i downloaded yt videos using savefrom and the sample rate seems to be 44100I am a newbie on this topic, but I think there could be some potential advantages to using a higher sampling rate than 44.1 kHz as well.
Most of my listening is via the standard YouTube platform, which apparently uses two different codecs for encoding its content, AAC at 44.1 kHz and Opus at 48 kHz. My browser (and I guess also alot of other recent browsers) seems to prefer using the newer Opus encodes though, over the older AAC format. Perhaps because they sound a little better, and maybe are also a little easier to stream.
That 48 kHz rate in the Opus codec makes perfect sense btw, because that is the rate that most video devices use. While the older 44.1 kHz standard seems to be falling increasingly to the sidelines. YouTube apparently still uses it though to ensure backward compatibility with some older browsers and devices that don't include support for the new Opus encodes. And it is also possible that other streaming platforms are still using 44.1 kHz as well. So you'll have to check the specs on those.
You can see which codec is being used for playback by your browser in the "Stats for Nerds" pop-up menu, if you right click on a YouTube video while it's playing. That brings up a display that looks like this...
The audio codec should be the second item listed on the Codecs line, encircled above. If it's using Opus, then the sampling rate is probably 48 kHz. If it's using AAC, then it's probably 44.1 kHz.
If you are uncertain about the sample rates of your content though, then maybe using an appreciably higher rate, such as 96 or 192 kHz may not be such a bad idea. Because that could possibly reduce the potential for aliasing artifacts due to conversions from the lower sampling rates. (Edit: Others with possibly better informed opinions below seem to have more doubts about this.) The same goes for the bit depth. A higher bit depth will reduce the potential for resampling errors, especially if you're using an EQ to digitally alter the volume of your content at different frequencies.
Latency could possibly be another factor though with the higher bit depths or sampling rates. So that may be a consideration as well, particularly if you're using your PC for alot of gaming. And I'm not sure what the preferred bit depths and sample rates would be for that.
I'm not familiar with Foobar2000 or WASAPI btw. If you have a decent DAC though, and those programs will bitstream at the content's native rate and bit depth to the DAC, then there may also be some advantages in that.
I was using 16/44.1 before btw. But recently switched to using 24/48 after installing some EQ software on my PC to tweak the sound of my headphones a little better. And I think I'm hearing a noticeable improvement in the sound quality when watching YouTube videos encoded with the Opus codec via my PC with the new settings, for all the reasons outlined above. 24/48 is also the highest setting supported by my audio device, which is a Samsung TV connected to the PC via HDMI.
(but tumblr seems to use 48000hz)
