We actually don't support exporting audio files, so it's not something you can normally do from Trint.
However, there is a way -- it's just a tad complicated ...
You can save the recording by doing the following:
Sign into your Trint account on a computer
Open up the Trint
Export it into an interactive transcript. This will download a ZIP folder to your device, which will have an HTML file within it.
Once opened on your browser, this HTML file will have a rudimentary version of your Trint, with the audio bar at the very top. You can right-click the audio and select Save to save it to your device.
Let us know if you have any questions by emailing firstname.lastname@example.org.
