FLAC / Re: Spotify's FLAC is not lossless?

Brand new Lossless Audio Checker 2.0.7 reports: Upscaled.
Perhaps that is because the spotify.flac file is a 16-bit file packed in a 24-bit file with 8 wasted bits (like Porcus mentioned as possible). It is thus 'upscaled' in the sense that 8 bits of padding were added.

I can't say much about whether the source of this file has been lossy at some point. My usual test is inverting the right channel and mixing it with the left channel. If I do that with both files, I can hear something that sounds like compression artifacts in the opus file but not in the spotify file (ABX'ing isn't possible here, as I can't prove I do not hear something with it). Perhaps you should try yourself?

How did you cut the FLAC file? I'm curious which encoder is used by Spotify.

AFAIK Lossless Audio Checker doesn't care about the bitness, "upscaled" means something was compressed (e.g. mp3 codecs tend to cut off around 16KHz) and then "upscaled" to fill the missing spectrum.

As for cutting I used ffmpeg -i source.flac -ss 02:00 -to 2:29.5 -c:a copy -output.flac

General Audio / Re: Popularity Of Players According To Google Trends - All Down
Last post by birdie -
Yeah, nowadays people in general use PCs less and less. PCs are difficult to work with, they need maintenance, lengthy updates, etc. etc. etc. Your smartphone or tablet on the other hand is instantly available and works uninterruptedly.

Secondly, most people don't actually care what they listen to, they just enable whatever crap youtube or spotify throws at them. Keeping your music organized on your PC is tedious while online you can just click "like" and that's it.

I'd migrated to some streaming service a long time ago but none of them have all the music I like (some 5500 tracks at the moment).

3rd Party Plugins - (fb2k) / Re: iPod manager

Hello, so these are files that came from all over the place. I honestly don't even remember at this point. They are quite old. The below is a screenshot of the mediainfo specs of one of the files that is effected. I believe it should have all encoding information listed. I figured that the error just meant that for whatever reason, the file is lacking gapless data, however the error message specifically says "file may be corrupt" at the end of the full error message, I so I wanted to make sure.

Also, what is the best way for me to send you a sample file?

General Audio / Re: What's happening with "Dynamic Range DB"?

Unless you accidentally introduce clipping, which would be terrible of course, why would anyone want it?
Well...  Sometimes Loudness War recordings ARE intentionally clipped!    A couple of dB of clipping isn't necessarily audible, especially if you don't have the unclipped original to A/B compare.   And it could be just a short section that's clipped but that's unlikely because if somebody is doing that intentionally it's probably already compressed & limited to death.    And, a little (or a lot of) distortion can give the impression of more loudness and "intensity" and it could be a good thing if your goal is winning the loudness war. ;)

And I'm actually interested in (hopefully lack of) that kind of distortion that happens with extreme limiter usage, but not really interested in the loudness range.
If you want to experiment Audacity has compressor, limiter, and distortion effects.    But the limiter is VERY GOOD and with the hard & soft limiting settings it uses look-ahead so it won't actually distort the wave shape.  There are hard & soft clipping options that are more-like a traditional real-time analog limiter where you can't have look-ahead.
