Where to download the wav file?

Same issue here. The audio file is seemingly corrupted, which sounds like Lord Vader.

@hupei1991 Where can I download the audio file?

hupei1991 commented 5 years ago

I didn't download the audio file. I just used the AudioRecorder with default setting, to record my own voice, saving as WAV file. Then I tried to convert it to AMR. Then the sound was corrupted.

Well, can you give me some infomation about the wav file. I think maybe something wrong with the audio file's detail information, such as bitstream, req_mode and etc. My E-mail is loktarlai#gmail.com. So can you send it to me? Thanks

My another project TSWechat is using the library. It works fine. Here it is: https://github.com/hilen/TSWeChat/blob/master/TSWeChat/Classes/Chat/ChatHelper/AudioRecordManager.swift#L96-L104

I agree with you concerning the header info of the audio file. Please spare me some time so that I can revert my code, and send the original and converted audio file to your email.
