Intelligently modifying the gain parameter of a playback device
First Claim
1. Tangible, non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors of a first playback device, cause the first playback device to perform functions comprising:
- entering a playback zone with a second playback device, wherein entering the playback zone comprises;
determining a first maximum sound pressure level (SPL) capability of the first playback device while in the playback zone based on (i) an output frequency characteristic of the first playback device, and (ii) an output frequency range characteristic of the second playback device; and
determining a first gain parameter for the first playback device while in the playback zone based on the first maximum SPL capability;
after entering the playback zone, receiving a first audio signal comprising a first audio frequency channel corresponding to the output frequency range of the second playback device and a second audio frequency channel different from the first audio frequency channel;
based on receiving the first audio signal (i) applying the first gain parameter to the second audio frequency channel of the first audio signal when playing the first audio frequency channel, and (ii) transmitting the first audio frequency channel of the first audio signal to the second playback device for playback by the second playback device in synchrony with playback of the first audio frequency channel by the first playback device;
leaving the playback zone such that the first playback device is no longer in the playback zone with the second playback device, wherein leaving the playback zone comprises;
determining a second maximum SPL capability of the first playback device based on the output frequency characteristic of the first playback device, wherein the second maximum SPL capability is lower than the first maximum SPL capability; and
determining a second gain parameter for the first playback device based on the second maximum SPL capability;
after leaving the playback zone, receiving a second audio signal; and
based on receiving the second audio signal, applying the second gain parameter to the second audio signal when playing the second audio signal.

Abstract
Techniques for optimizing a player based on the addition of a second player are disclosed. In an embodiment, when a first player no longer needs to play certain audio frequencies due to the addition of a second player, the gain of the first player is automatically increased as part of the setup process. In another embodiment, when a first player needs to play certain audio frequencies, for example due to the removal of a second player, the gain of the first player is automatically decreased. Many other embodiments are disclosed.
