TDR VOS SlickEQ ~ Equalizer Plugin

Posted by tom2tec on

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

Album Player ~ Cross-platform Audio Player

Posted by tom2tec on

Album Player is designed for composing and listening to compilations of music albums on your hard drive and CD/DVD. The Album Player plays audio files of popular formats, such as WAV, FLAC, APE, WavPack, ALAC, AIFF, TAK, MP3, MP4, OGG, MPC, Audio-CD, SACD and DVD-A. Playlists are built based on information read from .cue files.

The Album Player supports modes of direct output from a sound decoder to an output device. The elimination of intermediate processing and mixing provides the most accurate sound reproduction. The Album Player’s supported output modes are ASIO, Kernel Streaming and exclusive WASAPI.

The player displays a list of albums located on a selected drive or directory, content of a selected album, album art, artist name, and the year of release of the album. If an album’s folder contains more than one picture, they are displayed as a slide show.

No installation is required, just right-click on the player to configure it.

SoundTouch ~ Audio Processing Library

Posted by tom2tec on

SoundTouch is an open-source audio processing library for changing the Tempo, Pitch and Playback Rates of audio streams or audio files. The library additionally supports estimating stable beats-per-minute rates for audio tracks.

  • Tempo (time stretch): Changes the sound to play at faster or slower tempo than originally without affecting the sound pitch.
  • Pitch (key) : Changes the sound pitch or key while keeping the original tempo (speed).
  • Playback Rate : Changes both tempo and pitch together as if a vinyl disc was played at different RPM rate.

The SoundTouch library is intended for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects.

The SoundTouch library source kit includes also an example utility SoundStretch for processing .wav audio files from command-line interface.

Access the source codes in gitlab or download the compiled executables.

hypercyclic ~ LFO-driven, MIDI-mangling Arpeggiator

Posted by tom2tec on

What is hypercyclic?

  • an LFO-driven MIDI arpeggiator, gate effect and step sequencer
  • for mangling sustained MIDI input chords
  • the output of which can then drive other MIDI instruments
  • acts either as a VST or Audio Unit plugin for your DAW, or as a standalone application
  • the original hypercyclic won 2nd place in the KVRAudio.com Developer Challenge ‘07
  • the sweet spot for hypercyclic is the narrow border between chaos and regularity. Or, in other words, how to induce a certain pleasant randomness and syncopation, yet forcing everything to align again on the bar or beat boundaries

How do you use it?

  • the main use for hypercyclic is to generate midi that can be recorded and/or sent to other plugins. However it also features a simple built-in synth for testing purposes
  • you can use two tempo-synced LFOs to modulate various parameters for creating interesting rhythmic effects and chord variations
  • a unique feature is the possibility to modulate the sequencer step size itself, which is useful for creating glitchy stuttering effects
  • another thing you can use is a groove function for playing slightly off the beat. The groove parameters can also be modulated over time by the LFOs, adding to the rhythmic variation
