Top Android Recorder Libraries

Top Android Recorder Libraries.

Recording audio on Android devices is a common requirement for many applications. Whether you are building a voice recorder, a music player, or a video conferencing app, having a reliable and feature-rich audio recording library can greatly simplify your development process. In this tutorial, we will explore some of the top Android audio recording libraries, their features, and how to integrate them into your Android application.

1. MediaRecorder

The MediaRecorder class is a part of the Android framework and provides a simple way to record audio. It supports various audio formats and can be easily configured to set the audio source, output format, and encoding bitrate. Here's an example of how to use MediaRecorder to record audio in Kotlin:

val outputFile = File(Environment.getExternalStorageDirectory().absolutePath, "recording.3gp")
val mediaRecorder = MediaRecorder()

mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC)
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP)
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB)
mediaRecorder.setOutputFile(outputFile.absolutePath)

mediaRecorder.prepare()
mediaRecorder.start()

// To stop recording
mediaRecorder.stop()
mediaRecorder.release()

2. EasySoundRecorder

EasySoundRecorder is a lightweight audio recording library that provides a simple API to record audio in WAV format. It offers features like recording duration limit, audio quality configuration, and automatic gain control. To use EasySoundRecorder in your Android application, add the following dependency to your build.gradle file:

implementation 'com.github.kailash09dabhi:EasySoundRecorder:1.0.0'

Here's an example of how to use EasySoundRecorder in Kotlin:

val outputFile = File(Environment.getExternalStorageDirectory().absolutePath, "recording.wav")
val soundRecorder = SoundRecorder.getInstance()

soundRecorder.setOutputFile(outputFile.absolutePath)
soundRecorder.setMaxDuration(60) // Maximum recording duration in seconds

soundRecorder.start()

// To stop recording
soundRecorder.stop()

3. AudioRecorder

AudioRecorder is a powerful audio recording library that supports recording in various audio formats like WAV, AAC, and AMR. It offers advanced features like silence detection, automatic gain control, and adjustable recording quality. To use AudioRecorder in your Android application, add the following dependency to your build.gradle file:

implementation 'com.github.adrielcafe:AndroidAudioRecorder:0.5.1'

Here's an example of how to use AudioRecorder in Java:

String outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/recording.aac";
AudioRecorder audioRecorder = AudioRecorderBuilder.with(context)
        .setFilePath(outputFile)
        .setShowConfirmation(true)
        .setDuration(15) // Maximum recording duration in seconds
        .build();

audioRecorder.start();

// To stop recording
audioRecorder.stop();

Additional Libraries:
