@Shanling What digital filters are best to reduce high frequencies?
I stumbled onto some YouTube videos but it’s a hassle and in general I think I need more explanation.
Edit: I found this on FiiO about the same dac chip.
@Audiophile PT I guess it will be able to help you out. If I’m reading correctly, 1/2 are cutting off higher frequencies faster or smoothing higher frequencies. Anybody know how to works?
1) Sharp Roll-Off Filter: full and rich sounds, positioned at the very rear. It is suitable for pop music.
2) Short Delay Sharp Roll-Off Filter: robust, thick and atmospheric sounds, positioned at the rear. With accurate sound positioning and enough sound thickness, it is suitable for pop music.
3) Low Dispersion Short Delay Filter: neutral sounds, positioned near the middle. It is a traditional filter that can match different music styles. If you have no idea about the filter, you can choose this one.
4) Slow Roll-Off Filter: coherent and clear sounds, positioned near the middle. It is suitable for classical music.
5) Short Delay Slow Roll-Off Filter: ultimately untouched sounds, positioned near the front. It can create an immersive music environment with clear and uncontrolled sounds, which is suitable for classical music.
6) Super Slow Roll-Off Filter: soft sounds, positioned at the very front. It is fast with relatively clean sounds.
I’d really love an answer from
@Shanling about filters and what they do to the sound. It’s nowhere explained.
