ADJUSTING AUDIO AND NON-AUDIO FEATURES BASED ON NOISE METRICS AND SPEECH INTELLIGIBILITY METRICS
Some implementations involve determining a noise metric and/or a speech intelligibility metric and determining a compensation process corresponding to the noise metric and/or the speech intelligibility metric. The compensation process may involve altering a processing of audio data and/or applying a non-audio-based compensation method. In some examples, altering the processing of the audio data does not involve applying a broadband gain increase to the audio signals. Some examples involve applying the compensation process in an audio environment. Other examples involve determining compensation metadata corresponding to the compensation process and transmitting an encoded content stream that includes encoded compensation metadata, encoded video data and encoded audio data from a first device to one or more other devices.

Outside ordering system
An ordering system can be positioned partially, or completely, outside in a retail environment with an ordering device located outside of a building on a site. The ordering device receiving a first audio stream concurrently with a second audio stream from an employee and proceeds to capture the first audio stream with a first port of an on-site computing device while capturing the second audio stream with a second port of the on-site computing device. A customer strategy can be executed with an intelligence module of the on-site computing device connected to the ordering device with the on-site customer strategy directing automated interactions with a first on-site customer to compile a retail order. The employee may communicate directly with the intelligence module via the second port without interrupting the first audio stream.

Audio signal processing for noise reduction
A headphone, headphone system, and speech enhancing method is provided to enhance speech pick-up from the user of a headphone and includes receiving a plurality of signals from a set of microphones and generating a primary signal by array processing the microphone signals to steer a beam toward the user's mouth. A noise reference signal is also derived from one or more microphones via a delay-and-sum technique, and a voice estimate signal is generated by filtering the primary signal to remove components that are correlated to the noise reference signal.

Volume leveler controller and controlling method
Volume leveler controller and controlling method are disclosed. In one embodiment, A volume leveler controller includes an audio content classifier for identifying the content type of an audio signal in real time; and an adjusting unit for adjusting a volume leveler in a continuous manner based on the content type as identified. The adjusting unit may configured to positively correlate the dynamic gain of the volume leveler with informative content types of the audio signal, and negatively correlate the dynamic gain of the volume leveler with interfering content types of the audio signal.
