But of course, the old masters like Vivaldi back in the day may have been morons since they also used the more natural 432hz tuning. There´s a lot of serious research about frequencies and the response of organic life or the human psyche. I don not know about LaRouche that much, so I can´t say anything about him.īut for sure and I want to be honest in a respectful way: I don´t like the way you bring up the term “conspiracy theories” (which is one of the most used framing term in the media to keep the people in line) in the context of my pure technical question. The reasons I wanna do this is my very own business. I want you to know, I just wanted to discuss the technical issues of converting music with audacity. Like so many other con artists, LaRouche delighted in spreading conspiracy theories that were, and still are complete nonsense. But still, the 440hz tuning (which is just meant as a reference for all the other notes as well) was created intentionally as a standard and the A=440hz is the reference. Yes, I did try number one and two, but I guess I will stick with changing the tempo. Have you tried the other three ways of changing pitch:
With modern motor speed-control electronics, the correct speed can be maintained automatically so that’s not necessary but some DJs use the speed control as an “effect” or to match the musical key of two different songs they are mixing. There is a strobe and the idea was not to “alter” the speed but to accurately adjust it. I have an older turntable with a speed/pitch control.With chords and multiple instruments playing different notes the frequency content gets much more complex.Īlthough virtually all modern “western” music is tuned to A=440, the musical scale used for a song rarely contains all 12 notes and there is plenty of music with no A-notes. It’s the harmonics & overtones that make a trumpet sound different from a piano and it’s what makes different singers sound different when they are singing the same notes. A single note contains many harmonics and overtones. Normal music contains THOUSANDS of simultaneous frequencies that change moment-to-moment. If you wanted a trumpet tuned differently it would have to be designed & constructed to a different standard. But it takes a long time (and skill) to re-tune a piano and many instruments can’t be re-tuned. NTSC video is ~30FPS so the DVD conversion is done differently without changing the speed/pitch.īTW - Some instruments (like guitar) can be easily tuned to A=432. Or again, musicians trying to play in-tune have to correct the speed. (Of course playing time is also a few minutes faster than the original movie.) …Nobody really notices that or is bothered by it except some people check the playing time and they wonder of some scenes were cut-out. PAL DVDs are usually off-pitch because film is 24 frames-per-second and PAL video is 25 FPS and the audio/video is simply sped-up by 4%.
Usually nobody notices that except musicians trying to play-along in-tune with the recording. There are a FEW recordings that are “off pitch” or with the speed altered (intentionally or accidentally) so it doesn’t match any known tuning standard. When you change the speed, the pitch and speed are changed together by the same percentage, so yes it works with ALL music. So if the slight tempo change doesn’t bother you just change the speed.
It’s “cleaner” and you are much less likely to get side-effects. Right now I try the results from just changing the speed, but it may not work for any kind of music.Ĭhanging the speed is mathematically a LOT simpler (just like slowing-down a record player* or tape recorder).
