There are a variety of recording systems available, suitable for dictation to conference recording. If you already have a digital recording mechanism, there is a good chance that it will record a variety of different file types for different purposes. This article aims to discuss these different types and suggest the right one for you, depending on your circumstances. If you are still considering which digital recording device to purchase then you have the opportunity to consider the file types it will produce before you buy.
