Delfina flipper at 1200 clockport under AOS 4.0 Classic
« on: September 13, 2011, 07:46:45 PM »
Spent some time trying to get work Delfina flipper connected to Amiga 1200 clockport under AmigaOS 4.0 Classic.

Installed AHI drivers version 6.0 (AudioModes/AHI) from m68k-amigaos-ahidrv
Installed delfina.library 4.16 B48 from http://www.jschoenfeld.com/ (looks like latest)
Installed binary utils (DelfMem from original floppy, DelfInit from aminet).
Installed ahi-handler_os4 from aminet

After some experiments found, that card work only if delfina.library added to compatibility mode (no JIT emulation). Worked more/less stable, right now playing mp3 about 2 hour nonstop.
Without disabling JIT for delfina.library - system hangs in 5-30 seconds after initialization (once i succeed start player very quick and get about 3-5 seconds of audio before it hangs).

(I check about 6-8 versions delfina.library, include some old betas and patched, and looks like latest from site is more stable)

AmigaOS 4 have two emulators - Petunia (JIT), fast and dirty and BlackBox, slow, but accurate.
The bad news (i think that) without JIT delfina works slow.
We have 4 audio modes:
- 16 bit mono
- 16 bit stereo
- HiFi 16 bit mono
- HiFi 16 bit stereo.
And looks like there not enough speed to use some more, than "mono".

I use TuneNet for playing local mp3 and network stream (both 128kbps).
- 16 bit mono - Local: cpu ~70%, no clipping; Network: cpu ~80%, no clipping
- 16 bit stereo - Local: cpu ~95%, almost no clipping; Network: cpu ~95% almost no clipping.
- HiFi 16 bit mono - Local: cpu ~80%, no clipping; Network: cpu ~80% no clipping.
- HiFi 16 bit stereo.- Local: cpu >100%, clipping; Network: cpu >100% clipping.

And even in mono mode there almost nothing that you can do - open any window, move any window, start any program - it always start to clipping.

I use some magazines/music disc, than use AHI, and there same situation, almost always it clipping.

For example paula in "HiFi 14 bit stereo ++ calibrated" plays mp3 with cpu load about ~45% and together i can use Amiga almost as usual, with no sound clipping. And sound quality quite good.
Yes, you can save some cpu by decreasing frequency from default 48kHz to 32-27Khz, but then you lost any sound difference with paula (Delfina - Hifi 16 bit Stereo with 27Khz still eat 85-90% cpu!)
So looks like no reason to install Delfina Flipper for AmigaOS 4

Ideas, comments, suggestions? :)

Latest Delfina.library is 4.17b392 that you can get from Jen's Website here: http://icomp.de/products/delfina_e.htm

It was updated some months ago. I haven't tested it yet under OS4.1 but under OS3.9 it works like a charm on my A4000 mounted on Deneb's clockport.
Thanks for the info, will definitely give a shot soon.

I wonder how I managed to miss it?
Aha! "Support" page show old version (http://icomp.de/home/indexe.htm), only "product" page got new! :) Thank you.

Testing new version.
Good thing - it work without manualy added to "no JIT" list.
Bad thing - looks like it a bit slowly, so it clipping even at "Hifi 16 bit Stereo with 27Khz"! awful!

UPD1: maximun no clipping mode, with new version, that i can run
- "16Bit Stereo @32kHz", CPU ~90-95%,
- "HiFi 16Bit Stereo @16kHz", CPU ~90%,
and do not touch anything, any window - clipping.
UPD2: Yes, Delfina gives a bit cleaner sound, particularly noticeable at high frequencies, but in none of the modes (even in 16bit Stereo @27kHz) does not get 45%CPU, like Paula. And even in this mode it clipping sometime (once in few minutes).

Well, I take my words back.

I tested delfina under AOS3.9 with cpu 040@25 and I want to say that there is so much to slow, that hardly plays 8-14 channel .xm modules on digibooster, to say nothing about .mp3.

I did a few tests, at the request of friends from the local amiga forum, and the results recorded for comparison - http://kawai.spb.ru/files/amiga/sound/

My opinion, after all the tests:
- Under aos3.x need at least a faster processor, that would be used delfina through AHI (my 060@60 is out of order, so that I can not check the speed right now). In my configuration native paula (not trhu ahi) is still faster and better.
Plus delfina has a hardware .mp3 decoder.

- Under os4.x card may well be used for high-quality playback of multi-track modules, magazines, and some cases software .mp3.
Plus delfina has a hardware .mp3 decoder. (I still not tested it under os4.x)

So this card is quite good, but it requires a fast machine that would somehow work.

And it has a built-in mixer. It's not bad, I think to connect paula via mixer, and want to solder midi wavetable card adapter (connect wavetable midi module from an old sound blaster), that would connect to the same.

My Delfina on my A4000 (mounted on Deneb) plays really really nice!
I just use stock Amplifier (updated by BB3) using Delfinampeg.device for decoding MP3 files and output is 16bit Hi-Fi Stereo via AHI using Delfina latest library.

I made a custom Mod mounting some custom audio connectors to the internal input/output connectors which you can check here and here.

In one of the pictures you can see a simultaneous usage of:
- CD Play playing AudioCD,
- Amplifier playing MP3,
- EaglePlayer playing Modules via Paula
- My SammichSID playing through Line-In!

Ofc result was an audio mess (LOL) but everything worked just fine :)

I still haven't tested my Delfina under OS4.1.3 but so far my 99,9% concern is OS3.9 :)

Excuse my ignorance, but why install the 68k AHI package on OS4 when it has it's own PPC native AHI?

Surely you only need to install the 68k delfina.library?

AHI splitted to three archives, user (binaries), drivers, and developers (sources).
AOS4.x has "ahi-powerpc-binaries" already installed, but don't have delfina drivers.
So I get this drivers from "ahi-m68k-drivers" version 6.0 archive, because there no "ahi-powerpc-drives".

Ok, but right now for me interesting how fast can delfina work on 060@50 (in AOS3.9).
Can you say what maximum quality you can get while playing software decoded .mp3 files?
What maximum number of channels in tracker modules, that digibooster can play simultaneously, and ahi quality?

No, you can't play hardware decoded .mp3 thru ahi.
If you play .mp3 in hardware, file data sended directly to delfina, so there no work to ahi.
If you use ahi - you must software decode .mp3 file.

Right now, under AOS4.0, i use delfina.library 4.16 B48, because it's faster, than delfina.library is 4.17 B392. But you must add it to Compatibility mode.

I can't remember the config I used so I will check my configuration once I get back home from work and report back.

If you wanna use software decoding why don't you use AmigAMP that has PowerUP and WarpUP plugins ? That way you can leave the heavy job of MP3 decoding to the PPC CPU which is neat :)

Not every amiga has a powerpc cpu. :)
I'm interested in how increasing the speed of delfina with increasing processor speed. Will be  68060 enough?

I know that... but I saw A1200/clockport and OS4.0 in once sentence, plus I saw some PPC stuffz in your signature alas I advised like that :)

I think that 68060 will suffice but I never tried him alone with MP3's :)

Ok, ok, put .mp3 away. In the end delfina can hardware play it. :)
Let's talk about multichannel tracker modules (8-16-more channels, and 16bit samples).
You can't hardware play it, so it's very interesting, how match channels we can play trhu delfina with high quality audio.

You got me now my friend :)

I have no idea about tracker modules/channels etc since I haven't used my Amiga for music production yet. Sadly... my knowledge in these matters is very limited :(
