I was forced to give up my beloved Audacity which I had used for years, after moving from WFW311-W95-98SE over to Windows 7 [and I never found out why]! Now, there are free and fee alternatives out there, I went with Cyberlink's WaveEditor Express and later with Premium. I'm certainly glad I did! WE definitely does what I need it to do: allow full editing, and, I discovered, one can even "convert" a practice MP3 [which had right-speaker music and left-speaker vocals] into a mono-music only or mono-voice only. I do not know what SoundTap is.
