class dsp::FftComplexQ31
  : public dsp::Fft< arm_cfft_instance_q31, SignalComplexQ31 >

The source data for an FFT transform should match the number of samples the FFT computes. The destination should be the number of samples times two.

When performing an inverse, FFT the source data is the number of samples times two and the destination matches the number of samples.
