ah, the "smpl" chunk ... probably that stuff. i've never actually heard of
samplers using this ;) interesting ....

The most common formats for "loops defi=

s to wav), such as REX, and proprietary.
The WAV spec does include the concept of a playlist, consisting of cue =
points and lengths. By themselves, these don't really define "loop=
s" in a way that is generally going to be clear to the user.
libsndfile can definitely read these from the file, but i'm not sur=
e what an app would do with them. providing a sample with a loop point(s) d=
efined would be good.

Hey fellas!I notice that no Linux samplers seem to support wa=
v file loop points. All Windows DAWs that I have used s=
upport the format and there are a lot of samples out there with perfect loop points which is very useful.

I have no idea whether this is part of the spec or not but these loop=

points have been used for more than 15 years, that's for sure, since=

some of these sample collections have been around during tracking days. I
did find something on loops here: http://www.sonicspot.com/g=

But I think you, devs, know better than me anyway.I
think it would be great if LMMS, samplers like Petri-Foo would support=20
this, as this adds a lot of functionality. Many sample collections=20
provide perfect loops and it is tiresome to have to try to rem=
ake it by hand each time, while in some software it is simply impossible at=
all.
What do you think?ps: I can provide you with a sample example w=
ith loop points
