Re: [Linuxsampler-devel] SFZ engine Polyphony Opcodes

 I thought I mentioned that somewhere in the thread. I only use uncompressed Wav files to avoid any unnecessary encoding. Most of my samples are 24bit 44.1khz or 24bit 48khz and they are all Wav. 

Regarding Jacek's comment, I am recompiling LS with different configurations and it seems the behavior of --enable-preload-samples= argument is a little bit unpredictable (well, to me). The default value is 32768, which in practice (for 180 max voice) it loads 730MB out of a 8.5GB sample library. 

I recompiled it with setting it 10 times larger, --enable-preload-samples=327680 and it loaded 2.6 GB. Recompiled it with 100 times larger and it loaded 5.3GB.  Recompiled it with 1000 time larger value of 32768000 and the amount of preloaded samples did not go anything above 5.3GB

Side note------------

I saw some unusual behavior here as well. Surprisingly, when I increased the "max voices" LS can actually by far surpass the size of the library. For the 8.5GB sample library, LS could require 12GB if I increase the max voices. I only did this for testing (no other reasons to apply such a setting). it seems each stream can also occur independent of pre-loaded samples or at least its allocated RAM memory is independent of pre-loaded sample? I'm not sure. I thought the streams should take the preloaded data into account.

File format of samples being used (wav, flac, ogg vorbis)?
