Dynamic master tape processing method and device used for audio

Abstract

The invention discloses a dynamic master tape processing method and device for audio. The method comprises the steps of determining an input volume ratio of audio data to be processed; mixing the audio data to be processed according to preset logic and the input volume ratio and controlling the output volume range in the mixing process. The method and the device solve the technical problem that the accuracy of processing master tape is low. According to the method and the device, parameters used for processing the master tape are adaptively controlled, so that the time-varying mixing ratio ofderivative signals of dry sound, reverberation, echo and the like to an accompaniment is completed, and the dynamic range of output signals is ensured. In addition, the method and the device are applicable to singing scenes.

Description

technical field

[0001] The present application relates to the field of audio processing, in particular, to a method and device for dynamic mastering processing of audio. Background technique

[0002] Mastering processing refers to the adjustment of dry sound and the mixing of dry sound derivative signals and accompaniment through basic module tuning tools such as equalizers, mixers, crossovers, and dynamic range controllers. The common mastering method is to manually mix the dry sound and the dry sound derivative signal with the accompaniment ratio, and adjust the output amplitude after related processing.

[0003] The inventor found that manual adjustment has low precision and heavy workload. Further, it is impossible to adjust the parameters precisely according to the change of the accompaniment over time.

[0004] Aiming at the problem of low mastering processing accuracy in the related art, no effective solution has been proposed so far. Contents of the invention ...
