      This package contains Pd-L2Ork, which is a fork of Pure Data that
      bundles a lot of useful extensions, brings a modern HTML5-based
      user interface, and provides a set of unique features, including
      K12 beginner mode, and L2Ork-Tweeter. While Pd-L2Ork is backwards
      compatible with Pure Data and other variants, the same is not true
      the other way around. Hence, some of the most advanced content
      created in Pd-L2Ork may not run well, or at all on other Pure Data
      variants. Pd-L2Ork is a brainchild of the Virginia Tech Linux
      Laptop Orchestra (L2Ork).
    
      
      Pure Data is an open source visual programming environment that runs on
      anything from personal computers to embedded devices (ie Raspberry Pi)
      and smartphones (via libpd, DroidParty (Android), and PdParty (iOS).
      It is a major branch of the family of patcher programming languages
      known as Max (Max/FTS, ISPW Max, Max/MSP, etc), originally developed
      by Miller Puckette at IRCAM.
    
      
      Pd enables musicians, visual artists, performers, researchers, and
      developers to create software graphically without writing lines of
      code. Pd can be used to process and generate sound, video, 2D/3D
      graphics, and interface sensors, input devices, and MIDI. Pd can
      easily work over local and remote networks to integrate wearable
      technology, motor systems, lighting rigs, and other equipment. It
      is suitable for learning basic multimedia processing and visual
      programming methods as well as for realizing complex systems for
      large-scale projects.

TeleSculptor is a cross-platform desktop application for photogrammetry. It was designed with a focus on aerial video, such as video collected from UAVs, and handles geospatial coordinates and can make use of metadata, if available, from GPS and IMU sensors. However, the software can also work with non-geospatial data and with collections of images instead of metadata. TeleSculptor uses Structure-from-Motion techniques to estimate camera parameters as well as a sparse set of 3D landmarks. It uses Multiview Stereo techniques to estimate dense depth maps on key frame and then fuses those depth maps into a consistent surface mesh which can be colored from the source imagery.

While most sound stretching software sounds bad when trying to stretch the sounds a lot, this one is optimized for extreme sound stretching. So, the stretch amount is unlimited.You can play the stretched sound in real-time (including the possibility to "freeze" the sound) or you can render the whole sound or a part of it to audio files.It has many post-processing effects, like: filters, pitch/frequency shifters.Support for WAV, OGG VORBIS files and MP3 files.It is a Free Software.

Samplebrain chops samples up into a 'brain' of interconnected small sections called blocks which are connected into a network by similarity. It processes a target sample, chopping it up into blocks in the same way, and tries to match each block with one in it's brain to play in realtime.This allows you to interpret a sound with a different one. As we worked on it (during 2015 and 2016) we gradually added more and more tweakable parameters until it became slightly out of control.
