AF 사용 논문에서는
LPS 1채널
IPD 5 조합 (마이크는 0 ~ 8 까지)
AF 1 타겟
n_fft 512로
7 * 257 = 1799 1-D vector를 입력으로 사용.
=> frame 별 연산
하지만, cRF를 하려면 T가 필요.
Can you provide a training demo
real domain으로 수행하기 위해서 complex 도 2채널로 쪼개서 진행하는데
complex domain으로 해서 STFT, AF 로 실험해볼만 할 것 같다.

## input preprocessing
# NOTE 2022.04.08
# [:T] due to 1 frame mismatch. Maybe because of shift?
# need to check later.
stft = torch.stft(raw,n_fft=1024,center=True)[:,:,:T]
