Important Note
Initial release on KVR. Current version is not yet signed. Here are few known issues: - Phase locking modes are not yet seemless and results will vary on a number of factors. For a smooth ambient stretch, use the later phase modes. - Preset managment is missing. Defaults can restored from "burger menu" in upper right. - GUI is a bit confusing. - Builtin help is still missing. - Loads an entire file into memory and is therefore a memory hog. - For best performance, recommend using 1/8 overlap with 4096 FFT size, and Blackman windowing function. LET ME RE-EMPHASIZE: For smooth "paulstretch" behavior, go into "Settings" -> "FFT Options" -> "Mode" and then select one the "washy" options.

CONFIBLAHUTER is spectral mangling mono synth that permits freezing, stretching, shaping, and modulating of loaded audio files. This synth engine has many similar features as "paulstretch" but goes well beyond. A few highlights:

  • Can slow down audio to a freeze or speed up - independent of pitch (like many other phase vocoders) but with MIDI control and modulation possibilities.
  • Like the well-known "paulstretch" tool, it spread, hamonize, octave-ize, and distort in unique ways.
  • Use sidechain inputs and enable cross synthesis for vocoder like effects.
  • Main inputs can be used - mixed in addtion to a playing file.
  • Free-form filter to precisely mangle sonic spectra.
  • Many parameters can be modulated to make otherworldy textures.
  • Includes a record audio function (limited to 10 minutes).
  • Modulation matrix includes 4 LFOs and up to 4 MIDI controllers.
  • Can export loaded audio into other formats including a higher quality MP3.

Spectral Mangler Mono Synth
by mistakeartists.

This is a very useful and user-friendly sound-design tool. Its interface is very intuitively laid out, so just by testing its features with a few different samples, you can quickly learn how to use it.

Apart from its being able to slow down sounds extremely, I find Confiblahuter quite different in aim and approach from Paul-stretch. Neither tool sets out to do what the other specializes in.

Details: Confiblahuter comes in both stand-alone and vst3 formats.

From the first screen of four, accessible by buttons at the top left, you can load in samples. You can adjust the sample area you want to listen to by sliders, which also are available to control input / output levels, mix and pan, side-chain synthesis, pitch and in, main in / out, pitch bend, MIDI controllers. As well, there are buttons for enabling old-note, reverse, jump to loop, and note continuance. If you like what you hear, once you have made all your fine-tuning choices, you can live-record output to a file.

A second screen is dedicated to filter controls: Two sliders control mix levels of two free form filters, For either, you can draw your own filter shapes according to the real time spectral display and grid. As well, three curve types are available, with a reset button, also two sliders to adjust smoothness and curvature as minutely as desired.

The Settings screen provides sliders for FFT options (size, overlaps, window type and mode), amplitude scale, pitch bend depth and tuning. There are handy check boxes for correct phase, smooth phase and normalize.

The final screen is dedicated to the modulation possibilities of the synth: Four LFOs with dedicated wave shapes, also a whole range of different types for type 4, which has buttons for sync and reset. A very comprehensive modulation matrix is available, as well as one for assigning MIDI controllers.

In getting familiarized using this spectral mangling synth, after fifteen minutes or so, I found myself getting rather nice results - detailed ambient textures, from unexpected "noise" samples. In a way, the synth can function as a sound microscope, as well, helping bring out the hidden potential in everyday sounds. In my experience, it's a sound-design tool well-worth owning.

And for $10 USD, it's a bargain.
