21. Volume – the intensity of a soun d Tone – the audible characteristic of a sound. Pitch - is how high or low a sound is.

22. Principles of Sound Design

23. Mixing – the combination, balance , and control of multiple sound elements . Pace – time control, editing, order of events Stereo Imaging – Using left and right channels for depth. This refers to the aspect of sound recording and reproduction. Transition – how you get from one segment or element to another

24. Types of Transitions: Segue – one element stops, and the next begins (“cut” in the film) . Cross-fade – one element fades out, the next fades in, and they overlap on the way V-Fade – the first element fades to inaudible before the second element begins Waterfall – As the first element fades out, the second element begins at full volume. Better for voice transitions, than for effects

25. Accessibility: For individuals with visual impairments, audio media provides a means of accessing information and entertainment that might otherwise be difficult or impossible to obtain.. Convenience Audio media can be enjoyed on the go, making it a popular choice for people who are commuting or traveling. Emotional Impact Music and other types of audio media can have a powerful emotional impact on listeners, evoking a wide range of feelings and memories. Educational Value Audiobooks, podcasts, and other types of audio media can be a valuable source of information and education on a variety of topics. The Importance of Audio Media

26. ESTIMATED ANNOUNCE DATES Challenges in Audio Media Quality control: Ensuring that audio recordings are of high quality and free from errors or technical issues can be difficult. Copyright issues: Audio media is subject to copyright laws, which can make it difficult to use or distribute certain types of content. Language barriers: Audio media that is recorded in a particular language may be inaccessible to those who do not speak that language. AAI | Pro X
