| 14 | DESCRIPTION |
|---|
| 15 | |
|---|
| 16 | aubionotes attempts to detect notes by looking for note onsets and pitches. |
|---|
| 17 | Consecutive events are segmented using onset detection, while a fundamental |
|---|
| 18 | frequency extraction algorithm determines their pitch. |
|---|
| 19 | |
|---|
| 20 | When started with an input source (-i/--input), the detected notes are |
|---|
| 21 | printed on standard output, in seconds and midi note number. |
|---|
| 22 | |
|---|
| 23 | When started without an input source, or with the jack option (-j/--jack), |
|---|
| 24 | aubionotes starts in jack mode. |
|---|
| 25 | |
|---|
| 26 | OPTIONS |
|---|
| 27 | |
|---|
| 28 | This program follows the usual GNU command line syntax, with long options |
|---|
| 29 | starting with two dashes (--). A summary of options is included below. |
|---|
| 30 | |
|---|
| 31 | -i, --input source Run analysis on this audio file. Most uncompressed and |
|---|
| 32 | compressed are supported, depending on how aubio was built. |
|---|
| 33 | |
|---|
| 34 | -r, --samplerate rate Fetch the input source, resampled at the given |
|---|
| 35 | sampling rate. The rate should be specified in Hertz as an integer. If 0, |
|---|
| 36 | the sampling rate of the original source will be used. Defaults to 0. |
|---|
| 37 | |
|---|
| 38 | -B, --bufsize win The size of the buffer to analyze, that is the length |
|---|
| 39 | of the window used for spectral and temporal computations. Defaults to 512. |
|---|
| 40 | |
|---|
| 41 | -H, --hopsize hop The number of samples between two consecutive analysis. |
|---|
| 42 | Defaults to 256. |
|---|
| 43 | |
|---|
| 44 | -O, --onset method The onset detection method to use. See ONSET METHODS |
|---|
| 45 | below. Defaults to 'default'. |
|---|
| 46 | |
|---|
| 47 | -t, --onset-threshold thres Set the threshold value for the onset peak |
|---|
| 48 | picking. Typical values are typically within 0.001 and 0.900. Defaults to |
|---|
| 49 | 0.1. Lower threshold values imply more onsets detected. Try 0.5 in case of |
|---|
| 50 | over-detections. Defaults to 0.3. |
|---|
| 51 | |
|---|
| 52 | -p, --pitch method The pitch detection method to use. See PITCH METHODS |
|---|
| 53 | below. Defaults to 'default'. |
|---|
| 54 | |
|---|
| 55 | -u, --pitch-unit unit The unit to be used to print frequencies. Possible |
|---|
| 56 | values include midi, bin, cent, and Hz. Defaults to 'Hz'. |
|---|
| 57 | |
|---|
| 58 | -l, --pitch-tolerance thres Set the tolerance for the pitch detection |
|---|
| 59 | algorithm. Typical values range between 0.2 and 0.9. Pitch candidates found |
|---|
| 60 | with a confidence less than this threshold will not be selected. The higher |
|---|
| 61 | the threshold, the more confidence in the candidates. Defaults to unset. |
|---|
| 62 | |
|---|
| 63 | -s, --silence sil Set the silence threshold, in dB, under which the pitch |
|---|
| 64 | will not be detected. A value of -20.0 would eliminate most onsets but the |
|---|
| 65 | loudest ones. A value of -90.0 would select all onsets. Defaults to -90.0. |
|---|
| 66 | |
|---|
| 67 | -j, --jack Use Jack input/output. You will need a Jack connection |
|---|
| 68 | controller to feed aubio some signal and listen to its output. |
|---|
| 69 | |
|---|
| 70 | -h, --help Print a short help message and exit. |
|---|
| 71 | |
|---|
| 72 | -v, --verbose Be verbose. |
|---|
| 73 | |
|---|
| 74 | ONSET METHODS |
