- Depending on the tools, upsampling could sound the same while others make it sound worse. I converted the Paper Mario 2 files to 44.1 kHz once and it sounded exactly the same while someone else's conversion was slightly distorted.

- How exactly does upsampling work? How does a program generate the extra samples to make it play properly, and what effects does it have on the sound of the file? I thought it wouldn't affect it at all; that it would just be extra useless space...

- This is how I see it. Upsampling will make it sound the same, depending on the factor.
Upsampling 32000 to 48000 for example, wouldn't work, as, well, every 2nd sample of the 32000 Hz file would have 2 samples either side, and that original sample would be missing
However, 24000 Hz to 48000 Hz would work, because you'd only be adding an extra sample between each sample, while no samples are lost.
Upsampling from 32000 to 44100 is even worse, because the only samples that wouldn't be lost would be after every 320 samples on the 32000 Hz, which would be 441 samples on the 44100 Hz, and it'd be completely out of sync.
I would visualise this, but FUCK THIS FONT FOR NOT HAVING EQUAL SPACES BETWEEN CHARACTERS.

- Mods, switch the font to comic sans please.

- Any loss in upsampling is going to be due mostly to the sample precision (16 bits in modern formats), with a quality upsampling algorithm. The exact sample numbers won't exist in the upsampled audio, but the set of frequencies that make up the signal can be just as well represented as a higher sample rate. The trick with doing upsampling correctly, as I understand it, is to avoid introducing any spurious higher frequencies.
A good reference

- Miss the "double cherry pass" underwater version which can be hear underwater in the "switchboard falls" level ^^ (super mario 3d world)

- Double Cherry Pass doesn't play in Switchboard Falls. Chain-Link Charge does, and the underwater version is done by in-game effects I assume.

- He probably got mixed up by the album names, translations and all.

- Noticed a few special 48Hz songs that are in true quality in SSB U this time around that are from Melee. Pretty cool. No idea why they didn't work from the source material for the brawl tracks. Here's a list that are in true 48Hz
snd_bgm_W01_SMB_PeachJyou
snd_bgm_W07_KBY_GreenGreens
snd_bgm_W08_SFX_Cornelia
snd_bgm_W09_PM_PokemonStadium
snd_bgm_W13_ICE_IcicleMountain
snd_bgm_W27_MR_Brinstar
snd_bgm_W28_SFX_WakuseiVenom
snd_bgm_W29_FZR_Mutecity
snd_bgm_W35_SBDX_Menu_ver2
snd_bgm_W36_ZLD_GreatBay (mostly resampled, not true 48khz weird because its a remastered version compaired to the Melee version)
snd_bgm_W37_STR_YoshiStory
snd_bgm_W41_SBDX_FigureMeikan

- Based Audiophiles, I get all giddy inside when these kinds of discoveries are made.
