DYNAMIC ENVIRONMENTAL OVERLAY INSTABILITY DETECTION AND SUPPRESSION IN MEDIA-COMPENSATED PASS-THROUGH DEVICES

An audio processing method may involve receiving media input audio data corresponding to a media stream and headphone microphone input audio data, determining a media audio gain for at least one of a plurality of frequency bands of the media input audio data and determining a headphone microphone audio gain for at least one of a plurality of frequency bands of the headphone microphone input audio data. Determining the headphone microphone audio gain may involve determining a feedback risk control value, for at least one of the plurality of frequency bands, corresponding to a risk of headphone feedback between at least one external microphone of a headphone microphone system and at least one headphone speaker and determining a headphone microphone audio gain that will mitigate actual or potential headphone feedback in at least one of the plurality of frequency bands, based at least partly upon the feedback risk control value. 本发明涉及一种音频处理方法，其可涉及：接收对应于媒体流的媒体输入音频数据及头戴式耳机麦克风输入音频数据；确定所述媒体输入音频数据的多个频带中的至少一者的媒体音频增益；以及
