Abstract:
1. A method for improving the quality of a far-end audio signal for playback on a device in a noisy environment, said device having a single speaker and a microphone, said method comprising the steps of: continuously monitoring a near-end noise audio signal through the microphone; continuously determining near-end noise characteristics from said near-end noise audio signal; comparing said near-end noise characteristics from previous near-end noise characteristics to detect a change in said near-end noise audio signal; upon detecting a change identifying an optimal signal shaping filter based on said near-end noise characteristics; applying said optimal signal shaping filter to the far-end audio signal to produce an optimized far-end audio signal; outputting said optimized far-end audio signal to the speaker.
