Support for wave form

[subhendukundu]

Is your feature request related to a problem? Please describe.

It's difficult to make real-time waves from an audio recorder such as Instagram.

Describe the solution you'd like

A method to get the wave data which we can pass plugin such as flutter_visualizers.

Describe alternatives you've considered

I haven't found a workaround either.

Did you try to startRecorder() to a dart stream ?

[subhendukundu]

Yes! I have it like

await recorder.startRecorder(
      codec: Codec.aacMP4,
      toFile: outputFile.path,
      sampleRate: 16000,
 );

I am trying to get the waves so that I can pass it on to generate the waves in ui. For example

new LineVisualizer(
              waveData: wave,
              height: MediaQuery.of(context).size.height,
              width : MediaQuery.of(context).size.width,
              color: Colors.blueAccent,
 ),

You record to a file. If I understand well, you want to get a Stream for sending the data to another plugin. Instead of toFile: you should use toStream: parameter.
