First Aid Instructions If Glitchy Playback in the App

Since the App is not running inside a plugin anymore (Flash), we have to face many more dependencies which can potentially lower the experience in terms of performance. In order to rule out common issues here is a list of things to check before getting too angry about it.

First Things First

  • Is the latest version of Chrome installed? Current version is 70. Check > chrome://settings/help (copy and paste into the address-bar)
  • Make sure you clear your browser's cache
  • How many browser tabs do you have opened? (The less the better)
  • Try running the App in incognito mode to exclude extensions from creating possible interferences
  • Quit background software such as Skype, WhatsApp, Dropbox, Slack, etc.
  • Check your Task Manager (Win) or Activity Monitor (Mac) for cpu consuming, potential unnecessary processes
  • Make sure you have enough available disk space on your machine
  • Check the sample rate (Should not be higher than 48kHz, often 44.1kHz)
  • Try enabling Audio Worklet in the preferences in the App
  • Try lowering the FPS in the preferences in the App
  • If you are running a very high screen resolution, make the browser window smaller
  • Try Audiotool Booster
  • Nothing helps? Create a topic in (link is only visible to registered users)

The Way you Build your Track

We often see arrangements with questionable effect chains where a bunch of devices can just be removed or merged without changing the sound in the mix. In an ideal world, you should not bother, but every device on the desktop is taking valuable time from your CPU. Here are some things to consider.

  • Any combination of Stereo-Detune and Stereo-Enhancer can often be merged into one.
  • Compressors can give you the temporary illusion that the sound is more powerful. Try to bypass them once in a while to see if they are all necessary. Sometimes it is enough just to increase the volume to get the same effect.
  • Quantum as a Multiband-Compressor is mainly useful for mastering and to smooth out edges on very complex sounds. If you do not need the bands, replace it with Gravity, which needs way less CPU.
  • When using Curve, switch off the filters you do not work with.
  • Try to make your setting more compact. The longer the cable the more pixels needed to be drawn.
  • Switch off the spectrum analyser on Quantum and Curve once you've adjusted your settings.

      Everything is back to normal.

      It doesn't help to place this on the wrong board in a language that most people here don't understand (easily).

      As @Known As I said: You should reply to my comments or even better file a new bug-report. I know it is annoying when something does not work properly, but we are facing very new issues with Audiotool in html now that need a much deeper conversation to find a solution.

    Yes i am sure of Java 64bit it's installed.

    What do you mean by audioworklet?

      In the preferences you can see if 'AudioWorklet' is enabled (checked). It is a technology that should compute the audio in its own thread, hence less glitches. We figured however, it is not perfect yet, but it is up to the browser vendors to come up with a better solution. Hint: I know they are ;)

      Also, I saw on your wall that your booster does not connect. Are you 100% sure that you have Java 64bit installed?

      It is unfortunate, but you really need to provide more details on your system and machine. Otherwise there is no way to help you. If you cannot change the output device it is up to the PortAudio library we use to list your audio-devices. We could report a bug over there. But I am more interested in why and with what setup it glitches without the booster first.

    My audio tracks lag a LOT, I have nothing but AT Next running in an incognito browser on Windows 10. I opened my Task Manager and when I hit PLAY to listen to my track, which consists of the Machiniste (only one pattern) & Centroid (added a piano loop), the CPU on my computer instantly jumps to 99% usage.

    I have the Booster running on my system tray.

    I enabled the audio worklet (no idea what thats supposed to do but someone suggested it).

    I enabled lower FPS and even disabled animation.

    I shrunk the window as small as possible, it only covers 1/4 of my desktop.

    However, I have noticed that when I minimize the page, or switch to this tab to check the boards, the track clears up and plays at full speed. Its only when I'm viewing the workspace that the music slows and skips.

    I'm not quite sure if I added this in hopes of finding help or in the off chance my tricks might help someone else, but anyways that's my 2 cents.

      @InfiniteShadoe I feel your pain, but unless we have all systems available up and running, it is very hard to put our fingers on the problem. Chrome already gives us headaches. With each update we are trembling what they fixed or broke this time. It is rarely getting any better. They are bold things we can do in future to support the latest fancy web-technologies such as WebAssembly, but we need way more resources for that.

      One question still: Are you sure the booster is actually connected to the app? The icon should light up and the first context-menu entry should reflect that it is indeed connected.

    I have added some tips when building massive tracks. Please feel free to add more in the comments if you find other ways to improve the stability of the App.

    I've been getting really bad stuttering on a big track. I just tried playback with the timeline fully exposed (no dashboard showing ) and the app worked great. Not one stutter or skip.

    "Check the sample-rate (Should not be higher than 48kHz, often 44.1kHz)". How? 192kh locked and if it can be changed, then there's no obvious way to do it. Tried it with Windows system set it 44 and 48, same result. Everything is up to date.

      This is a major flaw in the web-audio-api on which audiotool is depending on.

      Surprisingly, the sample-rate cannot be changed. (link is only visible to registered users)

    Are there any ways to get your sample importing rights back?

      I think not. If you lost your rights due to a violation of AT's terms (you uploaded copyrighted material), it would be against their own interest to grant them to you again.
