What's new in Action! 4.18.1?
To allow easier use of OriSound function (recording original audio directly from games and applications) a new Auto mode has been added. In this mode (with Game Mode and Selected Application as primary audio device) Action! will automatically switch audio source to selected/active game.
Fixed AVerMedia GC573 4K HDR capture card sound support
Added volume meter for primary and secondary (microphone) devices displayed on UI
Added live sound playback (via PC speakers/headphones) of audio from capturing devices

What's new in Action! 4.17.1?
HOTFIX: Fixed mono microphone recording

What's new in Action! 4.17.0?
NEW FEATURE: OriSound - long-awaited feature that allows to record audio exclusively
from selected game or application! Don't waste money on additional PC or specialized headphones!
Now you can select your favorite voice chat application (like Discord) and record it into separate
audio track that will not be mixed with main audio track!
Additionally the sound you record will never be modified by sound card post-processing so
you always get the original volume, pitch and tone.
It will also not get disturbed by random system "blips" comming from popup windows etc.

HOW TO USE ORISOUND:

1. Use "Selected application" from audio device list (either primary, secondary or aux device).
2. A window will appear showing currently detected sound sources in the system
(from system audio mixer)
3. If the application you want record sound from is not running or is not visible on the list you
can use the '+' button to select its exe file (you need to manually find its location first)

NOTES: This feature might not work for anti-cheat protected games and some games with
spatial audio like Dolby Atmos. This will be improved soon in version 4.18.0.
