Tuning MP3 tracks

Hi

I’ve just built myself a Low Tech whistle set with two heads (sweet/quiet and loud/breathy) and four bodies (C,D,D+,Eb+) from CPVC hot water pipe. I went to great pains to make sure they are in tune, and they are somewhat tuneable, but not more than 3-4 millimeters up or down because the pipe joints I used to join the heads to the bodies are conical rather than cylindrical inside. (I’ll be looking for a new design for the next batch.)

I’ve been trying (again) to play along to some recordings I have in MP3 format. While I find that most Whistle only recordings I’ve downloaded are pretty much in tune, the same can not be said for some of the stuff I’ve ripped from CD’s.

I’ve heard of the Amazing Slowdowner software which can slow down an MP3 track without altering the pitch. I was wondering, is there anything out there that can alter the pitch without altering the tempo? I’d like not only to be able to do it in real time during playback, but also to be able to save the altered file for playback on my MP3 player. Even better (in some cases) would be to be able to alter the pitch AND slow down, but independently of course, not like changing the speed of an LP (remember those?)

Freeware or very cheap shareware would fit nicely with my budget.

I think Audacity does what you’re talking about. And it’s free! :smiley:

I have the Amazing Slow Downer program. I use it A LOT. There is an adjustment for pitch and its separate from the speed. It’s not cheap, but I rarely buy software and I think it’s well worth the price. Good luck!

Audacity is useful for so many different things, almost every musician I know–at least those without a Mac–has it and swears by it. It’s a good, solid, FREE piece of software. I use mine for burning Vinyl to digital formats, but it does lots more than I ever do. The worst thing I know is that some stuff isn’t easy to figure out how it works, but that’s true of a lot of open source software. It took me a while to learn how to mark up one long recording into tracks for batch conversion, for instance.

I also have and use a registered copy of the amazing slowdowner that I use for just that. I paid $40 years ago for it. You can (or could) get the freeware version which does everything the registered version does, but only plays the first two trax of a CD, so the “burn your own” workaraound works, if it’s really important.

I find transcribe! from seventhstring.com invaluable. It can change speed and pitch and identify notes. Audacity is great for recording multy tracks too.
