To perform the analysis call: |
|---|---|
| 2 |
|
| 3 |
out = getmeasures2(fname,ts); |
| 4 |
ts is an optional input parameter to specify the number of beats per bar |
| 5 |
|
| 6 |
out is a struct with the following data |
| 7 |
|
| 8 |
out.beats - beat times in seconds |
| 9 |
out.measures - bar boundaries in seconds |
| 10 |
out.timesig - estimate of the number of beats per bar (will = ts if specified) |
| 11 |
out.df - the onset detection function |
| 12 |
|
| 13 |
|
| 14 |
The code is set to downsample the audio file to 11025Hz before processing |
| 15 |
This speeds up the calculation of the onset detection function but has |
| 16 |
negligible effect on the output of the beat tracker. |
