    How do you measure sound stage?

    Excellent! I will too... soon!

    How do you measure sound stage?

    Very good! Notice I said "should be" not "are". Can you distinguish that?

    How do you measure sound stage?

    Of course! Note the asterisk. No, I'm not restricting the idea to humans. Neural networks (see wiki) are amazingly good at pattern recognition, including using audible cues to detect location of one or more sound sources, They can be biological ("meat") or mathematical ("silicon"), as in the...

    How do you measure sound stage?

    You are out of your depth and simply speak with no authority. First you say it's in the mix and the only relevant measure is channel separation (LOL). You also mentioned the impact of DSP, and now you say the room. I'd say it's in the vibrations of the 2 tympanic membranes*, the brain's...

    How do you measure sound stage?

    It is fun to speculate "how could it", but ultimately your question is number 3 or higher... 1-Can a neural network (meat or silicon) reliably hear a difference in DACs? * If yes, 2-What are the measurable differences in signals? ** Then maybe, 3-How can those measurable differences be...

    How do you measure sound stage?

    Did anyone read this article? I don't mean quote mine to cherry pick support for your existing firmly held views. I mean read the article. I might just eventually read it for my own interest. But if someone else has read it (or plans to), I'd be interested in discussing whether/how it informs...

    Resources to learn about DAC design, topologies, filter design and all that?

    You are trying to derail yet another thread. Stop! This is so ridiculous, even you contract yourself just a couple sentences later: You don't think "getting going" starts with a basic understanding? You don't even think an EE has gotten going? Have you read the wiki article and the DSP book I...

    Resources to learn about DAC design, topologies, filter design and all that?

    Gerne! As I mentioned, further questions may better target and speed up your goals! Also, I'm more of a reader than a video-watcher (my son is the reverse), so I neglected to mention Monty from Xiph who makes great videos! Others here probably know other nice resources... anyone?

    Resources to learn about DAC design, topologies, filter design and all that?

    I'm not completely clear about your background knowledge or whether you're asking about DAC chips or the DAC within a complete system. These may (or may not) help get you started: Wiki in English or Deutsch A really nice DSP book online, with the DAC chapter here (ADC and DAC). Ask, if you...

    Audio Science Review AES Paper Presentation on Audio DACs

    Do you think he knows you're talking about him, or is he blind to it?

    Continuation of Mr Haelscheir's excellent thread responding to WaveTheory's video series on cables mattering for audio

    I agree that below 5kHz it does look interestingly like simple delay. The problem with that idea is the phase wiggles a bit between about 7-9kHz and 13-15kHz but is mostly rising (a lot!) above 9kHz. Do you believe the simple delay knows to begin stopping the delay above 5kHz? A...

    In-ear microphone cable measurements for planar magnetic headphones - FRs are indeed identical

    I created a new thread to continue discussion of the first couple pages (https://www.head-fi.org/threads/continuation-of-mr-haelscheirs-excellent-thread-responding-to-wavetheorys-video-series-on-cables-mattering-for-audio.970430/)

    Continuation of Mr Haelscheir's excellent thread responding to WaveTheory's video series on cables mattering for audio

    I was very interested in @WaveTheory 's take on this topic, mainly because many keywords from his background also apply to mine. Alas, I was a bit disappointed. His pedagogic choices for presenting the material to the lay public are not the same as mine in Episodes 1 and 2, but you say...

    Continuation of Mr Haelscheir's excellent thread responding to WaveTheory's video series on cables mattering for audio

    @WaveTheory 's video series is called: Cables Matter: The Science Behind Hearing Differences in Audio Cables. There are currently 4 videos discussing the topics and 2 with multiple mini reviews of cables. He plans 2 more videos discussing the topic. Whereas @MrHaelscheir and others praise...

    Continuation of Mr Haelscheir's excellent thread responding to WaveTheory's video series on cables mattering for audio

    @MrHaelscheir started a thread with a great first post that resembles a mini scientific paper, with intro, methods, results and discussion. An important component is his inclusion of his own measurements. If interested in the topic, I recommend reading the first 2.5-ish pages of his thread. As...

    In-ear microphone cable measurements for planar magnetic headphones - FRs are indeed identical

    I can't imagine your gaslighting complies with the rules. It certainly is an ad hominem attack. Please stop gaslighting!! But I haven't posted here in a very long time... perhaps one of the "regulars" (very, very regular!) might have more pertinent advice for you: That was quick and dirty...

    Two noob questions

    I'm not sure what edition this comes from, but the latest edition words the description of the figure quite differently.

    Two noob questions

    I asked you a question, but you seem concerned about other things. Do you see the difference in their 2 explanations that directly affect the conversation? That would be the next step if a convo about digital audio continues with you.

    Aha, I just saw you added to your post... I will send you a PM/DM in a minute.

    Two noob questions

    I see where you're going. I try (and sometimes fail) to separate concepts from real-world circuitry. I'm unaware of hardware like you describe (but that doesn't mean it doesn't exist). But what you describe sounds very much like a mixture. If you multiply a series of impulses with your filtered...

    Two noob questions

    We all know you love to argue and it has gotten you in trouble. I also love to argue, sometimes. But this is not one of those times. So I won't be answering this theme of how we interact, rather, I'll only answer about digital audio (to you in this thread).

    Two noob questions

    The lowpassed analog signal is meant to be reproduced. Yes, I would call this a sample-and-hold. I don't know the latest stuff, but there used to be "Flash ADCs" that didn't have this: the ADC was faster than a sample-and-hold, so it wasn't needed/used. No, there are no aliases there. This is...

    Two noob questions

    Nope, your understanding is wrong.... Do you want to continue with this? Then I'm out... Or do you want to discuss digital audio. Lavry and Pohlmann didn't make it up, but their explanations are different in an important way. So is only one right, or is "how to explain it" a subjective call...
  24. SoundAndMotion

    Two noob questions

    I want to understand what you mean by "sampler"... I have a guess, but let's be clear. The ADC process includes several steps: there may or may not be a buffer amp, but there will be a filter. Depending on the ADC method, there may be a "sample and hold" circuit (is this what you mean?). It is...

    Two noob questions

    Ok, I got in a couple jabs and you got in a couple too. I'll try to stick to digital audio. Do you want a hint about where Lavry and Pohlman disagree... I would disagree with both of them on the best way to teach this. You are quite right Pohlmann is one of the most "widely read/referenced...
