Re: saving microphone audio

I've setup my flow as described and It's sending audio emails successfully, however, the format sent is in the generic file (.) format and not a recognized audio format.  Any suggestions?

You can try to name the audio file as AudioFileName.mp4

Re: saving microphone audio

it won't work. Despite the documentation the audio output file format is not known.

Hello Darius,

Did you try to add .mp4 at the end of the file name? 
And it's not working? Strange. It works for me

Re: saving microphone audio

Had some fun playing with this tonight and was successful using Azure Blob Storage and following along with Evan Chaki's blog post here.

The gist:

- Create an Azure Blob Container

- Add the Azure Blob Storage data source to your powerapp

- OnStop of your recorder Control:

// First collection to show the raw appres url from mic.audio
Collect(
    colLocalSounds,
    {
        ID: CountRows(colLocalSounds) + 1,
        sounds: Microphone1.Audio
    }
);

// Second collection to visualize the blob metadata once saved
ClearCollect(
    colAzureBlob,
   AzureBlobStorage.CreateFile("NAME_OF_YOUR_BLOB_CONTAINER","test_audio" & Text(Now(),LongDateTime24) & ".wav", Microphone1.Audio)
);

// Third collection to get the actual audio
ClearCollect(
    colAzureAudio,
    AzureBlobStorage.GetFileContent(First(colAzureBlob.Id).Id)
)

- You can pare these down as you see fit. Good for visualizations at first.

- In Azure Portal, you can quickly "Generate SAS and URL" to play the audio in the browser

Good luck!
