Performance improvements in Rubber Band Library

Chris Cannam

Today marks version 3.1 of the audio time-stretching and pitch-shifting library Rubber Band. This release focuses primarily on performance improvements. In version 3.0 we introduced a totally new, higher-quality processing engine, which I'll refer to as the R3 engine. The older one is still included, and I'll call that R2. Although the output of R3… Continue reading Performance improvements in Rubber Band Library

Repoint: A manager for checkouts of third-party source code dependencies

Chris Cannam

I've just tagged v1.0 of Repoint, a tool for managing library source code in a development project. Conceptually it sits somewhere between Mercurial/Git submodules and a package manager like npm. It is intended for use with languages or environments that don't have a favoured package manager, or in situations where the dependent libraries themselves aren't… Continue reading Repoint: A manager for checkouts of third-party source code dependencies

What does a convolutional neural net actually do when you run it?

Chris Cannam

There are many tutorials available that describe what they do, either mathematically or via quasi-mystical appeals to intuition, and introduce how to train and use them, often with image classification examples. This post has a narrower focus. As a programmer, I am… Continue reading What does a convolutional neural net actually do when you run it?

This is a get-together and technical conference for people who work on audio software and software-driven-hardware, in practice mostly people working on music applications. I don't go to many conferences these days, despite working in academia. I don't co-write… Continue reading Notes from the Audio Developer Conference
