章节摘录

版权页:   插图:   These applications and products require many interconnected complex steps, such as collection, processing, transmission, analysis, audio/display of real-world information in near real time.DSP technology has made it possible to incorporate these steps into devices that are inno vative, affordable, and of high quality (for example, iPhone from Apple,Inc.).A typical application to music is now considered as a motivation for the study of DSP. Musical sound processin,g In the music industry, almost all musical products (songs, albums, etc.) are produced in basically two stages.First, the sound from an individual instrument or performer is recorded in an acoustically inert studio on a single track of a multitrack recording device.Then, stored signals from each track are digitally processed by the sound engineer by adding special effects and combined into a stereo recording,which is then made available either on a CD or as an audio file. The audio effects are artificially generated using various signalprocessing techniques.These effects include echo generation, reverberation (concert hall effect), flanging (in which audio playback is slowed down by placing DJ's thumb on the flange of the feed reel), chorus effect(when several musicians play the same instrument with small changes in amplitudes and delays), and phasing (aka phase shifting, in which an audio effect takes advantage of how sound waves interact with each other when they are out of phase).These effects are now generated using digital-signal-processing techniques.We now discuss a few of these sound effects in some detail. Echo Generation The most basic of all audio effects is that of time detay, or echoes.It is used as the building block of more complicated effects such as reverb or flanging.In a listening space such as a room, sound waves arriving at our ears consist of direct sound from the source as well as reflected off the walls, arriving with different amounts of attenuation and delays. Echoes are delayed signals, and as such are generated using delay units.For example, the combination of the direct sound represented by discrete signal y(n) and a single echo appearing D samples later (which is related to delay in seconds) can be generated by the equation of the form(called a difference equation)

  •     非常经典的一本书,对于学习数字信号处理很有帮助
  •     学习matlab的好教材,可以提高英语水平
  •     这本书还是挺好的,讲的比较细致。
  •     英文版在国内买太实惠了,很有性价比
  •     matlab好教材,可以提高英语水平
  •     灰常灰常不错的书哦
  •     书挺好的。印刷也好
  •     一开始买这书挺激动的,后来发现图书馆有。当然还是有一本好,能很随意的做记号,对学习很有用。
  •     收到书后有点小失望,本书有如下缺点:1.纸很薄;2.删掉了原版中的第11章、第12章和Index部分;一看就知道是为了节约成本,但是书的卖的一点都不便宜,不建议大家买。
  •     我手里有这书的电子版,电子版672页,怎么这里的只有500多页,难道少了几章?本想收藏一本的,看来不敢下手了。
  •     很不错的书,讲述的很详细。可惜没有答案~~
