Some applications control themselves whether new files will be opened in another tab, or whether a new instance of the application is required.

I guess that people who don't care about choosing which (of 6 alternative files, here, for different target architectures and different types of installer) they wish to download are also those unlikely to care about checksums.

That's not a /file/ download page, but instead a folder-choice page. If you click on the folder representing a particular release of 7zip, you'll then see a list of downloadable files, and for those the i-icon is shown.

I agree about the 7zip website itself, but why are you criticising Sourceforge? They do list hashes for every downloadable file - click on the I-in-a-circle ("info") icon at the righthand side of a file's listing - tooltip "View details" - and you will see SHA1 and MD5 hash values. If one wanted to download many such files, all those clicks and having to c&p the values would be a nuisance, but for a few files it's not difficult.

I asked above: It doesn't completely explain it. Why would reading files to index them alter their date of last change? Maybe the "last change date" changes not because the file has changed (hopefully it hasn't) but because metadata has changed saying it's been indexed? If that's the case and then someone actually changes the file I wonder if such an indexed flag gets turned off so the file can be indexed again?
-
It doesn't completely explain it. Why would reading files to index them alter their date of last change? You might expect the date of last access to be changed during indexing ... but under NTFS that often doesn't happen either. There's a FS (file system) setting that disables logic that would keep date of last access accurate. Apparently years ago this was introduced to make file operations speedier on slow disks.

Have a careful read of this, and think about it. Ignore the marketing hype. https://www.mojo-audio.com/blog/the-24bit-delusion/ And, as I said before, find a pro-audio group to discuss stuff with... eg (usenet) rec.audio.pro - which you can also find at: https://groups.google.com/g/rec.audio.pro

@ipavlov - the filters stuff is interesting! Stephen: for your friend, yes, 16 bit. For you... well if your scarlett 4i4 is 3rd generation, whose specs I read here: https://focusrite.com/en/usb-audio-interface/scarlett/scarlett-4i4 note what it says about the unit microphone inputs: their dynamic range is 111dB, which is more than can be expressed in 16 bits.

24-bit isn't just "overkill". Overkill would be storing a 24-bit value at eg 96 khz or 192 khz... ie using the hardware to store a very detailed sample. In your case if the source is 16-bit, storing that as 24-bit does not add any quality or detail at all. A 16-bit sample (produced by the USB mic) does not become more detailed if you store it as a 24-bit number. It is stored as 16 useful bits and 8 zeros. It doesn't matter what's in the 16 useful bits (they could be ones or zeros) but the extra eight...

Ah, ok. But note that spoken voice (unless you're actors/singers) is likely to have a smaller dynamic range than voice performers, or screaming. When you connect the mic to an audio interface, it means that analogue audio signals, probably very weak, are being sent to the interface. Whether the connection is by XLR or something else doesn't necessarily mean much, though one would assume that XLR means balanced audio rather than unbalanced. The "audio interface" would possibly be providing phantom...

Looking at the audio level stats quoted above...

If your voice is "very consistent" with hardly any difference in dynamic range, then /you/ certainly don't need lots of bits. Even if your friend has a truly amazing vocal ability (opera singer?) he will not be able to vary the sound level by anything like even 16 bits - ie 96 db. Get real! I do understand the point about DAWs using 32-bit internally for their conversions, but that's got nothing to do with the resolution you need to store in your files. Provided you've recorded each voice so it peaks...

The screenshot of the hex content of the audio will tell you nothing useful, as it must represent only a tiny period of time - maybe a microsecond or less? And anything (untypical) could have happened in the instant that you're looking at. You need to find far more out about about things like average and peak levels in each audio file, and possibly do that for every few seconds. You also do need to be comparing similar things. Eg do you and your friend set reference sound levels (eg 'slate tones')...
