Abstract
A method and a device for equalizing audio signals, where the method includes: obtaining an audio signal (S401); acquiring an echo estimate that is caused by a sound reflection off one or more objects (S403); acquiring correction data based on the audio signal and the echo estimate (S405); and equalizing the audio signal based on the correction data (S407). Accordingly, by virtue of the method and the device for equalizing audio signals, equalization can be performed automatically in real time to match an audio signal to a desired reference frequency response with consideration of spatial acoustics, such as indirect echoes.
