Email services and messaging apps have their own limits for file size to send. So the best way to send larger recordings is by uploading them to the cloud service of your choice and sharing just a private link. To do so:
Install and set up a cloud service app, like Google Drive or Dropbox
In Audio Recorder Lite app select Share from recordings' context menu
Choose cloud service app from the list and follow the upload instructions (Tip: make sure you're connected to the WiFi network)
After uploading is complete share a private link using an email or messaging app.
