Abstract

A software product for optimizing sound reproduction by an audio system is disclosed. In one embodiment, the software includes an equalization engine for independently adjusting characteristics of an audio signal for each of a plurality of frequency bands. The software then passes the adjusted signal to a dynamics engine having independently adjustable attack and release thresholds and attack and release rate settings to enforce a maximum excursion limit of the speaker driver knowing the voltage-to-excursion relationship for the speaker driver. The software then passes the audio signal to a bass enhancement engine configured to boost all bass frequencies below a bass roll-off frequency of the speaker driver. The boosted signal is passed to a dedicated dynamics engine for the boosted bass frequencies, the dynamics engine again having independently adjustable attack and release thresholds and attack and release rate settings to enforce a maximum excursion limit of the speaker driver.
