STFT Filter Bank. Each channel of an STFT filter bank implements the processing shown in Fig. 9.4. The same processing is shown in the frequency domain in Fig. 9.5. Note that the window transform is complex-conjugated because the window is flipped in the time domain, i.e., when is real [ 264 ]. Figure: One channel of the STFT filter bank ...

Directional Audio Coding (DirAC) is a perceptual method for reproducing spatial audio using existing microphones and surround sound configurations. In the analysis phase, the direction and diffuseness are continuously estimated in frequency bands. This information, together with input signals remapped into a set of virtual microphones corresponding to the …

Audio Filter Banks

Audio Filter Banks. It is well known that the frequency resolution of human hearing decreases with frequency [71,276].As a result, any ``auditory filter bank'' must be a nonuniform filter bank in which the channel bandwidths increase with frequency over most of the spectrum.A classic approximate example is the third-octave filter bank. 11.14 A simpler (cruder) approximation is …

Domain in which filter bank is designed, specified as the comma-separated pair consisting of 'FilterBankDesignDomain' and either "linear" or "warped".Set the filter bank design domain to "linear" to design the bandpass filters in the linear (Hz) domain. Set the filter bank design domain to "warped" to design the bandpass filters in the warped (mel or Bark) domain.
