生成的音效拿来做手机铃声，或者系统的音效，做 flash 素材都不错

面翻译一下界面上的英文，左边一排按钮是随机生成音效：

捡起/投币（PickUp/Coin）
激光/射击（Laser/Shoot）
爆炸（Explosion）
能量升级（PowerUp）
击中/受伤（Hit/Hurt）
弹开/选择（Blip/Select）
突变（mutate，生成当前音效的相似效果）
随机化（Randomizc）
上部的按钮是：方波（squarewave）、 锯齿波（sawtooth）、正弦波（sinewave）、
噪音（noise）。

中间的设置：

attack time - 增高时间
sustain time - 保持时间
sustain punch - 这个不知道怎么翻译。有谁知道？
decay time - 衰退时间
start frequency - 起始频率
min frequency - 最低频率
slide - 滑动？
delta slide - ？
vibrato depth - 颤音深度
vibrato speed - 颤音速度
change amount - 改变总数？
change speed - 改变速度？
square duty - ？
duty sweep - ？
repeat speed - 重复速度
phaser offset - 相位抵消？
phaser sweep - ？
lp filter cutoff - 低通滤波器截止频率
lp filter cutoff sweep - ？
lp filter resonance - ？
hp filter cutof - 高通滤波器截止频率
hp filter cutoff sweep - ？
右下角的按钮：

Play Sound - 播放
Load Sound - 载入声音文件(.sfs)
Save Sound - 保存为声音文件(.sfs)
Export .wav - 导出为声波文件

Basic usage:

Start the application, then hit
some of the buttons on the left
side to generate random sounds
matching the button descriptions.

Press "Export .WAV" to save the
current sound as a WAV audio file.
Click the buttons below to change
WAV format in terms of bits per
sample and sample rate.

If you find a sound that is sort
of interesting but not quite what
you want, you can drag some sliders
around until it sounds better.

The Randomize button generates
something completely random.

Mutate slightly alters the current
parameters to automatically create
a variation of the sound.

Advanced usage:

Figure out what each slider does and
use them to adjust particular aspects
of the current sound...

Press the right mouse button on a slider
to reset it to a value of zero.

Press Space or Enter to play the current sound.

The Save/Load sound buttons allow saving
and loading of program parameters to work
on a sound over several sessions.

Volume setting is saved with the sound and
exported to WAV. If you increase it too much
there's a risk of clipping.

Some parameters influence the sound during
playback (particularly when using a non-zero
repeat speed), and dragging these sliders
can cause some interesting effects.
To record this you will need to use an external
recording application, for instance Audacity.
Set the recording source in that application
to "Wave", "Stereo Mix", "Mixed Output" or similar.

Using an external sound editor to capture and edit
sound can also be used to string several sounds
together for more complex results.

Parameter description:
- The top four buttons select base waveform
- First four parameters control the volume envelope
Attack is the beginning of the sound,
longer attack means a smoother start.
Sustain is how long the volume is held constant
before fading out.
Increase Sustain Punch to cause a popping
effect with increased (and falling) volume
during the sustain phase.
Decay is the fade-out time.
- Next six are for controlling the sound pitch or
frequency.
Start frequency is pretty obvious. Has a large
impact on the overall sound.
Min frequency represents a cutoff that stops all
sound if it's passed during a downward slide.
Slide sets the speed at which the frequency should
be swept (up or down).
Delta slide is the "slide of slide", or rate of change
in the slide speed.
Vibrato depth/speed makes for an oscillating
frequency effect at various strengths and rates.
- Then we have two parameters for causing an abrupt
change in pitch after a ceratin delay.
Amount is pitch change (up or down)
and Speed indicates time to wait before changing
the pitch.
- Following those are two parameters specific to the
squarewave waveform.
The duty cycle of a square describes its shape
in terms of how large the positive vs negative
sections are. It can be swept up or down by
changing the second parameter.
- Repeat speed, when not zero, causes the frequency
and duty parameters to be reset at regular intervals
while the envelope and filter continue unhindered.
This can make for some interesting pulsating effects.
- Phaser offset overlays a delayed copy of the audio
stream on top of itself, resulting in a kind of tight
reverb or sci-fi effect.
This parameter can also be swept like many others.
- Finally, the bottom five sliders control two filters
which are applied after all other effects.
The first one is a resonant lowpass filter which has
a sweepable cutoff frequency.
The other is a highpass filter which can be used to
remove undesired low frequency hum in "light" sounds.
