Browser based YM jukebox

[LynXX]

Hi all,

I've been working on a web-browser based YM jukebox and I finally have a first version available. You can find it here:

https://nguillaumin.github.io/ym-jukebox/

It's pretty basic for now and lacking important features (search for example), but it's a start. At least now you can easily listen to YM tunes on your computer or mobile device!

I realize the YM format is kind of obsolete and has been superseded by SNDH, but there's still a huge library of tunes out there, and it was easier to port it to Javascript than a SNDH player, so I went for it.

I put everything on GitHub if you want to contribute, either on the app itself or helping organizing the YM library: https://github.com/nguillaumin/ym-jukebox

To help with library organization I also wrote a little tool to edit YM metadata and various other things: https://github.com/nguillaumin/ymtool It's still in its infancy and only supports the YM5 file format for now. It also doesn't unpack LHA-packed YM files because I couldnt' find a LHA depacker that worked in Go (the language the tool is written in) and I also couldn't find information about the LHA file format to write one myself (if anyone has any technical information about the LHA/LZH format, I'd be interested!).

Feedback is welcome, on this forum or via GitHub issues. I hope you enjoy it!

Thanks!

Nico

Hey there,

I think some people did this before, but nice to see another go at it!

Other browser based YM players :
- https://github.com/photonstorm/Flod/tree/master/Flym (AS)
- https://github.com/photonstorm/phaser-p ... r/YM/YM.js (CODEF based it seems)
Also some did a SNDH player :
- https://github.com/bobuss/sndh-player
- https://github.com/photonstorm/sc68-2.2.1
(those two are emscripten based, so not "true" JS code one may say )

Nice Player LynXX.

It's a good way to quickly go through lots of YMs which is very useful on a mobile phone. It's fine on Chrome and Firefox but it doesn't seem to work on IE11. It simply displays Loading...

JS error is:
abort(No WebAssembly support found. Build with -s WASM=0 to target JavaScript instead.) at Error: 0 at O
libym.js line 1586

Thanks!

I knew about the Emscripten port of sc68 actually, but I didn't know about the other links, I'll check them out. Mine is also an Emscripten port of the Leonard YM library.

For IE11 I'm not surprised, it's just too old, it would be too much effort to support it. Event Microsoft doesn't want you to use it But I will try to at least handle the error more gracefully.

You could use my recordings at http://sndhrecord.atari.org/ (all recorded from real STE)

Hi Adam,

I've searched a site like yours for ages without success.
That's exactly what I was looking for.
Thanks a lot.
Couldn't you let me know before ?

Thanks also to DMA and Lynxx for the online players.

Awesome work Nico. This is do much fun to use on my phone. Thanks for this!

[LaurentS]

I really enjoy the tool. That's so nice.
Would it be possible to add a random play option, so that I could listen to music for hours without having to click to the next one ?

Great idea! I'll look into it, shouldn't be too hard...

Hi

Nice interface for music ; but while listening to some of them, I noticed that the speed is not correct, it plays too fast, as if played at 60 Hz instead of 50 Hz.
For example, listen to "Beatnick" by Mad Max : it really plays too fast and the digidrums are really wrong.
"Wings Of Death 0 - loading" is also too fast, but "WingsLoading" (which should be the same) plays insanely too fast

Maybe it's a bug in your player or maybe it depends on the browser, I'm using linux + firefox, but it should be possible to get a correct 1/50 sec between each YM frames (most of he songs should be played at 50 Hz, songs that were composed to be played at 60 Hz are rare)

I added a button in the playlist screen to enqueue 100 random songs (can be clicked multiple times). The random selection is pretty naive and may yield duplicates for now.

And yeah there's something wrong with the playback. I don't think it's faster, but the pitch is different and there's something wrong with the digidrums indeed. Thanks for providing that example. At a glance I couldn't find the reason but I'll investigate...
