Hi,

Actually I have simple .mp3 files in my website folder.. And I am using HTML5 Audio tag for playing those .mp3's. Now when a user selects a particular .mp3 file and selects its playback speed accordingly..and when he clicks save button.the song/.mp3 should be saved in a separate folder with the playback speed he has selected ..

I am stuck up in setting the playback speed for the .mp3 file..and saving it.

Please help me.

thanks & regards,

Playback is one thing, download is an other.
Setting playback rate on the browser will change nothing on the server.
So, if you want to let user download the file with altered speed, you have to make server side code to do it for the user, and send the modified file as attachment to download.
