I did some testing on my own implementation of mp3, and used MAD as reference. Therefore I generated a sine-sweep from 0Hz to 22kHz ( as far as this is possible ;) ) at 0dBFS, and 48kHz Samplerate. Then I encoded it with Lame for a single Channel MPEG-1 Layer III Bitstream, 48kHz Samplerate, 320kbps Bitrate. (I don't know the exact Lame-version and optionstring anymore, but I didn't use anything weird)
I'm not a friend of posting large files on a mailing list without any agreement with the moderator, so if someone is interested in the bitstream and the resulting raw file, pleas feel free to send me a message.
Could the generation be done with common software? (sox? clm? nyqvist?) That could make a sort of full automatic test system if scripted.
Also, a file like that might find a home on Wikimedia or Internet Archive.
