  1. Then use hasPermission api to ask user for permission when needed

Configuration #

iOS Deployment Target is 8.0 above

Android

  • AndroidX: use latest version (0.5.x)
  • Legacy Android: use old version (0.4.9)

Usage #

Recommended API Usage: hasPermission => init > start -> (pause <-> resume) * n -> stop, call init again before start another recording

Always check permission first(it will request permission if permission has not been set to true/false yet, otherwise it will return the result of recording permission)

bool hasPermission = await AnotherAudioRecorder.hasPermissions;

Initialize (run this before start, so we could check if file with given name already exists)

var recorder = AnotherAudioRecorder("file_path.mp4"); // .wav .aac .m4a
await recorder.initialized;

or

var recorder = AnotherAudioRecorder("file_path", audioFormat: AudioFormat.AAC); // or AudioFormat.WAV
await recorder.initialized;
Sample Rate
var recorder = AnotherAudioRecorder("file_path", audioFormat: AudioFormat.AAC, sampleRate: 22000); // sampleRate is 16000 by default
await recorder.initialized;
Audio Extension and Format Mapping
Audio Format Audio Extension List
AAC .m4a .aac .mp4
WAV .wav

Start recording

await recorder.start();
var recording = await recorder.current(channel: 0);

Get recording details

var current = await recording.current(channel: 0);
// print(current.status);

You could use a timer to access details every 50ms(simply cancel the timer when recording is done)

new Timer.periodic(tick, (Timer t) async {
        var current = await recording.current(channel: 0);
        // print(current.status);
        setState(() {
        });
      });
