Analyzers and meters are audio tools used to measure and display various aspects of a sound signal. Analyzers provide a visual representation of frequency content, allowing you to see the distribution of different frequencies in your audio. Meters, on the other hand, measure levels such as volume, loudness, phase, or stereo balance.
The Youlean Loudness Meter is a great tool if you need to measure the true loudness of your audio and make sure it’s ready for TV or streaming. Tons of producers already use it, and it works in pretty much any DAW—whether you’re using FL Studio, Logic, Ableton, or even something like Final Cut or Pro Tools. It helps you hit the right loudness.
Voxengo SPAN is a free real-time FFT audio spectrum analyzer plugin for AAX, AudioUnit, and VST formats. It offers customizable spectrum analysis with adjustable Fourier block size, overlap, visual slope, and multi-channel support. SPAN also includes stereo correlation, RMS, true peak level, amongst many other specs. 100% Worth having.
MAnalyzer is an advanced spectral analyser and sonogram featuring smoothing, normalisation, super-resolution, prefiltering, and deharmonisation. It also includes a peak meter and loudness meters compliant with EBU R128 and ITU-R BS 1770-3 standards, making it a powerful tool for precise audio analysis. I prefer this one to Voxengo SPAN. 👀👀
MIDI Monitor is a free app for Mac that displays incoming and outgoing MIDI signals. Im a windows guys, so was only able to test this on virtual machine. It’s really useful for musicians troubleshooting MIDI issues and programmers testing MIDI drivers and apps. It is open-source, available under the BSD license, and supports macOS 10.13 (High Sierra) and later versions.
Equalizers (EQs) and filters are audio tools used to shape a sound’s frequency content. EQs adjust specific frequency ranges, boosting or cutting areas like bass, mids, or treble to balance or enhance a mix. Filters are specialized EQs that remove unwanted frequencies, such as low-pass (cutting highs) or high-pass (cutting lows), to clean up the sound. Together, they help refine audio quality and control tonal characteristics in music production and mixing.
TDR Nova is a parallel dynamic equalizer with a familiar parametric EQ layout, featuring dynamic controls on each band for versatile processing. Whether you’re adding density to a mix, enhancing a drum bus, or addressing sibilance, Nova offers a smooth solution. With a drag-and-drop interface and classic knob controls, it provides quick access to its powerful features, including four dynamic EQ bands.
ReaFIR is a versatile FFT-based dynamics processor offering FFT sizes from 128 to 32,768. It features a useful frequency response display with flexible response curve control, either by points or freehand. It serves as a linear phase mastering EQ, a precise surgical EQ, a multi-band compressor, and a noise subtractor by building noise profiles. Additionally, it can gate audio with per-band threshold control.
Filterstep’s motion-based filter engine delivers tempo-synced rhythmic movement for Mac and Windows users, fully compatible with VST, VST3, AU, AAX, and standalone formats. Its standout feature is real-time groove generation with evolving pattern control, including Infinity Mode for non-repeating motion. You can shape filter sequences with quantization, customizable ranges, and MIDI control.
PREDD plugin emulates the iconic REDD.47 console, featuring a Mic/DI switch, Voltage Gain knob, -20dB pad, 10dB High Boost, Phase Invert, and a Rumble Filter (20-180Hz). With Fine Gain Set for precise adjustments and easy output control, it promises to deliver the warmth and character of classic analog sound. Although it’s not yet tested, Analog Obsession’s reputation for high-quality emulations sets high expectations for this plugin!
Pitch and tuning VSTs help musicians and producers adjust the pitch and fine-tune audio in their recordings. These plugins can correct off-key notes, adjust pitch shifting, or apply creative effects like harmonization. Common features include auto-tuning, manual pitch correction, and formant shifting. Popular VSTs in this category allow for both subtle tuning adjustments and more dramatic effects, catering to various genres and production styles.
GVST GSnap is a free pitch-correction VST plugin that can subtly correct off-key vocals or create the iconic “robot voice” effect, like T-Pain or Cher. It supports MIDI control, allowing you to reshape a recording to a new melody. Best used on monophonic inputs like vocals, GSnap offers versatile autotuning for music production.
MAutoPitch is a free, easy-to-use automatic vocal tuning and pitch correction plugin designed for vocals and other monophonic instruments. It not only improves pitch but also offers creative features like formant shifting and stereo expansion, making it a versatile tool for quick and effective audio adjustments.
MTuner is a free analyzer designed for tuning guitars, basses, and other instruments. It features both a classic monophonic tuner for single notes and a high-resolution polyphonic tuner, allowing users to quickly tune multiple strings simultaneously. With its user-friendly interface and accurate tuning capabilities.
Workflow and technical control VST plugins are precision tools built to optimise your production process. Unlike creative effects, these plugins focus on accuracy, signal management, stereo control, blind testing and technical correction.
From mastering-safe stereo width adjustments and objective plugin comparison to signal recording and advanced gain staging, these tools help you make better decisions, eliminate bias and maintain full technical control over your sessions.
MRecorder is a straightforward utility plugin from MeldaProduction that records the incoming signal directly to a WAV file inside your DAW. Ideal for printing stems, capturing processed audio or archiving test passes, it supports mono, stereo, M/S, surround.

MUtility offers essential functions and effects for audio engineers, such as volume control, panorama, phase inversion, stereo swapping, and a DC blocker. It also includes advanced features like delay, RMS and envelope, mathematical functions, an expression evaluator.
Gain and dynamics processing are essential tools in audio production used to control the level and intensity of sound. Gain adjusts the signal’s volume, ensuring proper input levels. Dynamics processing, which includes tools like compression, limiting, expansion, and gating, manages the dynamic range of audio by controlling the volume fluctuations. This helps keep sound consistent, prevents distortion, and adds punch or smoothness to a mix. These techniques are vital for achieving a balanced, polished sound across different audio elements in a track.
Gainer is a free gain-staging plugin designed to give you precise control over gain levels at every stage of your signal chain. While DAWs provide basic gain control for tracks and master buses, Gainer steps in where more flexibility is needed, especially for plugins that lack input gain controls. It allows you to monitor and adjust gain levels between plugins, offering up to +24dB or -100dB.
The Gain plugin offers straightforward and precise volume control, allowing you to easily adjust the loudness of your audio by increasing or decreasing the gain in decibels.

The built-in VU Meter provides real-time visual feedback, displaying the levels of both left and right.
The Bluecat gain suite plugin offers advanced MIDI control and automation, allowing full customization of response curves for dynamic audio manipulation. When paired with an analysis tool or MIDI controller, you can remotely adjust the gain of each audio channel, no matter where it sits in the signal chain. Blue cat plugins are so well made. I think I own most of them if not all. Well made tools, Free!
