XWax
XWax is an open-source DVS (Digital Vinyl System) application for Linux, created by Mark Hills. It focuses on providing a lightweight, low-latency turntablism experience using timecoded vinyl or CDs to control digital audio files. For vinyl purists running Linux, XWax is essentially the only serious option — and it's an exceptionally good one.
The software is built with a singular focus: enabling DJs to scratch, mix, and perform with digital files using real turntables and timecoded vinyl. It supports Serato CV02/CV02.5 and Traktor Scratch MK2 timecoded records and CDs, providing accurate tracking that responds to every nuance of vinyl manipulation — scratching, backspinning, needle drops, and subtle speed variations.
XWax's latency performance is remarkable. Running on a properly configured Linux system with ALSA or JACK audio, it can achieve round-trip latencies as low as 1-2 milliseconds — far lower than what's typically achievable on Windows or macOS with commercial DJ software. This ultra-low latency is critical for scratch DJs who need instantaneous response from their turntables. The software is extremely lightweight, consuming minimal CPU and memory resources.
The interface is deliberately minimal — a functional crate browser, waveform display, and deck indicators. There are no flashy graphics, no effects, no loop tools. This minimalism is by design: XWax does one thing (vinyl control of digital audio) and does it exceptionally well. For DJs who want effects and additional features, XWax can be combined with other Linux audio tools through JACK audio routing.
XWax has found a dedicated following among turntablists, scratch DJs, and Linux enthusiasts. It's used in DJ competitions, recording studios, and live performances where reliability and responsiveness are paramount. The source code is available on GitHub, and the project welcomes contributions from developers. Despite its niche status, XWax represents an important part of the DJ software ecosystem — proving that open-source software can deliver professional-grade performance in specialized applications.
