go-waveform
Golang project for the purpose of practicing, understanding golang and audio file format.
Usage
Requirements
Go 1.11 (Go Modules)
Cli
Generate waveform image via CLI
GO111MODULE=on make
./bin/go-waveform -t dark -r 1000 -f png example/violin.wav
open example/violin-L.png
open example/violin-R.png
Import as package
Import as package,
import "github.com/cettoana/go-waveform"
and decode wav audio file
w := waveform.DecodeWav(wavFileBytes)
fmt.Println(w.BitsPerSample)
data, _ := w.GetData()
if stereoData, ok := data.(*waveform.StereoData); ok {
fmt.Println(stereoData.RSample)
fmt.Println(stereoData.LSample)
} else if monoData, ok := data.(*waveform.MonoData); ok {
fmt.Println(monoData.Sample)
}
