 # Audio Waveforms Use this plugin to generate waveforms while recording audio in any file formats supported by given encoders or from audio files. We can use gestures to scroll through the waveforms or seek to any position while playing audio and also style waveforms. ## Preview **Check [migration guide](https://github.com/SimformSolutionsPvtLtd/audio_waveforms/blob/main/migration_guide.md) to migrate from 0.1.5+1 to 1.0.0** ## Recorder ### Platform specific configuration **Android** Change the minimum Android sdk version to 21 (or higher) in your `android/app/build.gradle` file. ``` minSdkVersion 21 ``` Add RECORD_AUDIO permission in `AndroidManifest.xml` ``` ``` **IOS** Add this two rows in `ios/Runner/Info.plist` ``` NSMicrophoneUsageDescription This app requires Mic permission. ``` This plugin requires ios 10.0 or higher. So add this line in `Podfile` ``` platform :ios, '10.0' ``` **Installing** 1. Add dependency to `pubspec.yaml` ```dart dependencies: audio_waveforms: ``` *Get the latest version in the 'Installing' tab on [pub.dev](https://pub.dev/packages/audio_waveforms)* 2. Import the package. ```dart import 'package:audio_waveforms/audio_waveforms.dart'; ``` ### Usage 1. Recording audio ```dart RecorderController controller = RecorderController(); // Initialise await controller.record(path: 'path'); // Record (path is optional) final hasPermission = await controller.checkPermission(); // Check mic permission (also called during record) await controller.pause(); // Pause recording final path = await controller.stop(); // Stop recording and get the path controller.refresh(); // Refresh waveform to original position controller.dispose(); // Dispose controller ``` 2. Use `AudioWaveforms` widget in widget tree ```dart AudioWaveforms( size: Size(MediaQuery.of(context).size.width, 200.0), recorderController: controller, enableGesture: true, waveStyle: WaveStyle( ... color: Colors.white, showDurationLabel: true, spacing: 8.0, showBottom: false, extendWaveform: true, showMiddleLine: false, gradient: ui.Gradient.linear( const Offset(70, 50), Offset(MediaQuery.of(context).size.width / 2, 0), [Colors.red, Colors.green], ), ... ), ), ``` **Advance usage** ```dart controller.updateFrequency = const Duration(milliseconds: 100); // Update speed of new wave controller.androidEncoder = AndroidEncoder.aac; // Changing android encoder controller.androidOutputFormat = AndroidOutputFormat.mpeg4; // Changing android output format controller.iosEncoder = IosEncoder.kAudioFormatMPEG4AAC; // Changing ios encoder controller.sampleRate = 44100; // Updating sample rate controller.bitRate = 48000; // Updating bitrate controller.onRecorderStateChanged.listen((state){}); // Listening to recorder state changes controller.onCurrentDuration.listen((duration){}); // Listening to current duration updates controller.onRecordingEnded.listen((duration)); // Listening to audio file duration controller.recordedDuration; // Get recorded audio duration controller.currentScrolledDuration; // Current duration position notifier ``` ## Player ### Usage ```dart PlayerController controller = PlayerController(); // Initialise // Extract waveform data final waveformData = await controller.extractWaveformData( path: 'path', noOfSamples: 100, ); // Or directly extract from preparePlayer and initialise audio player await controller.preparePlayer( path: 'path', shouldExtractWaveform: true, noOfSamples: 100, volume: 1.0, ); await controller.startPlayer(finishMode: FinishMode.stop); // Start audio player await controller.pausePlayer(); // Pause audio player await controller.stopPlayer(); // Stop audio player await controller.setVolume(1.0); // Set volume level await controller.seekTo(5000); // Seek audio final duration = await controller.getDuration(DurationType.max); // Get duration of audio player controller.updateFrequency = UpdateFrequency.low; // Update reporting rate of current duration. controller.onPlayerStateChanged.listen((state) {}); // Listening to player state changes controller.onCurrentDurationChanged.listen((duration) {}); // Listening to current duration changes controller.onCurrentExtractedWaveformData.listen((data) {}); // Listening to latest extraction data controller.onExtractionProgress.listen((progress) {}); // Listening to extraction progress controller.onCompletion.listen((_){}); // Listening to audio completion controller.stopAllPlayer(); // Stop all registered audio players controller.dispose(); // Dispose controller ``` **Use `AudioFileWaveforms` widget in widget tree** ```dart AudioFileWaveforms( size: Size(MediaQuery.of(context).size.width, 100.0), playerController: controller, enableSeekGesture: true, waveformType: WaveformType.long, waveformData: [], playerWaveStyle: const PlayerWaveStyle( fixedWaveColor: Colors.white54, liveWaveColor: Colors.blueAccent, spacing: 6, ... ), ... ); ``` ## Main Contributors
