Analysis methods

From Audio Engineering

There are several forms of Audio Analysis. Basically it means to observe what frequency information contains a audio recording.

[edit] Analysis Technics

• Fourier Analysis and their deviantions:
  • FFT - Fast Fourier Transform;
  • DFT1 is a more sofisticated analysis that uses the derivative signal to have a more accurate frequency analysis;
  • sFFT - sliding FFT is viewing the FFT as a Filter Bank;
• CQT - Constant-Q Transform;
• BQT - Bounded-Q Transform;
• FFB - Fast Filter Bank uses the sFFT butterfly scheme but with higher order filters;
