NOS Audio

NOS Audio plug-ins — classic digital reverb, measured from the hardware

NOS Audio makes microphones and audio software. Its Lush Halls reverb plug-ins recreate the 480L, 224XL and 300L rack reverbs that shaped the sound of records from the early 1980s onward. Rather than sampling the units with impulse responses, NOS Audio spent four years rebuilding the algorithms and calibrating them against the original hardware, program by program.

Koala Audio supplies NOS Audio software in Australia as a code and download, delivered by email — nothing to ship, and priced in Australian dollars including GST.

The NOS Audio range at a glance

Plug-in Type What it is for
Lush Halls Reverb The full version: 225 programs in 26 banks, five algorithms and up to 24 editable parameters per program. Halls, rooms, plates, chambers, ambience, delays and effects.
Little Lush Halls Reverb The same engine and the same programs as the first five banks of Lush Halls — 50 in total — with six simple controls. A quick way to get the vintage digital sound.
Lush Halls Crossgrade Reverb (crossgrade) The full Lush Halls at a reduced price, for owners of any NOS Audio software or hardware product.

Which NOS Audio reverb should I buy?

If you want the complete set and full editing — Lush Halls. Every program from all three machines, with deep parameter control and A/B comparison between machines.

If you want the sound without the parameter pages — Little Lush Halls. Pick a program, set the reverb time and mix, and move on.

If you already own a NOS Audio product — the Lush Halls Crossgrade gives you the full plug-in for less.

Buying NOS Audio plug-ins in Australia
