Adding an ID3 tag in Winamp causes Flash Player to chipmunk MP3s · Thursday May 15, 2008 by Rudolf Vavruch
I just created an MP3 that when played through the Flash Player gets sped up, causing everything to sound high and squeaky—the “chipmunk effect”.
At first I checked that the sample rate was a multiple of 11.025 kHz and I reencoded at a constant bitrate—as recommended on the JW FLV Media Player site, which seemed to solve the problem until I added the ID3 tag and tested again—the “chipmunk effect” was back.
If I removed the tag the MP3 played fine again.
I was using Winamp to add the tags and I remembered that last time I did it I had used the Basic Info tab first (which automatically adds a ID3v2 tag). So first I added all the info on the Basic Info tab and then switched to the ID3v2 to fill in the rest.
It works fine. The problem only seemed to appear if I filled in the ID3v2 tab first.
