Customers running Windows 7 may experience audio corruption of extremely short MP3 files when they’re played in Windows Media Player 12, warned Microsoft “In WMP12 on Win7, if you attempt to playback MP3 audio files that’re less than 1 second in length you may hear a slight popping noise or stuttering of the audio. This can be especially noticeable when using audio files that only contain vocals or the spoken word,” the software giant stated. In some cases app may attempt initialization of the audio outputs but the process may not’ve been completed before playback of the audio file begins. This can lead to an unwanted stuttering, subsequent attempts to play back the audio file may work correctly. “There’s currently no direct workaround available for this problem. If however it’s possible to modify MP3’s by adding a second of silence before and after the audio this should allow for audio to be correctly heard. Developers can also use other playback methods that aren’t affected by this issue,” Microsoft stated in KB2022133.
