WebSep 16, 2024 · Draw the radius of the circle. The endpoints of the radius will be (0,0) and (r*cos a, r*sin a), where the point (r*cos a, r*sin a) will always be of the circle. Draw the sine curve. Then draw a line that will join the starting point of the sine wave and the endpoint of the radius of the circle. The length is called the gap for sake of simplicity.

WebMay 5, 2024 · update: np.sin function just like any sin function can only produce a sine wave (unless the argument is 0 or close to it, in which case you can get a straight line possibly due to numerical round-off errors). Note that np.sin accepts an angle as an argument so freq1 will be treated as an angle. WebAug 26, 2024 · How to plot sine wave in python 6 different ways 1. The NumPy library has a sin () method.

Web1 day ago · wave.open(file, mode=None) ¶. If file is a string, open the file by that name, otherwise treat it as a file-like object. mode can be: 'rb'. Read only mode. 'wb'. Write only mode. Note that it does not allow read/write WAV files. A mode of 'rb' returns a Wave_read object, while a mode of 'wb' returns a Wave_write object. WebDec 30, 2024 · 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.
