wav

A simple Go library for reading PCM WAV audio files.

Usage

import "github.com/djfritz/wav"

w, err := wav.LoadFromFile("audio.wav")
if err != nil {
    // handle error
}

fmt.Println(w.Channels)      // number of channels
fmt.Println(w.Frequency)     // sample rate (e.g., 44100)
fmt.Println(w.BitsPerSample) // e.g., 16
fmt.Println(w.Length())      // duration

Loading from bytes

w, err := wav.Load(data)

Data

The PCM data is arranged as N many channels in the wav.Data field. Each channel has the same number of samples, and is stored as an int regardless of the bits per sample. You will have to scale the data using the BitsPerSample field.
