## Normal usage

```dart

  CupertinoButton(

    child: Text("start capture"),

    onPressed: () async {

      bytesBuilder.clear();

      // request audio session

      final session = await AudioSession.instance;

      await session.configure(AudioSessionConfiguration(

        avAudioSessionCategory: AVAudioSessionCategory.record,

        avAudioSessionMode: AVAudioSessionMode.measurement,

        avAudioSessionRouteSharingPolicy: AVAudioSessionRouteSharingPolicy.defaultPolicy,

        avAudioSessionSetActiveOptions: AVAudioSessionSetActiveOptions.none,

      ));

      if (await session.setActive(true)) {

        subscription = betterAudioCapture?.pcmStream.listen((event) {

          bytesBuilder.add(event);

          print("recording");

        });

        betterAudioCapture?.init(sampleRate: 16000, channelCount: 1);

        betterAudioCapture?.startCapture();

      }

    });

    },

  ),

  CupertinoButton(

    child: Text("stop capture"),

    onPressed: () async {

      subscription?.cancel();

      betterAudioCapture.stopCapture();

      betterAudioCapture.dispose();

      Directory tempDir = await getTemporaryDirectory();

      File waveFile = File(tempDir.path + "/record.wav");

      if (waveFile.existsSync()) {

        waveFile.deleteSync();

      }

      IOSink waveFileSink = waveFile.openWrite();

      waveFileSink.add(BetterAudioCapture.waveHeader(bytesBuilder.length));

      waveFileSink.add(bytesBuilder.takeBytes());

      await waveFileSink.close();

    },

  ),

```
