SpecWeb ~ Converts 2 Channels To Multichannel 5.1


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 ~ AAC / ALAC Encoder


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.

Features:
  • AAC-LC, AAC-HE, ALAC encoding are supported. m4a container (just a MP4 container with ‘M4A ‘ brand, created by Apple) is used by default, but you can also mux into ADTS.
  • Filenames and tags are treated with Unicode. Very long file names are supported.
  • Support for multichannel / surround.
  • Fine quality control over AAC encoding.
  • Support for hi-resolution / multichannel ALAC.
  • WAV, raw PCM, ALAC, and all LPCM formats supported by CoreAudio AudioFile interface (such as AIFF, CAF, and Sun/AU) are directly available as input. MP3 is also decodable through CoreAudio.
  • Cue sheet input is also available.
  • FLAC, Wavpack, TAK, and other LPCM formats are optionally supported when libFLAC.dll, wavpackdll.dll, tak_deco_lib.dll, and libsndfile-1.dll are installed.
  • Piped input is available for WAV and raw PCM.
  • Piped output (streaming) is supported for ADTS.
  • Automatically fetch tags from AIFF, FLAC, Wavpack, Tak, and ALAC. Major tags are copied to the result. Also, you can manually set tags via command line options.

DrumGizmo ~ Multilayered Drum Application & Plugin


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 has been recorded with a multi mic setup.

Features:
  • Stand-alone, Lv2 and VSTi versions available
  • Open drumkit file format, allowing the community to create their own drumkits
  • Drum velocity, allowing for several different hit velocities for each drum
  • Multichannel output, making it possible to mix it just the way you would a real drumkit
  • Optional built-in humanizer, analyzing the midi notes, adjusting velocities on-the-fly
  • Stand-alone midi renderer, generating .wav files, 1 for each channel
  • Stand-alone midi input, making it possible to use DrumGizmo as a software sampler for an electronic drumkit

Eisenkraut ~ Multi-channel Audio Editor


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).
