# go-waveform

Go module to generate and render waveform images from audio files

Example :

![combined](combined.png)

We can zoom :

![combined2](combined2.png)

# TODO

* doc

* add range

* add segment

* add labels

# Usage :

```go

import (

    // ...

	"github.com/xigh/go-waveform"

	"github.com/xigh/go-wavreader"

)

func main() {

	r, err := os.Open("test-hello.wav")

	if err != nil {

		return err

	}

	defer r.Close()

	

	w0, err := wavreader.New(r)

	if err != nil {

        return err

    }

    

	img := waveform.MinMax(w1, &waveform.Options{

		Width:   1800,

		Height:  400,

		Zoom:    1.7,

		Half:    false,

		MarginL: *margin,

		MarginR: *margin,

		MarginT: *margin,

		MarginB: *margin,

		Front: &color.NRGBA{

			R: 255,

			G: 128,

			B: 0,

			A: 150,

		},

		Back: &color.NRGBA{

			A: 0,

		},

	})

	w, err := os.Create("test-minmax.png")

	if err != nil {

		return err

	}

	defer w.Close()

	err = png.Encode(w, img)

	if err != nil {

		return err

    }

}

```
