Abstract:
Apparatuses, methods, computer readable mediums, and systems are described for combined dynamic processing and speaker protection for minimizing distortion in audio playback. In some embodiments, at least one compressed audio signal is received, at least one threshold for a speaker is retrieved, modifications to audio signal compression are determined based on the at least one compressed audio signal and the at least one threshold, information embodying the modifications is transmitted to a dynamic processor, and using the dynamic processor, at least one modified compressed audio signal is produced for the speaker based on the information.
