SpecWeb is a command line (windows console) version of the SPEC stereo to surround tool from www.surroundbyus.com. It is designed to be faster and easier to use than the full “Spec” version, and does not require Plogue Bidule.
SpecWeb also has an html5 “web” user interface, which works with chrome, Firefox, iOS, android, and windows 10 edge browsers. You can control SpecWeb from a browser on the same computer or on any computer or supported device on your local network. For instance, you could sit in your home theatre listening position and control SpecWeb with an iPad.
It’s a great way to get started in making your own up mixes as all you have to do is drag and drop a lossless stereo file onto the SpecWeb icon and you get a 5.1 multichannel file in seconds.
While not all of the “knobs” from the full “Spec” version have been included, the most important ones are here and you can adjust them while you listen to the song, just as you can in the full version, then “record” the results.
qaac is a command line AAC / ALAC encoder frontend based on Apple encoder, strongly influenced by tmkk.pv.land.to/qtaacenc/.
qaac requires Apple Application Support that is included in iTunes or QuickTime. If you are using 64 bit Windows, recent 64 bit iTunes (ver 12.1 or later) is recommended. 64 bit installer for iTunes (iTunes6464Setup.exe) includes both of 32 bit and 64 bit Apple Application Support, therefore you can run both of qaac.exe and qaac64.exe with its installation.

DrumGizmo is an open source, multichannel, multilayered, cross-platform drum plugin and stand-alone application. It enables you to compose drums in midi and mix them with a multichannel approach. It is comparable to that of mixing a real drumkit that’s has been recorded with a multi mic setup.
The audio file editor, baptised ‘Eisenkraut’, came into existence (as a scaffold) during a project class on audio programming in Java at the SeaM in Weimar. It is distinguished by a number of traits which makes it particularly interesting in the field of computer music: There are no restrictions with regard to the number of channels in a file, and there is an OSC interface via which the functionality can be extended, for example using the SuperCollider language. Possible applications of such extensions are the transfer of marker information or the maintenance of meta data for segmented files, the algorithmic editing (cut/copy/paste) of files, or the addition of your own sound transformations or special decoders (e.g. an MS matrix).

The SpatGRIS is a plugin (Mac AU/VST and VST Windows format) designed to compose multichannel space. It allows the user to spatialize the sound in 2D (up to 16 speakers) or in 3D (up to 128 speakers) under a dome of speakers (with the ServerGRIS, available also on SourceForge). It includes two audio modes, — Free Volume and PanSpan — and one OSC mode. SpatGRIS is a fusion of two former plugins by the GRIS: OctoGRIS and ZirkOSC with a lot of new features. Automated Trajectories are included. It is possible to control it from external controllers such as Joystick, iPad or Leap Motion.
Features:
- Three modes: Free Volume, Pan Span, OSC Spatialization
- Automated Trajectories
- Up to 16 outputs in audio mode
- OSC Mode to control the ServerGRIS
- External controllers: Joystick, iPad. Leap Motion

Aften is an audio encoder which generates compressed audio streams based on ATSC A/52 specification. This type of audio is also known as AC-3 or Dolby® Digital and is one of the audio codecs used in DVD-Video content.
Features:
- Converts PCM source audio into AC-3 audio
- Allows for setting of production metadata such as dialogue level, downmix levels, and extended bitstream information
- Supports RAW, WAV, AIFF, and CAFF input file formats
- Supports single multi-channel or multiple mono source files
- Includes several optional pre-processing filters
- Uses multi-threading and assembly optimizations to speed up encoding
foo_dsp_xover is a software digital crossover implementation that I have been working on for a while in my spare time as a hobby. It is a Foobar2000 audio player plugin that implements this digital crossover to achieve active multi-amplification.
This software needs to run on a WinXP PC equipped with a multi-channel sound card (e.g. 5.1 or 7.1 surround sound card) feeding the various voices of a multi-amplifier and loudspeaker active configuration set-up.

HeSuVi Conversion Tool
This fairly simple tool converts all HeSuVi 14 channel presets into 7.0 formatted _L/_R stereo pairs, for use with the soon to be updated PulseAudio module-virtual-surround-sink, which I’ve updated with a faster FFT overlap-save convolver, eliminated the sample length limits for impulses, and added support for asymmetrical/dual impulse mode.
