Abstract: Techniques are disclosed for providing a virtual demonstration experience that includes presenting a user interface including an option to select between at least two configurations. The techniques also include initiating a first playback of an audio track for a first configuration, the first playback based on a binaural recording of a first audio system setup rendering the audio track. The techniques also include, in response to selection of a second configuration while the first playback of the audio track is occurring, switching to a second playback of the audio track, the second playback based on a binaural recording of a second audio system setup rendering the audio track, the second audio system setup different from the first audio system setup, wherein switching to the second playback of the audio track continues from where the first playback was prior to switching to the second playback.

Abstract: Architectures and techniques to visually indicate an operational state of an electronic device. In some instances, the electronic device comprises a voice-controlled device configured to interact with a user through voice input and visual output. The voice-controlled device may be positioned in a home environment, such as on a table in a room of the environment. The user may interact with the voice-controlled device through speech and the voice-controlled device may perform operations requested by the speech. As the voice-controlled device enters different operational states while interacting with the user, one or more lights of the voice-controlled device may be illuminated to indicate the different operational states.
