摘要:
Embodiments included herein generally relate to managing low frequencies of an output signal. For example, a method may include: measuring a sound pressure level (SPL) of a speaker; dynamically selecting a cutoff frequency for operating a first filter configured to provide a first bass component of a bass element of an output signal and a second filter configured to provide a second bass component of the bass element; providing the cutoff frequency to the first filter to configure the first filter to generate the first bass component based on the cutoff frequency; providing the cutoff frequency to the second filter to configure the second filter to generate the second bass component based on the cutoff frequency; and generating an output signal based on at least one of the first and second bass components.
