First Aid Instructions if Glitchy Playback in the Studio

André Michelle

Since the Studio isn't running inside a Flash plugin anymore, we are facing many more dependencies that can potentially lower the experience in terms of performance. To rule out common issues, here is a list of things to check before getting too frustrated:

First Things First

  • Install the latest stable version of Chrome. You can check your current version by typing chrome://settings/help into the address bar.
  • Close any browser tabs you don't need.
  • Run the Studio in incognito mode to prevent extensions from creating possible interferences.
  • Quit background software like Skype, WhatsApp, Dropbox, Slack, etc.
  • Check for CPU intensive, unnecessary processes in your Task Manager (Windows) or Activity Monitor (Mac).
  • Free up space on your hard disk if your machine is running out of it.
  • Reduce your browser's window if you have a very high screen resolution.
  • Try the Support >> Help >> Audiotool Booster
  • Support >> Help >> WebGL pitfalls and how to fix them

The Way You Build Your Track

Arrangements can often contain inefficient effect chains where a bunch of devices could just be removed or merged without altering the final sound. Ideally you should not bother, but every device on the desktop takes valuable CPU time. Here are some tips:

  • Combinations of Stereo-Detune and Stereo-Enhancer can often be merged into one.
  • Compressors can make you believe that the sound is more powerful. Try bypassing them to see if they are really necessary. Sometimes just increasing the volume achieves the same effect.
  • The Heisenberg can be very CPU intensive. Try to minimise their amount in your arrangement or, if you don't need any Heisenberg specific feature, use the less CPU intensive Pulverisateur to create your sound.
  • Quantum as a multi-band compressor is mainly used for mastering and to alter the dynamic of specific frequency bands in complex sounds. If you do not need these features, replace it with Gravity, which needs way less CPU.
  • When using Curve, switch off the filters you don't need.
  • Switch off the spectrum analyser in Quantum and Curve once you've adjusted their settings.
  • If a particular effect or chain of effects is used by several sounds, connect it to a mixer as a send/return effects chain instead of duplicating and inserting it after each sound.
  • Make your arrangement compact. Long cables need more pixels to be drawn.
  • When working on parts of a big arrangement, deactivate any timeline tracks that you don't need to hear.

    Great explanation of the basics of digital audio routing and processing and the relationship between sample rate, buffer size, latency, DSP load, CPU load and how glitchy playback (buffer under-run) happens.

    I originally set up my account by signing into a Google account. I see that I can change my email/password and would like to do that. Unfortunately, the app/site doesn't recognize my Google account password as my current password. When I try to reset the password it doesn't work. It says "We're sorry! Your account was found, but the password reset mail could not be sent. Please contact the staff. Details: (details not available)". How do I reset it plz help before I lose my progress. Can someone in the staff just reset my password and tell me it please!

    Plz help. I have done everything you said and it is still really glitchy. I can't use the booster because i have a chrome book and it seems that it doesn't work on my particular computer. I have activated the hardware acceleration and that doesn't seem to make a difference. I am giving up hope...

    Heads Up!

    The latest Chrome 79.0.3945.79 (Mac) reintroduces new glitches while playback. An issue has been filed for the developer to fix.

      Confirmed on Linux as well, but it's just a subtle difference for me.

    There is a new experimental flag introduced by the Chrome developers to test a different internal audio-infrastructure for the web-audio-api.

    Please visit: chrome://flags/#audio-worklet-realtime-thread and enable it. If you discover any changes (good or bad) with audiotool, please reply to this comment. Thanks.

      For me it doesn't make any obvious difference. I get the same frequency of overruns in a specific draft with or without.

    Remember when we thought Next was gonna run so much smoother than flash haha

      Above tips were actually valid for the Flash app as well.

      We tested the Flash app against Next before launch and Next was indeed performing equally if not better than Flash. However, it looks like Next performance differs extremely on different systems. Anyway, we are permanently improving the performance of the studio, so if you can contribute some data about your system in a new topic, we can get to the bottom of this. Also please read WebGL pitfalls and how to fix them (This helped a lot of users with poor performance on decent systems)

    The audio freezes a lot and has a staticy noise. I've made sure I do not have any other tabs open or things like that. Please.

    Sometimes, playing a big arrangement with the timeline view expanded will help reduce glitchiness.

      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.
