Then install it (though it should be installed by default almost everywhere). Personally, I use ffprobe for that purpose.

File indeed works just fine:

file 440.flac 440.flac: FLAC audio bitstream data, 24 bit, mono, 44.1 kHz, 1323000 samples

I don't think I ever installed this separately. It also resides in /usr/bin/, which is a good indication that it's standard, but no guarantee. Another indication is the fact that it's a universal binary (even with arm64 support). It would not be if it would be installed via something like brew:

file /usr/bin/file /usr/bin/file: Mach-O universal binary with 3 architectures: [x86_64:Mach-O 64-bit executable x86_64] [arm64:Mach-O 64-bit executable arm64] [arm64e:Mach-O 64-bit executable arm64e] /usr/bin/file (for architecture x86_64): Mach-O 64-bit executable x86_64 /usr/bin/file (for architecture arm64): Mach-O 64-bit executable arm64 /usr/bin/file (for architecture arm64e): Mach-O 64-bit executable arm64e

I use the free programme Fakin' the funk, which will give a thumbs up if the file matches the stated bitrate, and a thumbs down if it doesn't match it. It will also show a spectogram if you like. This spectogram shows the upper limits for various mp3 codecs.
It should be noted, however, that in the settings you would have to set it to measure aggressively to distinguish between 256 kbps mp3 and higher, and the programme does have difficulties properly detecting the bitrate of the Fraunhofer mp3 codec (used by Windows Media Player).
Otherwise, I'm very happy with this programme. I had an album as flac and found out that it was only 160 kbps mp3 :-/.

I'm looking for a quick way to check out some FLAC files to see if they are high res, Redbook level, or lower.

Is there any free software that can quickly check this on MacOS?

Thx.
Brew install ffmpeg
amd you get plenty of infos, man ffmpeg.
there is also a ffprobe cli that does it well.

Does anybody know what happened to this track ? It looks like a double mp3 compression first at 10 khz and later at 16 khz . Taken from a cd that is probably a cassette rip, but this still does not explain.

This program is a joke. It says the original file is "upsampled" and 24-bit FLAC files converted from mp3 are "clean".

Also, even my little toy program can detect issues in some MQA files, and this Lossless Audio Checker can't.

Excuse me but there are even research papers available for this software!!

Hydrogenude.io? Really?? These are real freaks!!!
Again. Try the files. Apart from hydrogenaud.io, the last link is from ASR, GoldeOne's MQA test files. Don't avoid the reality.

ffprobe (part of the ffmpeg suite) would be able to report the stated bit depth and sample rate. It's not going to do in depth checking and analysis though.
I gave up on audio checking tools some time back, only employing mp3val.exe to check mp3files for most errors that'd prevent play.
If I want to check the quality or compare, Ill load the files up into the DAW and use spectral analysis tools there.
