Playback functions

Featuring an array of playback features to accommodate your needs, such as the Voice Balancer for easy listening through equalisation of volume levels.


Voice Balancer delivers audio quality that is easier to hear

When voices are recorded at different volume levels due to the distance and physical relationship to the recorder, you can use the Voice Balancer to automatically make smaller voices louder, and ensure that louder voices stay below a given level, providing playback where everyone can be heard clearly. This comes in handy when recording sound sources from multiple positions, such as in a large meeting or conference. Since the voice filter operates simultaneously, the prominent noise produced when amplifying small sounds is also reduced. By eliminating the lower and higher frequencies during playback, recorded voice is even further enhanced. This enables much clearer playback than the functions offered by our competitors.

Noise cancellation for clear playback quality

The noise cancellation function powerfully reduces unwanted ambient noise such as air-conditioner noise or projector fan noise to enable clear playback quality. This function is very effective when playing back meeting recordings.

  • Some functions are limited when the noise cancellation is used.
  • Recording containing background noise
  • Recording with noise cancellation applied

Change the playback speed without changing the pitch "Fast/ Slow playback"

With fast or slow playback, the speed change is processed digitally, thus the pitch is not altered resulting in the voice remaining as recorded. The playback speed can be adjusted between a range of ×0.5 (slowest) and ×2 (fastest). The ability to change the playback speed is particularly useful when you want to quickly check meeting recordings, or when recordings need to be listened to repeatedly such as with language study. The playback speed settings are retained even when the recorder power is off, making it convenient to resume.
