Create a console application that will extract the metadata contained in an Apple Loop file (AIFF) and export the metadata to a JSON file. The metadata fields can be examined in the "Apple Loop Utility" for reference (must be a register apple developer to download the utility but membership is free).
The overall structure of the files are documented in the AIFF specification but the key chunks are specific to the Apple Loop format. A start at reverse engineering these chunks can be found at [url removed, login to view] The markers that contain the loop metadata are BASC, TRNS and CATE. These are the chunks that must be extracted and exported to the JSON file. There is also a Obj-C project on Github that writes an Apple Loop AIFF file and provides a good starting point ([url removed, login to view]) for the extraction process which should be similar and potentially more straightforward as only the metadata needs to be manipulated.
You can develop the application in the language of your choice and should provide both an executable and source upon completion. I will provide several loops for acceptance testing.
