There is at least one person in each of our CorelDRAW Unleashed Boot Camps that wants to do an audio recording of the discussion. That means I get to see all different types of voice recording devices. I’ve even used them myself when interviewing software engineers so that I can properly document their software.
In our most recent Boot Camp, one of the students had a combination pen and voice recorder. I wish I had asked the exact brand, but I didn’t. He got it as a present and felt that it would soon be thrown in the junk pile. Just the opposite, he really enjoyed it.
While the pen/voice recorder is very convenient, it doesn’t always create the best recordings and can be difficult to control. The Olympus DS-40 Digital Voice Recorder is a very nice option for recording classes such as the Boot Camp. It records up to 136 hours of audio and lasts for 30 hours on a battery charge. It can be purchased for less than $100.
If you need higher quality stereo audio, check out the Zoom H2 Handy Portable Stereo Recorder. The amount of audio you can record is dependent on the quality you choose and the size of the SD card inserted into the device. It costs around $165. One of these three devices should meet your needs if you are needing a portable way to record audio.
