currently i'm working on stuff that looks something like this:
1 read soundfile from disk in blocks of N samples (IOCArray, hsndfile
package)
2 convert to CArray with unsafeFreeze (simple O(1) cast, carray package)
3 perform FFT (CArray, fftw package)
4 convert to UArr (uvector package)
5 do some stuff with vectors
i'd like to minimize copying, and since the FFT returns a new array
anyway, the only copying conversion is the one between CArray and
UArr in step 4. the approach i've been following is defining a
`stream' conversion for CArray, hoping that subsequent carray
accesses will be fused with uvector operations without the need for
allocating a vector in between. does that make sense? could this be a
general strategy for avoiding copying at the boundary between the
various array libraries?
thanks,
<sk>
