32kHz DAT

Here's some stuff from a DAT recorded at 32kHz. Maybe someone will find it useful for comparison purposes.

Re: 32kHz DAT

the tricky problem with 32kHz DAT sources is that their spectrum strongly depends on the method used for resampling to 44.1kHz

Interesting.

EAC would only open a 44.1kHz file.

I changed the sample rate using Wavelab.

correct, that was over here:
http://www.thetradersden.org/forums/...ead.php?t=1331

the screenshots in the thread tell the whole story. Since then, whenever I see sa or fa from EAC I don't trust it at all. Try giving it a run in AnalFreq, I think this link is still working:

Re: 32kHz DAT

AnalFreq is the best program for this, because it can capture averages over a large span. If someone has mp3ed or tried to apply too much noise reduction to some audio, it becomes apparent pretty quickly.

same with forge you can select the entire file for analysis if youd like

i prefer the waves paz its analysis is based on human hearing

Realtime analyzer based on our hearing, shows 52 or 68 bands, with RMS, peak, weighting, variable integration time, and much more. Built on the math that the ear uses...See what you've been hearing.
