Dialogue Track

对白轨 (Dialogue Track) is a standalone audio track consisting primarily of character dialogue, monologues, narration, radio clips, or other spoken content. It is commonly found in film soundtracks, radio dramas, concept albums, comedy albums, and live concert recordings, and is used to preserve the plot, context, or on-stage interactions.

Dialogue may be taken directly from the finished film or television production, or it may be re-edited or re-recorded for the recording. If film dialogue is used, the track may retain ambient sound, sound effects, and background music; therefore, “dialogue” describes the primary content rather than just clean vocals in the audio channel. Different releases may also replace segments due to rights or censorship. A standalone “Dialogue Track” must be distinguished from spoken word within a song. Rap, spoken word, and dialogue can be integral parts of a musical work; they constitute a separate track only when a master or digital tracklist designates them as independent playback units. Databases may also label “dialogue segments” within a single long track, but these are at a different hierarchical level.

对白轨 typically still has a title, duration, and track number, but does not necessarily correspond to a standalone musical work or ISRC assignment practices. Performer credits may include actor, narrator, speaker, and voice artist; lyricists, screenwriters, and sampled sources should also be distinguished based on release information.

In multichannel DVDs, “dialogue channel” typically refers to the center channel in the mix that primarily carries dialogue; it is not the same as a “Dialogue Track.” The former refers to channel layout and the result of the mix, while the latter refers to track structure.
