How can I generate a sine wave with time varying frequency that is continuous, in C? Ask Question. Asked 1 year, 11 months ago. Active 1 year, 11 months ago. Viewed 10k times. Improve this question. The OP's attempted solution is not a varying frequency, but a changed one. All that needs to be done for that is to make sure the signal is continuous at the junction by picking the correct phase offset.

Smoothness can be achieved by a small overlap and a sliding average. For a varying frequency the answer is simpler. Just use a non-linear function in your trig argument. A quadratic is the next easiest one. Each has interesting useful properties. Add a comment. Active Oldest Votes. Improve this answer. The OP's code can be fixed with the addition of one line of code between the two loops and a modification to one line in the second loop.

I'm not going to code it, but simply set a variable for the phase offset at the junction and add it into the argument in the second loop. I just chimed in to make a distinction between "varying" from the title and "change in" from the code example.

The extra divides and type conversions you pay may not be worth it, nor a bunch of extra function calls. On a side note, your code would benefit by replacing your divides with multiplications of their stored reciprocals. Mass funeral prayer to be held for Bronx fire victims.
