# aubiomfcc(1)

a command line tool to compute Mel-Frequency Cepstrum Coefficients

## NAME

**aubiomfcc** - a command line tool to compute Mel-Frequency Cepstrum Coefficients

## SYNOPSIS

```
aubiomfcc source
aubiomfcc [[-i] source]
          [-r rate] [-B win] [-H hop]
          [-T time-format]
          [-v] [-h]
```

## DESCRIPTION

**aubiomfcc compute the Mel-Frequency Cepstrum Coefficients (MFCC).**

**MFCCs are coefficients that make up for the mel-frequency spectrum, a** **representation of the short-term power spectrum of a sound. By default, 13** **coefficients are computed using 40 filters.**

**When started with an input** *source* **(-i/--input), the coefficients are given on** **the console, prefixed by their timestamps in seconds.**

## 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.**

- **-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.**

- **-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.**

## REFERENCES

**Using the default parameters, the filter coefficients will be computed** **according to Malcolm Slaney's Auditory Toolbox, available at the following** **url:**
