Lossy or 32Khz DAT

[range_hood]

could you please provide a 10 secs. sound sample?

[ssamadhi97]

yea, this stuff is 32kHz sourced indeed

take a look at these

and note how the spectrum close above 16kHz (fs/2) looks like a flipped image of the spectrum close below 16kHz. that's a typical sign of upsampling (whose presence depends on the resampling implementation used - it might be more or less pronounced in other 32kHz sourced recordings).

I went back to the original DAT in question, and yes indeed, this was recorded at 32k. I dont know what to say-I am so embarrassed. My apologies to Thornhill, who seeded this for me, and anyone else offended by the 32k recording.

Just curious. So is my original assessment of the recording that I've asked in the first place is indeed 32Khz DAT as well?

32k aint exactly a shit in the eardrums. its a quite welcome break from all the damn mp3 sourced and minidisc b.s. ive gotten in the past from other sources, and for anyone who recieved this recording in the seed, im sure they can attest.

This is great info. Thanks ssamadhi97.

np.

I should have some more blatant examples somewhere, "for great illustration". Stuff like 32kHz DAT upsampled to 48kHz and back to 44.1kHz on the fly during transfer through a SBLive!, for example. (Thanks a lot, Creative. Please die.) I shall dig for some good pics once I'm back home.

I've got 2 recordings where the source more or less swears its never on mp3, but rather on 32KHz DAT. Unlike the waveform posted earlier in another thread, its rather different. And at 16Khz, there is mirror image flip at that point to signify upsampling.

I'll attached images of the SA of the 1st of 2 recodings...

The attachments here will be the 2nd of the 2 recordings.
