder on and leave it in a room to find out what happens when you're gone: very James Bond).
Summary: I purchased the DS-330 for the purpose of recording meetings of my Association. Usually 8-12 persons attend the meetings and are seated around a large conference table. I haven't yet been able to use the recorder at an actual meeting, but I have simulated the same conditions,testing the recorder, and found it quite suitable for the task. I learned to operate the DS-330 by trial and error rather than resorting to the Instruction Manual that accompanies the recorder.
Summary: I've read some of the reviews about the recorder being able to record lectures really well, even from far away, but I've found that this recorder will pick up more of the surrounding noise than the lecture if you're more than 6-10ft away from the person speaking. I really love the fact that you can store and listen to recordings on your computer. It definitely saves money and space from regular tape recorders. The battery life I've found last maybe around 2 weeks.
Summary: I bought the DS330 to record interviews and meeting with clients and prospective clients. It works just fine, and provides over 2 1/2 hours of high quality recording - more than enough for 95% of all meetings. I especially like the feature that allows users to download recorded sound files directly to their PCs. That's a big timesaver and excellent organizational feature. Setup was fast and easy. And the software works as advertised.
