saving microphone audio


Hello,

I wondered if there is any way to write out the audio from the microphone input. Some chap asked on the "Learn" page ( http://disq.us/p/1cc2pal ) corresponding to that control, but recieved no response. I am hard pressed to think of an instance where I would want to record audio & only use it in the app that did the recording. Is there something I am missing? Can we just save it anywhere, like a text record? I'm thinking "no".

 

There is documentation on how to get the audio into the PowerApp, but nothing to get the audio back out. Are we meant to run it all through Cortana before we can move the data elsewhere? If so, why not just have a STT input instead? I guess I could go old-school & dub it out if my headphone jack...

 

Cheers!

Hi D of A.V.L.ien,

 

I have seen an article about Microphone control in PowerApps, which says that we can use the SaveData function to save the recordings locally or the Patch function to update a data source. Hope this could be a reference for you:

Hi,

 

Just wondering has anyone been able to achieve Saving a microphone recording to a SharePoint list?

If so could someone quickly explain?


Thanks.

Hi 

 

I am getting something like this when I save an audio file from Andriod or iPhone to SharePoint List:

data/bb788abd-7848-449f-810b-2bd6368dcb19.aac

temp/recording_8BA1187E-158A-469E-9994-F644C6F619D8-1610-000001A0FBF5F1F0.caf

 

Does anyone know how I can make use of this to convert it to playable audio, maybe using C# .. ?

 

Thanks!

Sarah

Hi Sarah,

 

Unfortunately I haven't been able to save a recording to SharePoint list. Can you advise on how you achieved this?

I was only able to get it played back within the app.

 

Thanks.

Patch(SharePointListName, ForAll(Gallery1.AllItems,{Title: Title, VoiceMessage:Audio})); 

 

Could you at least maybe let me know WHERE PowerApps stores Mic Recordings? Is there a database or folder anywhere ?

 

Cheers, 

Sarah

any feedback please?

Hi Sarah,

 

Unfortunately I am unable to help you out. I don't know where the recordings are stored. I can only manage to get the recordings to playback within the app. That is as far as I have gone.

I am interested in this as well--but for CDS.

 

I know you can Collect() the audio from a mic into a temporary collection, but I don't know how it can be saved to an actual datasource. This might be something for an API to handle.

I have the same question.

First step was sending an e-mail with the Audio file. This results in a 64encoded attachment that contains the audio.

When I decode this using an online service it produces a .webm file.

I can play this in the VLC player which tells me that the code is: Opus Audio.

 

So I think my question would be: can someone confirm that the base64 encoded string is in fact Opus Audio encoded sound/audio ?
