At times you may wish you had the capability to record a conversation so you can reference it in the future. If you frequently find yourself in this situation, it might make sense to purchase a Digital Voice Recorder. A rather inexpensive tool, digital voice recorders can be a great asset to review class notes, conference calls, meetings, and even recording personal conversations. Olympus VN and Olympus DP/WS/DR digital voice recorders are some of the more common digital voice recorders out there for a reason, they simply work great! Like with many digital voice recorders, these can simply be hooked up to your computer. Prices vary due to the amount of recording time and battery life each digital voice recorder possesses. For example, the Olympus VN-7200 gives it's user 1,151 hours of recording time in a small compact build for around $40.
Sony also makes recording devices such as the Sony ICD digital recording device models that do a comparable job to the Olympus digital voice recorders with roughly the same functions and price.
