# go-waveform
Go module to generate and render waveform images from audio files
Example :
We can zoom :
# 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
}
}
```
