Hi Andrea
Huffman sequences are truncated impulse responses of all-pass sections.
In addition to Patterson and Green (1970), you may want to read their reference: D. A. Huffman, “The Generation of Impulse-Equivalent Pulse Trains,” IRE Trans. Inform. Technol., vol. IT-8, pp. S10-S16 (1962).

Dear List,
I know Hufmann coding but I never heard of Hufmann sequences as audio signals. Now, I'm re-reading Moore citing Patterson and Green (1970) about Hufmann sequences discrimination task.
Could anyone share some info? (if possible, I'd like to resynthesize them for didactical purposes)
Thanks a lot
Best
