  1. I was addressing your explanation about HRTF in general in regards to binaural sound. It was not my intention to take away your contribution about converting ordinary stereo sound to binaural like sound with headphones as Ambiophonics itself believes that this is the future and currently working to create a 40 channel playback via headphones. Smyth Realizer and PS5 already implemented it. So too is https://audio-technica.embody.co/gaming?fbclid=IwAR0DO8ALsSLnoTQN6pGDvlnK1gWMuuwSbdtlbVXEHshYLxnbwJfGcOd1j4M I thought I was helping to make the point clear and in full s
  2. AFAIK, true stereo impulse response is a reference to 2 channels for each channel of the main stereo sound. This is known as interaural crosstalk. Ideally, loudspeakers playback should eliminate this and when it is eliminated the stereo playback transforms to 3D sound. Although, you will be restricted to the frontal 180 degrees and not much height information as stereo cannot encode height information. Headphones listening is not natural because pinna’s role is absent which makes the sound internalized ( like sounding inside your head). Sound will b
  3. I may have missed earlier posts here and therefore just confining to the last two posts where reference made to me. For YouTube video or even high resolution audio samples ( which is usually the case before it is compressed by YT), it will only be useful for system evaluation as heard in situ if it is recorded with binaural mics and played back using headphones. Binaural recordings capture the sound field. That is the actual sound waves arriving at your ears. You are not only judging the speakers but also the room acoustics. you are judging the phantom image that is created
  4. David, You may want to look at Tartini tones and intermodulation distortion that occurs naturally due to non linearity of the ears. Cheers, ST
  5. Actually I think Ambiophonics will make it worse because the recursive nature of the signal feeding more than the normal two signals of stereo. OTOH, it also helps to smoothen and average out the difference. The only thing we noticed is that room influence is lessen and we really do not know why as this involves how human perceive sound rather than measurements. With physical barriers to prevent the crosstalk then It is possible that Ambiophonics might mitigate.
  6. Hi AN, It will always exist because we are receiving two inputs via two ears. All sound when reaching the ear drums already altered even for ONE mono signal due to the difference in the pinna between left and right ears. You are always listening to two inputs at all time which cannot represent the exact measurements ( sound waves) as the original even after taking into consideration of frequency shaping by our ears. Furthermore, our ears are not fixed in space as we continually move even when you try to hold your breath. Even the slightest movements alter the FR that reac
  7. It is because of the setting. Otherwise, I don’t see much difference and listening tests using others seemed to prefer one with crosstalk. See if you perceive dryness in this recording. But this is a binaural recording so some tonal difference is possible due our pinna difference.
  8. I did not read all the posts. I only read the first post and your post quoting me so what I reply is confined to these two posts. I will be emphasizing the word ONE in my reply here. In audio, we measure only ONE signal at a time. A reproduction of ONE signal ( channel) always correlates with measurements for assessment of sound quality. All sound that reaches our ears are a mix of direct and reverberation. In live concert, the indirect sound of the reverberation make up more than 80% of the sound we hear. These indirect sound hardly represents the exact sound waves of the
  9. That is the point. This is audio. Not about someone’s mental condition or belief. I have always been open to others opinions irrespective of the equipments or background. Disagreement is normal when things involve subjectivism but that doesn’t take away the hard evidence. For three years, the Premium member Fas42 gave the impression that the magic sound was possible with laptop speakers or the Philips and sharp system. Now it turned out that he was describing to a system that was made of B&W speakers and Perreaux Amplifier. The hobby has developed to hallucination. An
  10. So my posts were sophomoric? one delusional guy took us a ride for over thousands of post when all along he was describing the sound of an average high fidelity equipment and another one with damaged hearing siting with headphones lecturing me about downsampled Dolby. and my posts got deleted.
  11. Not as confused or delusional as you are Who is trying to convince the world that the laptop speakers can sound as good as the B&W. You made this statement so please explain why that is so start with:- Speakers wired out of phase, can make the speakers disappear. Can I now say the SQ goal has been achieved? This is irrelevant if can’t explain the earlier. Anyway, I take it here the best sound sound you had was from the proper hifi system. That is the final word about your 35 years journey.
  12. I disagree. Dolby surround is stereo plus surround. The stereo sound is always there whether it is 2.0, 2.1,5.1,7.1, 9.2, ATMOS, AURA3D, WFS and etc etc. You need stereo to produce the frontal stage as close as the original event. Stereo is the simplest way. When you refer to downsampled version of DTS or Dolby, how do you know it is the downsampled version? Dolby surround is object based. Stereo recording is channel based. Most of my collection that I like were from original motion picture sound. The audio CDs will be in stereo. However, the videos or movies will have
  13. I think we should know by now that whatever magic sound he was referring to l, that happened 35 years ago, happened with a proper hifi system. He is still chasing for that sound with Philips, Sharp and laptops which will not materialize but he somehow believed that it did on several occasions. Sometimes, I also ask myself whether my tiny phone could produce the same sensation as my main system if I ignore the volume. It is funny that I can actually equate the same sound with the main system. It is just the state of the mind. But to believe that it is actually the same as the main sys
  14. Now you are are talking like a typical audiophile. It is a normal behavior to find that your system not to sound optimum and lacking once your initial euphoria of getting a new toy is gone. Dr Henry Augus Bowes identified this as audio neurosis in 1957. It is your brain reminding you that the stereo sound is not natural.
