Spitfire Audio has released LABS Mandolin, a free mandolin sound library for the freeware LABS sound module plugin capturing the full tonal range of a classic mandolin.
The samples were recorded at Spitfire HQ studios, including a variety of articulations. The library features picked and fingered playing styles, along with tremolo and ensemble.
It seems that the samples weren’t processed apart from standard editing, so you’re getting a clean and completely natural mandolin sound.
You can download LABS Mandolin for free from Spitfire Audio’s website. Be sure to install the LABS plugin, too. It is available in 32-bit and 64-bit VST and AU plugin formats for compatible host applications on Windows and macOS.
