You bought a 24-bit download. Is it real?

The file says 24-bit/96kHz, the receipt says hi-res, and both are telling the truth about the container. Neither says anything about where the audio inside it came from — and that is the part you actually paid extra for.

Three different things get sold as "hi-res"

Before assuming bad faith, it helps to separate the cases, because they are not equally suspicious.

1. A genuine high-resolution transfer

The master was captured or transferred at high resolution and the file carries information a CD could not. This is what you are paying for and it is common enough.

2. An upsampled standard-resolution master

A 44.1kHz master resampled to 96kHz. The file is honestly 96kHz; the information is not. Resampling never adds detail that was not captured — it only describes the same audio with more numbers.

3. A high-resolution transfer of an old analogue master

Here the numbers are real and the content above 20kHz is still thin, because the tape, the microphones or the original mixdown never held much up there. This file is not a fraud. It is an honest capture of something that was recorded in 1968.

Where the problem usually comes from

It is worth being fair about this. A store sells what the label delivers, and the label delivers what the archive hands over. When a release turns out to be upsampled, the cause is more often a provenance gap somewhere up the chain than a shop deciding to defraud anyone. Stores that specialise in hi-res depend on their reputation for provenance, which is exactly why a specific, measured complaint tends to get a real answer.

Artist-upload platforms are a different shape of the same issue: what you get is the file the artist uploaded. Plenty of independent releases are mastered from high-resolution sources; plenty are bounced from a project that was only ever 44.1kHz. Neither fact is hidden — it just is not printed anywhere.

How to check what you bought

1. Look at where the top end stops relative to what the file claims. A 96kHz file can carry content to 48kHz. If nothing is happening above 20kHz at all, the extra sample rate is doing no work.
2. Check whether the edge moves. Real music wanders at the top. A mechanical, unchanging ceiling from first second to last is applied by an encoder, not performed by a band.
3. Compare against a release you trust from the same era and genre. This is the step most people skip and it is the most informative one — it tells you what "normal" looks like for that kind of recording.
4. Check the bit depth claim too. A file can be 24-bit and still have a noise floor that betrays a 16-bit origin.
5. Note what you measured. "The spectrum stops flat at 19.8kHz across the whole album" is something support can act on. "It sounds off" is not.

What to do if it looks upsampled

• Contact the store with specifics — release, track, what you measured. Most hi-res retailers have handled this before and some maintain provenance documentation for exactly this reason.
• Do not assume fraud in public. Case 3 above exists, and accusing a label of faking an archival transfer that is simply old is a good way to be wrong loudly.
• Keep the file until it is resolved. It is your evidence.
• Do not re-encode it "to fix it". Converting an upsampled file to a larger format produces a larger upsampled file.

Does it matter if you cannot hear it?

Honest answer: for listening, often not. A well-made 44.1kHz master can sound better than a careless high-resolution one, and most playback chains and most rooms will not reveal the difference anyway. What you are buying with hi-res is a claim about provenance — that this file came from a better source than the CD did. When the claim is wrong, the thing you paid for is missing, whether or not your ears can file the complaint themselves.
