什么软件可以创作声音,主要可以定义声音的频率,连续播放

goldwaveGoldWave不但有完善的声音编辑功能,还有强大的声音生成功能,你可以使用一些数学公式来生成各种各样的声音。选定插入点后,点击工具栏上的表达式求值器f(x)按钮,即可进入表达式求值器窗口进行修改。你也可以直接在Expression文本框中直接输入表达式来产生声音。例如,你可以输入类似sin(t)*log(t)-exp(t)这样的表达式。到这里,我们已经介绍了GoldWave的基本功能,GoldWave是一个功能很强大的软件,使用起来也很方便,只要你经常使用她,一定会发现更多的功能和优点。学习时使用中文版,如果没声音文件基础知识,按照上述方法将基本功能学习后,其它高级功能试着用一用,反正不行大不了来个“Undo”。Dial tones:#:(sin(5912*t)+sin(9280*t))/2 * :(sin(5912*t)+sin(7596*t))/2 0:(sin(5912*t)+sin(8394*t))/2 1:(sin(4379*t)+sin(7596*t))/2 2:(sin(4379*t)+sin(8394*t))/2 3:(sin(4379*t)+sin(9280*t))/2 4:(sin(4838*t)+sin(7596*t))/2 5:(sin(4838*t)+sin(8394*t))/2 6:(sin(4838*t)+sin(9280*t))/2 7:(sin(5353*t)+sin(7596*t))/2 8:(sin(5353*t)+sin(8394*t))/2 9:(sin(5353*t)+sin(9280*t))/2 987-6543:(sin(5353*t)+sin(9280*t))/2*(step(t-。1)-step(t-。22))+(sin(5353*t)+sin(8394*t))/2*(step(t-。3)-step(t-。42))+(sin(5353*t)+sin(7596*t))/2*(step(t-。5)-step(t-。62))+(sin(4838*t)+sin(9280*t))/2*(step(t-。7)-step(t-。82))+(sin(4838*t)+sin(8394*t))/2*(step(t-。9)-step(t-1。02))+(sin(4838*t)+sin(7596*t))/2*(step(t-1。1)-step(t-1。22))+(sin(4379*t)+sin(9280*t))/2*(step(t-1。3)-step(t-1。42)) A:(sin(4379*t)+sin(10260*t))/2 B:(sin(4838*t)+sin(10260*t))/2 C:(sin(5353*t)+sin(10260*t))/2 D:(sin(5912*t)+sin(10260*t))/2 Effects:Amplitude modulation(振幅调制):wave(n)*cos(2*pi*f*t) Bender(弯音):wave(n+(1/T/16)*(sin(2*pi*t)+1)) Echoes,x=delay,y=volume(回声,x=延迟,y=音量):wave(n)+wave(n-(1/T)*x)*y Envelope detector(包络检测):(wave(n)>wave(n-1))*(wave(n)*0。1+wave(n-1)*0。9)+(1-(wave(n)>wave(n-1)))*(wave(n-1)*0。99) Frequency modulation(频率调制):cos(2*pi*f*t + y*wave(n)) Tremolo(震音):wave(n) * (0。6 + 0。4 * sin(2*pi*f*t)) Harmonics:Chord 1(和弦 1):0。3*sin(2*pi*t*f)+0。3*sin(2*pi*t*f*1。2599)+0。3*sin(2*pi*t*f*1。4983) Chord 2(和弦 2):0。3*sin(2*pi*t*f)+0。3*sin(2*pi*t*f*1。3348)+0。3*sin(2*pi*t*f*1。6818) Even and equal(偶数并相等):(sin(2*pi*t*f)+sin(2*pi*t*f*2)+sin(2*pi*t*f*4)+sin(2*pi*t*f*6))/4 Odd and equal(奇数并相等):(sin(2*pi*t*f)+sin(2*pi*t*f*3)+sin(2*pi*t*f*5)+sin(2*pi*t*f*7))/4 Music Twinkle on xylophone(木琴演奏):(sin(2*261*pi*t)*(step(t)-step(t-1))+sin(2*392*pi*t)*(step(t-1)-step(t-2))+sin(2*440*pi*t)*(step(t-2)-step(t-3))+sin(2*392*pi*t)*(step(t-3)-step(t-3。5))+sin(2*349*pi*t)*(step(t-4)-step(t-5))+sin(2*329*pi*t)*(step(t-5)-step(t-6))+sin(2*293*pi*t)*(step(t-6)-step(t-7))+sin(2*261*pi*t)*(step(t-7)-step(t-7。5)))*(1-2*abs(1-2*。5*t%。5)) Noise Add hiss to wave(给波形添加嘶嘶声):wave(n)+(rand(2*y)-y) Brown(褐噪):limit(wave1(n-1)+rand(0。5)-0。25):Brown softer(褐噪 柔和):(wave1(n-1)+rand(0。1)-0。05)*0。99 Fuzzy sound(模糊声音):wave(n + rand(2)) Jet(喷气):limit(wave1(n-1)+(rand(0。05)-0。025)-(wave1(n-2)+(rand(0。05)-0。025))) Vinyl,x and f=pop,y=hiss(唱片,x和f=爆破音,y=嘶嘶声):wave(n)+(rand(x)*(rand(1/T/f)
