getUnusedAudioRecordingFilePath()

Error AudioFileManager::getUnusedAudioRecordingFilePath	(	String &	filePath,
		String *	tempFilePathForRecording,
		AudioRecordingFolder	folder,
		uint32_t *	getNumber,
		const char *	channelName,
		String *	songName )

If songname isn't supplied the file is placed in the main recording folder and named as samples/folder/REC###. If song and channel are supplied then it's placed in samples/folder/song/channel_###
