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
