Add a profile for corresponding sound environment so that Petralex can process the sound properly and make the speech more intelligible. You can quickly switch between all your profiles.
Petralex uses complex algorithms of sound processing with non-linear amplification. This means that you will hear quiet sounds and speech better while loud sounds remain on the same level.
The sound in the device is equalized in such a way that quiet sounds are amplified in accordance with set parameters while loud ones remain on the same level. You can use other products of our company to listen to music or radio. Unfortunately, this function is not available yet.
Since mobile phone manufacturers do not provide access to the required modules to external developers, Petralex cannot process the sound during phone calls.
However, soon we are going to add an option of voice communication between Petralex users and telephone network subscribers. When the volume of the phone is set at maximum and the function of Acoustic feedback suppression is on, the white noise is amplified too much.
