Abstract
A source device uses a profile of an audio output device (e.g., headphones or speakers) to adjust the acoustic output of the audio output device. A database of audio output device profiles is stored in a cloud or locally on the source device. The profiles may include electroacoustic measurement data characterizing the audio output device or processing parameters for the audio output device. A program running on the source device selects a profile corresponding to the connected audio output device. The profile is used by the software running on the source device to determine processing for an audio stream played by the audio output device. The processing provides equalization to modify the unique audio output device frequency response, and compensation for human perception of sound at different listening levels, and dynamic range adjustment to better match the capabilities of the audio output device.
