METHODS AND DEVICES FOR ADAPTIVE RINGTONE GENERATION

摘要

Disclosed are methods and devices (102) for adapting a ringtone in accordance with ambient noise. The method includes processing an ambient noise signal to determine an ambient noise volume (532). When there is an incoming communication (508) and it is determined that the ambient noise has a low ambient noise volume (541), a method can include generating a ringtone having a ringtone volume that is initially a low volume and increasing the ringtone volume over a predetermined period of time (542). A method can include applying a filter to the ringtone signal to increase a signal-to-noise ratio (674), the filter configured to increase an amplitude of a frequency that is not one of the predominant frequencies of the ambient noise and that the transducer (110) is configured to output according to the transducer frequency response (422).
