MP3 plays too fast, slow or chipmunked


A good step thru of re-encoding mp3s with LAME at http://www.boutell.com/newfaq/creating/chipmunk.html

Seems odd that the answer is to re-encode the files. We know they play properly, isn't there a setting or some such that can be changed on the flash player side?

"These records don't play well on this gramophone... go re-press your whole record collection" :d

"These records don't play well on this gramophone... go re-press your whole record collection" - perhaps the gramophone was built poorly? Not saying Flash is built poorly at all, just the MP3 playback part ;)

@asyrazi,

Start with the readme [url=http://www.jeroenwijering.com/extras/readme.html]JW PLAYERS 3.9 README[/url], then look at the examples linked from the readme, and look through these forums for the many examples of a first, simple implementation.

If you run into a roadblock, post on these forums with your code or a link to your page and someone will help you overcome that obstacle. You will become an expert sooner than you think. :)

I just had an issue where adding an ID3v2 tag in Winamp caused the MP3 to play chipmunk style. Removing the tag made it play normal again. So I added the tag details using the Basic Info tab only (which automatically adds an ID3v2 tag), and everything seems fine.

My mp3s are playing fine in Firefox, Opera, and Safari, but in IE7 they are chipmunking. Is this a browser issue?

Possibly an Adobe Flash Player issue. Only the latest couple of versions 9,0,115,0 and 9,0,124,0 accept a wider range of audio encoding. Try updating the Adobe Flash Player if you don't have one of those versions.

I found this fix after a lot of googling. Change the extension of your AC3 filter to a unrecognizeable extension to see if this fixes it. It fixed mine. If it doesn't work for you then change the extension back.

Pass this along as it is a common problem that nobody knows how to fix, except you, now.

s1.addVariable("height","20");
s1.addVariable("autostart","true");

convert mp3 bitrate to slow as possible for older player like 128, just reconvert the song but change the bitrate setting.

I just started having this problem on my rig too. All sounds play more slowly and several octaves lower than than they should during normal playback. I've ripped mp3s using Audiograbber with LAME at 320k for many years and for at least 3 years on this rig, and this is the first time I've encountered this problem, so I don't think bitrate is the issue here. I suspect a dying sound card.

I'm using a Creative Sound Blaster X-Fi Platinum. Anyone else using a similar card?

It's also possible that some Creative s/w that came with the card is creating the problem. I was creating sound files using pitch shifters, chorus, and digital delays when the problem first occured, and I just so happened to have the pitch shifter set to produce frequencies several octaves lower than what was being input. As it turns out, the symptoms are pretty much what I was shooting for when tweeking my audio console settings to produce that effect. Hmmm...

@M!K3

from the [url=http://www.jeroenwijering.com/extras/readme.html]readme[/url]:

bc.. If you encounter too fast or too slow playback of MP3 files or if your progressbar is messed up, your MP3 files contains variable bitrate encoding. Flash isn't very good at handling these, it's best to stick to constant bitrate encoding. Also make sure to stick to a sampling frequency that is a multitude of 11.025kHz (48kHz, for example, also poses problems). The free [url=http://www.apple.com/itunes]iTunes software[/url] has a basic, decent MP3 encoder.

I too have a Creative SB X-Fi on a Gateway desktop that just stopped playing all sounds (including system sounds) through either headphones or speakers. All videos now play twice as fast as normal, including youtube vids, etc.
When I run through the control panel/sounds/ troubleshooting, it tells several things;
In the volume tab, all the settings are greyed out and my sound card is not listed (so in troubleshooting mode, I cannot click "advanced"as the instructions say to, because it is greyed out).
The SB shows up only in the hardware tab, and says it is not installed; when I tell Windows to search for it and install, it sees the card but I get this message "This device cannot start. (Code 10).
Any help greatly appreciated.

I am testing recording audio (actionscript myself, non jw-related) and I just want to tell you that the playback speed will be affected if recording bitrate is different.
When I set it up to 44khz then playback is fine, anything lower speeds up playback
The problem is I have not found a way to change it during playback because I have this option available only in sound recording objects ...
So my advice - check what are the settings of recording and playing audio (chipmunk/windows/flash)

Hi guys. Intruding here as I found this topic whilst searching for a solution to a similar problem with Audacity where some songs would play slow or fast when imported.

Just in case somebody finds this topic looking for a similar solution, here's what I've found:

Removing special characters from the tags (I used mp3tag). I'd remove anything that can be considered. Removing a $ fixed my problem.

Maybe it'll solve similar, Flash related problems too.

Hope this helps somebody.
