Assuming it was the KZfaq algorithm whom deleted my comment from days ago and not Frank (since it contained a jsfiddle link): you can achieve the "drawing" effect in the begging by using a combination of stroke-dashoffset, and stroke-dasharray to a number that makes the SVG invisible (e.g.: 2000/2000, depends on the image), then animate the stroke-dashoffset to 0, using CSS3.

@mixtapeverse1184 video encoding is a complicated topic that I'm not an expert in. I dont think JavaScript is the best tool for that, but it might be possible. Maybe there is a library to make it easy. I would have to research it. Personally I would just play it on a big screen and record it in high resolution. Screen recorders have settings where you don't lose any quality. This goes beyond my expertise. Let me know if you come up with a solution

Hi. Mobile audio has many limitations.

Hi, if it's remaining black there is a problem with your fillStyle call, either wrong syntax on that line or you are calling it from a different place than I did. fillStyle is a single property on canvas object that gets overwritter easily.

Hi, thanks for the tutorial. How to calculate the number of seconds (or say milliseconds) for which volume function calculated the average volume? I understand it depends on the the value of fft size, but difficult to figure out the span of time.. thanks!
@Frankslaboratory2 жыл бұрын
Hi. Since we are calculating volume value every animation frame all we need is delta time value to see how many milliseconds each frame lasts. If your app refreshes 60 times per second volume is calculated every 16.6 milliseconds. Maybe I misunderstood your question. If so let me know :)
@Frankslaboratory2 жыл бұрын
I think volume is calculated for that particular moment. There is no time span. Now we are going a bit too deep under the hood. I dont know complete ins and outs of fft algorithm. I will research it better for the next video
@InfinitelyAmplified2 жыл бұрын
Would there be anyway to take that (fftsize/2) in the for loop in the createBars function and set it to a range input so you could update the number of bars live? I've gotten it to work but I have to refresh the page each time for it to go through createBars() and animate() to update the number of bars. Thanks.
@Frankslaboratory2 жыл бұрын
There are many ways to do that. I would probably do public setter method on microphone class that takes values from a drop down since fftSize needs to be a set of very specific values. Then I would attach it to an event that empties bars array and calls createBars again to replenish it with new set of audio bars
