LibrosaCpp is a c++ implemention of librosa using Eigen

similar with librosa, you can just use a single header librosa.h to compute short-time fourier transform coefficients,mel spectrogram or mfcc
- copy the source directory 'librosa' to your project
- add the source directory to your project include path
- write a few lines of code
#include <librosa/librosa.h> int sr = 16000; int n_fft = 400; int n_hop = 160; std::string window = "hann"; bool center = false; std::string pad_mode = "reflect"; float power = 2.f; int n_mel = 40; int fmin = 80; int fmax = 7600; int n_mfcc = 20; bool norm = true; int type = 2; // compute short-time fourier transform coefficients std::vector<std::vector<std::complex<float>>> X = librosa::Feature::stft(x, n_fft, n_hop, window, center, pad_mode); // compute mel spectrogram std::vector<std::vector<float>> mels = librosa::Feature::melspectrogram(x, sr, n_fft, n_hop, window, center, pad_mode, power,n_mel, fmin, fmax); //compute mfcc std::vector<std::vector<float>> mfcc = librosa::Feature::mfcc(x, sr, n_fft, n_hop, window, center, pad_mode, power, n_mel, fmin, fmax, n_mfcc, norm, type);- other window function
- other dct type
- cepstral filtering
