wav --> amr

[jieatgstdev]

1.3M wav --> 127kb amr
1.3M wav time is 20s, However, transcoding amr format audio became 1m20s.
why?

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]

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.
