Sorry that this is a little late, and unfortunately most of these resources are paywalled. However, K-weight basically normalises the volume by frequency so that for a given LKFS (for example) 1,000 Hz tone, 100 Hz tone and 10,000 Hz tone sounds similarly loud perceptually (while if we set them to similar dB instead, 1,000 Hz is perceptually louder than 100 and 10,000 Hz tones). Of course, being perceptual, it's more accurate to say that it's what an average person would perceive so it can be off for some people (but like with colour this is a rabbithole of topic).
- karmakaze 5y agoAh thanks. There's not much to find about LKFS/LUFS. I find something about dB(A) vs dB(C) vs LUFS[0] saying: > Finally, we come to LUFS measure, which is intended to reflect how we perceive loudness. It also isn’t particularly concerned about frequency response either. It has simply been found that by using a shaping filter ahead of RMS power measurement, with the lowest bass below about 37 Hz eliminated, and sounds above 1.5 kHz boosted by 4 dB, gives a gated RMS measurement about the same ability to predict human loudness perception as real listeners engaged in comparative studies.
