Abstract
Example methods and systems provide automatic audio equalization for online conferences. A target, ideal, audio frequency response for use in online conferencing audio can be designed and preset for reference, and the equalizer can operate in real time to reach the target frequency response for any input. The equalizer can selectively apply per-band equalization to the audio signal as needed to adjust an energy value for each of multiple frequency bands to produce an output audio signal that that can be, as an example, routed through meeting servers or other infrastructure to other conference participants. The equalization can compensate for conditions local to a speaker that would otherwise adversely affect audio quality.
