Agenda

ToneShaper

Create sounds graphically

Audio samples are generated with numerical integration of user defined instantaneous frequency curves.

Epicycles

Experiment with complex Fourier series

Fourier coefficients of a 2D curve are generated with numerical integration and displayed as epicycles.

TonePlayer

Play and save frequency tones

Implements a continuous frequency slider and other controls to configure and play tones.

TimeWarp Editor

Extension of TimeWarp

Discover how TimeWarp can be adapted to variably time scale one or more portions of a video.

PlotAudio

Draws audio waveforms

Learn how to create a visual representation of audio by plotting its samples as decibels.

TimeWarp

Create an app to variably time scale video

Variably speed up or slow down the rate of play of video across its timeline.

Scaling Video Files

Create an app to time scale your video files

Our time scaling technique for audio is adapted to uniformly speed up or slow down the rate of play of video.

Scaling Audio Files

Learn how to scale all audio channels in the time domain

Discussion on how to use the Accelerate framework to speed up or slow down the rate of play of an audio file.

Reversing Audio Files

Learn how to read and write audio to reverse it

Discussion on how to reverse one channel of an audio file by reading and writing samples with AVFoundation.

Gravity - Augmented Reality

Create videos with AR objects

We’ve just released version 1.0 of Gravity, an app that lets you add virtual AR objects to videos.

Working with Live Photos

In-depth discussion about the Apple Live Photo format

Learn how to extract the Live Photo resources and create Live Photos programmatically from any photo and video.

Website Redesign

Our website is now hosted on Github Pages using Jekyll! We decided to transition from Squarespace to hosting on Github for several reasons.
