AUM Reverb is a reverse-style reverb effect, featuring a unique real-time sampling algorithm. The Algorithm is able to simultaneously sample and playback audio in real-time, while reversing and applying reverb and filter processes. The process generates solid, dynamic results, and the plug-in features many tweaks in order to make sure the results fit into your piece both rhythmically and sonically. Classic sound effects that can be produced include ghostly vocal processing, “gated” style reverb on drum hits, and unique ambient effects.
Main Features:
- Real-time Reverse Reverb Effect with a unique concurrent sampling algorithm.
- Create Dynamic (Pumping) reverb on drum sounds, unique sound effects (e.g. reversed voices, whiplash), and add massive depth and space to synth sounds.
- Includes both input and output stereo filters with modulation for moving effects, tempo-synced delay compensation, and threshold triggered-loop mode.
- MIDI-Learn assignable controls.

AudioWeather is the DAW plugin version for Le Sound’s renowned dynamic weather system AudioWeather for game audio. It demonstrates how AudioWind and AudioRain can be linked with an intelligent weather model. The goal is to allow sound designers rapidly shape the weather synchronous to the video images, saving tedious hours of manual editing of recordings.

Audion is a Windows application for creating your own audio plugins. THIS IS A WORK IN PROGRESS. We’ve divided our road map into three general phases:
Phase 1: being able to patch together preexisting modules into a working interface-less audio plugin.
Phase 2: creating a graphic interface for this plugin
Phase 3: going beyond just patching, and program new modules in a language we are calling “Fast”.We are currently in phase one; the screenshot will give you a general idea of the direction we are heading. But the road will be a long one, steep and twisting, so we are posting this preview because along the way we will welcome user input to steer us down the right path. So come, join us on this journey and we’ll see where it goes together.
For 32-bit Windows, you need to have .NET 4.0 installed to run it. As with all Transonic software, this is open source.

Audio ToolKit is a BSD-licensed library allowing to create an audio processing pipeline.
By creating filters and assembling them, you can achieve any processing you want in an efficient and reliable way.
Feel free to test the library, to enhance it by making pull requests with new features on github.

Audio Plugin Generator is a prototyping tool for audio algorithms, allowing you to create VST plugins within minutes. Plugins are generated in an automated process from Simulink models, which enables DSP engineers to develop algorithms using a clean and easily understandable representation.
The generated VST plugin gives access to parameters and signals of the underlying model. This means that parameters can be tuned in real-time and signals can be analyzed graphically. Furthermore, signals can be logged to a file, which can be used for offline analysis and easy creation of test cases.

AudaVid: Audacity(R) audio editor with synchronised video playback.
AudaVid is a customised software build of the Audacity(R) audio editor. It provides synchronised video playback using a modified version of the VidPlayVST DAW plug-in. AudaVid is used by media producers composing audio material in sync with video.
The application runs in Microsoft Windows and uses FFmpeg, which is an Open Source library of tools for working with video and audio data in multiple formats. It is able to open and play video files in any format supported by FFmpeg.
Features:
- Facility to pick out a specific cue from a longer video reel.
- Loop mode, which can be useful for live performance or rolling presentations.
- The viewport window is resizable and, optionally, the video may be viewed in a detached window or full screen.
- Video may be viewed at its original aspect ratio or scaled to fit a chosen window size.
- Plays the soundtrack if present within the video file, or it can be muted.
- Option to display SMPTE timecode.
