Hi, I have a simple task I can't figure out. I'd like to take some measurements I made, e.g.: year (y-axis) 1 2 3 4 5 6 counts (x-axis) 10 10 20 30 40 50 And then, make a barplot with the x-axis ticks (representing the borders between years) between the bars. However, barplot seems to force you to make the x-axis arbitrary categories. I want it to be continuous (as in a

...-6 khz area, but I blame that on the headphones; they're cheap. However, when switching to AC DC: Big Gun, we see and hear a large residual echo from the opening el-guitar. This seems to be a result of a semi-stable sound that lasts more than 20 ms; the canceller finds a correlation in 4-5 timebins instead of just one. We could reproduce the same result by playing a human voice saying "aaaaaaaaaa" without variation in pitch; the weights for those frequency bins would increase for all the timeslots in W. Now, people don't say "aaaaaaaaaaaaa" all that often, but the...

Hi, I'm still working on visualizing the echo canceller, but I discovered something that might be interresting. During testing, i did this: Generate a test signal (10+x sine waves per frame), where x increases by one for each iteration, and wraps around at 100. Set the speaker signal for the frame to the test signal. Add 0.5*test signal to the mic signal. When watching the power graph
