Audio recorder from microphone to a given file path or stream.

No external dependencies:

• On Android, AudioRecord and MediaCodec.
• On iOS and macOS, AVFoundation.
• On Windows, MediaFoundation.
• On web, well... your browser! (and its underlying platform).

External dependencies:

• On linux, encoding is provided by fmedia. It must be installed separately.

Bluetooth is not supported on Android at this time.

* Question marks (?) in web column mean that the formats are supported by the plugin but are not available in current (and tested) browsers (Chrome / Firefox).

* AAC is streamed with raw AAC with ADTS headers, so it's directly readable through a file!

All audio output is with 16bits depth.

import 'package:record/record.dart';

final record = AudioRecorder();

// Check and request permission if needed
if (await record.hasPermission()) {
  // Start recording to file
  await record.start(const RecordConfig(), path: 'aFullPath/myFile.m4a');
  // ... or to stream
  final stream = await record.startStream(const RecordConfig(AudioEncoder.pcm16bits));
}

// Stop recording...
final path = await record.stop();
// ... or cancel it (and implicitly remove file/blob).
await record.cancel();

record.dispose(); // As always, don't forget this one.
