Description
Translated fromChinese技术领域technical field
本发明属于通信领域，尤其涉及一种安卓系统的音频处理方法及智能终端。The invention belongs to the communication field, and in particular relates to an audio processing method of an Android system and an intelligent terminal.
背景技术Background technique
目前安卓(android)系统的设备在进行音频处理时，尤其是回放音乐时仅支持一种音频的采样率，因此android系统在回放音乐时，先将声音数据源送到android混音系统进行统一采样率处理，处理后的声音数据源输出给声卡，这个处理的过程会造成声音数据源的损失，最终被声卡还原的声音失真会变大，音质变差。At present, Android system devices only support one audio sampling rate when performing audio processing, especially when playing back music. Therefore, when playing back music, the Android system first sends the sound data source to the Android mixing system for unified sampling. Rate processing, the processed sound data source is output to the sound card, this processing process will cause the loss of the sound data source, and the final sound restored by the sound card will be distorted and the sound quality will deteriorate.
