## Abstract

A playback application is configured to analyze audio frames associated with transitions between segments within a media title to identify one or more portions of extraneous audio. The playback application is configured to analyze the one or more portions of extraneous audio and then determine which of the one or more corresponding audio frames should be dropped. In doing so, the playback application can analyze a topology associated with the media title to determine whether any specific portions of extraneous audio are to be played outside of a logical ordering of audio samples set forth in the topology. These specific portions of extraneous audio are preferentially removed.

## Claims

### Claim 1

A computer-implemented method for reducing playback of extraneous audio data, the method comprising:
identifying a first portion of extraneous audio data that is not related to either a first segment of video data or a second segment of video data that are played back sequentially when playing back a media title;
identifying a second portion of extraneous audio data that also is not related to either the first segment of video data or the second segment of video data;
determining that at least one of the first portion of extraneous audio data or the second portion of extraneous audio data conflicts with a topology corresponding to the media title; and
performing at least one operation that causes at least one of the first portion of extraneous audio data or the second portion of extraneous audio data to not be played back when playing back the first segment of video data and the second segment of video data.
