Webb27 juli 2024 · With every DAC I had ... well, it was only really Topping and Gustard DACs that ever gave me the option to select roll off filters, I came to the same result. I tried about all filter modes, some with lesser and some with greater difference. But with passing time I found myself preferring the slow roll offs .

Webb5 juni 2013 · Using an onboard ASRC chip, the upsampling algorithm does a excellent job achieving a sharp frequency roll off to prevent signals going beyond Nyquist. Here's the 19kHz -10dB signal: Very nice - even cleaner than the SHARP filter (as one would predict given the lower temporal resolution). Some harmonics present but no aliasing distortion. Webb8 jan. 2024 · Fast Roll Off was selected by default (could be also because it's the first option).

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. biomedical engineering jobs in north carolina

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.

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. That performance reveals itself through the phono stage and 6.3mm front-panel headphone output, too – it’s cohesive and punchy, but falls a little short of the … Webb12 feb. 2014 · Slow roll off filters used in dac side (playback) improve impulse response ( this I understand ), what I don't understand is why would aliasing occur if the low pass filter cut off frequency is lower than the mirror image frequency since the image frequency is pushed higher when oversampling is used?

WebbSlow roll off reduces treble slightly. The short delay options are newer technologies/algorithms. I doubt most people can hear the difference. The filters are doing things in the 20-22Hz range...upper limits of our hearing. I have the Fiio M11, and the default is the "short delay sharp roll off filter". So I keep it on that.

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.

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.
