Mixxx: The Best Free and Open Source DJ Software for Windows, macOS, and Linux

If you are looking for free DJ software with no limitations that is compatible with Windows, macOS, or Linux, Mixxx definitely deserves your attention. This open-source program offers all the necessary features to mix your tracks directly from a simple computer, with or without a dedicated controller. It caters to both curious beginners and more advanced users who want a comprehensive solution without subscriptions or restrictions.

In this article, we will introduce you to Mixxx, its main features, and what it can truly offer you.

A Complete DJ Software, No Costs, No Restrictions

Mixxx is an open-source project maintained by a community of enthusiasts, without a commercial publisher behind it. The software is entirely free, with no premium version, and does not require any sign-up or impose functional limits. Once installed, you have access to all options, whether it’s mixing two tracks, chaining multiple songs in rhythm, or utilizing real-time effects.

It supports most audio formats, including FLAC, WAV, AIFF, MP3, AAC, Ogg, and Opus (lossy). You can use it with a mouse and keyboard, or connect a compatible DJ controller to achieve a more “hardware” feel of mixing. The list of supported devices is quite extensive, and presets are already available for many models such as Pioneer DDJ-SB2, Numark Mixtrack Pro 3, Hercules consoles, and more.

Mixxx offers many features for mixing music with or without external hardware. You can work with two, three, or four tracks simultaneously, with an automatic synchronization system that keeps the tracks aligned. The software automatically detects tempo and key, making transitions easier, even for beginners.

Options like Sync Lock allow you to lock the tempo between multiple tracks. This way, you can adjust the speed without losing the beat. Other tools are available, such as hot cues, rhythmic loops, audio effects, beat rolls, and even reverse playback. The quantization feature enables precise alignment of each loop with the right timing.

Mixxx also supports vinyl control using time-coded records, allowing you to manipulate your audio files as if they were pressed on vinyl. A passthrough mode can also be activated to integrate a real record into the mix.

A Well-Thought-Out Music Library

Mixxx incorporates a simple and efficient library management system. All your tracks are collected in a fast database to explore, with a search field to find a track in seconds. You can sort files by various criteria: title, artist, BPM, key, duration, and much more.

To organize your collection, you can create playlists or use the “crates” system to categorize tracks according to your own categories. The software also offers direct integration with iTunes and Traktor libraries, which can be handy if you are used to managing your music from one of these tools.

Mixxx can automatically analyze your tracks to detect tempo and key, but it can also enrich metadata using the MusicBrainz service. This function allows you to recover missing tags or correct those that are incorrectly labeled.

Mixxx allows you to easily record your sessions, whether for later listening, sharing, or archiving. You can save your mixes in FLAC, WAV, or Ogg Vorbis format. Recording in MP3 format is also possible, but you will need to install the LAME library. Once enabled, the recording function automatically saves your files in a dedicated folder accessible from the software.

The software also features a live streaming option. You can broadcast your mix online through a Shoutcast or Icecast server, with a simple setup configuration. This is practical for sharing a set with friends or streaming online on a web radio.

To ensure a consistent listening experience, Mixxx supports ReplayGain. The volume is automatically adjusted when loading a track, maintaining a constant sound level without needing to manually modify settings each time.

Chained Effects, Samplers, and Customizable Interface

Mixxx provides several options for personalizing your mixes and adapting the software to your workflow. You can chain up to three audio effects on a single track. Each effect can be adjusted independently, and parameters can be linked to a master button for simplified adjustments. You can save your effect chains, modify them at any time, and even share them if needed.

The software also includes a sampler system. Up to 64 tracks can be loaded with sounds, jingles, or short clips that can be triggered alongside the main mix. These additional tracks allow you to add sound elements without interrupting the playback of the main decks.

In terms of interface, Mixxx provides several skins with different layouts. You can choose one that best matches your hardware and habits. The display can be simplified or enriched with additional sections, depending on your preferences.
