How can I handle audio files?

Question

What is the best option to:

1. Record audio from microphone,
2. Store the audio as files in memory,
3. Being able to play those files ?

Is there one package that is convenient to record and play? Does it works on all platforms (web compatible)? What is the best strategy to store them in memory?

Solution

Here is a package you can use audio_recorder

• For record and storing part here is sample examples (read the package documentation)

   // Import package
   import 'package:audio_recorder/audio_recorder.dart';
  
   // Check permissions before starting
   bool hasPermissions = await AudioRecorder.hasPermissions;
  
   // Get the state of the recorder
   bool isRecording = await AudioRecorder.isRecording;
  
   // Start recording
   await AudioRecorder.start(path: _controller.text, audioOutputFormat: AudioOutputFormat.AAC);
  
   // Stop recording
   Recording recording = await AudioRecorder.stop();
   print("Path : ${recording.path},  Format : ${recording.audioOutputFormat},  Duration : ${recording.duration},  Extension : ${recording.extension},");
  

• play audio you need another package i suggest audioplayers :

  // To pause 
  int result = await audioPlayer.pause();
  
  //To Stop 
  int result = await audioPlayer.stop();
  
  // To Jump through
  int result = await audioPlayer.seek(Duration(milliseconds: 1200));
  
  // To Resume 
  int result = await audioPlayer.resume();
