Ever since the invention of the first sound recording device and reproduction instrument in the late 19th century, voice recorders have evolved from being just an ordinary tool to a powerful device that can be used for a variety of applications. Nowadays, voice recorders come in different shapes, sizes, and offer a variety of functions. We can find complicated voice recording systems in music studios and movie sets and there are those that are small, compact, and can be carried around wherever you may go. Because of the development of smaller voice recorders that can fit inside small items such as pens and flash drives, the popularity of spy microphones has recently gained traction as well.

While there are no set of standards that distinguish spy voice recorders from other types, it is important that microphones are small enough to fit inside compact cases. They must also have long battery life and file transfers must be quick and easy between devices. The size of the storage is also an important factor especially if you are planning to record long hours of conversations and discussions. Extra features may include wide audio detection range which can pick up sounds even several meters away from the device and noise cancellation mode which can isolate sounds and make it clearer in the playback. You may also need to check the sound quality of the recorder that it must not go down below 128 kbps, close to the sound quality that you can hear from the radio.
