我在哪里可以找到低水平声音规划理论教程 [英] Where can I find low level Sound Programming Theory Tutorials

问题描述

我是一个中间的图形程序员。我想学习从地上爬起来音频/声音处理的理论。

I am an intermediate graphics programmer. I want to learn audio/sound processing theory from the ground up.

就像如何像素，其分量R，G，B，A是图形编程的基本组成部分。我想了解一下在类似的路线声节目。

Just like how "A pixel" and its components R,G,B,A is the fundamental part of Graphics programming. I want to know about sound programming in similar lines.

任何人都可以点我的良好的联系？此外，我想知道一些图书馆（preferably便携式），这让我来操纵声音。东西可以在MP3直接工作，AMR文件。

Can anyone point me to good links? Also I would like to know some libraries (preferably portable) which allow me to manipulate sound. Something which can directly work on mp3, amr files.

我不介意建议书太：）

推荐答案

让你的手脏了非常低的水平（C / C ++）之前，我建议用更高级别的工具，如的倍频（免费Matlab的克隆）。您可能需要安装信号处理工具包了。这应该给你一个很好的测试平台玩弄的FFT，卷积，过滤等等，还可以让你绘制的结果。我建议在信号处理找到一本好书，熟悉的概念，然后如果你想进入DSP算法， MusicDSP.org 是值得一试。

Before getting your hands dirty with the very low levels (C/C++) I'd suggest playing around with higher level tools such as Octave (a free Matlab clone). You might need to install the Signal Processing toolkit too. This should give you a good testbed for playing around with FFTs, convolution, filtering and the like, and also lets you graph the results. I'd suggest finding a good book on signal processing to get familiar with the concepts, then if you want to get into DSP algorithms, MusicDSP.org is worth a look.

如果您希望现有的框架一起工作再看看 CLAM 。

If you want an existing framework to work with then look at CLAM.

在图形编程像素是类似于音频单一取样点。数字化的图像是由像素的二维数组的;一个数字化的音频信号是由采样点的序列，每一个点correponding到的幅度。你会在书中找到休息...

A pixel in graphics programming is analogous to a single sampled point in audio. A digitised image is comprised of a 2d array of pixels; a digitised audio signal is comprised of a sequence of sample points, each point correponding to an amplitude. The rest you'll find in the books...
