| 13 | OPTIONS |
|---|
| 14 | |
|---|
| 15 | This program follows the usual GNU command line syntax, with long options |
|---|
| 16 | starting with two dashes (--). A summary of options is included below. |
|---|
| 17 | |
|---|
| 18 | -i, --input source Run analysis on this audio file. Most uncompressed and |
|---|
| 19 | compressed are supported, depending on how aubio was built. |
|---|
| 20 | |
|---|
| 21 | -r, --samplerate rate Fetch the input source, resampled at the given |
|---|
| [c18981e] | 22 | sampling rate. The rate should be specified in Hertz as an integer. If set |
|---|
| 23 | to 0, the sampling rate of the original source will be used. Defaults to 0. |
|---|
| [403e9dd] | 24 | |
|---|
| 25 | -B, --bufsize win The size of the buffer to analyze, that is the length |
|---|
| 26 | of the window used for spectral and temporal computations. Defaults to 512. |
|---|
| 27 | |
|---|
| 28 | -H, --hopsize hop The number of samples between two consecutive analysis. |
|---|
| 29 | Defaults to 256. |
|---|
| 30 | |
|---|
| 31 | -O, --onset method The onset detection method to use. See ONSET METHODS |
|---|
| 32 | below. Defaults to 'default'. |
|---|
| 33 | |
|---|
| 34 | -b, --beat Use beat locations instead of onset locations. |
|---|
| 35 | |
|---|
| 36 | -t, --onset-threshold thres Set the threshold value for the onset peak |
|---|
| [cd2cbc4] | 37 | picking. Values are typically in the range [0.001, 0.900]. Lower threshold |
|---|
| 38 | values imply more onsets detected. Increasing this threshold should reduce |
|---|
| 39 | the number of incorrect detections. Defaults to 0.3. |
|---|
| [403e9dd] | 40 | |
|---|
| 41 | -c, --cut Cut input sound file at detected labels. A new sound files for |
|---|
| [c18981e] | 42 | each slice will be created in the current directory. |
|---|
| 43 | |
|---|
| 44 | -o, --output directory Specify the directory path where slices of the |
|---|
| 45 | original source should be created. |
|---|
| 46 | |
|---|
| 47 | --cut-until-nsamples n How many extra samples should be added at the end of |
|---|
| 48 | each slice (default 0). |
|---|
| 49 | |
|---|
| 50 | --cut-until-nslices n How many extra slices should be added at the end of |
|---|
| 51 | each slice (default 0). |
|---|
| [403e9dd] | 52 | |
|---|
| 53 | -h, --help Print a short help message and exit. |
|---|
| 54 | |
|---|
| 55 | -v, --verbose Be verbose. |
|---|
| 56 | |
|---|
| 57 | -q, --quiet Be quiet. |
|---|
