CD-DA Audio in Jo is broken...?

(1/3) > >>

ponut64:
I'll just ask anyone here to check the "Audio" demo included in Jo engine. ATM it doesn't work.

Further, Bizhawk and Yabause refuse to load CD files that include mp3 or WAV files. Only SSF loads it, and even then it does not play the music file.
Trying to include the audio files the way Rockin' B says to also doesn't make them 'happy'.
There's got to be some way to get "CD-DA" included in an iso file, right?

I could fathom a workaround to that if we had SGL CD functions, but we don't. And given Jo Engines handling of the CD audio files is very low-level, it seems fool-proof to me.
I'm also not sure how SBL expects you to playback CD-DA.(/e: Oh, CD-XA / ADPCM .. which doesn't really help me!)
I just wonder if it is like this for anyone else.

XL2:
It's using SBL in fact, which has the source code.
It works fine for me, but I haven't tried it on the latest Jo Engine version.
Check my old fps demo for cd audio examples.
I will try to share my own take on audio (using tones for sfx and SBL CDDA audio functions ) in a couple of weeks.

ponut64:
Now I'm wondering how strict the documentation is on "ADPCM".

Like, for example, will VOX work...
I don't really think I need to wonder since converters from AIFF to Sega ADPCM exist (in Mac..) but maybe I can try and feed it to the system and see what it thinks?
(Given the complete and total lack of header data, ... nah, setting up Basilisk 2 wasn't that hard)
Not anytime soon, though.

SaturnTeam:
I just tried it, yesterday. I am using the newest engine version. I couldn't get it to work with any of the emulators by clicking on included launch files in the demo. What I ended up doing was opening Yabause and manually opening the sl_coff ISO. This will successfully get the file open. However, only the sound effect will play. The CD audio is unresponsive. I have read somewhere that it should work normally when burned to a CD and used with Pseudo Saturn Kai, which is what I use on my Saturn.

ponut64:
Yes, that should work. If you burn from the CUE file which will include the music file (included from the CUE file) into the CD.
The problem is I can't debug anything without it being able to load properly in an emulator (*without burning a disc). So with that I am going to switch to 22 (maybe even 11) KHz ADPCM sound instead. The features for ADPCM are probably better suited to what I want to do, anyway.

Thanks for the confirmation.
