[paper reading] 1992 Sound rendering

1992年SIGGRAPH上发表的《SoundRendering》奠定了图形学中声音渲染的基础。文章提出soundrendering概念,分析声光差异,给出声音合成框架,强调基于物理声音建模。研究分三阶段:初态声音合成、声音实例化及声音传播。

《Sound Rendering》这篇论文发表在1992年SIGGRAPH上,感觉是图形学中声音渲染的奠基性工作。

文章提出了一种用于动画同步音轨合成的通用方法。总结几点如下:

  • 提出了sound rendering 的概念:The process of forming the composite soundtrack from component sound objects.
  • 分析了sound 和light 的区别。主要由于propagation speed 和 wavelength 不同而导致的延迟的明显度不同,声波会有明显的回声,混响等现象。
  • 给出了声音合成框架,下图所示
  • 后续二十几年的文章几乎都可以套进这个框架中。其中prototype sound我认为可以翻译为初态声音,文章中也提到可以合成,也可以采用用户提供的录音样本。后续的基于物理声学模型,基于模态合成或者数据驱动的声音合成方法,感觉本质上都是在改变初态声音的合成方式。
  • sound event script 是用来产生与动画运动同步的声音这篇文章把这个过程称为sound instantiation,或许可以翻译为声音实例化,即把初态声音调整为和动画中的某个物体对应关系。
  • 后半部分sound rendering 更像是目前的声音传播工作,更多是侧重声线与整个动画环境的交互(反射,衍射等现象)。
  • 在这篇文章中,作者将动画中的运动其实分为了三类:keyframing,behavioral 和 physically-based。不过后续的研究,包括作者在总结中也写到,要侧重于研究更严格的基于物理声音建模。

读完感觉挺奇妙的,原来在图形学领域,最开始的研究思路也是提出一个统一的框架来合成不同类别的声音,只不过从2001年开始研究者就开始侧重于某一类特定的声音类别,大多是一篇文章主攻一种声音。

或许,分久必合。

I have played the game Chrono Cross but out of all of the games I have ever played it has the best music! It backs away from crude keyboarding and takes a fresher step with grate guitars and soulful orchestras. It would impress anyone who cares to listen! ^_^ 0 2 The best soundtrack ever to anything. I'm reading a lot of reviews saying that this is the best 'game soundtrack' and I figured that I'd write a review to disagree a bit. This in my opinino is Yasunori Mitsuda's ultimate masterpiece. The music is timeless and I'm been listening to it for years now and its beauty simply refuses to fade.The price tag on this is pretty staggering I must say, but if you are going to buy any cd for this much money, this is the only one that I feel would be worth every penny. 1 2 Amazing! "This soundtrack is my favorite music of all time, hands down. The intense sadness of ""Prisoners of Fate"" (which means all the more if you've played the game) and the hope in ""A Distant Promise"" and ""Girl who Stole the Star"" have been an important inspiration to me personally throughout my teen years. The higher energy tracks like ""Chrono Cross ~ Time's Scar~"", ""Time of the Dreamwatch"", and ""Chronomantique"" (indefinably remeniscent of Chrono Trigger) are all absolutely superb as well.This soundtrack is amazing music, probably the best of this composer's work (I haven't heard the Xenogears soundtrack, so I can't say for sure), and even if you've never played the game, it would be worth twice the price to buy it.I wish I could give it 6 stars." 2 2 Excellent Soundtrack I truly like this soundtrack and I enjoy video game music. I have played this game and most of the music on here I enjoy and it's truly relaxing and peaceful.On disk one. my favorites are Scars Of Time, Between Life and Death, Forest Of Illusion, Fortress of Ancient Dragons, Lost Fragment, and Drowned Valley.Disk Two: The Draggons, Galdorb - Home, Chronomantique, Prisoners of Fate, Gale, and my girlfriend likes ZelbessDisk Three: The best of the three. Garden Of God, Chronopolis, Fates, Jellyfish sea, Burning Orphange, Dragon's Prayer, Tower Of Stars, Dragon God, and Radical Dreamers - Unstealable Jewel.Overall, this is a excellent soundtrack and should be brought by those that like video game music.Xander Cross 3 2 Remember, Pull Your Jaw Off The Floor After Hearing it If you've played the game, you know how divine the music is! Every single song tells a story of the game, it's that good! The greatest songs are without a doubt, Chrono Cross: Time's Scar, Magical Dreamers: The Wind, The Stars, and the Sea and Radical Dreamers: Unstolen Jewel. (Translation varies) This music is perfect if you ask me, the best it can be. Yasunori Mitsuda just poured his heart on and wrote it down on paper. 4 2 an absolute masterpiece I am quite sure any of you actually taking the time to read this have played the game at least once, and heard at least a few of the tracks here. And whether you were aware of it or not, Mitsuda's music contributed greatly to the mood of every single minute of the whole game.Composed of 3 CDs and quite a few songs (I haven't an exact count), all of which are heart-rendering and impressively remarkable, this soundtrack is one I assure you you will not forget. It has everything for every listener -- from fast-paced and energetic (Dancing the Tokage or Termina Home), to slower and more haunting (Dragon God), to purely beautifully composed (Time's Scar), to even some fantastic vocals (Radical Dreamers).This is one of the best videogame soundtracks out there, and surely Mitsuda's best ever. ^_^
