Identical output for DTW and CC in Acoustic similarity #637

Open witteerik opened 7 years ago

witteerik commented 7 years ago

Hi, I've been trying to calculate acoustic similarity for a bunch of Swedish phonemes. Testing the various parameters in the Acoustic similarity dialog box, I've noticed that I get exactly the same result for dynamic time warping and cross-correlation. I guess this shouldn't be the case!? I've also tried it with a little longer sounds containing various noises and silent parts, and I still get identical output between DTW and CC. I've tested it on the available Mac and Windows releases (except for the latest windows release, which seem to crash when starting an acoustic similarity calculation).

(The sound files I've used are mono 48kHz 32bit float wave files.)

Anyone else noticed this, and is there a way around it?

^ Thanks for the comment! I've forwarded this to the programmer who designed the Acoustic Similarity module, but he's not officially still working on this project, so the response may be slightly delayed.
