The whole time I was giving more attention to the sparkling playhead than the content of the video. My first thought was that this would be some sort of after-fx. But hey, this is Reaper, so it might be a thing a swell. Anyway: saw the video twice! Great content, as always!
This works perfectly with those tracks which have a constant tempo. The big pain kicks in when you have tracks with a fluctuating tempo, where, for instance, two bars are at 150 BPM, and then the next 2-3 bars are at 153, and then the next 2 bars are at 151 BPM, and so on and so forth :).
My free JSFX Tap Tempo figure a nice tap tempo calculation algorithm, using linear deviation as an accuracy indicator, midi input support etc. Can be nice for fixed tempo. (that ending is epic!)
So you were using rap vocals, which tend to fit over melodies fairly easily. What about a video where you take accapela sung vocals - and have to determine the key as well as the tempo?
This would be really helpful for people building productions out from vocal stems and needing to compose custom chord progressions and melodies underneath.
Obviously, this dips a little into music theory, but if anyone can pull this off in a clear and accessible way, it's surely you.
Thanks, Kenny. Do you think this would work for trying to figure out the tempo of some pieces of relaxation music? Quite often I think that genre seems to be not following a tempo at all, because there are only a few instances of a downbeat that I can detect, when a new section of music starts. But there seems to be no discernible tempo within those sections. Any suggestions?
I don't think this exists yet, but let say you wanted to put a symphonic piece to a metronome. Is there some way without manually pulling/stretching/reducing the music to fit your ideal BPM?
This undoubtedly works best on network that was produced with constant tempo. I wonder how Reaper handles tempo variations. Is there a step in the tempo at the next marker or can the tempo map be made to ramp the tempo? Asking for a friend 😉
