Thanks for joining! Bigger thanks for the clarification. Don't worry about emkay. His opinions are stated as fact for everyone else. If it doesn't "sound like" 8-bit to him, it is not, and he will do no research (look at the source code) or listen to anyone stating otherwise.

No worries, It's actually my fault. I should write shorter and clearer explanations rather than pages and pages of boring details. :-)

Ciao Antonio and congratulations for your player (and for Planet Golf too).

I have seen the player some days ago on Italian speaking FB groups.

Ciao Philsan, thanks!

Thanks for giving PG a try too. I would love to port it to Atari, and I'm sure it'll happen at some point. I've been drooling over that faster CPU for decades now :-)

It actually sounds forced and muffled. You may listen to the sources of that samples.

 

April 1st, well, the Article shows some frequency waves.... very low at resolution. But it COULD point to 8 bits , if it was just showing a better resolution itself.

You may analyze the picture and see that a lot of data is different and peaks were missing. You may possibly see more differences by a cleaner picture.

 

Hi emkay, Author here.

 

-So, the player is actually 48khz, as obvious from the source code of the player, which is in the article.

 

-It's also 8-bit: it uses Pex 'Mahoney' Tufvesson's technique to play 8 bit digi which, by the way, is only one of the two known techniques to play 8 bit digi on the SID, as clearly stated in the article. Check Mahoney's page for details about the technique I used. The link is in the article.

 

-The picture is fuzzy, but you can click on it, and it zooms out. I thought that was obvious. Anyway, if you do that, you'll notice that there's absolutely no visible difference in the waveforms, and definitely no peaks are missing. The second waveform is different, because it's the differential waveform, but you have to compare the first and the third, as clearly written in the article.

 

-The loud "ssss" sounds in Mazinger demo are indeed there. But that's because they are also in the original. That is the signature way of singing of Ichiro Mizuki: https://www.youtube.com/watch?v=Y8QXVTn77JM

I'm assuming that you have at least a basic knowledge of the theory of Digital Signal Processing, so you will know that lower frequencies and bit resolutions actually kill fricative sounds, don't amplify them. So the sentence "It's much too sharp sounding. Just like only a strip of bits is played", makes absolutely no sense. That's like saying "that picture is too colorful. Just like it's only one bit per pixel".

 

-And of course, about the possibility of the whole thing being an April fool, I wonder how that can be a possibility given that the demos can be downloaded for everyone to run them. As clearly written in the article.

 

One thing you are right about, though: The originals, that are 96Khz 24bit in lossless compression, might sound a tiny bit better than the C64 version, which is 48Khz 8 bit with lossy compression. I would be surprised if that wasn't the case.

But that too is clearly written in the article. :-)

 

A big hello to all the folks here: I'm a HUGE fan of all Atari things!

Take care

Antonio
