Flutter Audio Record Plugin that supports Record Pause Resume Stop and provide access to audio level metering properties average power peak power

Works for both Android and iOS

Code Samples:

Installation

add another_audio_recorder to your pubspec.yaml

iOS Permission

  1. Add usage description to plist
<key>NSMicrophoneUsageDescription</key>
<string>Can We Use Your Microphone Please</string>
  1. Then use hasPermission api to ask user for permission when needed

Android Permission

  1. Add uses-permission to ./android/app/src/main/AndroidManifest.xml in xml root level like below
    ...
    </application>
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    ...
</manifest>
  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(() {
        });
      });
