Additional Code/Dependencies

  1. func_envs.py - This is the python file which contains companion functions to do the following -

    1. Extract Envelopes - ceps_envelope(), lpc_envelope(), calc_true_envelope(), calc_true_envelope_spectral()
    2. Miscallaneous helper functions, Coefficient Conversions (LPC <-> CC <-> LSF) etc

  2. models - SMSTools. Code to perform Sinusoidal, Harmonic, Residual analysis

  3. morphing.py - Functions to morph two audio by linearly interpolating in the appropriate space (lpc, cc, lsf, spectrum etc.)

There is also a Jupyter notebook TAE_demo.ipynb which demonstrates the usage of the various envelope extraction functions.
