Webb12 okt. 2024 · We prefer the slow roll-off filter (indicated by a blue LED) for its slight edge in exactness and naturalness over the warmer, more rounded sharp roll-off, signified by a purple LED.

Webb10 feb. 2024 · Few days ago I realized, that Super Slow Roll-off filter or NOS I quess on my AKM4493EQ suits best to my listening requirements. I'd always had difficulties with strangely bright treble and this filter makes it right, neutral. Bonus is cleaner soundstage. Webb11 dec. 2024 · You are right. Minimum phase = sharp EQ roll off, more post ringing. Linear phase = slow EQ roll off, pre and post ringing. Then forget what I said. Whatever the slow rolloff is. Fixed my post. Also, the NOS filterless I have is the 1541x4 that naturally has slow rolloff beginning around 10k anyway on the output. firt smith ar weather

"Webbuse a sharp digital anti-imaging filter followed by a slow roll-off analog filter having a cut-off frequency far above the audio band. In light of the foregoing, it is now possible to define the term “upsampling”. An upsampling digital filter is simply a “poor” oversampled digital reconstruction filter having a slow roll-off rate.

Webb10 mars 2024 · Those kind of filters remove pre ringing and reduce post ringing. This is quite important, as most dacs default to a linear fast roll off filter for pcm, which doesn’t remove any ringing at all ! And he admitted he forgot about this quite important setting of his dac. He had been listening to pcm using a fast linear filter during the comparison.

The 'Short Delay' filters F-3 and F-4 are minimum phase and have lower latency but non-flat phase response, while F-1 and F-2 are linear phase and have as the name suggest flat phase response but higher latency.

Webb10 aug. 2024 · However I don't like the HF roll off. So I tried my own PEQ filter in order to correct the roll off. I then found the one posted here for NOS. I will try that shortly. But my lack of understanding leaves me a little confused. I am trying to get CDs to sound good at 44.1kH sampling. So the filter published here will correct the HF roll off.

But it’s known also as “Optimised Transient” (in a Pro-Ject Audio DAC) and zero oversampling, or NOS, for non-oversampling. This is kind of a reversion to the earliest Sony-style resistor ladder digital-to-analogue conversion I described earlier. Visa mer Yes, first, we need to understand some basics.

WebbI use the default, or at least I think it's the default, checking, I have it set to "Apodizing fast roll-off filter type 1". I don't think I can hear a difference either. Theoretically, slow roll-off filters should attenuate the treble, they are called slow roll-off because they roll off more gently, starting to roll off at some point under 20kHz.
