When I open 5.1 flac or wav files the rears(bottom channels on audacity) are uneven. Audacity is making one louder than other when they should be identical.
what is the issue? why? This is happening every time I open a file.
Audacity is making one louder than other
I’m pretty sure it’s not Audacity…
This is happening every time I open a file.
If this is happening on multiple files, I’d guess you are confused about which channel is which.
P.S.
I found a file called [u]surround51.flac[/u] and all of the channels have approximately equal volume except for the LFE channel.
Nope I am not confused at all.
I have been mixing music and editing surround files for years. Audacity is opening files with bottom(rears) at unequal levels.
Perhaps those channels are at unequal levels in the file.
Why do you think they should be identical?
Nope. The channels are exact, yet audacity is opening them at different levels.
What does that mean?
What is the file that you are using?
Any 5.1 file flac or wav I open has the reas uneven. Rears would be bottom 2 files in Audacity. It opens 6 mono.
Try this file:
The bottom two tracks should be identical.
YEP they are.
Maybe it is dvd audio extractor ripping them uneven?
Perhaps. Or maybe it’s allocating channels in a non-standard order?
Assuming the sound quality is OK, you can adjust the volume with the Amplify effect, the Normalize effect, or the Loudness Normalization effect. You can select one channel at a time or normalize everything (or the selected channels) together.

We know it’s not Audacity… It’s pretty much impossible to “accidentally” change the volume of a WAV or FLAC file.
It might be possible for something to go wrong when decoding one of the more-compressed formats but I’ve never heard of that happening. There is some playback-volume metadata in Dolby AC3 files and sometimes that gets ignored but it’s for the whole file, not channel-by-channel.
