        public boolean appendBufferAtTimeError​(@NotNull
                                       @NotNull AVAudioPCMBuffer buffer,
                                       @Nullable
                                       @Nullable AVAudioTime time,
                                       @Nullable
                                       @Nullable org.moe.natj.general.ptr.Ptr<NSError> error)
        Add audio to the generator Audio passed to the generator should be contiguous, passing non contiguous data will affect the quality of the @c SHSignature produced. Passing the @c AVAudioTime is not required but recommended, it allows the generator to detect when the audio is not contiguous. This method only accepts PCM audio formats. The following sample rates are recommended but not required: 48000, 44100, 32000, 16000.
        Parameters:
        time - Where in the stream the audio represents
        buffer - The audio data to be appended to the signature
        error - An error if there was an issue appending the buffer

        Create a `SHSignature` from an @c AVAsset. The asset can be any type of media that has audio tracks. If the asset has multiple tracks, they will be mixed into one @c SHSignature
        Parameters:
        asset - An AVAsset that contains audio you would like to convert to a Signature
        completionHandler - A block called with the created @c SHSignature or nil and a populated error parameter if a signature could not be created. API-Since: 16.0
