Linux Sound Programming

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.

What You'll Learn

• Work with sampled audio

• Handle Digital Signal Processing (DSP)

• Gain knowledge of MIDI

• Build a Karaoke-like application

• Handle streaming audio

  Who This Book Is For
  Experienced Linux users and programmers interested in doing multimedia with Linux.

  Contains in-depth information on the Linux sound system Shows you how to build a Karaoke-like application in Linux Will teach you how to handle sampled and streaming audio in Linux

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.
