A digital voice recorder is a small portable device that records both human speech as well as any other sounds and converts it into a digital recording. They are for more superior (in terms of reproduction quality) to its analog counterpart i.e. cassette based recorders.
Today’s digital voice recorders do not require external media such as a cassette or even a USB cable to function. Rather, they rely on their own internal memory card for storing the digital recordings.
Many types of voice recorders do have a USB connection available as an option, allowing for further storage capabilities. Those who require extensive recording times should opt for a device that offers external memory capability. Such devices may be slightly pricier than their internal hard drive only counterparts. But, the value addition they bring is well worth the cost. Especially if the user plans on using the recorder for professional purposes.
Files created on a digital voice recorder are managed in a file system on both the internal hard drive and removable flash drive. These files can be easily played back for editing or transcription purposes. They can also be paired to a computer that has speech recognition software installed to easily turn speech to written text.
Typical sound files may be digitally recorded in MP3, WMA, WAV, DSS or other formats. Here each file format offers its own compression ratio depending on both sound quality as well as the ability to edit such files.
There are many devices available in the market. All of them offer different features such as enhanced battery life, sound quality, as well as external connectivity. Settings on most devices can easily be adjusted based on their application.
Digital voice recorders are to the 21st century what cassettes were to the later decades of the last century.
As with many other technological breakthroughs, it was not a “wonder machine” from the get-go. Rather, it was a bulky alternative to many analogue machines found in those early days. But as time passed, the digital voice recorder continued to evolve. Today’s highly versatile devices can handle truly prodigious amounts of data.
