I've put together a survey that uses the audio function, but the button that displays in the field app does not appear when accessing the survey through the web app. I am guessing that the web app just does not support this function, but wanted to check...
You're correct, it's not possible to record audio into an audio question in the Survey123 web app. It does allow you to upload an existing audio file though (as your screenshot demonstrates). Please see a list of differences in question types between the field and web apps here: Quick reference—Survey123 for ArcGIS | Documentation.
If this functionality is important for your surveys you could raise an enhancement request with Esri Support. This helps us assess demand for certain features and prioritise accordingly.
Thanks for your quick response! I will be sure to log this as an enhancement request.
Before I spent time trying to figure it out, do you know if it will be possible to embed an audio recorder plugin, like recorder.js, into my survey so that I can have an audio recorder button on the web app?
