Digitunes an Atari 130 XE program

Recommended Posts

The Van Halen cover of, "You Really Got Me," was also a standalone demo with a longer runtime, from what I recall.

YOGI of Jellystone Park... made this compilation of digitunes. It is not a manufactured disk or product. Fun stuff in the BBS days.

Hey Doc: How did Yogi do this? I want to digitize some of my 600 vinyl record collection and have not found a way of taking 8 bit samples down to 4 bit samples.

You don't do that on Atari, nowadays.

 

Instead, you first encode in .WAV or .MP3 (for example), then encode to .PDM format, (pulse or wave? density, with Xuel's web-browser encoder) and then playback at MUCH higher quality than anything from Yogi's samples, all via AVG-cart .PDM player, for instance.

 

 

You will be blown away with the difference in quality...

They sound like they might be 2-bit samples.  You can double the length without huge quality loss vs 4-bit.

 

In the 80s it was mostly novelty value - but yeah, as mentioned we have better options for doing quality audio these days that you'd actually play more than once.

As you say, total novelty value, no one in their right mind would want to listen full tracks in that quality, even the PDM stuff, while excellent is not what I'd listen to, visual and audio stuff I want in the best possible format. It is nice to see our old machines doing things we thought were not really possible, but purely bite size entertainment..

Yes, we do have better sampling options today. Therefore most of these old samples are only 16k in length and can be loaded quickly from diskette (and here we also have better options today).

 

Regarding PDM, I think I also have better options available today - better than any 8Bit or 16Bit computer could do.

Yes I digitize music in full lengths of the record(s) in surround sound , I have ways of making the tunes sound *almost* as good as vinyl, and it takes a while, but if you really want to listen to good sampled music, I have a section on my BBS for just that.... Have not been doing too much of encoding into the Atari but have been encoding from the Atari. By the way the section on my BBS is for Public Domain files but I take them and re-encode them at a higher rate so that they sound better. I will of course leave a short 30 second sample that is done on my studio to let you hear the quality of what I get. PS: I use a Teak AN-60 Noise Reduction unit in between my amplifier and the tape deck or record player. The reason I am posting this is that IF someone has the stuff to set this up on an Atari computer, you have to start with very high quality samples, I have given you one. I would like to see this being played back on an Atari 130 XE without any special hardware. Can anyone do this?

What is the history of Digitunes? Is it posted anywhere? The 80s music sure represents what was current in popular music at the time ;-) 

 

I did a playback/editor program called The Vigitizer back in the 80s. I have been resurrecting it (currently have it building from source using ca65).

Yep, where we can get a copy of that "digitunes". I tried searching for Yogi collection, Jellystone, etc and I could not find it.

Edit: I think I found it in the tnfs server christfollowersbbs.ca under "Music" folder, but it did not work for me

I have it here .... it is is on one of my disks....Digitize-Tune.atr

 

That seems to be the data files, but not the app shown in the youtube video in the first post of this thread... Did I miss something?

It also cannot be run in Altirra :( :

It seems to be an old version of SpartDOS.

However if you mount the disk, but not boot from it, you can run the MENU program as well as a one of the sampled songs which was done as a .BIN application rather than a raw .MUS file.

I didn't find the player type app shown in the initial post on the ATR.

That file that I sent up works, you have to run it in Basic , give it a try it has the player built into it

For some weird reason it works in Altirra, but not in real hardware using Fujinet.

I will try with a real floppy disk and real drive.

BTW, does anyone have an idea of how this music was digitized back in the day? I mean, from tapes or LP disc to an Atari computer?

A microphone connected to the paddle port via a simple circuit...

 

You'd then use an app on the Atari that would sample the circuit to a buffer in memory for playback or saving to disk.

 

Here is a shot of the app I'd done...

Will this circuit board also do the trick, it should be delivered today...
