The level of high and low frequencies is increased at low listening levels, to compensate for the fact that as the volume of audio decreases, the ears lower sensitivity to extreme high and low frequencies may cause these signals to fall below threshold. As a result audio material may seem to become ‘thin’ sounding at low volumes, losing bass and treble, the ‘Loudness compensation’ button (often just labelled ‘Loudness’ or ‘Loud’) is intended to rectify this situation.
flowEQ uses a disentangled variational autoencoder (β-VAE) in order to provide a new modality for modifying the timbre of recordings via a parametric equalizer. By traversing the learned latent space of the trained decoder network, the user can more quickly search through the configurations of a five band parametric equalizer. This methodology promotes using one’s ears to determine the proper EQ settings over looking at transfer functions or specific frequency controls. Two main modes of operation are provided (Traverse and Semantic), which allow users to sample from the latent space of the 12 trained models.
- Quick and easy timbral adjustments
- Automated timbral shifts over time for creative effects
- Powerful ‘tone controls’ for users in a playback/listening setting
EasyQ is an easy-to-use equalizer with an arbitrary number of filter stages in series connection. Each of the filter stages can operate in one of the following modes: peak/cut (aka bell or parametric EQ), high- or low-shelving, notch and low- or highpass (both with either 6 or 12 dB/oct slope). EasyQ is also easy on the CPU and just does what an EQ is supposed to do without performing any additional voodoo. As such, it is well suited to serve as a go-to EQ for the routine equalizing tasks.
- unlimited number of filter stages (“bands”)
- each stage can be one of the following characteristics: bell, low-/high-shelf, low-/highpass (6 or 12 dB/oct), notch
- clean equalization – no additional colorations
- low CPU usage
- +-48 dB gain range
- stereo modes: linked, left/right, mid/side and mono
- minimum phase response
The frequency response of your room is very different in every point of the room. “Good” equalization in one point can worsen the sound in the neighboring point. Single-point equalization is not reliable and cannot be used in a professional room correction system. On the other hand, multipoint equalization is not simple; both the volume and the phase of the testing signal are very different in different points of the room. Simple averaging is not applicable. MathAudio Room EQ applies a state-of-the-art multipoint correction algorithm which ensures the best possible improvement in every point of the listening area.
- Corrects deficiencies of room acoustics (multipoint compensation).
- Corrects acoustic imperfections of speakers.
- Avoids the pre-echo (pre-ringing) problem of conventional convolver-based room correction systems. The absence of pre-echo ensures the neutrality of the sound.
- Works in rooms, halls and outdoor venues of any size.
- Works with zero latency. Perfect for live performances and studio monitoring.
- Doesn’t delay the audio track when playing video.
- Corrects both amplitude and phase components of frequency response.
- Quells resonance peaks of frequency response while leaving the deep notches.
- Avoids the overcompensation which happens in conventional linearizing room correction systems.
- Manually adjustable level of compensation allows one to reach the maximum transparency of the sound.
- Supports full range of sample rates from 44,056 kHz up to 384 kHz. All sample rates are supported without resampling to avoid any possible loss in quality.
- Includes a custom target curve feature.
- Applies 64-bit signal path throughout.
- Works with USB measurement microphones (e.g. MiniDSP UMIK-1 or Dayton Audio UMM-6) or standard measurement microphones (e.g. NADY CM100 or Dayton Audio EMM-6).
Supports microphone calibration files.
- Applies a patented method of frequency response correction.

AutoEQ is a project for equalizing headphone frequency responses automatically and it achieves this by parsing frequency response measurements and producing a equalization settings which correct the headphone to a neutral sound. This project currently has almost 2000 headphones covered in the results folder. See Usage for instructions how to use the results with different equalizer softwares and Results section for details about parameters and how the results were obtained.
AutoEQ is not just a collection of automatically produced headphone equalization settings but also a tool for equalizing headphones for yourself. frequency_response.py provides methods for reading data, equalizing it to a given target response and saving the results for usage with EqualizerAPO. It’s possible to use different compensation (target) curves, apply tilt for making the headphones brighter/darker and adding a bass boost. It’s even possible to make one headphone sound (roughly) like another headphone.
Third major contribution of this project is the measurement data and compensation curves all in a numerical format except for Crinacle’s raw data. Everything is stored as CSV files so they are easy to process with any programming language or even Microsoft Excel.
Foobar DSP based graphic equalizer.
- 31 bands (1/3rd octave width)
- boost / cut range of +-12 dB in 0.1 dB steps
- master gain (can be set manually or automatically => prevents clipping for the most part)
- minimum phase (=> no pre-echo)
- approximates a smooth frequency response (=> no ‘steps’ between the bands)
- import / export presets
- mono and stereo mode

TDR VOS SlickEQ is a mixing / mastering equalizer designed for ease of use, musical flexibility and impeccable sound.
Three (and a half) filter-bands arranged in a classic Low/Mid/High semi-parametric layout offer fast and intuitive access to four distinct EQ modes, each representing a set of distinct EQ curves and behaviors. An elaborate auto gain option automatically compensates for changes of perceived loudness during EQ operation. Optionally, SlickEQ allows to exclusively process either the stereo sum or stereo difference (i.e. “stereo width”) without additional sum/difference encoding.
In order to warm up the material with additional harmonic content, SlickEQ offers a switchable EQ non-linearity and an output stage with 4 different saturation models. These options are meant to offer subtle and interesting textures, rather than obvious distortion. The effect is made to add the typical “mojo” often associated with classy audio gear.
An advanced 64bit multirate processing structure practically eliminates typical problems of digital EQ implementations such as frequency warping, quantization distortion and aliasing.
Beside the primary controls, the plug-in comes with an array of additional helpers: Advanced preset management, undo/redo, quick A/B comparison, copy & paste, an online help, editable labels, mouse-wheel support and much more.
Key specs and features:
- Intuitive, yet flexible semi parametric EQ layout
- Modern user interface with outstanding usability and ergonomics
- Carefully designed 64bit “delta” multi-rate structure
- Three EQ bands with additional 18dB/Oct high-pass filter
- Four distinct EQ models: “American”, “British”, “German” and “Soviet” with optional non-linearity
- Five output stages: “Linear”, “Silky”, “Mellow”, “Deep” and “Toasted”
- Advanced saturation algorithms by VoS (“Stateful saturation”)
- Highly effective and musically pleasing loudness compensated auto gain control
- Stereo and sum/difference processing options
- Toolbar with undo/redo, A/B, advanced preset management and more
