RTcmix for Linux: Part 1

In the first part of this three-part series on real-time audio synthesis, we take you through the history and basis of RTcmix.

RTcmix is an incredibly powerful and flexible package because of the work of many people, and possible because of its open-source nature. Different features have been added by different people over the years. It continues to evolve. The Linux operating system has been an excellent platform both for development and performance. With the recent advent of high-end, multichannel digital audio card support for Linux (e.g., the RME Digi96 series), the abilities of RTcmix grow in conjunction with the OS.

This article only scratches the surface of RTcmix's potential. Future articles will discuss in greater depth the process of writing RTcmix instruments and controlling them in real time (e.g., with nice open-source GUI packages like GTK).

In the end, it remains amazing to think that a computer, operating system and software package can work together well enough to make music. It is, however, by no means new thinking. Ada Lovelace apparently debated at length with Charles Babbage the virtues of this “new computing device”. His contentions had to do with an unbeatable chess player, hers about a device that could compose and create music of any type or degree of complexity.

David Topper (topper@virginia.edu) is the technical director for the Virginia Center for Computer Music at the University of Virginia. Linux has been his primary OS since downloading 40 floppies' worth of Slackware (kernel 1.0.9) as a CS undergrad. It is one of his firmest beliefs that the computer can be to the human mind and spirit what the telescope was to the ancient astronomers, provided free software like Linux continues to thrive.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
