Thank you!
I'm finding the levels are significantly different. Beyond mere peak issues that can be easily fixed, one of the files appears to have been compressed. Maybe due to overs?
RMS
avg level peak gain
-18.8208dBFS -0.1354dBFS 6.8208dB lhb1.wav
-16.3950dBFS -4.4382dBFS 4.3950dB lhb2.wav
If everything had gone right, I should be able to bring both samples up to 0 dBFS and have the avg RMS levels be very close. But if I bring both of these peak levels up to 0dBFS, sample 2 will be around -12 RMS AVG, vs -18 for sample 1. That is a huge difference in loudness.
I tried matching the RMS levels at -16, but the files still didn't sound close in terms of levels.
Also, the files are out of sync by about 4 or 6 seconds. That makes it hard to compare specific passages.
I may look at the files more, but I don't think these files can be made equivalent for comparison.
