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 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.

Using a fast roll-off (“brickwall”) minimum phase filter instead eliminates all pre-ringing, so that may be a better choice. fear photographers

If it’s a DAC digital filter control, just use linear phase unless you want to risk your music to have aliasing (or imaging). They do stuff from the end of the passband to the start of the stop band (from the cutting frequency to Fs/2). deb kim wheatonWebb1) Sharp Roll-Off Filter: full and rich sounds, positioned at the very rear.

WebbA slow roll-off filter allows more high frequency energy through compared to a fast roll-off filter. Therefore, the slow roll-off filter has better time resolution, or equivalently, less … 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.

Webb15 sep. 2024 · The square wave response here shows that the slow filter on my DAC is minimum phase. But not all "slow" filters are minimum phase. Some are still linear phase, but use a wider transition band (like filters #1 and #5 on the WM8741). This leaves me wondering what that would look like in measurements.

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.
