RINGR always records your audio in a separate track per participant and at the highest quality. After the call is over we apply our sync and post processing algorithms and can produce a variety of mixdowns and formats for your call - you do not need to select the formats before your call. RINGR Basic users only get access to our standard MP3 mono mixdown, however, RINGR premium subscribers (and free trial users) can simply add a format to their call any time after its recorded and download it within seconds.
To add a format, click on your conversation in the call list of the RINGR account site https://account.ringr.com/#conversation and then hit the 'add format' button:
Which will pop open the add format dialog where you can pick a preset or use our custom settings to create the version you need.
If you'd like RINGR to produce this file type for every call, simply use the checkbox at the bottom to make ti the default (this setting can also be adjusted in your account under audio settings).
Finally, if you need help figuring out what file type to download, we have some advice at: https://ringrhelp.zendesk.com/hc/en-us/articles/225996568
