Audio cleaning Lab 12

I have cleaned and processed a 60 minute music cassette from a radio programme 20 years old.

First I split it up in music and speech.

I only processed music. the rest was cleaned.

I listened to it in my computer and it was fantastic.

I burned in WAV - format it to be used in a local radio station.

But the result was a disaster. 

I could only hear som cracking from the CD.

Is it possible tp use a lower burning speed?

The lowest possible burning speed is 10X.
