What is the tune special option?
=> The Tune Special option is in V7.8 and old versions, it is now replaced by the new Tune Audio Route option in V7.9 and new versions.
=> Setting the new option Tune Audio Route to "Group3" acts as setting the old Tune Special option to "Yes".
=> Boldbeast Recorder will change internal recording parameters according to your settings.
Does that mean Tune Audio Effect?
=> No.
=> Tune Audio Effect is a new option added in V8.0 and new versions. It can fix recording problems for some phones.
My Moto G 1st Gen works most of the time but periodically fails to record the other end. Bit of a pain as a reporter, I'm sure you can imagine.
=> You are using Android 4.4, is it right? If possible please upgrade to Android 5.0, it works very well.
=> If it's impossible for you to upgrade to Android 5.0, please root your phone, then you'll see the new "Change Audio Controls" option available in Boldbeast Recorder, enable it to record calls perfectly and reliably in both sides.
