trigonometry - sine wave generation in c++ - Stack Overflow
2018年5月16日 · I am trying to generate a set of points, which when plotted as a graph represent a sine wave of 1 cycle. The requirements are : a sine wave of 1 cycle; lower limit = 29491; upper limit = 36043; no of points = 100; Amplitude = 3276; zero offset = 32767; Code :
Generate sine signal in C without using the standard function
2017年12月20日 · Unfortunately, this function sometimes returns values far bigger than 1. Furthermore, the interpolation doesn't seem to be good (I used this to create sine shaped brightness changes of a LED, but these are very unsmoooth). Does anybody have a better idea to implement a sine generator in C?
How do I generate a sine wave using Python? - Stack Overflow
2017年12月31日 · I'm trying to generate a sine wave of a given frequency for a given duration and then write it into a .wav file. I'm using numpy's sin function and scipy's wavfile function. I'm getting a weird sound that is definitely not a sine wave.
performance - Endless sine generation in C - Stack Overflow
2021年10月26日 · A small deviation from the sine frequency (like 280.1Hz) would be ok. In that case, with a control interval of 30 µs, if you have a table of 119 samples that you repeat over and over, you will get a sine wave of 280.112 Hz. Since you have a 12-bit DAC, you only need 119 * 2 = 238 bytes to store this if you would output it directly to the DAC.

2011年11月28日 · ivan-onys gave an excellent answer, but there is a little addition to it: this script will produce 4 times shorter sound than expected because Pyaudio write method needs string data of float32, but when you pass numpy array to this method, it converts whole array as entity to a string, therefore you have to convert data in numpy array to the byte sequence yourself like this:
