A lot of DAWs have the same capability to change tempo on tracks now without impacting pitch. In Ableton it’s called warp, in Logic they call it flex time, think Reaper calls it stretch time or something like that…I am sure all the others have it now. I have transcribe too…you can get ideas of the notes played with the functionality in there if you really get stuck. Developing your ear, especially intervals, is what really helps…
I use Transcibe! for all my transcriptions and love it. I have tried other things, but always come back to Transcribe!
If anyone is interested, this is a great tutorial that I still refer to occasionally.
