Create voice recording in PowerApps

Now, let us see how to create voice recording in PowerApps. We will do this using a PowerApps Canvas app.

Step 1: Login to your PowerApps and create a canvas app using Mobile view.

Step 2: Next go to the Insert tab and drag and drop the below control inside your screen.

• Button —-Save
• TextBox —Enter File Name
• Label — Microphone in PowerApps
• Audio — Listen to your Recording
• Microphone —Record your Voice

Step 3: Next click on Audio control and update the Media property as Microphone1.Audio.

Step 4: Next click on Microphone and set the below property in OnStop

Set(tmpJson,JSON(Microphone1.Audio,IncludeBinaryData));
Set(strB64Audio, Mid(tmpJson,25,Len(tmpJson)-25));

As we know we can’t save the audio in SharePoint through PowerApps or Power Automate, here we have an option to convert our voice to a binary format and set it in a variable.

Step 5: Next click on Save button and go to onSelect property and update the below property like

SaveRecording.Run(strB64Audio,TextInput1.Text)

Here SaveRecording is your flow name which you will create to save your voice in SharePoint Online. So here you will get an error if you not yet created the flow. So update this property after step 6.

Step 6: Next go to the Power Automate and you can see I have already created my flow called SaveRecording. So you can also create a new flow and provide the name and the same name you have to provide in step 5.

Step 7: Here we need to add two steps. First, we have to initialize the variable then create a file to save our voice record.

Step 8: Next provide any name in the name section and type should be string and Value should be Initialize variable. Next Provide the SharePoint site address, File path and File Content to upload the Audio.

Step 9: In value section, you have to Ask in PowerApps to update the Value.

Step 10: Here in File Name you have to Ask in PowerApps and set the property Createfile-FileName.

Step 10: In file Content you have to go to expression and convert the variable to base64ToBinary and pass your variable here.

Step 11: Next go to the PowerApps and Run. Next start your recording and after some time stop the recording.

Next start your audio and it will start speaking whatever you recorded and next provide any file name in the textbox and click on Save button. So your recording file will save it in SharePoint library.

Step 12: So login to the SharePoint and go to your Audio library and see my recording file is successfully created over here.
