This article is just to introduce the whole process of making AAC audio files. It is only for reference. If you have a better method, you don’t need to use this method.

1. Search in the WeChat applet
语音朗读助手and click to open

2. After opening the applet, click

6. Select audio, click the setting button, enter the audio setting, configure the sampling rate as 44100, and click OK.
-
7. After the conversion is successful, an audio file ending in aac will be generated. At this time, the file you need has been converted into an audio file that can be used in our subsequent development.
-
8. Here take hiopenais as an example. If you want to use hiopenais to play audio, please copy the aac file generated in step 6 (modify the file name according to your needs) to the Ubuntu directory. Of course, you can also specify it as
code\hiopenais\sdk\hi3516dv300\osdrv\pub\rootfs_glibc\hiopenais\audiorootfs_glibc other directories.
