1. <SimpleLPC.py> LPC analysis by one thread
2. <ThreadBasedLPC.py> LPC analysis by multi-thread
3. <ProcessBasedLPC.py> LPC analysis by multi-processing
4. <CmpMCEP2MFCC.py> the comparison of MFCCs and MCEPs
5. <IIRFilters.py> Biquad IIR Filters: Peak, Notch, High-Pass, Low-Pass, Band-Pass, All-Pass, High-Shelf, Low-Shelf (Thanks: https://webaudio.github.io/Audio-EQ-Cookbook/audio-eq-cookbook.html)
6. <Invfreqz.py> the Python implemention of "invfreqz" in Matlab, fix the error in https://github.com/awesomebytes/parametric_modeling and use “lstsq” to return the least-squares solution to singular values.
