Audio post production usually refers to the post-production of audio that is synchronized with video. This applies to TV, cinema, and commercials. One major aspect of audio post production is the use of ADR, or automatic dialogue replacement. Sometimes the original, or production audio, lacks in performance or quality, and the actor or actors are brought into a sound studio to record some or all of their dialogue from the project. Other elements such as foley, music, and voiceover, are also added during post production.

The term contemporary art gallery refers usually to a privately owned for-profit commercial gallery. These galleries are often found clustered together in large urban centers. Smaller cities are usually home to at least one gallery, but they may also be found in towns or villages, and remote areas where artists congregate, e.g. the Taos art colony and St Ives, Cornwall.

Contemporary art galleries are usually open to the general public without charge; however, some are semi-private. They usually profit by taking a portion of art sales; from 25% to 50% is typical. There are also many non-profit or collective galleries. Some galleries in cities like Tokyo charge the artists a flat rate per day, though this is considered distasteful in some international art markets. Galleries often hang solo shows. Curators often create group shows that say something about a certain theme, trend in art, or group of associated artists. Galleries sometimes choose to represent artists exclusively, giving them the opportunity to show regularly.

A gallery’s definition can also include the artist cooperative or artist-run space, which often (in North America and Western Europe) operates as a space with a more democratic mission and selection process. Such galleries typically have a board of directors and a volunteer or paid support staff that select and curate shows by committee, or some kind of similar process to choose art that typically lacks commercial ends.
