kandi X-RAY | polyphony Summary
Polyphony is a library for building concurrent applications in Ruby. Polyphony harnesses the power of Ruby fibers to provide a cooperative, sequential coroutine-based concurrency model. Under the hood, Polyphony uses io_uring or libev to maximize I/O performance.

QUESTION
I have used Audiokit's both AKAppleSequencer and AKSequencer for 2 years now. This is my first iteration getting used to the new V5 version of the library. For whatever reason, I cannot get more than a single note to play simultaneously.
Below is a very simple example of what I am trying to do:
...ANSWER
Answered 2021-Feb-13 at 04:30According to the AudioKit team, this is not intended behavior and is being looking: https://github.com/AudioKit/AudioKit/issues/2409

I am pretty new to PHP and JSON. I am currently creating a website which has a ranking table for video games. I have created a JSON file with all the information in it:

usort($data, function($a, $b) { //Sort the array using a user defined function
return $a->rating > $b->rating ? -1 : 1; //Compare the scores
});
file_put_contents("data/json/mynewfile.json", json_encode($data));
QUESTION
I'm writing a basic synth at the moment and have run into a bit of a strange problem. I get a constant popping sound while playing an array of bytes, representing 16 bit mono audio, through a SourceDataLine.
The pops play at a constant rate, and from what I can hear, pitch. The pops do slightly differ in frequencies though (again, from what I can hear), some notes have low-passed sounding pops, and others sound high-passed. The pops are not overriding though, you can still hear the desired sound in the background.
Nothing changes the rate of the pops, not note pitch, not the SourceDataLine buffer size, not the number of bytes I write to it at a time, except sample rate.
Lowering the sample rate decreases the rate of the pops and vice-versa.
To test my side of the program, I printed out the data being written to the SourceDataLine for about half a second and looked through around 15 cycles of the played sine wave, and it was completely fine; no sudden jumps, clipping, or anything else.
The only two things I use the value of the sample rate for is some basic math to help my sampler sample at the correct frequency, which is only calculated once for each note, and is definitely working as pitch is perfect, and for creating the SourceDataLine.
Here's how I'm starting the SourceDataLine (Taken from multiple parts of the main method):
...ANSWER
Answered 2020-Jan-24 at 04:29Well as it turns out, the problem was completely unrelated to what I thought it might be.
Turns out there was a single equation I had written in my sampler that was just blatantly wrong.
After 2048 samples had been played, I would just kinda loop back to the beginning of the waveform, causing the popping.
I honestly have no idea why I wrote that in, but hey, it works now.
