Audio controlling apparatus, audio correction apparatus, and audio correction method

摘要

According to one embodiment, an audio controlling apparatus includes a first receiver configured to receive audio signal, a second receiver configured to receive environmental sound, a temporary gain calculator configured to calculate temporary gain based on environmental sound received by second receiver, a sound type determination module configured to determine sound type of main component of audio signal received by first receiver, and a gain controller configured to stabilize temporary gain that is calculated by temporary gain calculator and set gain, when it is determined that sound type of main component of audio signal received by first receiver is music.

主权项

1. An audio correction apparatus for correcting an audio signal, the audio correction apparatus comprising:
a first receiver configured to receive the audio signal; a second receiver configured to receive an environmental sound; a masking gain calculator configured to calculate a masking gain, based on the environmental sound received by the second receiver and the audio signal received by the first receiver; a sound type determination module configured to determine a sound type of a main component of the audio signal received by the first receiver; a gain controller configured to:
calculate a temporary gain based on the environmental sound received by the second receiver,convert the temporary gain into a first value falling within a preset range to limit fluctuations of the temporary gain, and set the first value as a corrected gain, when it is determined that the sound type of the main component of the audio signal received by the first receiver is music, andset the masking gain multiplied by a preset coefficient as the corrected gain, when it is determined that the sound type of the main component of the audio signal received by the first receiver is not music; an equalizer configured to correct the audio signal based on the corrected gain and provide a corrected audio signal.
