Scientific Discussion / Re: Help me understand why sound is one dimensional

Ok, to be more specific: a short-time Fourier transform, as used to generate a spectrogram, is 2D.

The short time Fourier transform of audio is a way to make a 2D image by tiling the 1D frequency domain data into a picture. Creating a 2, 3, 4... N-D picture of the 1D frequency domain vector doesn't make it 2D or anything else. It just means you made a picture.

FLAC / Rip CD to FLAC - can't locate FLAC.exe
Last post by Neildc -
Hi, I'm new to Foobar2000 and need some guidance in 'layman's language' please.

I have installed Foobar2000 v.1.3.19 and can use it to listen directly to CD's. However, when I try to rip a CD, I reach a windows explorer dialogue box asking me to 'locate FLAC.exe' and get stuck. I have read quite a few posts on similar questions though mostly 7 or 8 years old. They indicate the need to install an encoder. Is this still a requirement with Foobar? If so, please will someone point me to where can I find the right encoder to download and tell me how to link it to Foobar2000.

General Audio / Re: Undecoded Dolby A: Why People Complain That Digital Sounds Harsh

As far as I know blind tests have already been conducted between DSD and PCM and people couldn't hear a difference, despite the fact that DSD seems to be a broken format according to a paper published by Stanley Lipshitz and James Vanderkooy, which just shows us how forgiving our ears really are.
The faults are typically about 100dB below the music, so never audible. It was more an objection on principle.
Yes, exactly. I don't get positively excited when I see DSD printed somewhere, since I know any difference in format isn't audible. About that paper, though, the errors above 20 kHz were many, so I also got the impression that the paper was simply a demonstration of how DSD actually somewhat destroys the signal rather than improves upon compared to PCM - and hence DSD was just another marketing ploy.

Thanks. I seem to remember now seeing him mention it once. It even seemed like it was the same type of cancer that took my father away :-(.
