Wav to MP3 Conversion

I'm making a program in Delphi, which records the audio from vinyl records, then detects and separates the different tracks from each other. My problem is I can't convert the recorded wav files to mp3. I have tried to use LAME, but that gives me an mp3 file that plays to slow (eg. I start with a 1 min wav and it lands up as a 5 min mp3)

Please can you suggest source code or components with which I can convert wav files to mp3s.

You can enjoy your favorite music 5x times longer, that's awesome! No, seriously, LAME encoder works pretty fine (I know it, we are in relationship :-), I would suspect the way you are recording vinyls to wav. Have you heard them ? – TLama
LAME works very well. You are probably using it wrong. Without code we can't tell. – David Heffernan
Perhaps you're configuring the wrong sample rates? If you turn a 48KHz wav into a 8Khz mp3 without resampling, your result will play too slow. If you show some code, or upload your wav+mp3 somewhere, we can probably tell you what's going wrong. – Wouter van Nifterick
Thanks, I got the mp3 playing at more or less the right speed, but i did it through trial and error, is there a way to get the sample rate from the wav? – Grant
