# aubiotrack(1)

a command line tool to extract musical beats from audio signals

## NAME

**aubiotrack** - a command line tool to extract musical beats from audio signals

## SYNOPSIS

```
aubiotrack source
aubiotrack [[-i] source] [-o sink]
           [-r rate] [-B win] [-H hop]
           [-T time-format]
           [-s sil] [-m]
           [-j] [-N miditap-note] [-V miditap-velo]
           [-v] [-h]
```

## DESCRIPTION

**aubiotrack attempts to detect beats, the time where one would intuitively be** **tapping his foot.**

**When started with an input** *source* **(-i/--input), the detected beats are given** **on the console, in seconds.**

**When started without an input** *source***, or with the jack option (-j/--jack),** **aubiotrack starts in jack mode.**

## OPTIONS

**This program follows the usual GNU command line syntax, with long options** **starting with two dashes (--). A summary of options is included below.**

- **-i, --input *source***

  **Run analysis on this audio file. Most uncompressed and** **compressed are supported, depending on how aubio was built.**

- **-o, --output *sink***

  **Save results in this file. The file will be created on the** **model of the input file. Beats are marked by a short wood-block like sound.**

- **-r, --samplerate *rate***

  **Fetch the input** *source***, resampled at the given** **sampling** *rate***. The** *rate* **should be specified in Hertz as an integer. If 0,** **the sampling** *rate* **of the original** *source* **will be used. Defaults to 0.**

- **-B, --bufsize *win***

  **The size of the buffer to analyze, that is the length** **of the window used for spectral and temporal computations. Defaults to 512.**

- **-H, --hopsize *hop***

  **The number of samples between two consecutive analysis.** **Defaults to 256.**

- **-s, --silence *sil***

  **Set the silence threshold, in dB, under which the pitch** **will not be detected. A value of -20.0 would eliminate most onsets but the** **loudest ones. A value of -90.0 would select all onsets. Defaults to -90.0.**

- **-m, --mix-input**

  **Mix** *source* **signal to the output signal before writing to** *sink***.**

- **-f, --force-overwrite**

  **Overwrite output file if it already exists.**

- **-j, --jack**

  **Use Jack input/output. You will need a Jack connection** **controller to feed aubio some signal and listen to its output.**

- **-N, --*miditap-note***

  **Override note value for MIDI tap. Defaults to 69.**

- **-V, --miditap-velop**

  **Override velocity value for MIDI tap. Defaults to 65.**

- **-T, --timeformat format**

  **Set time format (samples, ms, seconds). Defaults to** **seconds.**

- **-h, --help**

  **Print a short help message and exit.**

- **-v, --verbose**

  **Be verbose.**

## BEAT TRACKING METHODS

**Aubio currently implements one the causal beat tracking algorithm designed by** **Matthew Davies and described in the following articles:**

**Matthew E. P. Davies and Mark D. Plumbley. Causal tempo tracking of audio.** **In Proceedings of the International Symposium on Music Information Retrieval** **(ISMIR), pages 164­169, Barcelona, Spain, 2004.**

**Matthew E. P. Davies, Paul Brossier, and Mark D. Plumbley. Beat tracking** **towards automatic musical accompaniment. In Proceedings of the Audio** **Engineering Society 118th Convention, Barcelona, Spain, May 2005.**
