Best Free EQ Plugins
Equalization is the most fundamental mixing tool. A good EQ lets you carve space for each element, remove problem frequencies, and shape the tonal balance of your mix. These three free EQs cover everything from surgical cuts to broad tonal shaping.
1. TDR Nova (Tokyo Dawn Records)
TDR Nova is a dynamic equalizer that combines parametric EQ with frequency-selective compression. Each band can operate as a standard EQ bell or shelf, or switch to dynamic mode where it only engages when the signal crosses a threshold. This makes it incredibly versatile for taming resonances in vocals, controlling harsh frequencies in guitars, and managing low-end buildup in mixes.
Best use case: Vocal EQ, de-essing, taming resonant frequencies in any source. The dynamic bands are particularly useful for controlling sibilance without over-processing quiet passages.
2. MEqualizer (MeldaProduction)
MeldaProduction's MEqualizer is a 6-band parametric EQ with a clean, resizable interface and real-time spectrum analysis built in. It supports multiple filter shapes per band including bell, shelf, notch, band-pass, and tilt. The built-in analyzer eliminates the need for a separate spectrum display plugin on every channel.
Best use case: General-purpose EQ on any channel strip. Excellent for beginners who want visual feedback while learning how EQ affects sound.
3. TDR SlickEQ (Tokyo Dawn Records)
SlickEQ is a 3-band mixing EQ with a focus on musicality over surgical precision. It features selectable EQ models (American, British, German) that each impart subtle saturation and character. The output stage includes a subtle harmonic enhancement that adds warmth and glue.
Best use case: Broad tonal shaping on the mix bus or individual channels where you want musical color rather than transparent correction.
Best Free Compression Plugins
Compression controls the dynamic range of your audio, keeping volumes consistent and adding sustain, punch, or glue depending on settings. These free compressors range from transparent to aggressive, covering every mixing scenario.
4. TDR Kotelnikov (Tokyo Dawn Records)
TDR Kotelnikov is a wideband dynamics processor designed for transparent gain reduction. It excels at bus compression and mastering applications where you need control without audible artifacts. The interface provides clear metering of gain reduction, and the algorithm handles transients exceptionally well without pumping or distortion.
Best use case: Mix bus compression, mastering, and any situation where you need transparent dynamics control. Pairs excellently with the SlickEQ for a complete free mastering chain.
5. OTT (Xfer Records)
OTT is a multiband upward/downward compressor originally made famous as an Ableton preset. Xfer Records released it as a free standalone plugin that works in any DAW. OTT is aggressive by design: it pushes quiet details up and pulls loud peaks down across three frequency bands simultaneously. It is a staple in electronic, hip-hop, and pop production.
Best use case: Synths, bass sounds, vocal effects, and any source that needs aggressive multiband compression. Use the depth knob at 30-50% for subtle enhancement or crank it for the full OTT sound.
6. Rough Rider 3 (Audio Damage)
Rough Rider 3 is a character compressor designed for adding grit, punch, and attitude to drums, bass, and vocals. Unlike transparent compressors, Rough Rider intentionally colors the sound with its aggressive compression curve and built-in saturation. It also includes a sidechain high-pass filter and a mix knob for parallel compression.
Best use case: Drum bus smashing, parallel compression on vocals, and adding aggressive punch to bass and synths. Not for transparent compression.
Best Free Reverb Plugins
Reverb creates a sense of space and depth in your mix. A good reverb plugin is essential for placing elements in a virtual room, adding dimension to vocals, and creating atmospheric effects. These free reverbs deliver quality that rivals paid alternatives.
7. TAL-Reverb-4 (Togu Audio Line)
TAL-Reverb-4 is a high-quality plate reverb with a warm, vintage character. It features a simple interface with controls for room size, pre-delay, diffusion, and a built-in high-pass and low-pass filter for shaping the reverb tail. The algorithm produces smooth, lush tails without metallic artifacts.
Best use case: Vocals, snare drums, and instruments that benefit from a warm, plate-style reverb. Excellent for pop and R&B vocal spaces.
8. OrilRiver (Denis Tihanov)
OrilRiver is a free algorithmic stereo reverb that offers more control than most free reverbs. It features early reflections controls, multiple reverb types, 12 variations, and a 3-band EQ on the reverb output. The quality of the reverb tail is exceptionally smooth for a free plugin, and it handles both small room simulations and large hall sounds convincingly.
Best use case: Versatile room and hall reverb for any source. The early reflections control makes it particularly good for creating realistic room ambiences.
9. Valhalla Supermassive (Valhalla DSP)
Valhalla Supermassive is a reverb and delay plugin designed for massive, otherworldly spaces. It includes multiple algorithms optimized for long reverb tails, feedback delays, and lush modulated spaces. While its sweet spot is ambient and atmospheric effects, dialing back the parameters yields usable short reverbs and delays for standard mixing.
Best use case: Ambient pads, atmospheric vocal effects, long shimmer reverbs, and creative sound design. Also works as a standard reverb or delay at conservative settings.
Best Free Delay Plugins
Delay adds rhythmic repetition and depth to your tracks. From tight slapback on vocals to tempo-synced rhythmic echoes on guitars and synths, a good delay plugin is a mixing essential.
10. TAL-Dub-III (Togu Audio Line)
TAL-Dub-III is a vintage-style delay modeled after classic hardware dub delays. It features a warm, filtered feedback path that degrades naturally with each repeat, creating organic dub-style echoes. The built-in high-pass and low-pass filters shape the delay tail so repeats sit behind the dry signal without cluttering the mix.
Best use case: Vocal throws, dub effects, guitars, and any source where you want warm, musical delay repeats that fade naturally.
11. Valhalla Freq Echo (Valhalla DSP)
Valhalla Freq Echo is a frequency shifter combined with an analog-style echo. The frequency shift on the feedback path creates pitch-shifting echoes that spiral upward or downward with each repeat. This produces effects ranging from subtle chorus-like thickening to wild psychedelic spirals.
Best use case: Creative vocal effects, synth textures, transitions, and sound design. Set the frequency shift to zero for a clean analog-style delay.
12. Spaceship Delay (Musical Entropy)
Spaceship Delay is a feature-rich delay plugin with ping-pong mode, tempo sync, modulation, and built-in filtering. Despite being free, it offers the kind of flexibility you normally find in paid delay plugins. The modulation section adds movement to delay tails, and the filter section keeps repeats from building up in unwanted frequency ranges.
Best use case: All-purpose delay for mixing. Ping-pong mode works well on vocals and synths for stereo width. Tempo-synced mode keeps delays locked to the groove.
Best Free Saturation Plugins
Saturation adds harmonic richness, warmth, and perceived loudness to audio. It is the secret weapon behind mixes that sound full and engaging without being louder. These free saturation plugins range from subtle analog warmth to aggressive distortion.
13. Softube Saturation Knob
Saturation Knob is a one-knob saturation plugin from Softube that adds analog warmth and harmonic content to any source. Three modes (Keep High, Neutral, Keep Low) determine how the saturation interacts with the frequency spectrum. It is dead simple to use: turn the knob until it sounds better.
Best use case: Mix bus warmth, drum bus grit, bass enhancement. Use Keep Low mode on bass-heavy material to add harmonics without muddying the low end.
14. CamelCrusher (Camel Audio / Apple)
CamelCrusher is a legendary free plugin that combines distortion, compression, and filtering in one interface. It offers two distortion types (Tube and Mechanical) that can be blended together, a compressor, and a low-pass filter. Despite Camel Audio being acquired by Apple, CamelCrusher remains available as a free download and continues to be a go-to for adding character and aggression.
Best use case: Bass distortion, vocal grit, drum parallel processing. The Tube mode at low settings adds subtle warmth; the Mechanical mode at high settings creates aggressive distortion.
15. Krush (Tritik)
Krush is a bit crusher and downsampler that adds lo-fi character and digital distortion to audio. It features adjustable bit depth and sample rate reduction, a resonant filter, a drive stage, and a dry/wet mix knob. The modulation section allows automated parameter changes for evolving textures.
Best use case: Lo-fi effects, creative destruction on drums and synths, bit crushing on hi-hats and percussion for texture.
Best Free Utility & Analysis Plugins
Utility plugins do not process audio creatively, but they are essential for making informed mixing decisions. Spectrum analyzers, loudness meters, and correlation meters help you see what your ears might miss, especially in untreated rooms.
16. SPAN (Voxengo)
SPAN is a free real-time spectrum analyzer that displays the frequency content of your audio with precision and clarity. It supports stereo, mid/side, and multi-channel analysis with adjustable resolution, block size, and display options. The peak hold and average display modes help you identify problematic frequency buildups and tonal imbalances in your mix.
Best use case: Mix bus analysis, identifying frequency masking between tracks, verifying tonal balance against reference tracks. Put it on your master bus and every mix bus.
17. Youlean Loudness Meter (Free Version)
Youlean Loudness Meter measures integrated LUFS, short-term LUFS, momentary LUFS, true peak, and loudness range. It displays loudness over time on a graph so you can see how your track's loudness evolves. The free version covers everything you need for mixing and mastering to streaming platform standards (-14 LUFS for Spotify, -16 LUFS for Apple Music).
Best use case: Mastering to streaming platform standards, checking loudness consistency across songs in an album, and monitoring true peak to avoid clipping on lossy codecs.
18. Panagement 2 (Auburn Sounds)
Panagement 2 is a free spatial positioning tool that goes beyond simple left-right panning. It simulates 3D positioning with distance-based filtering, stereo width control, and binaural rendering. The visual interface shows where each element sits in the stereo field, making it easy to create depth and separation between sources.
Best use case: Stereo image management, placing background elements further back in the mix, creating width on mono sources, and building depth in headphone mixes.
