Detailed Description

Function Documentation

void sig2pow ( EST_FVector &  frame,
float &  power 
)

Calculate the power for a frame of speech. This is defined as

\[power=\frac{1}{n}\sum_{i=1}^{n}a_{i}^2\]

Definition at line 472 of file sigpr_frame.cc.

void sig2rms ( EST_FVector &  frame,
float &  rms_energy 
)

Calculate the root mean square energy for a frame of speech. This is defined as

\[energy=\sqrt{\frac{1}{n}\sum_{i=1}^{n}a_{i}^2}\]
