To a certain extent, the lossy encoding is too (try streaming FLAC encoded audio over a 3G cell network with spotty coverage in a moving vehicle, and it will become a lot more apparent why), although a lot of sites take that way further than they need to (I regularly cringe when I see someone streaming audio from Youtube or a similar site), but neither of those points is particularly relevant to your primary complaint. As far as the SNR, if that's an issue, you should be getting better quality audio hardware so that you don't have to deal with the noise, as once the signal is analogue, the bit depth is irrelevant to the SNR, and most of your noise will be introduced on the analogue side of things.Īs far as the sample rate, anything over 48k is pointless for regular distribution, because even that is above the nyquist limit for human hearing for more than 95% of the population, and if you're using good audio hardware at 48k, you should observe zero aliasing for any frequency below 16KHz (which is a reasonable upper bound on the frequency of most audio recordings), and almost none up to 24KHz (and if you actually have audio files that include anything higher than 20KHz, you're deluding yourself in other ways).ĭRC on the radio and streaming is a necessary evil, for exactly the same reasons that having a high dynamic range in audio is an issue. The problem with music that has such a high dynamic range is that you need an almost silent room to listen to it and get the whole range, which is not a luxury almost anyone has. Now, on the other hand, avoiding the dithering and quantization issues is a practical reason to want to avoid Pulse (especially because a lot of high-end audio cards do up-sample to their native sample rate and format before doing any internal processing). It's like the difference between using 24-bit color and 48-bit color in image work, there's minute differences, but better than 95% of humans can't tell the difference.Įven people who work for have written articles on this: For example, if you give me the same audio encoded in a 128kbps MP3 file and a FLAC file, same sample rate, same bit-depth, I can roughly 80% of the time identify which one is the MP3 just by listening to them both, yet I know numerous people who claim they can tell the difference between 44.1k and 192k sample rates who can't do the same better than about 50% of the time (which pretty much means they're guessing). 24 versus 16 bit audio doesn't make as much difference as you think either.Īnd easily audible for you doesn't mean it is for everyone either.
