I have streams of samples with irregular sampling rates, so they look like [(Time, SampleVal)]. In practice, this means [(Double, Double)].
Maybe I have already mentioned my eventlist package on Hackage which supports such resampling operations - but is based on lists. http://hackage.haskell.org/cgi-bin/hackage-scripts/package/event-list
Ah, I had seen event-list and even downloaded and read parts of it, but it was hard for me to figure out what was going on and how to actually use it based on the scattered comments in the source.
I commented only non-trivial parts, because I thought it is clear, that 'mapTime' is a 'map' on the time stamps and so on.
Apparently there are absolute and relative time variants, but within that there are further "body" and "time" variants, and they're built on a similarly sparsely documented alternating list library. Are there some simple examples of its use out there?
There are all four variants of whether a list starts and ends with a time or a data body. The 'midi' package uses 'event-list'.
Unfortunately, storable vector, unlike ByteString, doesn't export 'create' and whatnot so I have to keep a locally patched version of it.
Well, it does export 'create': http://hackage.haskell.org/packages/archive/storablevector/0.1.2.2/doc/html/... However in my applications I could use the safe 'unfoldrN' in most cases.
