Re: [fluid-dev] Supported Wave/Flac format other than SF2

[BCA @ Free-Artists]

In certain points, I don't understand the initial posting. One thing is 
clear to me - he doesn't want to construct a soundfonts ("Going by SF2 
is going to be hard for developer to implement new soundfont"). It 
appears he wants just to import sample files on button press, and start 
playing them. That means for FS, the sample player shall construct the 
soundfonts.

E. g., I'm not quite sure why *wave* support shall be added to 
FluidSynth. SF2 is based on wave data files. Nowadays, we're able to 
import 24bit wave samples into the soundfonts, so the sound quality as 
such cannot be the reason for that request. So that is an obvious 
misinterpretation.

I can understand the request for flac format, since it is lossless 
(compared with wave), and saves about the half of hard disk space. It 
might even be, once in future, FLAC will replace wave (if the CD 
industry allows for this ;-).

FluidSynth is soundfonts player only, so in regards of FS, a request can 
be only, to enable soundfonts contruction from native flac sample files 
(IIRC Swami has planned so for future). FluidSynth as such could be made 
fit for reading such soundfonts, indeed. But in that case, it would be 
at least frome equivalent interest (in my eyes), to support soundfonts 
files based on Ogg Vorbis or a similar HQ compression format. This would 
be a real improvement, since the soundfonts could be reduced 
impressively in file size, while keeping HQ sound.

David, does FS support playing soundfonts in a bit-ness higher than 
16-bit? Another question in regards of FS, would be support for up to 
96-bit soundfonts.

I've never seen any soundfonts where the constructor has has fully 
reached the sf2 format's potential, and my point of view is that 
soundfonts are future safe.
