LibrosaCpp

LibrosaCpp is a c++ implemention of librosa using Eigen

About

similar with Eigen, you can just use a single header librosa.h to compute short-time fourier transform coefficients or mel spectrogram

Usage

  1. copy the source directory 'LibrosaCpp' to your project
  2. add the source directory to your project include path
  3. write a few lines of code
#include <LibrosaCpp/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;
  // 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);

TODO

  • other window function
  • compute MFCC
