I work on enhancement of audio modules testing [1], and I need free (in 
both senses) small sample audio files in different formats. We already 
have audiotest.au (mono, and sunau has a bug in processing multichannel 
files [2]) and Sine-1000Hz-300ms.aif, but this is not enough. I have 
generated a pack of files like Sine-1000Hz-300ms.aif by Python, it is 
enough for regression testing but only if current implementation is correct.

I found some collections of sample files at [3], but I'm not sure about 
copyright, and perhaps they are a little too big.

In ideal it should be one high-quality (float64?) multichannel (5+1?) 
but short master file and it's lower-quality copies made by third-party 
tools. In ideal the content should be related to Python.
