F9 Audio is a London-based music production resource founded by James Wiltshire, a producer best known as half of the Grammy-nominated house duo Freemasons. The company focuses on royalty-free sample packs, multi-sampled instruments, synthesizer presets, drum kits, and DAW templates aimed at electronic music producers working in Ableton Live, Logic Pro, and other modern DAWs.

Its catalog spans genre-focused template series such as F9 TRAX (with volumes covering house, funk, and city-themed productions like Los Angeles and Milano), multi-sampled instrument libraries like F9 Nautilus and F9 Mercury P5, the F9 Galaxy Toolkit for Ableton Live, and the F9 Drumtrax stem series. Many of the company's releases capture hardware synths, drum machines, and studio gear through detailed multisampling, packaged with preset banks for popular soft synths.

Alongside its commercial products, F9 Audio publishes a long-running series of free production tutorials on YouTube covering mixing, sound design, and arrangement techniques, which has helped build its reputation within the house and electronic production community.

F9 Audio has 14 products cataloged on Equipboard, including Drums, Soft Synth Presets, and Classic House.
