Professional multitrack machines tended to extrapolate from the professional two‑track formats: half‑inch tape generally supported four tracks, one‑inch carried eight, and two‑inch had 16 or 24 tracks. Sixteen tracks on two‑inch tape provides broadly the same quality as half‑track quarter‑inch and is a highly regarded format — but 24 tracks offered versatility, and in the '70s, 24‑track became the de facto standard. Again, noise‑reduction systems were commonly used (Dolby A and latterly Dolby SR being the favoured choices), and were absolutely necessary with the two‑inch, 24‑track format.
