ippStsFftOrderErr

Many IPP FFT routines use order to represent a transform size of 2^order. An invalid order therefore means the transform length cannot be represented for that API variant.

Check order-to-length conversion carefully; passing the raw sample count where an exponent is expected is a common source of this status.

Check these details

  • Whether the routine expects order or explicit length.
  • The maximum order supported by the data type and transform variant.
  • Scratch-buffer and spec initialization for the same order.
