Abstract
A system and method automates the tuning of one or more hands-free library parameters. The system and method plays one or more test signals that vary in frequency and in amplitude out of a hands-free system under test or the hands-free tuning system and records the responses of a hands-free tuning system or hands-free tuning system at a microphone of the hands-free tuning system and a microphone of the hands-free system under test. The system and method measures the sound generation and sound pickup characteristics of the hands-free system under test or the hands-free system with respect to the one or more of the test signals and one or more of the microphone signals. The system and method calculates tunable parameters. The system and method updates a hands-free system library with the calculated plurality of tunable parameters.
