Dolby Digital Plus is an advanced surround sound audio codec that delivers high-quality sound for online streaming, broadcast, and downloaded content.

Dolby Pro Logic IIz is a technology that expands the soundstage of your entertainment by adding two additional channels of sound above the front left and right speakers. This creates a more immersive and realistic sound field that enhances the depth and dimension of your audio. Dolby Pro Logic IIz works with any stereo or multichannel source and can be enabled or disabled according to your preference[^1^].

Dolby Audio Optimization is a technology that optimizes the audio performance of your PC by compensating for the limitations of its hardware. Dolby Audio Optimization applies various processing techniques such as frequency response correction, volume maximization, dynamic range control, and speaker protection to ensure that you get the best possible sound quality from your PC’s built-in speakers or headphones[^1^].

Dolby Audio Profile is a feature that allows you to customize your PC’s audio settings according to your preferences and listening environment. You can choose from four preset profiles: Movie, Music, Game, and Voice, or create your own profile using the ten-band graphic equalizer.
