nightly.xam.audiorecorder

Xamarin Forms Audio Recorder Library

Features

• Ultra easy to use
• Task-based asynchronous pattern
• Register compressed audio
• Highly customizable
• Not enought??

Installation

Add nighlty.xam.audiorecorder nuget package to forms and native (iOS and Droid) apps HERE

dotnet add package nightly.xam.audiorecorder 

Usage

See Sample project in this repo. Just create a record service:

this._recordService = new NightlyRecorderService();

Start record audio:

var streamFile = await this._recordService.RecordAsync();
this._stream = streamFile;

Stop Record

this._recordService.Stop();

Isn't it easy?

The default output stream is MP4 AAR. You can easily customize SampleRate in this way:

this._recordService = new RecorderSettings.Default.WithSampleRate(SampleRate.Low);

or you can use others ready to use configurations in this way:

 this._recordService = new NightlyRecorderService(new RecorderSettings
  {
     IosRecorderSettings = new IosAppleLossLess(),
     DroidRecorderSettings = new DroidOggOpus()
 });

Permission

This library doesn't manage permission for record audio from device MIC. I Suggest you to use Xamarin Essentials Permission API like this:

var status = await Permissions.CheckStatusAsync<Permissions.Microphone>();

    if (status != PermissionStatus.Granted)
    {
        status = await Permissions.RequestAsync<Permissions.Microphone>();
        if (status != PermissionStatus.Granted)
        {
            await this.DisplayAlert("Alert","you need pemrission to mic", "ok");
            return;
        }
    }

API

You can customize iOS and Android record settings implementing the following interfaces

  public interface IIosRecorderSettings
    {
        IosAudioFormat AudioFormat { get; set; }
        double? SampleRate { get; set; }
        int? NumberChannels { get; set; }
        int? LinearPcmBitDepth { get; set; }
        bool? LinearPcmBigEndian { get; set; }
        bool? LinearPcmFloat { get; set; }
        bool? LinearPcmNonInterleaved { get; set; }
        IosAudioQuality? AudioQuality { get; set; }
        IosAudioQuality? SampleRateConverterAudioQuality { get; set; }
        int? EncoderBitRate { get; set; }
        int? EncoderBitRatePerChannel { get; set;}
        int? EncoderBitDepthHint { get; set; }
    }

    public interface IDroidRecorderSettings
    {
        DroidAudioEncoder AudioEncoder { get; }
        DroidOutPutFormat OutPutFormat { get; }
        int? SamplingRate { get; set; }
        int? AudioChannels { get; set; }
        int? CaptureRate { get; set; }
        int? AudioEncodingBitRate { get; set; }
    }

After implementing those interfaces you can create a record service:

this._recordService = new NightlyRecorderService(new RecorderSettings
  {
     IosRecorderSettings = new YourIosImplementation(),
     DroidRecorderSettings = new YourDroidImplementation()
 });

OOB Record Configuration

There are some ready to use implementation:

iOS

• IosAppleLossLess
• IosFlac
• IosMp4Aar

Droid

• Droid3GppAar
• DroidOggOpus
• DroidMp4Aar
