Spitfire Audio is an English technology company based in London that creates virtual instrument sample libraries used for music production.

Composers and musicians play the virtual instrument within a digital audio workstation via MIDI to create new music.

In addition to direct recordings of individual and groups of instruments, Spitfire has collaborated with noted film composer Hans Zimmer, Red Hot Chili Peppers drummer Chad Smith, Ólafur Arnalds, Roger Taylor of Queen, Eric Whitacre, guitarist Leo Abrahams, and posthumously with the explorer and musician David Fanshawe, in creating mixed audio productions for television and film use.

[4] Run by a small group of volunteers, the channel is dedicated to creating and sharing sampled instruments for free.
