Optimized with TDSI. Got nice performance while processing pitch shifting and time stretching.

Current implemented:

Load and play accessable mp3 bit stream.

Wrapped AudioX class.Realtime sound speed controlling as buildin property(non-resampleing pitch shift), realtime pitch

shift as filter(no time stretching).

Several filters, including, Biquad,3bands EQ, stereo rot, stereo width range, cutoff, notch, phase, wave record, pitch

shift, etc.

Generators implemented: env, square, triangle, saw, sin, pink noise, white noise.

Analyzers implemented: FFT, BeatDetector.

Integrated Midas3 for parsing standard midi file. Will play midi file in the future.

Currently on our site www.duobiduo.com, audio remix RIA's realtime changeing speed function is powered by the early version of this lib.

Future features:

More filters.

Optimized core framework.

Over 32 channels sound together, which is limited by flashplayer.

Small and normal quality wave-table for midi playing.

More visualizations.

Soft sound effects sources.

经过TDSI的代码注入技术优化,在变调变速运算时能获得满意的性能。

目前已经实现的功能有:

flash播放可访问比特流mp3音频。

重新封装的AudioX类。音频实时播放变速不变调(no pitch shift)作为默认属性,滤镜方式音频实时播放变调不变速(no strenth)。

同时还实现了若干滤镜,包括Biquad,3档EQ,立体声反转,立体声域调节,cutoff,嵌波,相位调节,wave录制,变调保速,等等。

已经实现的音源发生器包括:包络发生器,方波,角波,锯齿波,正弦波,粉红噪音,白噪音。

已经实现的分析器包括:FFT,节拍检测。

同时还整合了Midas3,用于对标准midi文件解析,计划实现flash实时播放midi文件。

目前多比多(www.duobiduo.com)网站的混音RIA的实时变速功能就应用了该库的早期版本。

计划给这套代码增加更多的内容,包括:

更多的效果滤镜。

优化核心架构。

超过flash内置的32路音频限制。

小巧中等品质的软波表用于实时midi播放。

视觉效果。

软特效声源。
