Hope this is an appropriate place to park this question. I've always struggled when dealing with a source that doesn't play back at the correct pitch. Anyone with a good ear for this sort of thing want to take a stab at what correction factor I need so this song runs at the correct speed/pitch?

Sample 1 is a reference track that plays back at the correct speed/pitch. Sample 2 is a different performance of the same song that is obviously fast. The song is in a strange tuning, DADGAD and the tonic note is D.

Try the Soundtouch plugin in Foobar 2000 and your ears to manually correct pitch/tempo in the second file The result can be saved to wav or anything else...

Thanks for the suggestion. I have the tools to fix it, but am unsure how much of a correction to make. Looking for someone with more experience or scientific methods to offer a % correction.

Load them into cooledit, use frequency analysis. It computes dominant frequency and musical note.

"The right status area directly underneath the graph displays the waveform’s dominant frequency for the left and right channels measured at the cursor's position. It also shows, in parentheses, each channel’s musical equivalent note number and positive/negative cents.

The dominant frequency is not simply the frequency with the highest amplitude. Harmonics are taken into account when determining the dominant frequency."
