Audio coding and decoding method and device and electronic equipment

The invention provides an audio coding and decoding method and device and electronic equipment. A specific implementation mode of the method comprises the following steps: acquiring a frame of audio data to be processed; based on a plurality of coding blocks, carrying out coding processing on the audio data; each coding block comprises a first convolutional neural network and a recurrent neural network; and performing feature quantization processing on a result after the coding processing to obtain target coding data of the audio data. According to the embodiment, the global feature obtained by encoding the audio feature can fully reflect the time sequence information of one frame of audio data, so that the audio encoding effect is improved. 本公开提供一种音频编码和解码方法、装置及电子设备，所述方法的一具体实施方式包括：获取待处理的一帧音频数据；基于多个编码块，对所述音频数据进行编码处理；每个所述编码块包括第一卷积神经网络和循环神经网络；对经过所述编码处理之后的结果进行特征量化处理，得到所述音频数据的目标编码数据。该实施方式对该音频特征进行编码处理得到的全局特征能够充分体现一帧音频数据的时序信息，从而提高了音频编码的效果。
