Unusual 48 kHz sampling rate

#3Alpha Flight 19702020-10-29 19:43

What exactly does this mean for the data of the file and the quality of the sound?

#4Anonymous2020-10-29 20:57

Probably unaudible. But if the source was regular mp3 @ 44,1 kHz purchased in a WEB store (which is most likely cuz it costs less and for most people 320 kbps mp3 got acceptable file size for almost the same as lossless quality) then it means a guaranteed lossy mp3-->mp3 reencode + upsampling artifacts. If the source was lossless @ 44,1 kHz then it's just about generic audio upsampling artifacts that could be even less impactful compared to lossless-->mp3 conversion losses

Oh, remembered 1 more option that involves paying even less money: re-encoding to mp3 from Spotify Premium's high-bitrate ogg/aac stream or m4a/aac tracks purchased in iTunes/Apple Music.
Which is tbh more likely because unless someone intentionally wants to screw free content users I don't see reason to bother with any kind of extra operations (only fixing tags maybe) to share an mp3 track if someone already got mp3 at hand that was encoded by/downloaded from a usual WEB shop

Thanks for the information. Can I know if a file is that way by looking at the spectrogram and if, how?

If all id3 tags are wiped and there's no Lame Tag (created only if it was encoded exactly by lame tool/exe, not ffmpeg or something else) with technical info (including sampling rate of the source file) I'm afraid you can only guess and either trust or not trust the source you got the file from. High-bitrate AAC VBR mimics lossless spectrum's visual so good that it's easy to confuse it even with proper/original WAV/FLAC, not to mention telling the difference of AAC-->MP3 vs. WAV-->MP3 encodes with same mp3 encoder version/settings used :(
Afaik, no (non-exotic) shop encodes/sells mp3 with Lame 3.100; 48 kHz lossless source is possible but is still quite rare (at least for hardcore/hardstyle genres) + only label official sites'/bandcamp/hardtunes/hardstyle.com shops can accept from producers/offer to customers this kind of "bonus" quality.
So it's up to you to decide if it's ok to help spreading around this kind of weird, unknown-sourced 48 kHz mp3s (they seem to show up way too often than you can suggest someone's buying lossless) - ofc it's better than nothing but it kinda lessens the chances of proper version to ever show up because most people don't know or care about all these technical nuances and'll just consider the release complete/issue closed if there's no obvious upscale

It looks like Spotify rip, which is possible in some ways, using Spotify premium. People report some songs they got from Spotify has a sampling rate 48kHz and some 44,1kHz:

https://community.spotify.com/t5/Other-Partners-Web-Player-etc/Spotify-Sample-Rate-Please-Help/td-p/704589
https://github.com/jwallet/spy-spotify/issues/77
So, atm we can consider web ripped tracks with a 48kHz sampling rate as Spotify rips, according to Occam's razor principle.

aGGyunit bothered to buy even iTunes' version (it's also AAC, just not in Spotify's .ogg container, but .m4a) and by sampling rate and freqs' cut (begins at ~18,5 kHz) it seems to be based on the lossless version he generously shared here (which should have filled the request btw). While 48 kHz sampling version seems to be based on some different/more freqs' "rich" lossless version of the track since its freqs' cut starts at ~20 kHz, i.e. default/proper one for 320 kbps mp3.
Maybe actually 48 kHz was the track's initial/original sampling rate at the stage when the producer completed it in the studio, then it got sort of early/"prematurely" published with this sampling rate at Spotify only and then it got downsampled to 44,1 kHz in such special way, resulting in "not-quite-lossless" spectrum, for all other WEB shops/streaming platforms. Weird

Grabbed the .WAV from Hardstyle.com ... and spectrum looks weird.
Encoded wav to MP3 and it looks like an upscaled file (reports as 256kbps)

Grabbed a copy on iTunes, similar spectrum.

Here's my FLAC (.WAV -> FLAC) from Hardstyle:

Here's 2 MP3s to test your iTunes re-code theory:
1 is from HS (WAV -> MP3)
the other one is from iTunes m4a->WAV->MP3
both encoded with LAME v3.100.1, identical settings.
both look like 256kbps upscales in spek/FakinTheFunk

Don't feel like paying a 3rd time to get the WAV from Junodownload ...
