# go711

This is a simple G711 codec implementation in Go. 

It supports both A-law (PCMA )and μ-law (PCMU) encoding and decoding.

## Installation

```bash

go get github.com/shenjinti/go711

```

## Usage Example

```go

func TestPCMA(t *testing.T) {

	pcmBytes := []byte{0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07}

	// Encode PCM bytes to A-law bytes

	alawBytes, err := EncodePCMA(pcmBytes)

	if err != nil {

		t.Fatal(err)

	}

	if len(alawBytes) != 4 {

		t.Fatalf("a-law bytes length is not 4: %d", len(alawBytes))

	}

	// Decode A-law bytes to PCM bytes

	pcmBytes, err = DecodePCMA(alawBytes)

	if err != nil {

		t.Fatal(err)

	}

	if len(pcmBytes) != 8 {

		t.Fatal("PCM bytes length is not 8", len(pcmBytes))

	}

}

```
