Foobar2000 & MathAudio Room EQ


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.

FreeG ~ Fader Plug-in


The Sonalksis FreeG is everything you need in a master fader. A simple, but absolutely indispensable plug-in, the FreeG extends the functionality of a typical audio host by providing a large-format style fader, along with ultra accurate metering. FreeG helps to maximise workflow with extended, customizable metering, and multiple control features and settings.

When working with digital audio, a lack of fine metering and extended signal flow control in the host is a common issue. FreeG helps to improve workflow in the host by providing these features in the insert chain. By delivering enhanced control of amplitude, phase and pan (stereo version) in the insert chain as well as fine metering, with user configurable industry standard ballistic options, the freeG is the perfect master control.

Features:

  • Long-throw fader
  • Ultra accurate metering
  • Multiple metering ballistic types
  • Peak and RMS readouts
  • Pre/Post metering options
  • Selectable Pan-Law
  • ‘Fine’ mode for sensitive calibration of the master fader
  • Mono-compatible for use in tracking situations
  • VST and Audio Unit (32 and 64 bit)

Similarity ~ Refines Music Collections


As an active music fan you surely know how difficult it sometimes may be to keep your music collection ordered. The more sound files you have, the more time and effort it takes to clean out duplicates, low-quality files and purify the entire collection of any musical garbage it contains. That’s where Similarity comes in handy!

Similarity rapidly scans your music collection and shows all duplicate music files you may have. The comparison, powered by “acoustic fingerprint” technology, considers the actual contents of files, not just tags or filenames, and thus ensures the extreme accuracy of similarity estimation. Moreover, the comparison isn’t audio file format dependent; the application supports almost every file format in full.

Alongside eliminating musical doubles, Similarity also provides advanced quality control functions. Really, who wants a collection full of low-bitrate music, badly remastered compositions and songs full of noise? Similarity analyzes files and calculates a quality score basing on various technical parameters of that recording, such as: bitrate, frequency, amplitude cut value, amplitude average value, amplitude maximum and many others. The program automatically detects all common problems with audio files and assigns a corresponding quality mark to each file. A quick sort – and you’ve got files with the highest quality at the top and files you can delete without doubts at the bottom.

Wider ~ Powerful Stereo Expansion


Pseudo stereo without phase issues. Wider takes the massively popular stereo section from its sibling, Manipulator, and creates the illusion of an expanded stereo image of a mono signal to an awe-inspiring amount of width. However, Wider is a unique stereo plugin in the sense that it is completely “mono-compatible”, meaning that any signal that has been extended will always remain in phase with itself, even if summed to mono.

AnSpec ~ Analog-style Spectrum Analyzer


AnSpec is an analog-style one/third-octave spectrum analyzer AAX, AudioUnit and VST plugin for professional sound and music production applications. It was designed to be a handy visual feedback tool for those who like visual smoothness and easiness of use of analog analyzers. AnSpec also provides peak level indication.

While there are no adjustable parameters available in this plugin, you can still change level meter ballistics and resize plugin’s window.

Features:

  • 1/3 octave analog-style spectrum analyzer
  • Peak level indication
  • User interface window resizing
  • Stereo and mono analysis
  • All sample rates support
  • Zero processing latency
  • User interface color schemes
  • Resizable user interface
  • Retina and High DPI support

Spleeter ~ Source Separation Library


Spleeter is the Deezer source separation library with pretrained models written in Python and uses Tensorflow. It makes it easy to train source separation model (assuming you have a dataset of isolated sources), and provides already trained state of the art model for performing various flavour of separation:

  • Vocals (singing voice) / accompaniment separation (2 stems)
  • Vocals / drums / bass / other separation (4 stems)
  • Vocals / drums / bass / piano / other separation (5 stems)

2 stems and 4 stems models have state of the art performances on the musdb dataset. Spleeter is also very fast as it can perform separation of audio files to 4 stems 100x faster than real-time when run on a GPU.

We designed Spleeter so you can use it straight from command line as well as directly in your own development pipeline as a Python library. It can be installed with Conda, with pip or be used with Docker.

AutoEQ ~ Automatic Headphone Equalization


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.
