In theory, human ears perceive everything from around 5 Hz to around 21 kHz if you're a baby, around 19kHz-20kHz when you're teenager, then it drops to around 17kHz-18kHz when you're 20-40 years old and drops slowly as you're older. However, if you set to higher than 48000 Hz pretty much everything will use 48000 Hz or less, so Windows will have to use some CPU to resample everything to that higher Hz value and waste cpu cycles and potentially introduce latency.įor example, you have in background youtube playing some video with 16bit 44100Hz 128kbps audio track and you have a game playing at 48000 hz by default, windows will have to resample both of them to 192000 Hz. I may be wrong but Windows mixes various sources into single streams, so if a software outputs 16/24 bits 48000Hz and you have 24bits 48000 Hz set, Windows just copies the data over without processing and no cpu usage.
Only music ripped from audio CD's (mp3) is in 44100 Hz and can be easily resampled to 44100 Hz.Ĭonversion from 16 bits to 24 bits is also super easy and uses barely any processing power (almost unnoticeable, and worth it). I usually set it to 24 bits, 48000 Hz because that's the most common format everywhere.
