Able to reproduce this issue on Windows-10, Ubuntu 14.04 and Mac OS 10.12.6 using chrome latest stable #60.0.3112.90 by following steps mentioned below.

1. Navigated to the test URL: www.bnaturalmusicrepair.com:8087 
2. Creates a New Project
3. Clicked on 'Use computer keyboard to play' and Use Tuner'
4. Played some music using keyboard keys
5. Observed some random clicking sound while playing

Tested this issue on older version of chrome M45-45.0.2454.101 as well and issue is observed, Hence marking it as untriaged.

Thanks!

brajkumar@ Are there more steps than this? Using your steps, I hear no audio at all. When I press the "Use tuner" button, I do hear audio then. Pressing and holding a key does seem to cause some clickyness, but I can't tell if that's a bug in webaudio or the expected result since I don't really know what it should sound like.

Also, danhandman@, this demo is so huge it's really hard to figure out what could be wrong.  It would be really great if you create a smaller demo that shows the problem.  Or maybe point out where all the code is that uses webaudio.

OK I made a quick and easy program to show that problem it will just produce a sound and if you let it play for like 30 seconds you will hear the clicking random sounds.  www.bnaturalmusicrepair.com:8094

Thanks for the much simpler demo.  It really helps a lot!

I tried this on my Linux box running Chrome 61.0.3163.31.  It took quite a while before I could hear any clicks.  And only a few when I tried to open the menu (3 dots) to get the Chrome version.  No more clicks after that.

What kind of machine are you testing this on?  (Although that shouldn't matter too much.  A simple oscillator and gain node should run without glitching even on an ancient Galaxy Nexus.)

Im runing a 2 core 2.7 amd 8g of ram and ssd its an acer travelmate.  But it also does it on my surface 1 pro.  After digging more into it it seems to happen when u have cpu activity like u said clicking on the dots made the disruption in sound.  The weird thing is that this is a recent change it was not like this last month.  

Thanks for the info.

Not sure what's going on.  Definitely didn't click like this before with a simple oscillator.  It's going to take some digging to figure out what's happening.

Well at least im not crazy.

Based on this comment, I suspect this might be a dupe of the issue 745898.

Ok well I can't view issue 745898 so i'll just wait for it to be resolved.   Thanks again

I figured something out that might be helpful.  In windows 10 the cpu is throttled back as the cpu usage drops and is throttled up as cpu usage increases.  I noticed that when I make it so window 10 can not throttle the cpu and it keeps it at the same GHZ the clicking sounds practically don't happen.  and when I let the cpu throttle it down the clicks happen very often. hopefully this will help

Not much we can do if the OS throttles the CPU causing glitches.

Ran this again on linux using www.bnaturalmusicrepair.com:8094 and Chrome 64.0.3282.99.  Don't hear any glitches at all.

No issues on win10 with Chrome 63 either.

Can you retry with Chrome 63 or later?
