Block sampling rate conversion for delay reduction

A new implementation method for sampling rate conversion (SRC) is discussed in this work. Since the proposed method performs sampling rate conversion in a block way via FFT and inverse FFT (IFFT), we call the sampling rate conversion in this case the block sampling rate conversion (BSRC). The proposed method can reduce the additional input-output delay resulted from the use of FFT and trade-off it against the computational complexity more easily, compared with other FFT-based approaches
