Matchering ~ Master Via Modeling


Matchering 2.0 is a novel Containerized Web Application and Python Library for audio matching and mastering. It follows a simple idea – you take TWO audio files and feed them into Matchering:

  • TARGET (the track you want to master, you want it to sound like the reference)
  • REFERENCE (another track, like some kind of “wet” popular song, you want your target to sound like it)

Our algorithm matches both of these tracks and provides you the mastered TARGET track with the same RMS, FR, peak amplitude and stereo width as the REFERENCE track has.

Audio File Library ~ Open Source Audio API


The Audio File Library is a C-based library for reading and writing audio files in many common formats.

The Audio File Library provides a uniform API which abstracts away details of file formats and data formats. The same calls for opening a file, accessing and manipulating audio metadata (e.g. sample rate, sample format, textual information, MIDI parameters), and reading and writing sample data will work with any supported audio file format. The Audio File Library lets you work with audio data in whatever format is most convenient for you.

OpenAIR Library ~ Open Acoustic Impulse Responses


Reverberation is an audible effect that is heard every day as a result of sound interacting with the environment around the listener. It is an effect that is commonly added artificially to electronically recorded and produced music, as well as in other media such as cinema, virtual reality applications and computer games. Auralization is an increasingly popular technique for accurately simulating reverberation and this website supports this practice through an expanding library of downloadable acoustic impulse responses (IRs) from interesting buildings, spaces and other sources.

The aim of the Open Acoustic Impulse Response (Open AIR) Library is to provide a centralized, feature rich and future proof on-line resource for anyone interested in auralization and acoustical impulse response data. For example it may be useful for researchers to quickly compare impulse responses recorded using different approaches, for developers of game audio wanting to recreate the acoustic environment of a specific building, or for musical composers looking for a desirable reverberation effect.

Demlo ~ Music Library Organiser


Demlo is a music library organizer. It can encode, fix case, change folder
hierarchy according to tags or file properties, tag from an online database,
copy covers while ignoring duplicates or those below a quality threshold, and
much more. It makes it possible to manage your libraries uniformly and
dynamically. You can write your own rules to fit your needs best.
Demlo can address any of these recurring music library issues (and much more):

  • Fix the lack of folder structure.
  • Normalize tags, fix their case, chose which tags to keep and which to discard.
  • Handle lossy and lossless audio differently.
  • Handle mp3 id3tags hell…
  • Handle multiple covers, whether embedded and/or external, resize covers,
    discard bad quality ones.

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.
