VoiceRecorderWavebarComponent
The VoiceRecorderWavebarComponent displays the amplitudes of the recording while the recording is in progress
The component doesn't have any inputs, instead it uses the AudioRecorderService and the AmplitudeRecorderService to gather all necessary data.
Usage
<stream-voice-recorder-wavebar
*ngIf="isRecording$ | async"
></stream-voice-recorder-wavebar>isRecording$: Observable<boolean>;
constructor(public readonly recorder: AudioRecorderService) {
this.isRecording$ = this.recorder.recordingState$.pipe(map(s => s === MediaRecordingState.RECORDING || s === MediaRecordingState.PAUSED));
}
