PARAMETRIC JOINT-CODING OF AUDIO SOURCES

Thu, 23 Feb 2017 08:00:00 EST

The following coding scenario is addressed: A number of audio source signals need to be transmitted or stored for the purpose of mixing wave field synthesis, multi-channel surround, or stereo signals after decoding the source signals.

A multi-channel Class D audio amplifier is provided to substantially reduce channel-to-channel crosstalk by employing in each channel a local triangle ramp generator controlled by a single global digital timing signal. The noise critical timing/integrating capacitor for the triangle ramp generator resides locally in each channel and adjacent to the PWM comparator of that channel and referenced to the local ground of that channel. The amplifier can also include a duty cycle limitation circuit to limit output power availability depending on the impedance of any attached loads (speakers).

A network device communicates with one or another set of antennas depending on an orientation of the network device. The network device includes a first set of one or more antennas, a second set of one or more antennas, a processor, and memory having stored thereon instructions executable by the processor to cause the device to perform functions. The functions include (1) determining that an orientation of the network device is one of a first orientation and a second orientation; (2) if the determined orientation is the first orientation, then causing the network device to communicate using the first set of one or more antennas; and (3) if the determined the orientation is the second orientation, then causing the network device to communicate using the second set of one or more antennas.



ENVIRONMENT SENSING INTELLIGENT APPARATUS

An audio playback device may drive an audio reproduction device at a volume level. An audio capture device may convert sound waves into audio input. An environment sensing device may detect, based on the audio input, environmental conditions surrounding a user of the audio playback device, the environmental conditions including a loudness estimation indicative of a level of background noise included in the audio input and an audio content classification indicative of presence of speech in the audio input. The environment sensing device may also determine, according to the environmental conditions, a playback action to alter the volume level being provided by the audio playback device, and provide, to the audio playback device, an adjustment to the volume level in accordance with the playback action.
