Definitions
- the above noise reduction processing may include at least one of the following: DSP noise reduction algorithm processing, and residual echo suppression processing.
- the audio signal processing apparatus may use the second algorithm to obtain another noise reduction parameter based on the determined one default noise reduction parameter, and The other noise reduction parameter is determined as the target noise reduction parameter.
- the audio signal processing apparatus can divide the first audio signal into a low-frequency signal and a high-frequency signal, and respectively perform noise reduction processing with different noise reduction amounts on the low-frequency signal and the high-frequency signal, and, after the noise reduction processing
- the low-frequency signal and the high-frequency signal after the noise reduction process are synthesized and processed. Therefore, the voiced voice can be damaged in the voice signal after the noise reduction process, so as to avoid the reduction of the clarity of the voice signal after the noise reduction process. , in this way, the effect of noise reduction processing performed on the audio signal by the audio signal processing apparatus can be improved.
Abstract
La présente demande concerne un procédé et un appareil de traitement de signal sonore, ainsi qu'un dispositif électronique. Le procédé de traitement de signal sonore comprend les étapes suivantes : acquérir un signal basse fréquence dans un premier signal sonore, le signal basse fréquence étant un signal sonore dont la fréquence se situe dans une plage de fréquences prédéfinie, et le signal basse fréquence comprenant M points de fréquence; déterminer M valeurs de probabilité respectivement en fonction de valeurs d'énergie des M points de fréquence, chaque valeur de probabilité étant utilisée pour indiquer la probabilité qu'il y ait un signal vocal au point de fréquence correspondant; sur la base des M valeurs de probabilité, déterminer un paramètre de réduction de bruit cible, le paramètre de réduction de bruit cible étant utilisé pour représenter une quantité de réduction de bruit d'un dispositif électronique effectuant un traitement de réduction de bruit sur le signal sonore; et sur la base du paramètre de réduction de bruit cible, réaliser un traitement de réduction de bruit sur le signal basse fréquence.
