如何计算Audio Sample Rate
learn.whatIsHeading
The Audio Sample Rate Converter shows Nyquist frequency (half of sample rate) and file size in MB for uncompressed PCM. 44.1 kHz (CD), 48 kHz (video standard), 96/192 kHz (hi-res studio). Higher rates capture more detail but quadruple file size with diminishing returns above 48 kHz for most listening.
公式
Nyquist = Rate / 2; FileSize = (Rate × BitDepth × Channels / 8) × Seconds
