Abstract
Unwanted audio, such as explicit language, may be removed during audio playback. An audio player may identify and remove unwanted audio while playing an audio stream. Unwanted audio may be replaced with alternate audio, such as non-explicit lyrics, a “beep”, or silence. Metadata may be used to describe the location of unwanted audio within an audio stream to enable the removal or replacement of the unwanted audio with alternate audio. An audio player may switch between clean and explicit versions of a recording based on the locations described in the metadata. The metadata, as well as both the clean and explicit versions of the audio data, may be part of a single audio file, or the metadata may be separate from the audio data. Additionally, real-time recognition analysis may be used to identify unwanted audio during audio playback.
