 6 | > promise-based wav decoder
 7 | 
 8 | ## Installation
 9 | 
10 | ```
11 | $ npm install wav-decoder
12 | ```
13 | 
14 | ## API
15 | 
16 | - `decode(src: ArrayBuffer, [opts: object]): Promise<AudioData>`
17 |   - if provide an instance of `Buffer`, it is converted to `ArrayBuffer` like `Uint8Array.from(src).buffer` implicitly.
18 |   - `opts.symmetric` decode to symmetrical values (see [#14](https://github.com/mohayonao/wav-decoder/issues/14))
19 | - `decode.sync(src: ArrayBuffer, [opts: object]): AudioData`
20 |   - synchronous version
21 | 
22 | ##### Returns
23 | 
24 | ```js
25 | interface AudioData {
26 |   sampleRate: number;
27 |   channelData: Float32Array[];
28 | }
29 | ```
30 | 
31 | ## Usage
32 | 
33 | ```js
34 | const fs = require("fs");
35 | const WavDecoder = require("wav-decoder");
36 | 
37 | const readFile = (filepath) => {
38 |   return new Promise((resolve, reject) => {
39 |     fs.readFile(filepath, (err, buffer) => {
40 |       if (err) {
41 |         return reject(err);
42 |       }
43 |       return resolve(buffer);
44 |     });
45 |   });
46 | };
47 | 
48 | readFile("foobar.wav").then((buffer) => {
49 |   return WavDecoder.decode(buffer);
50 | }).then(function(audioData) {
51 |   console.log(audioData.sampleRate);
52 |   console.log(audioData.channelData[0]); // Float32Array
53 |   console.log(audioData.channelData[1]); // Float32Array
54 | });
55 | ```
