The primary goal of sound design in mixed reality is to create a realistic and immersive auditory experience that enhances the user's sense of presence in the virtual environment.

Convolution reverb is a technique used to simulate the natural reverberation of a space. It is not commonly used in sound design for mixed reality because it can be computationally expensive and can introduce latency.

HRTFs are used to simulate the way sound is perceived by the human ear. This allows sound designers to create a more realistic and immersive auditory experience for users of mixed reality headsets.

Headphone virtualization is a technique used to create a virtual surround sound experience using headphones. It is not a type of spatial audio used in mixed reality, as mixed reality headsets typically use built-in speakers or earbuds to deliver audio.

Binaural audio uses two channels to simulate the way sound is perceived by the human ear. Ambisonics, on the other hand, uses multiple channels to create a more immersive sound experience. Ambisonics can also be used to create binaural audio by rendering the Ambisonic signal to a binaural format.

Sound design plays a vital role in creating a sense of presence in mixed reality by creating a more realistic and immersive auditory experience, directing the user's attention, and creating a sense of emotional connection between the user and the virtual environment.

While sound designers working in mixed reality do need to create sound effects that are both realistic and engaging, this is not a unique challenge to mixed reality. Sound designers working in other fields, such as film and video games, also face this challenge.

Considering the user's physical environment when designing sound for mixed reality is important for creating a more realistic and immersive auditory experience, reducing unwanted noise, and improving the user's sense of spatial awareness.

Headphone virtualization software is not a common tool used by sound designers working in mixed reality, as mixed reality headsets typically use built-in speakers or earbuds to deliver audio.

Spatial audio is a more general term that encompasses all forms of audio that create a sense of space. 3D audio is a specific type of spatial audio that uses three-dimensional coordinates to position sounds in space. Spatial audio is typically used in mixed reality, while 3D audio is typically used in video games.

Translating real-world sounds into haptic feedback is not a common application of sound design in mixed reality. Haptic feedback is typically used to provide the user with a sense of touch or physical interaction, rather than auditory feedback.

Sound design can be used to create a sense of atmosphere and mood, convey emotions through the use of music and sound effects, and create a sense of empathy between the user and the virtual characters, all of which contribute to creating a sense of emotional connection between the user and the virtual environment in mixed reality.

Convolution reverb is not a common technique used to create a sense of realism in sound design for mixed reality because it can be computationally expensive and can introduce latency. Additionally, the natural reverberation of a space is often not present in mixed reality environments, as they are typically created using computer-generated imagery.

Considering the user's expectations when designing sound for mixed reality is important for creating a more immersive and engaging experience, reducing cognitive load, and creating a more consistent and cohesive experience across different mixed reality applications.
