audio dropouts with mobile browsers #77

Hi, first of all thank you for this great tool, really impressing!!

Unfortunately I am experiencing little dropouts (glitches) when listening to music with FFT analysis on my mobile phone (Samsung S22, newest Android version) on browsers like Chrome and even worse on Firefox. Do you have any experience with this?

One interesting thing: The glitches continue, even if I switch off the FFT analysis via toggleAnalyzer(). So it seems to be a problem with the audio node, not with the FFT analysis or the canvas.

Without the Analyser plugin, the music plays smoothly.

Thank you for your help, Holger

I am experiencing a similar issue. Audio playback stutters (pops, glitches). I assume it is latency drops/buffering issues (it sounds like it), but without any performance throttling. Sometimes the audio playback speeds up for a couple of seconds and slows down again.

Format is mp3/mpeg, and have tested on ipados and ios in chrome and safari. It does not happen in any way if the audiomotion visualizer is not instantiated. If on desktop both the audio playback is smooth and without any errors (including an audiomotion viszualizer running).

Have tested loRes and other settings that might reduce the load but nothing works.

Is there any workarounds I might be missing?

Thank you, Jakob,

that describes exactly the problem I have. I don't use the analyzer as soon as a mobile device is detected. Which is a bit sad of course ...

Best, Holger
