Wrong duration HTML5 audio on mobile browsers, works fine on regular browsers (m4a file)

I am using Savedeo APIs to get to youtube audio files and trying to play the audio on a browser.

When I try to play an audio only file (.m4a) on regular browser, everything works fine. But, when I test it on a mobile browser on my iphone (safari and chrome), the audio file's duration is doubled. Basically after the end of the audio, there is a padding added.

Why is this happening? Is there any work around for this. If you need more info, will be happy to provide.

Thanks

I ran into this issue with a MP3 with a sample rate of 44100 Hz and a 128kb bitrate. The solution is to change the sample rate with ffmpeg:

ffmpeg -i your.mp3 -ar 22050 your_fixed.mp3

You can retrieve critical information about an MP3 by using ffprobe:

ffprobe your.mp3

iTunes also reports the wrong duration when calculating the duration with the actual MP3 file. That's embarrassing since you would expect iTunes to get something like that correct. This indicates a bug exists in some library that Apple uses for MP3 duration calculations.
