In Sonar each audio stream is processed independently from the others. In the mixer tab you can assign a different audio device (like a headset, speakers, microphone...) to each audio stream (Game, Chat, Microphone) and tune finely its volume. Furthermore, you will also have a master volume that will rule them all!
That means that you can finally tune as much as you want the game sound without impacting your teammate voice.
What is an Equalizer?
An EQ is a tool that lets you adjust and control the sound to improve what you hear while playing. It allows you to hear more or less of the sound from a specific frequency range. When we talk about ‘Highs’ and ‘Lows’ of sound, we are talking about sound frequencies. In simple terms, adjusting each frequency lets you hear more of what you want and less of what you don’t.
