Persono is a free application that provides an Audio Control Centre for the Plantronic range of Digital Signal Processing (DSP) headsets. With this centre, the user can set the volume and equalisation profile for the headphones as well as the volume of the integral microphone.
In the headphone tab, a number of equalisation options can be chosen depending on the preferred audio material, including classical, R&B, games and voice.
The voice setting is very useful in conference calls when a lot of background noise is present, as it enhances the voice frequencies, thus enabling the listener to pick out the dialogue with ease. Althernatively, the user can adjust balance, bass and treble settings manually. A speaker test option is also available to ensure that the headphones are working correctly.
On activation, the application runs in the background and is accessible via the system tray. Double clicking on this icon opens the Audio Control Centre. The audio control centre dialog box can be adjusted and supports three sizes to minimise its obstruction of the PC screen when in use. For example, when fully minimised only the menu options in the title bar are visible.
Plantronic indicate that this software is not supported on the Windows Vista platform. Instead, they suggest using the default windows drivers for their headset in this case.
