Abstract
(EN)
An audio data recovery method and apparatus and a Bluetooth device. The method comprises: dividing audio data into a first frequency component and a second frequency component in a frequency domain; for the second frequency component, employing a second data recovery technique to recover audio data; and for the first frequency component, employing a first data recovery technique less complex than the second data recovery technique to recover audio data.
(FR)
L'invention concerne un procédé et un appareil de récupération de données audio et un appareil Bluetooth. Le procédé consiste à : diviser des données audio en une première composante de fréquence et une seconde composante de fréquence dans un domaine de fréquence; pour la seconde composante de fréquence, utiliser une seconde technique de récupération de données pour récupérer des données audio; et pour la première composante de fréquence, utiliser une première technique de récupération de données moins complexe que la seconde technique de récupération de données pour récupérer des données audio.
(ZH)
音频数据恢复方法、装置及蓝牙设备,包括:在频域上将音频数据分为第一频域分量和第二频域分量,对第二频域分量采用第二数据恢复方法来恢复音频数据,对于第一频域分量,采用复杂度低于所述第二数据恢复的第一数据恢复方法来恢复音频数据。
