RB cannot change the tempo of a wav file once it has been made.

There should be a message to that effect when you try to change the wav file tempo.

The only way to change the tempo of wav file safely is on RealTracks, but you must first erase the existing RealTrack(s), change the Tempo and then regenerate the RealTracks at that tempo setting.

Don't overlook the Tempo (BPM) range of the RealTracks in use. Typically we can go about 20 BPM slower and about 10 BPM faster than the tempo listed for the specific RealTrack before digital artifacts and other things start to happen due to the stretching.

Of course, if you have all MIDI tracks, you can change the BPM at will and get instant response.
