SoundManager + FFMPEG causing loud popping sound when streaming MP3s?

Question

Hi there,

I built an application that plays both uploaded original mp3 files, and copies that have been converted with FFMPEG. I am finding that in some cases the FFMPEG files have a horrible popping/clicking/screeching sound for a split second at startup (hear below). But when I analyze the file in an audio editor there is nothing there, so it seems to be either the browser or soundManager reacting badly to something in that file. Wondering if there is any way I can fix this either by adjusting FFMPEG settings, soundManager settings, or..... Any suggestions?

I've uploaded the offending sound in the link below (before the music starts playing).

Thanks for your help!

Screeching/clicking at the beginning often points to a badly formed mp3 file. (There are a lot of them in the wild.)

Try checking both the original and converted files with mp3check -e -B

If you get errors, adding mp3check --cut-junk-start to your pipline should work.
