以下几个声音处理方面的术语如何翻译
Pre-Emphasis (预加重)
The following FIR pre-emphasis filter is applied to the input waveform:
a is provided by the user or set to the default value. If a = 0, then this step is skipped. In addition, the appropriate sample of the input is stored as a history value for use during the next round of processing.
The remaining operations are done on a frame basis.
Windowing (加窗)
The frame is multiplied by the following Hamming window:
Power Spectrum
The power spectrum of the frame is computed by performing a DFT of length specified by the user, and then
computing its magnitude squared.
Mel Spectrum
The mel spectrum of the power spectrum is computed by multiplying the power spectrum by each of the of the
triangular mel weighting filters (see section 5) and integrating the result.
Mel Cepstrum
A DCT is applied to the natural logarithm of the mel spectrum to obtain the mel cepstrum:
