  • All Implemented Interfaces:
    NSObject
    public class SNAudioFileAnalyzer
extends NSObject
    Analyzes an audio file and provides analysis results to the client

      • accessInstanceVariablesDirectly

        public static boolean accessInstanceVariablesDirectly()

      • addRequestWithObserverError

        public boolean addRequestWithObserverError​(SNRequest request,
                                           SNResultsObserving observer,
                                           org.moe.natj.general.ptr.Ptr<NSError> error)
        Adds a new analysis request to the analyzer If addRequest is called while the file is being processed, an error will be returned.
        Parameters:
        request - An audio analysis request to be performed on the audio stream
        observer - The object that will receive the analysis results for the supplied request. The observer is weakly retained by the analyzer.
        error - On input, a pointer to an error object. If an error occurs, this pointer is set to an actual error object containing the error information. You may specify nil for this parameter if you do not want the error information.
        Returns:
        YES if the request was successfully added, and NO otherwise.

        public static java.lang.Object allocWithZone​(org.moe.natj.general.ptr.VoidPtr zone)

      • analyze

        public void analyze()
        Analyzes the audio file synchronously This function executes synchronously. Any errors produced during analysis will flow downstream to the request observers. This method may block for a long period of time, so be careful to ensure this call does not block UI or other important tasks.

      • analyzeWithCompletionHandler

        public void analyzeWithCompletionHandler​(SNAudioFileAnalyzer.Block_analyzeWithCompletionHandler completionHandler)
        Analyzes the audio file asynchronously This function executes asynchronously, calling the completion after the entire file has completed analysis. Any errors produced during analysis will flow downstream to the request observers. If the cancelAnalysis method is called, the completionHandler will still be called, but with didReachEndOfFile set to NO.

        public static boolean automaticallyNotifiesObserversForKey​(java.lang.String key)

      • cancelAnalysis

        public void cancelAnalysis()
        Cancels any in-progress analysis of the audio file This function executes asynchronously, and will trigger the completion handler provided in the analyzeWithCompletionHandler method after the cancellation is complete.

        Creates a new analyzer
        Parameters:
        url - The url for the audio file to be analyzed
        error - On input, a pointer to an error object. If an error occurs, this pointer is set to an actual error object containing the error information. You may specify nil for this parameter if you do not want the error information.

        Parameters:
        request - An audio analysis request to be removed
