Package selection guidance compiled from public package information, community data, and project usage.

The ACR Cloud SDK is an unofficial Flutter package that enables sound and music recognition within Flutter applications. It leverages ACR Cloud's powerful audio fingerprinting technology to identify songs, audio content, and media in real time. Compatible with Android, iOS, and macOS, the SDK allows developers to integrate robust audio recognition features into their apps with minimal setup. The package simplifies integration by providing a clean Dart interface for calling ACR Cloud's APIs. It is ideal for music discovery, audio tagging, or interactive media experiences.

ACR Cloud SDK

** This is an unofficial SDK for flutter

Automatic content recognition (ACR) is an identification technology to recognise content played on a media device or present in a media file. This enables users quickly obtain detailed information about the content they have just experienced without any text based input or search efforts.

🤔 How ACR works

ACR can help users deal with multimedia more effective and make applications more intelligent. More info.

🚀 Initialize SDK

  final AcrCloudSdk arc = AcrCloudSdk();
  
      arc..init(
          host: '', // obtain from https://www.acrcloud.com/ 
          accessKey: '', // obtain from https://www.acrcloud.com/ 
          accessSecret: '', // obtain from https://www.acrcloud.com/ 
          setLog: false,
        )..songModelStream.listen(searchSong);
  
  void searchSong(SongModel song) async {
      print(song); // Recognized song data
  }

Initialize sdk and listen for song recognition events.

️🎶 Start Recognition

 bool started = await arc.start();

This function will automatic start the recording and recognizing process.
When there’s a result, songModelStream & resultStream will return the data as events.
The whole recognition time is controlled by ACRCloud’s Server.
You can call the stop function to terminate this process.

⛔ Stop Recognition

 bool started = await arc.stop();

This function will cancel the recognition immediately.
