Are there any standard test tracks for audio codecs? I mean something as classic as Lena for testing image processing?

I'm interested in testing 'new' codec implementations (actually testing various lossless algorithms and how they behave with different types of audio data - just for educational use. I managed to make a collection of my own samples, but my thesis supervisor asked me to look for some 'standard samples', if they exist).

For lossless, I'd consider a hearing test pointless, since you'd be comparing copies of the source file over and over
again -> lossless. File comparison should do the job for that, i.e. to tell if it is really lossless.
Otherwise you'd be judging the quality of the source recording, let it be SQAM or anything else.
