Machines with File and Edit capabilities, known as Professional Voice Recorders, will allow you to record a file and then rewind back to a particular point in the recording to either:
INSERT - Add audio at a particular point without deleting any previous audio that has been recorded.
(e.g. adding the date to the beginning of a report without effecting any previous recording).
Or
OVERWRITE - Add audio at a particular point, thus deleting any audio that was recorded previously.
(e.g. deleting a particular word or phrase by recording a new one, for use with making corrections.)
File and edit capabilities are a must-have for any professional when recording letters, reports or taking notes in a professional environment.
Recorders without File and Edit
A machine without File & Edit capabilities is known as a Note Taker.These machines are ideal for recording blocks of audio such as meetings and interviews and even lectures.
However, be careful as once you record a file you cannot re-enter and edit any of the audio.
You can only pause a recording, but every time you stop recording, you will begin a new file. This means that you cannot rewind and overwrite an error.
