Streaming audio files are playing fast,help please!

[postman56]

When I'm using bouncing out a file in PT 5.3 mp3 internal convertor to produce a mp3 for streaming, they are playing back at proper
speed everywhere.
It's only when my customer uploads them onto their server via lpswitch software and puts them on their site to play via streaming audio,it then plays like a "chipmunk" comes into play.
Is there some setting's I'm over looking,for i have been compressing down to 64 kbps stereo
mp3.files.
Any suggestions,your help is appreciated.

If they're playing okay everywhere but on the clients server, that strongly suggests a problem with their server. But obvious question... Is your samplerate matching what they use? Do they have problems with other MP3's? Finally you could try LameBrain to encode your MP3's as a test. (It's free and very useful for batch conversion)
