The 10 best free mixing plugins you need for your music

From EQs and compressors to reverbs and saturators, a wide array of plugins are often used when mixing a track.

While the stock plugins available right within your DAW should never be underestimated, sometimes you might be looking for a more specialized function, or perhaps you simply want to try something new—ideally without breaking the bank. In the video above, Max Rewak shares ten free mixing plugins that you can try out today to expand your creative horizons. Join us to hear each of them in the context of a production, and learn more and download them via the links below.

10 great free mixing plugins:

1. OTT by Xfer Records

One of the most iconic free mixing plugins out there, Xfer Records’ OTT is a powerful multi-band compressor. In fact, it might even feel too powerful in many use cases upon first loading it up—but try dialing down the Depth parameter, and you’ll quickly find it can allow you to shape your sounds in more subtle ways and help them stand out in your mix.

Go to 0:28 in the video to learn more about OTT and hear it in action.

2. Saturation Knob by Softube

Softube’s Saturation Knob is a plugin that truly embodies the concept of “less is more.” The one-knob saturator is unassuming at a glance, but can be a great tool for quickly and effectively adding some harmonic energy to your drums, basses, vocals, and more.

3. Valhalla Supermassive by Valhalla DSP

Are you looking to achieve those delays and reverbs that sound both massive and clean at the same time? Look no further than Valhalla Supermassive. Featuring an intuitive UI and 16 constellation-inspired modes, the plugin shines at making your tracks sound truly larger than life.

4. Finisher Micro by UJAM

Few mixing plugins do what UJAM’s Finisher Micro does. The plugin is a one-knob multi-effects plugin that you can use to find instant inspiration and endless sonic variety. While it might not be great for getting really precise with individual parameters, if you’re looking to explore creative possibilities that you might not come across naturally, Finisher Micro is sure to be a great addition to your toolkit.

5. SonEQ by Sonimus

We can’t talk about free mixing plugins without touching on at least one EQ. Sonimus’ SonEQ is a solid plugin in this department that features a classic UI and all the parameters you’ll need to sculpt your sound. Its Drive knob is also a great bonus, allowing you to dial in some saturation on top of your EQ without disrupting your workflow.

6. Klanghelm DC1A by Klanghelm

Also featured in our recent post on the best free plugins for your vocal chain, the Klanghelm DC1A compressor is a nifty tool that can address a wide array of mixing needs with just two knobs. The secret is combining them with its four modes (Deep, Relaxed, Dual Mono, and Negative), which allow you to do everything from channel-independent processing to parallel compression.

7. DLYM by Imaginando

Short for “Delay Modulator,” DLYM is a free plugin from Imaginando that produces chorus and flanger-style effects. Despite sounding somewhat specialized, exploring its built-in preset library will give you a sense of just how versatile the plugin can be. Automating parameters like Time and Feedback can also allow you to create neat effects and transitions, as demonstrated in our tutorial.

Go to 10:58 in the video to learn more about DLYM and hear it in action.

8. BitterSweet by Flux

Flux’s BitterSweet is a transient shaper that allows you to easily emphasize or attenuate the transients in your tracks. While its characterization of less transients as “Sweet” and more transients as “Bitter” may not always apply in practice, the semantics don’t distract from the fact that BitterSweet does exactly what it needs to do, extremely well.

Go to 12:50 in the video to learn more about BitterSweet and hear it in action.

9. Kilohearts Essentials by Kilohearts

If you’re looking for a wider selection of plugins to play around with, Kilohearts Essentials is a great bundle to check out. The ever-growing collection includes the basics as well as more niche units (see their Ladder Filter or Trance Gate), and you could very easily start and finish your mix using nothing but its plugins.

10. Youlean Loudness Meter (free version) by Youlean

Last but not least, we have an honorable mention in Youlean Loudness Meter. While the pro version is technically paid, the free version also allows you to access high-quality metering features that are great for mixing as well as mastering. From true peak and loudness graphs to a loudness distribution chart and the ability to set custom alert thresholds, Youlean Loudness Meter offers everything you’ll need and then some.
