Subject: Feature Request: Disable Interpolation

I installed UADE2 but went back almost immediately as there was one thing that crippled it for me. The first thing I'd do with UADE1 was configure the XMMS plugin to not use Interpolation (the thing that makes it sound like you're playing it through a few layers of cotton sheets). Is there any way of turning this off with UADE2? As I can't find any form of configuration for UADE2. So, if it's there, where? and if it isn't then can the ability to turn it on or off be added please.

Thanks,
Ex

Interpolation was not supported in uade1. I suspect that is not related to interpolation but A500 filter model. UADE1 does not have filtering so it's basically A1200 sound model with LED OFF. UADE2 is in A500 mode by default and emulates LED. The basic A1200 sound model is horrible for most songs, although A500 maybe cuts too much high frequencies regardless of LED state.

Try setting &quot;filter a1200&quot; to uade.conf.

Interpolation can also be controlled from that file you wouldn't probably hear the difference between 'none' and 'default'. You can experiment different settings like this:

uade123 --filter=a1200 --interpolator=default songfile
uade123 --filter=a1200 --interpolator=none songfile

Note this is not a problem in uade, but how a real A500 behaves. Still, I think A500 sounds better than A1200 because it cuts those high frequencies. But that's subjective.

If you happened to install uade2 globally, for example under /usr/local, you can do:

mkdir ~/.uade2
cp /usr/local/share/uade2/uade.conf ~/.uade2/

and edit ~/.uade2/uade.conf. XMMS does not need to be restarted after editing. New settings are read on the next song.

Along with Heikki's suggestion, you could use &quot;--force-led 0&quot; to make sure the emulated Amiga Lowpass filter isn't turned on, even the song requests it, to get even further away from the way it would sound on an Amiga...

There's a similar option in uade.conf, btw...

Forcing led off does not make A500 sound very clear. There will stlil be filtering. It always cuts some frequencies.

I thought it as an additional way to revert sound further to uade1 output  :-)

Is there a consensus emerging that the filtering is too steep? (It should match the samplings I've got quite well, though.) There may have been different A500 models with different filtering parameters, so there are reasons to believe that more than one filtering model for A500 might be needed. In this case, though, it's probably just because someone got used to what it used to sound like and doesn't like the new sound. It's a matter of playing with that sound for a while and learning to like it.

I would recommend simply making the --filter=A1200E or filter A1200E more prominent in the manuals, just so that people who find the A500 emulation (with the A500E parameter) is too damp can enjoy the nearly perfect A1200 emulation, which is much brightert. (Due to having sampling noise removed, it won't sound as bright as uade1 was, though.)

not from me. I like it.

But I can imagine if you have no highend soundcard or it supports hardware filtering the a500 filter models + interpolation  might turn chiptunes being muffled or so.

I actually removed UADE2 and went back to UADE1 due to UADE2 basically sounding awful in comparison, but if it is true about the config then setting that would be great. I have been using it as a plugin so I wasn't able to parse commandlines to it before. But yeah, UADE2 by default sounds like listening to  modules with multiple jumpers wrapped around your head and the mod randomly playing some samples louder than others.

So, what exactly do I need to do to make this sound like UADE1 then, i.e. what commands do I need to put in the config file?

Read what I wrote. Try it.

Ah, nevermind, done it now. This is probably in a ReadMe isn't it, damn Gentoo and it's automatedness :P
I'll test it asap.
