Abstract
A priming signal processing technique modifies digital audio recordings to reduce the stress experienced by a listener's auditory system. A priming signal may reduce the instantaneous stress experienced by the auditory system during sudden changes in signal energy. The priming signal may leverage the temporal auditory masking, such that pre-signal priming additions may not result in obvious differences in perceived sounds.
Claims22
A method for reducing listener auditory system stress, the method including:
- analyzing an input audio waveform to identify a sudden signal energy change;
- generating a priming waveform, the priming waveform configured to reduce an instantaneous auditory system stress caused by the sudden signal energy change;
- delaying the input audio waveform to generate a delayed audio waveform;
- amplifying the delayed audio waveform by a look-ahead gain to generate an amplified delayed waveform;
- and
- combining the priming waveform and the amplified delayed waveform to generate an output audio waveform.
