A Simple MFCC Feature Extractor using C++ STL and C++11
Features
- Takes PCM Wave input and outputs MFCCs as comma separated floating point values, each line representing a frame.
- Supports batch extraction through list input and output.
- Command line control for window length, frame shift, sampling rate, number of cepstra and filterbank cutoff frequencies.
- Computes MFCCs through pre-emphasis, Hamming window, FFT, power spectrum, equal height log-Mel filterbank followed by discrete cosine transform.
Compilation
g++ -std=c++11 -O3 compute-mfcc.cc -o compute-mfcc
