Re: [Sursound] noise occur when using fft + overlap and adding

Hi, This problem might be related several issues: (1) did you use window when overlapping-add; (2) HRTF is a complex value, rather than a real value which is normally used in speech enhancement processing. Multiplication with a complex value in the frequency domain might one of reasons which cause

[Sursound] noise occur when using fft + overlap and adding

I have a question here: I want convolving a music signal with head-related impulse response (HRIR), and use the FFF + voerlap and adding method. I transfer a frame signal into frequency domain and multiply the HRTF (HRIR in the frequency domain). The length of HRIR is 512, and the FFT lenght is 512
