Disk-buffered (large) Fourier transform.
Output windows will have a complex size of (size + padding).nextPowerOfTwo
- Value parameters:
- dir
the direction is
1for forward and-1for backward transform. other numbers will do funny things.- in
input signal to transform. This must be complex (Re, Im interleaved)
- mem
the amount of frames (chunk size) to buffer in memory. this should be a power of two.
- padding
the (complex) zero-padding size for each window
- size
the (complex) window size
- Companion:
- object
