 Audio Development
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.
- MATLAB 7.0 commercial software for algorithmic design, developement, engineering, and scientific computing. (multi-platform support)
- 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)
- 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 analysis, filters, effects and synthesis. (C, C++, and Java code)
- HRTF A database of measurements and research papers on Head Related Transfer Functions for 3D-Audio. (PDF, Audio)
- MIDI Specifications MIDI 1.0, the new MusicXMF specification, and SP-MIDI for third generation 3GPP mobile devices (PDF)
- OpenAL a beginners tutorial on writing code using OpenAL for audio programming in computer games and other applications. (C, C++).
- 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.
- 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)(PDF)
- Vector Quantization authors Gersho and Gray. Good read for understanding how VQ and arithmetic coding work.
