| 12 | USAGE |
||
| 13 | |||
| 14 | If your system can provide frequency-domain data (e.g. by performing FFT on the |
||
| 15 | input audio), then to perform onset detection you only need onsetsds.h and |
||
| 16 | onsetsds.c. These need no additional libraries beyond the standard C libraries. |
||
| 17 | |||
| 18 | If you aren't already doing the FFT then you can also use onsetsdshelpers.c |
||
| 19 | and onsetsdshelpers.h, which can process raw audio, from a buffer or from a |
||
| 20 | file. These require two additional libraries: |
||
| 21 | |||
| 22 | * libsndfile - I used version 1.0.17 |
||
| 23 | http://www.meganerd.com/libsndfile |
||
| 24 | |||
| 25 | * FFTW 3 (floating-point version) - I used version 3.1.2 |
