Re: [Flashcoders] Chipmunk-sounding MP3s?

2006-06-24 Thread Josh Santangelo
Nevermind, found it myself. As it turns out, the bitrate doesn't  
matter so much as the sample rate. Flash only supports 11, 22, and  
44khz, and seems to freak out otherwise.

play fine in QuickTime Player, but when loaded into Flash (via the  
Sound object) play back at super-speed and pitched up.


I was told at some point that Flash can only handle certain  
encodings and bitrates of MP3s, but 16k/mono is one of the options  
for exporting, so I would expect that it would be able to handle  
loading them as well. Is there a list of what bitrates are  
supported somewhere? Google isn't giving me any love.

I don't think it's the bitrates, but the hertz.

Hello,
   
  I had the same problem this helped clear things up.
   
  http://www.jeroenwijering.com/?thread=High_Speed_Play
   
  you have to use a sample rate of 44100Hz, I've used 22050Hz with no problems, 
along with a constant bit rate (CBR) and that will take care of the chipmunks 
problem.
   
  Perhaps you are using a variable bitrate on compression.
   
  Hope this helps.
