Twibright Luminaplex and Hyperluma 2 are two algorithms and an example implementation developed to encode (chroma subsample) Y'CbCr video at 4:2:0 and 4:2:2 scheme with higher quality than was currently possible. Ordinary encoding introduces errors, while Luminaplex eliminates virtually all error by finding the values of minimum error. It is published as a prior art to prevent coverage by a software patent.
Twibright Pitchotron analyzes any MP3 into the semitones that are being played, displayed in a scrolling coloured graph on a video. It aids musical transcription. It includes coloured piano key stickers that enable accompanying arbitrary music and improvising even to musical analphabets.
Twibright Registrator removes noise and can quadruple the resolution of a camera in software by matching several pictures together. It can be applied to remove noise, JPEG artifacts, rain, CRT stripes, and passersby. It can enhance night photos and provide the effect of long exposure in daylight. Pictures are matched by removing shift, rotation, zoom, and brightness changes. It features high performance bilinear interpolation, automatic adaptive corrective deconvolution, 32-bit float depth, photometrically linear space, and 16-bit depth PNG output.
Twibright Syntring is a purely algorithmic string synthesizer with ASCII tab input and wav output. It doesn't use any samples, yet sounds quite realistic. Timbre, volume, and timing are adjustable in the tab file. It can be used for learning or practicing guitar or bass playing, for editing and synthesizing one's own tunes, or producing MIDI sound fonts. It is very lightweight and portable, and doesn't require any libraries.
