Hello everybody,
I've been writing an MPEG-1 MP3 decoder from scratch for fun and giggles and it's at a point where I can throw pretty much any MP3 at it except for free format.
Now I wonder how I can verify that it actually works according to spec. I had some trouble finding MP3s that make use of mixed mode blocks but also intensity stereo.
Do you know of some ressource or maybe a test suite?
Thanks!
You can download the MP3 conformance test bitstreams from this page. (https://standards.iso.org/ittf/PubliclyAvailableStandards/) Look for 11172 and 13818.
Thank you, that's the best possible outcome :-)
