Equalization issue for 24/192 flac files

When I bring in a converted Pono flac file for editing (24 bit, 192 kHz), I can edit most of the waveform using Equalization… (the latest version of Audacity - 2.0.5), and even import XML equalization files that seem to work, but only above about 150-200 Hz. Below that point, I can edit the XML-imported EQ curve to cut low frequency peaks–and nothing changes in the resulting output tracks (using Ctrl-S to see the FR curves). If I save the XML file, exit Audacity, start-up Audacity again, load the saved XML file, it seems to clear the problem, but not entirely.

Is this a known bug?

This is odd behavior that I’ve not experienced on over 4000 audio tracks that I’ve remastered at 16b/44.1kHz (CD tracks) and even DVD-A tracks. Am I missing something?

Additionally, Audacity seems to be halving the sampling resolution of the output files on export (which I assume is a settings problem).


I suggest you use the current 2.1.0 version of Audacity supplied by us http://www.fosshub.com/Audacity.html and re-test.


In Audacity supplied by us, the export sample rate is set at Project Rate bottom left.

If you want a 24-bit depth FLAC export, press the Options… button in the Export Audio dialogue after selecting “FLAC Files”.


Thanks, I’ll try the latest version of Audacity (which I just discovered after posting changed on 30 March).

I’m hoping it will fix the EQ problem, but I’m not holding my breath. I’ll update my settings for export.

I bet you get a lot of chances to use the blanket statement “…update to the latest version…” when addressing bug reports. :wink:

What you described is not a known problem, but CTRL + S would by default save an Audacity project, which made me wonder about the authenticity of the version you had.

We can’t retro-fix old versions but if the problem occurs in 2.1.0 we can do something about it. Please attach the XML file in question if there is a problem in 2.1.0 and give us steps 1, 2, 3 to reproduce the issue.

Sorry - Alt-S. I use Alt-x (1-8, S) as a hot key so much for various effects that I’ve come to think of it as Ctrl-x.
