What is Reddit's opinion of Lossless Audio Checker?

From 3.5 billion Reddit comments

I assume you're mostly looking for detecting AAC or MP3 to FLAC transcodings. You're in luck -- a research group at a couple of French institutions published a paper on this in February and have released their tool, which works on Linux: http://losslessaudiochecker.com I've never tried it, so I don't know if it's available as open source or as a binary. I'd imagine the source is available though.

Most of the info lost in lossy conversion is over the audible range. That said, if you focus super hard, some tracks lose audible things. I personally can't even hear over 16.5kHz anyway but I still buy FLAC for archive purposes. A cool little experiment is to convert a FLAC to 320 MP3, use a program to subtract the difference, then listen to that subtracted filter. Afterwards, go back to the FLAC and MP3 and see if you have hear the missing parts in the FLAC but not the MP3. Quick tutorial for Adobe here. To make the experiment the most valid, you should use a FLAC you either ripped yourself or passes a lossy test like the one here. It is possible to get false positives but harder (maybe near impossible?) to get false negatives. I personally don't notice enough of a difference to justify the increase in cost and only got the HiFi version of Deezer to try out Sony 360 which was kinda meh.

Can you run lossless audio checker on your self-titled FLAC and tell me what the results are? Like half of the tracks on that album look like they are transcodes *on my end but I don't know if I just have a bad rip or if the production quality was just that low:

>I heard that you can't download flacs anymore on deezloader. But I still can download them.

Same here. If anyone can tell me where this is coming from, let me know.

Some people have this idea that you need to pay for Deezer just to pull FLAC files, but at least for me (which was not too long ago using Deemix), I can still pull FLAC files on a free account.

And for programs that you can use to check if a FLAC, I've personally used Spek. I think you're looking to see if the spectrogram fills the entire 22kHz. There's also Lossless Audio Checker, but I couldn't get it to work (Linux CLI version) on FLAC files pulled from Deezer. I also can't say if it's accurate or not.

I have a lot of flac format music I downloaded years ago. Just want to check if it's really high quality or someone just converted an mp3 to flac. Is there a good way to do that? I'm referring to solutions like this: http://losslessaudiochecker.com/

Has anyone else here experienced good and bad rips of the same album in the same bit rate? I've downloaded the same albums from two different sources, both flac but the quality seemed wildly different. Just recently I got a copy of Colour To The Moon by Allan Taylor and it sounded a bit shitty, like the mid-bass was muddy and the top end seemed pretty harsh. Downloaded it from a different source and it sounded much better. Both copies were flac, both were a similar size but there were noticeable differences in both sound and the waveform produced in Foobar. I checked both in Lossless Audio Checker and both came up clean of upsampling or upscaling.
