If 2150 iterations of real-to-complex FFT of size 2048 takes less than 10 seconds, then we may be able to make a high quality real-time phase vocoder (just).

2150 iterations corresponds to 100 seconds of audio non-overlapped at 44.1kHz, so if that takes less than 10 second, then in theory we might be OK.
