File can not play normally in Android version

I have some old mp3 files.
These file can play normally in Windows. And encoding to any file type, foobar play sound all OK.

But if I use Android foobar to play. It sounds only click. Any encoding do not solve the problem.

How should I do to make Android foobar play these music sound normally? Here is one of them~

As Peter said, it's a bug in the Android (and likely also iOS and WinPhone) apps, the only thing you can do is wait for an updated version to hit.

This appears to be isolated to 64-bit ARM code, iOS has it too (confirmed), WInPhone does not.

It will be addressed shortly.

ARM 32bit Android also have this problem. All my 32/64bit Android devices can not play it.

OK, my reply was a bit too early, as I was confused by the very strange symptoms that it produced.

This file simply cannot be helped. It seemed like a bug in the MP3 decoder, but it is not.

This file turns into noise when downmixed to mono - which is what happens on most phone speakers. It does sound good only on headphones. It looks like a case of badly done recording and possibly bugged MP3 encoder. As if one of the channels was a phase-inverted copy of the other, with extra mutilation done by lossy encoding.

You can recreate this issue by playing it in classic fb2k and enabling 'downmix to mono' DSP.

In order to produce a playable version of this song, I recommend using an audio editor and extracting one of the channels - left or right - into a mono file. Or inverting phase on one of the channels.

[edit] amended suggestion how to fix the file

It's definitely and completly out of phase:



This will obviously lead to problems when downmixing to mono.
