• Timidity++ (MIDI to PCM (WAV) converter. Timidity++ synthesizes MIDI files (sequences) in real-time using Gravis UltraSound Soundfont patches (loosly based upon Wavetable Synthesis) to common digital audio file formats such as, WAV, AU, AIFF, Ogg Vorbis, FLAC, etc. Useful for those who want to bypass FM Synthesizers on their sound card's to hear MIDI sequence as it was intended to be heard.)

Audio Development

Getting Started

note: Let's start with basic development tools (compilers, engineering tools, dev. libraries) until we think of more tools to add. I am also adding external links to books, tutorials, etc under resources.

Tools

• MATLAB 7.0 commercial software for algorithmic design, developement, engineering, and scientific computing.
• GNU Octave open-source alternative software (GPL) to MATLAB for numerical computations, engineering, and scientific computing. (multi-platform support)
• FFTW Is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions on real and complex inputs.
• GCC THE GNU compiler collection for C, C++, Objective-C, Fortran, Java, and Ada.
• GNU Emacs an extensible, customizable, self-documenting real-time display editor. Great for writing all types of source code especially on Unix. (multi-platform support)
• DevCPP free front-end IDE and compiler for the C and C++ languages. Delphi and C source code available. (Win 9x, NT, 2000, and XP)

Resources

• Scientific/R&D Forums for Psychoacoustic, DSP, Electrical Engineering, theory, and coding related questions. (most questions are generally answered)
• AES The Audio Engineering Society website. Home of year-round world AES conferences.
• DSP Tutorials this site provides another good introduction in to the area of DSP.
• Music-DSP source-code archive for anaylsis, filters, effects and synthesis. (C, C++, and Java code)
• ALSA Project (Advanced Linux Sound Architecture) bringing audio and MIDI capabilities to Linux.
• A Really friendly guide to Wavelets A good introduction to wavelets aimed towards engineer, requires a fair amount of background knowledge.

Books/Research

• Psychoacoustics - Facts and Models author's Zwicker, Fastl, and Hugo, revised 2005 third edition. The book for comprehensive psychoacoustics models and figures.
• Perceptual Audio Coding authors A. Painter and T. Spanias. A comprehensive paper on percepual audio coding (PDF)
• Speech Communications Human and Machine this book provides a good introduction to speech coding, inlcuding anaylsis, recognition, and perception. This text is a very good introduction for beginners.
• Scientist and Engineer's Guide to DSP author Steve Smith, a great guide for beginners new to the subject of DSP (free online text)
• Vector Quantization authors Gersho and Gray. Good read for understanding how VQ and arithmetic coding work.

Audio Resources

Websites

Note: Let's include a small description to the side for now, so that we have something to work with when this section becomes large enough for its own page

• http://www.audiocoding.com (Page with a wiki on technical audio topics, homepage of FAAC and FAAD2, also has an AAC forum.)
• http://www.ff123.net (Lots of general information on various MP3 implementations, test samples, testing methodology information, homepage of ABC/HR)
• http://www.head-fi.org (general information/board about head phones and portable audio players)
• http://www.rarewares.org (Downloads for many audio and media tools)
• http://www.rockbox.org/ (Open-source jukebox firmware for numerous DAP and architectures, GNU/GPL Liscense).
• http://psplab.csie.nctu.edu.tw/invboard2_0/index.php (Perceptual Signal Processing Lab, small university forum based in Tawain dealing with perceptual coding on acedemic level).
