Yes, if I'm understanding your question. BIAB 2015 has a much improved means for doing this. Open an mp3 (File/Open Audio), hit play. Should play normally. Then adjust speed with "%" (with no pitch change) to the right of Tempo. Quality seems pretty good to my. Then, of course, if you change the key in BIAB, the audio changes appropriately.

I have used SlowDowner. Good quality but limited and bad UI. Then went to Transcribe. Really good program. But now with it so easy in BIAB, and it handles audio, midi, and video at once, what could be better.

Now, if you want to align BIAB tempo (and measure advance) with the audio, look into BIAB,s Audio Chord Wizard. Good luck.
