Low Latency Audio Pitch Shifting in the Frequency Domain

摘要：

This paper presents a low latency pitch shifting algorithm based on the Short-Time Fourier Transform (STFT). Unlike existing STFT-based implementations of pitch shifting, the presented algorithm is more robust to reductions of the Fourier transform size. As a result, it achieves latencies as low as 12ms and still produces good quality, whereas other algorithms are performing much worse with similar low latency constraints. The presented algorithm also provides an alternate way of mitigating the well-known phasiness problem of the phase vocoder.
