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;
