Do you hear a difference with DAC filters?

[Basic Channel]

Please remember that WTC turned the European music into the 'false'.

I was doing a play on the word "temper" in case you are maybe not a native speaker.

Do you know why bells sound like bells? Or what octave stretching is?

Yes, of course.

I know hifiers whos never disturbed by a pre-ringing effect; I know hardcore NOS belivers too. If you listen non-acoustic music you may prefer the 'Sharp' filters as well.
That's why AKM gives these filter-possibilities.

It's an incredible amount of effort to put into small differences in high frequency "air" imo.

Do you have acoustic treatment or calibrated measurement microphone?

I suppose you'd be appalled by my ECM8000 or the Freq response above 200hz being about +/- 3 or 4db.

How to pick the best filter setting for your dac

I think it's a technically correct text. Maybe help to understand what's happening.
But I think the opposite nowadays.

 

[SIY]

Mostly. But... he falls into the trap of using an illegal signal for the impulse, i.e., not band-limited.

At first I didn't understand it:

(sharp filter)
How can it be possible?
That echo overtakes the signal itself?
Then experts explained that digital conversion is not a true real-time conversion what steps ns by ns after each other. Digital signal is going to the chip then the conversion is producing the analogue signal even the above way - the two 'times' are different; similar to the procedure when picture is realized on the paper after shooting by a camera.

Don't know what you are asking. @SIY gave you the correct answer. To get graphs like what you have post, you need to feed the DAC an "illegal" signal with infinite bandwidth, i.e. an impulse. Music is encoded at sampling rates that far limit its bandwidth and hence, you are not going to see that kind of ringing.

Any signal that reaches the DAC is legal by definition. What you and @SIY mean is that microphone recordings of natural instruments/voices made with an ADC and then played back without any processing -- except proper downsampling maybe -- cannot and do not contain signals that provoke extensive DAC filter ringing.

The moment electronic instruments are used or heavy nonlinear processing is applied (like compression and hard limiting, but even simple editing without crossfades) the signal *will* contain "edges" that provoke DAC filter ringing.
Same story with intersample overs.

Can you elaborate on what you mean here? Do you mean in real time, because once its made into a WAV file at 44.1k it cannot contain "illegal" frequencies above nyquist.

That is far more restrictive than what Amir and I are saying- ANY impulse, including electrical, MUST be bandlimited to fulfill the Shannon-Nyquist conditions. If you create a file (this is not a signal, this is a created file!) and bypass the antialiasing filter, that violates Nyquist-Shannon. So you're removing an essential component of the ADC-DAC process.

A legal signal for evaluating impulse response MUST be bandlimited to 1/2 the sampling frequency.
