I would love to tell you that! I encourage everyone to do this with some of their favorite songs...
1. If you don't have a guitar, you are going to have to test by feeling, though you can be reasonably sure that most songs ARE in 440 hz, and a pitch
shift of +4 WILL fix it. Bare with me. If a song never feels/sounds as pleasing as you'd hope after the shift, it may not have been exactly 440 hz
2. If you do have a guitar, tune it to 444 Hz, or to the song "Comfy in Nautica" by Panda Bear (look on Grooveshark or YouYube). It's one chord for
four minutes or so, so it's easy to tune to.
3. Download Audacity at download.cnet.com...
. You may need to download LAME mp3 Encoder if you
want to export your transpositions into 444 hz as mp3s.
4. Open an mp3 in question. If you have a guitar, test whether it's already in tune with your 444 hz-tuned guitar. Highly unlikely, but a good
control nonetheless. Go to effects > pitch shift > type in 440 to the first frequency box and 444. Audacity will take care of the rest. Don't worry
about specifying notes at the top, you just need to give the frequencies.
5. Once the pitch shift is complete, is it in tune? For those without a guitar, does it FEEL better? Yes it's subjective, but listen to the whole
song. Did you find yourself WANTING to listen to the whole song? Did it make you any happier than usual to hear it? Any increased emotional
response? To those with a guitar -- if it's perfectly in tune after a shift, you know it was tuned down 4 hz intentionally. If not, some songs are
not tuned right to concert pitch. This method though, proved accurate and effective for 95% of the fourty or so mp3s I transposed. Therefore, even
without a guitar, you can be reasonably confident that most songs are 440 hz and a +4 pitch shift will make them tuned to 444 hz / 528 hz.
6. If you have LAME mp3 encoder you can export the transposed mp3 as a new mp3. FIRST in edit > preferences > file formats, make sure bit rate is at
least 256 if not 320. This just ensures your new mp3 doesn't lose any discernible sound quality.
