========

Go package capable of generating waveform images from audio streams.  MIT Licensed.

This library supports any audio streams which the [azul3d/engine/audio](http://azul3d.org/engine/audio)

package is able to decode.  At the time of writing, this includes:

  - WAV

  - FLAC

An example binary called `waveform` is provided which show's the library's usage.

Please see [cmd/waveform/README.md](https://github.com/mdlayher/waveform/blob/master/cmd/waveform/README.md)

for details.

Examples

========

Here are several example images generated using `waveform`.  Enjoy!

Generate a waveform image, and scale it both vertically and horizontally.

```

$ cat ~/Music/02\ -\ Peace\ Of\ Mind.flac | waveform -x 5 -y 2 > ~/waveform.png

```

Apply a foreground and background color, to make things more interesting.

```

cat ~/Music/02\ -\ Peace\ Of\ Mind.flac | waveform -fg=#FF3300 -bg=#0099CC -x 5 -y 2 > ~/waveform_color.png

```

Apply an alternate foreground color, draw using a stripe pattern.

```

cat ~/Music/02\ -\ Peace\ Of\ Mind.flac | waveform -fg=#FF3300 -bg=#0099CC -alt=#FF9933 -fn stripe -x 5 -y 2 > ~/waveform_stripe.png

```

Apply an alternate foreground color, draw using a random fuzz pattern.

```

cat ~/Music/02\ -\ Peace\ Of\ Mind.flac | waveform -fg=#FF3300 -bg=#0099CC -alt=#FF9933 -fn fuzz -x 5 -y 2 > ~/waveform_fuzz.png

Apply a new set of colors, draw using a gradient pattern.

```

cat ~/Music/02\ -\ Peace\ Of\ Mind.flac | waveform -fg=#FF0000 -bg=#00FF00 -alt=#0000FF -fn gradient -x 5 -y 2 > ~/waveform_gradient.png

Apply a checkerboard color set, draw using a checkerboard pattern.

```

cat ~/Music/02\ -\ Peace\ Of\ Mind.flac | waveform -fg=#000000 -bg=#222222 -alt=#FFFFFF -fn checker -x 5 -y 2 > ~/waveform_checker.png
