[Linuxsampler-devel] New sample engine (and editor too)

[Mauricio Kanada]

Hello developers.

I was thinking in a new sample format based on spectrum and not on waveform. The idea is create samples that sounds good without the need of thousands of samples.
Imagine a piano library with only 5 velocity layers stored in spectra format (maybe in mdct format) and the engine blend the spectrum at run time. Casio has this technology and name it as 'Multi-Dimensional Morphing'. Kontakt name it as AET (Authentic Expression Technology), but as I know, it is at edition time, not at runtime.

Now, imagine that this technology can be used not only to piano libraries, but for any type of sound.
I think that this technology can be groundbreaking in the samplers market. With good editor + script toolset, anyone can create your own 'instrument model'.

What do you think about?

Thanks

Well, this idea is not new and is already used in products for years. It was
also discussed here couple years ago when we started to work on additional
sampler engines/formats. Keep in mind that performing things in the frequency
domain can be quite expensive. That's why it is mostly still more effective
overall (for the musician) to play with a huge set of samples in the signal
domain instead.

And yes, sure would be nice to have, however so far simply nobody has yet
started working on this with LinuxSampler. Since this is essentially a spare
time project for all of us, it is all a matter of personal priorities.
