There sum (interference) of direct + bounced + re-bounced [infinite thin] acoustic rays from acoustic source in a point. These rays may propagate differently for different frequencies (depend on source and its environment). Sum is complex (in math meaning) and it is sum of amplitudes and phases of all rays. Rays have different sum in each point. We can consider all surfaces of ears, inner ear, face bones as the points. I suppose, there is many nerves are used in these points. And brain get and process more sophisticated picture, then come to ears, to localize sound source. To emulation of place of sound source, sound engineers can use: time delay between channels; level difference between channels; EQ; total source track level; other; complex of these action. I suppose, modern systems try build ray propagation model and convert it according channel number. Remarks: The rays are virtual. But they are need to classical math description of wave propagation and interference. Phase is like to time delay, but it is angle (angular coordinates). Sum is not constant. Sum is oscillation.

How to listen speakers? [step-by-step] I suggest, listen speakers in usual position (like it shown in speaker user guide). Speaker have apperture (angle dependency of frequency response). So different positions can cause different impression. Listrening room is very important matter. It should have middle of high sound absorbtion. Don't use rooms with many glass and ceramic surfaces. As test stuff, I recommend: - bass note sequences from lowest to almost midrange. What listen: Resonances, how notes are separate. - cymbals. What listen: So callsed "send". Distortions on high frequencies. - trumpets. What listen: "Oil" in sound. - stick on snar, acoustic guitar. details so touch to instrument, scratches of strings, attack of notes. - classical compositions with very loud and quiet places. check sound "transparency" and so called "air" on quietest level places of a tested musical piece. Number channels is not matter. Before listening multichannel system should be adjusted/calibrated (if you like calibrated sound more).

Hi @The Computer Audiophile I never say it. If somebody think, that, I'm wrong, let's him show quote (with link). May be I'm really wrong there. But I'm very careful about my competitors always.

Where I said this?

I can't give advice, ask you him or not. It depend on, want and ready you and he discuss it or not May be I'd ask, what he meant as "closer to analog". Example in addition to my previous post (about {DSD bit stream is a lot closer to analog than PCM}): I seen the picture where was shown lesser ringings for DSD system comparing PCM one. But I understand, why it so. It is matter of band width and used digitial filter steepness. If we expand band of PCM and apply non-steep filter we get the same ringing.

You understand how to work software, that you never designed, wrote and debuged or seriously research? It is too optimize claim for any experienced engineer/programmer/manager, who works with a complex project, even. May be you just read at AccurateRip site how it works and rip number disks? "you are violating forum rules" looks like way to remove opponent in argue when no other arguments. I discuss concept, not software. I says that the concept neither good nor bad. Me only need new information about the concept. Do you understand it?

Ok. If you'll have time, write me. I use Drupal and custom theme. Standatd themes may be not so responsible (time of site opening, that impact to rank of site and view page time, that impact to the rank too). But good design is very important too.

All correct. I wrote, what need take and move demo window. After ripping, interface show table with ripping results under log. Though, in demo really no access to track ripping result visualization. You are right. Probably, in further versions I'll remove closing of application after demo window closing. Tell me about other issues, please.

I never told that it don't work. I don't know the system figures. It was big research? It's fine. Just show us methodics and protocols.

Do you really designed or programmed AccurateRip? Or you just have read its site something?

Common words without figures. Discussion is cycled. Help @kumakuma to answer my questions for experts.

I like that we discuss certain things now. If you are expert in rippers you should know, why it so and why it need. And what happens, if reduce the time. There is elementary answer, if you learned programming code or read about secure ripping of some rippers though. There is @Ralf11 said, that he expert who able to estimate my knowledges. Ask him. Really? There detailed information is displayed: you know where and see what is error there for each sample of each track. Shift demo window after ripping. Read details: https://samplerateconverter.com/cd-ripper/visual-cd-rip-error-display Learn stuff about other rippers and secure ripping. Try plays with settings. Probably, you are wondered. If you are expert, you should know why it need. Practically, I don't noticed any ripping impact to multiple and multiple ripped test CD kit. Let's ask expert @Ralf11 or learn rippers yourself. Write details, please.

All clear.

I lIke that you think, that you expert in probability theory. Take one of my formulas and analize it right now. WARNING: there is need to be expert in CD-audio too.

Nice. But here need more details. Including details about correctness probabilites fo all these "4477 drives" and ? rippers in each version. May be you read something at AccurateRip site. Do you really think, that you know enough, how to works multiple software, that other people designed?
