Normally, there are a few things to configure an audio player: The audio recording will only be stopped when user taps the “Stop” button.Įdit the “recordPauseTapped:” method with the following code: If user taps the “Pause” button, the app will pause the audio recording till the “Record” is tapped again. When user taps the “Record” button, the app will start recording and the button text will be changed to “Pause”. Before we dive into the code, let me explain how the “Record” button works. Let’s move on to implement the action method of Record button. Note: For other settings keys, you can refer to AV Foundation Audio Settings Constants. Lastly, we initiate the audio recorder by calling “prepareToRecord:” method.

In line 21-25, we use the options keys to configure the audio data format, sample rate and number of channels. The AVAudioRecorder uses a dictionary-based settings for its configuration. We will not go into the details of audio session but you can check out the official document for further details. Here, we tell iOS that the app uses “AVAudioSessionCategoryPlayAndRecord” category which enables both audio input and output. You can grab such session by calling and configure it. Upon launch, your app automatically gets an audio session.

iOS handles audio behaviour of an app by using audio sessions. In the above code, we first define the sound file URL for saving the recording. In real app, don’t forget to include proper error handling. Note: For demo purpose, we skip the error handling. Recorder = initWithURL:outputFileURL settings:recordSetting error:NULL] NSMutableDictionary *recordSetting = init] NSArray *pathComponents = [NSArray arrayWithObjects: Disable Stop/Play button when application launches The buttons are also linked up with the code. I’ve created a simple UI for you that it only contains three buttons including “Record”, “Stop” and “Play”.

To free you from setting up the user interface and code skeleton, you can download the project template from here.

AVAudioRecorder – an audio recorder for recording audioįirst of all, create a “Single View Application” and name it as “AudioDemo”.

By using the player, you can play sounds of any duration and in any audio format available in iOS.

AVAudioPlayer – think of it as an audio player for playing sound files.

In this tutorial, we mainly deal with these two classes: The AV Foundation provides easy ways to deal with audio. Our primary focus is to demonstrate the AV Foundation framework so the user interface of the app is very simple.

To provide you with a working example, I’ll build a simple audio app that allows users to record and play audio.

In this tutorial, I’ll walk you through the basics of the framework and show you how to manage audio playback, as well as, recording. One of the frameworks that you can use to play and record audio file is the AV Foundation Framework. IOS provides various framework to let you work with sound in your app. Yiqi and Raymond are independent iOS developers and have recently released Voice Memo Wifi that allows users to record voice memo and share it over WiFi. This week, we work with Yiqi Shi and Raymond from Purple Development to give you an introduction of AVFoundation framework.
