用于扬声器/耳机音频输出的双通道功能/波形/信号发生器。

没有广告,没有权限,没有应用内购买,没有限制功能。完整版。

每个左右声道的输出为16位,频率为44.1kHz。输出取决于您的设备硬件。一些设备硬件可以滤除DC偏置和低频信号。在高频时,由于每个波形的采样数量有限,波形将会失真(例如,在4.41kHz时,正弦波形将仅近似10个点)。因此,这是为了娱乐/教育用途,关键应用程序使用真正的校准函数发生器。

左右音频通道可以分配给通道1或通道2.
Sine,Square&三角波形。
频率范围从1 mHz到22 kHz。
幅度百分比0-100%。
设置方波占空比或偏斜三角波形以获得锯波形。
偏移相位波形。扫描频率或幅度(单次,重复和反射模式)。
幅度调制(AM)。
频率调制(FM)。
特定波形数量的突发模式( 1-10000)。
白噪声&粉红噪声发生器。粉红色(1 / f)噪声在43 Hz和44 kHz之间下降到每倍频程~3dB。
内存插槽保存&调用通道配置。
使用弹簧滑块或数字键盘选择值。

Dual channel function / waveform / signal generator for the speaker / headphone audio output.

No Ads, No Permissions, No In App Purchasing, No Limited Features. Full Version.

Output is 16 bit for each left and right channels and at 44.1kHz. Output will depend on your device hardware. Some device hardware may may filter out the DC bias and low frequency signals. At high frequencies, the waveforms will be distorted due to limited number of samples for each waveform (for example at 4.41kHz, a sine waveform will be approximated by only 10 points). Therefore this is for fun/educational use, for critical applications use a real calibrated function generator.

Left and Right audio channels can be assigned to either channel 1 or channel 2.
Sine, Square & Triangular waveforms.
Frequency range from 1 mHz up to 22 kHz.
Amplitude as percentage 0-100%.
Set duty for square waveforms or skew triangular waveforms to get saw waveforms.
Offset the phase of waveforms.
Sweep frequency or amplitude (Single, Repeat & Bounce modes).
Amplitude Modulation (AM).
Frequency Modulation (FM).
Burst mode for a specific number of waveforms (1-10000).
White noise & pink noise Generator. Pink (1/f) noise falls of at ~3dB per octave between 43 Hz and 44 kHz.
Memory slots to save & recall channel configuration.
Select values with spring slider or number pad.

添加设置(左上方的齿轮按钮) - 现在可以更改频率,幅度,相位和占空比分辨率。设置还有一个软开启/关闭选项,以避免那些恼人的“点击”。添加了一个简短的用户指南(i按钮右上角)。再加上一些小调整/修正。

Added settings (cogs button top left) - Frequency, Amplitude, Phase and Duty Resolution can now be changed. Settings also has a soft turn on/off option to avoid those annoying 'clicks' . Added a short user guide (i button top right). Plus a few more minor tweaks/fixes.
