This book is your how-to guide for programming audio and sound for the Open Source Linux Operating System. Readers will learn how to utilize DSPs, sampled audio, MIDI, karaoke, streaming audio and more.
Linux is a major operating system that can not only do what every other operating system can do, but can also do a lot more. But because of its size and complexity it can be hard to learn how to do any particular task.
The Linux sound system is a major example of this: there is a large variety of tools and approaches for almost every aspect of sound. This ranges from audio codecs, to audio players, to audio support both within and outside of the Linux kernel.

What you´ll learn:

How to do sampled audio

What is and how to handle Digital Signal Processing (DSP)

How to do MIDI

How to build Karaoke like application

How to handle streaming audio and more
Who is this book for: Experienced Linux users and programmers interested in doing multimedia with Linux and perhaps even game development.

Program audio and sound for Linux using this practical, how-to guide. You will learn how to use DSPs, sampled audio, MIDI, karaoke, streaming audio, and more. Linux Sound Programming takes you through the layers of complexity involved in programming the Linux sound system. You´ll see the large variety of tools and approaches that apply to almost every aspect of sound. This ranges from audio codecs, to audio players, to audio support both within and outside of the Linux kernel.

Jan Newmarch is Head of ICT (Higher Education) at Box Hill Institute, Adjunct Professor at Canberra University and Adjunct Lecturer in the School of Information Technology, Computing and Mathematics at Charles Sturt University. He is interested in more aspects of computing than he has time to pursue, but the major thrust over the last few years has developed from user interfaces under Unix into Java, the Web and now into general distributed systems. Jan has developed a number of publicly available software systems in these areas. Right now, he is looking at sound for Linux systems and programming the Raspberry Pi´s GPU.
