Go - int16 slice to byte slice

Question

I'm writing a Go program that interfaces with libalsa. I have my PCM data stored in a []int16 slice, but to call libalsa I need that stored in a []byte slice.

How do I convert a []int16 slice to []byte to accomplish this?

Answer 1

You could try this:

package main

import "fmt"
import "bytes"
import "encoding/binary"

func main() {
    nums := [6]int16{2, 3, 5, 7, 11, 13}
    buf := new(bytes.Buffer)
    err := binary.Write(buf, binary.LittleEndian, nums)
    if(err==nil) {
        fmt.Printf("% x", buf.Bytes()) 
    }

}
