Amplitude.getAnalyser() returning null

[feemcgill]

Issue description

getAnalyser() returns null unless

<div class="amplitude-wave-form"></div>
Or
<div class="amplitude-visualization"></div>
Are present on the page.

I had removed my waveform due to this IOS issue #389

And now my analyser is broke!

Environment

Chrome: https://whatsmybrowser.org/b/JS36SQH

• Amplitude.js Version: "5.0.2"

What is expected?

Would love to get the analyser on its own without waveform or AmplitudeJS registered visualization

Ah okay, AmplitudeJS only initializes the analyser if there is a use for it: https://github.com/521dimensions/amplitudejs/blob/master/src/fx/fx.js#L43. There were issues with the Web Audio API breaking other situations where devs weren't even using it, so I scoped it only if they needed it.

Let me run some tests to see if just initializing it without connecting to the source causes issues.

Hi @danpastori if someone is not working on it and its still requires some help can you assign this to me?

@ShlokJswl: Thanks for chiming in.

@danpastori's been busy writing our new book, so unfortunately that means AmplitudeJS won't get updates until later in 2023.

@jaydrogers Hello Jay, thanks for the info, is it still okay for me to work on this issue if it's not fixed?

I would suggest to start working on it only if @danpastori says so.

There are so many changes in Amplitude 6, I'd hate to have you go through the work and not have it get released.
