 Hi folks,


my name is Stefan Michael, I am a child of the 80s, am living in Germany, close to the Northern Black Forest.

I am an audio enthusiast, a music lover and above all -and thanks to this pandemic- a passionate new-starting creator.

I hope you are doing well.

As Christmas and 2022 is (finally!) around the corner - I wish everyone happy holidays and some time to relax!

The one gift I would like to drop here -which I assume I may- are two words that have always filled my own heart with pleasure:

'audio' and 'microcomputer' - now if one would be searching for these two terms on yt,

one may find something intriguing that may help to stop thinking about the world for approx. 39 minutes,

something that I have been working on for many years in silence,

which just saw the light of day.

As it is audio- and digital-drive-related, and as it's soon going to be Christmas, and as few probably ever heard of me publicly regards it before,

well, this post may well be worth a shot. :)

Stay healthy!

 Hi, Stefan,

Welcome to the AA site!

I just did a YouTube search on "audio" and "microcomputer" and didn't see any result which lasted close to 39 minutes. Would you be able to put a direct link in your post to the video you have in mind?

 Hi Chris,


thanks so much for coming back to me,

now I don't want to be banned regards this, but there are two possibilities, one, either search "audio microcomputer" on yt, it should lead to the result (it does on my pc) or put those words together, leave out the blank space and try the c o m - domain for a forward to my Patreon site where my yt video is embedded aswell.

Still having troubles? Write me, we will sort it out. :)

Regards,

Stefan Michael

 I am about 20 minutes into this Video and still do not have a clue as why I would even want this product, or exactly what this product does.

I suspect that towards the back end of the video, you probably show why an Audiophile might want this product. I had to quit watching, as it was getting too painful to follow the minutia of what you were doing...

So my Suggestion: You probably need to reverse the content of the Video... Like showing what this device will do and why it might be wanted by an Audiophile... Like the First 2 minutes of the Video... The first 20 minutes of the Video could be shown at the very Back End. (Which most people here might not even be interested in)

 Hi there,

well, thanks for the feedback.

Deceleration is one part of the philosophy of the whole device, so I won't be rushing through things, which may not suit everyone perfectly but that is to be expected as everyone is different, and rightly so.

I am also targetting a broader audience, I mean not just the listener but GNU/Linux programmers and the RPi community aswell, so the level of detail might be too much for some and then too little for others, depending on the background.

A look into the video description may have revealed a time stamp when the audio example would start. I have included that for a direct jump to it for those who preferred that.

Unfortunately due to a copyright issue and potential copyright strike as of now I will have to leave out the Genesis snippet which I found very well-suited... but because of the re-encoding of the whole video by youtube I will likely be putting this completely down again and will have to re-upload it, perhaps with another snippet, because the new timing probably won't meet my expectations now.

Kind of a pity I had to delete the Genesis song. If this isn't fair use for transforming original material with new expression and context in an educative way into something new, what is ?

The fact to have managed to even get this effect to be included via a streaming conversion was not granted from the start, as this is quite a delicate task after all the processing that is being added for and to uploads. Just saying.

Regards,

Stefan Michael

 Well, that's great! I own 10 Raspberry Pi for Streaming Purposes. But, I have no idea what your product does.

But, if you only want to sell it to Linux Programmers, then your video may work just fine! Good Luck with your Project!

 I'm with you in not understanding what the system does. I hear differences in the different music examples, but I don't necessarily prefer one example over another. I guess they don't sound that much different to my ears.

Stephan kept mention "timing" in his description of his system. I'm thinking it might allow you to change tempo without changing pitch. If I'm right, I wonder if it can also change pitch without changing tempo. That might be desirable for the person below that wanted to change the pitch of an orchestra relative to concert A 440.

Stephan, can your system do that sort of thing?

 Dear John,

the concept of audio-timing is neither pitch nor playback speed, it is a different discipline.

Nevertheless my system allows a change in the pitch by setting an offset in the sampling frequency while playback per title, so you could play a song +-127 Hz from 44.1kHz base freq, well basically, although smaller adjustments make more sense.

If one would condition one's hearing to the concept of audio-timing one will definetely find a sweet spot, and that is distinct for everyone, but also distinct for every album and sometimes for a title of an album, because every album has had a different digital transfer to CD and therefor a different internal timing after the production steps, so there will never be one "perfect" setting for all instances of music records, it is about fine-tuning this to your own preferences.

I have just uploaded a new version of my video btw., you may check out the 3 versions of the new 2nd title.

Regards,

Stefan Michael

 Welcome to the Asylum Stephan -

Why not just post your YouTube link so people don't have to search? I searched 'audio' and 'microcomputer' and found dozens of videos that I have no interest in looking through in order to find yours.

Why not put a link to your video here so people can find it immediately?

 Dear Ivan303,


and to everyone else chiming in on potentially false allegations:

let me be crystal clear,

I was never part of the "industry" - if that should mean the audio-related industry,

I am currently not a part of this "industry",

I am not endorsed by anyone of this "industry",

I don't have any own active business at the moment regards this "industry",

and, asking for a donation and for support by showing the invention I have worked on completely on my behalf in my private time for many years is NOT the same as offering a commercial product or a service as a business.

I might have a business plan in my head and I would be pretty naive if I hadn't after all I've exeperienced,

but please - get these facts straight before pointing to moderators or admins, because I find that insulting.

Simply asking me before posting such things might have saved all of our time reading these uneccesary posts.


Regards,

Stefan Michael

 It has gotten to the point where focusing on absolute polarity became more trouble than it was worth......

I've come across inverted recordings, and also recordings in which the performers were mixed on both inverted and non-inverted tracks......

Not to mention, most multi-driver speakers don't have the same absolute polarity on all the drivers...... In fact, a lot of classic JBL speakers have the woofers wired invert absolute phase..... (I've done the "battery test" to bear this out..... A positive potential on the red terminal relative to the black terminal sucks in the woofer on most classic JBL speakers.)

Although I can distinguish absolute polarity with time-aligned or full-range-driver loudspeakers, I have never been able to do so with headphones..... Even headphones costing over a grand......

 Hello AbeCollins,

hello all,


the link of the video before has expired because I had to re-upload the video as the 2nd song had to be taken out,

but I've overlooked a detail in my video editing software when replacing the 2nd song snippets,

so I had to do another conversion and re-upload, I actually went to bed around 5am this morning! :)

It seems to be taking forever putting this together for yt to work as I want it to.

Anyway, I'm glad it is updated, and now the 2nd song are basically 3 variants of a well-known .sid file, where the change in the timing pretty much changes the whole expression of the song, well, under condition one would spot the difference, as these variants are more precise vs the previous Genesis song, so kind of a smaller degree of timing changes, esp. from PRG113 to PRG108.

But rather intriguing due to the way how .sid music is being composed.

The yt channel link below should remain and should be the one to use from now on.

Regards,

Stefan Michael

 Dear Ivan303,


sorry if this felt nasty for you, it wasn't meant to be, I was merely defending my own position here. And even with English being my 2nd language I am trying to be clear in what I say.

No harsh feelings, ok? I know that some forum moderators might believe this is spamming, so I was just overly careful.


Kind regards,

The 92% solution (Polarity Pundit), posted on December 24, 2021 at 12:35:18
geoffkait
 But without a polarity switch forget about it. Personally I think the majority Of CDs are in correct polarity, that there may have been some fear mongering about the issue. The polarity pundit, who I am pretty sure was discredited by Clark Johnson and perhaps others, claimed 92% of CDs were in reverse polarity, which doesn't make sense. I don't find to that me true. Maybe his system was in reverse polarity, wouldn't be surprised, who knows?

 He was the "polarity" guy.....

Ironically, it was he who was most responsible for me no longer being focused on absolute polarity..... I used to discuss this a lot, but George made me discover those "variables" I alluded to..... (I don't think he was correct about the percentage of recordings being inverted..... It would take a huge sample size to get any sort of accurate number.) Unless a system has speakers that don't invert phase for any part of the frequency spectrum (especially speakers with time aligned drivers or speakers with full range drivers), I wouldn't worry too much about the polarity (or mixed polarity) in recordings.

Clark Johnsen, posted on December 28, 2021 at 06:12:17

 Yes, I know, I've interacted with him and of course Clark Johnsen, you know, author of the book on polarity. George developed a huge database of audiophile recordings CDs he claimed were inverted. He believed 92% of CDs were inverted. But when I found some CDs on George's list he claimed were inverted were not inverted I lost confidence in the whole shebang.

The other problem I had with George was his extremely convoluted explanation of why 92% was the magic number. But at least he did listen to a great number of CDs and that's more than most people are willing to do, for sure. Bob Crump demoed inverted/non-inverted CDs for folks at CES circa 2001 since his Blowtorch preamp had a polarity switch. Polarity was quite obvious on that system so I know what inverse polarity means.

However, I don't find too many CD inverted polarity actually and I listen to a lot of CDs. Ditto cassettes. It makes much more sense that George's system for whatever reason was inverted in polarity so all CDs that were actually in correct polarity SOUNDED inverted. It makes more sense that the correct percentage is 8% not 92%.

 Here is my executive summary:
This is an RPI based music player that is claimed to 'improve' musical timing. How is not explained (fair enough to keep IP secret). The music playing software does not use a GUI - all settings/selections are done using a switch box. Some short music selections are presented in the video with different settings, I didn't notice any obvious differences so either I'm am not sensitive to whatever is being done or I need training to appreciate it. Or, maybe, whatever is being done gets lost when played back through YT & Windows audio?
Schiit developed a DSP-based system to re-tune digital music files while keeping the correct timing, though they've deferred releasing this as a product. I wondered if this could be a corollary but there is no mention of DSP in the video so I doubt it. I wonder if digital timing is being changed how that will work with DACs that re-time input data and all the 'de-crapifying' measures employed?

 I met Clark when I was in John Curl and Bob Crump's room at CES showing off my new Sub Hertz Nimbus platform.

I suggested him bring your Brilliant Pebbles into Boston Symphony Hall..... Your business could have taken off like a rocket..... Acousticians and venue operators all over the world could have been knocking at your door to acquire your products...... (Such revelation could have transformed how the audiophile community perceived you and your products.) Unfortunately, this was a missed opportunity.

 Believe it or not my pebbles are in the recording studio owned by George Martin, the one that records symphonies, a beautiful building in London. Brilliant Pebbles was also featured at a big room at London Hifi Show 2003. Clark had my pebbles too for a while. A hard sell but they've done OK.

I suspect Jack Bybee copied them or mimicked them in his last product or two. I had sent John Curl a small bottle a long time ago and he gave the bottle Jack.then there is that other dude who sells pebbles by the score. I spoke with Jack around 2095 on the dodgybsubject of the quantum mechanic behind theIntelligent Chip. I demo'd the pebbles in Golden Sound's room at CES 2005, the year of the Intelligent Chip. I just remembered, Michael Fremer got some I sent but I never heard from him again. Maybe they're in his aquarium. Lol

 I'm not sure I understand what the music player is trying to do, and am not really interested in watching the video, but there are many hardware devices and software applications that can change the pitch of a digital file while maintaining the original tempo. Or change the tempo while maintaining the pitch. Musicians, and wanna be musicians like me, use them all the time. I'll convert a song to the pitch the vocalist wants and save it to practice with. I'll slow it down while learning the song, select specific phrases to work on, etc.

Regards,

Steve
