A managed directory service receives, from a computer system operated in a first network, a request to obtain a set of credentials usable to access resources in a second network. In response to the request, the managed directory service determines, based at least in part on a first set of permissions in a directory maintained in the second network, that the computer system is authorized to receive the set of credentials. The managed directory service provides the set of credentials to the computer system, which enables use of the set of credentials to identify a second set of permissions for accessing resources in the second network. |

Identity-aware application load balancer
Techniques for an identity-aware load balancer (ALB) are described. An identity-aware ALB can securely authenticate users when accessing web-based applications accessed through the ALB, or a node of the ALB. An application owner can configure an authentication action in the ALB. When a request for the application is received, the ALB inspects the request for a session cookie to determine whether the requesting user is logged-in. If the request includes a session cookie, the ALB can decrypt the session cookie and provide identity information with the request to the application. If no session cookie is included, or if the session cookie is expired, the ALB can authenticate the user with an identity provider specified in the authentication action. Integrating authentication into an ALB simplifies application development and maintenance, and improves security, since fewer changes to the application stack reduce the chances of errors being introduced. |

End point multiplexing for efficient layer 4 switching
This disclosure provides for an enhancement to a transport layer switch and, in particular the management of end points. In this approach, a memory space, such as a large logical ring buffer, is shared by incumbent connections to facilitate a space multiplexing end point management scheme. Preferably, memory allocation in the memory space is done packet-by-packet dynamically. Because the memory space is shared by all admitted connections, packets belonging to the same connection are not necessarily located physically consecutive to each other. A packet indexing mechanism that implements a set of pointers ensures that consecutiveness for packets on the same connection is maintained. This approach to end point multiplexing provides significant benefits by improving resource utilization, and enabling a higher number of connections to be served. |

A downscaled version of an audio decoding procedure may more effectively and/or at improved compliance maintenance be achieved if the synthesis window used for downscaled audio decoding is a downsampled version of a reference synthesis window involved in the non-downscaled audio decoding procedure by downsampling by the downsampling factor by which the downsampled sampling rate and the original sampling rate deviate, and downsampled using a segmental interpolation in segments of ¼ of the frame length. |

Encoding apparatus and decoding apparatus for transforming between modified discrete cosine transform-based coder and different coder
An encoding apparatus and a decoding apparatus in a transform between a Modified Discrete Cosine Transform (MDCT)-based coder and a different coder are provided. The encoding apparatus may encode additional information to restore an input signal encoded according to the MDCT-based coding scheme, when switching occurs between the MDCT-based coder and the different coder. Accordingly, an unnecessary bitstream may be prevented from being generated, and minimum additional information may be encoded. |

Systems and methods for processing an audio signal for replay on an audio device
Systems and methods for processing an audio signal are provided for replay on an audio device. An audio signal is spectrally decomposed into a plurality of subband signals using band pass filters. Each of the subband signals are provided to a respective modulator and subsequently, from the modulator output, provided to a respective first processing path that includes a first dynamic range compressor, DRC. Each subband signal is feedforward compressed by the respective first DRC to obtain a feedforward-compressed subband signal, wherein the first DRC is slowed relative to an instantaneous DRC. Subsequently, each feedforward-compressed subband signal is provided to a second processing path that includes a second DRC, wherein the feedforward-compressed subband signal is compressed by the respective second DRC and outputted to the respective modulator. Modulation of the subband signals is then performed in dependence on the output of the second processing path. Finally, the feedforward-compressed subband signals are recombined. |

Time-domain stereo encoding and decoding method and related product
An audio encoding and decoding method and a related apparatus are provided. The audio encoding method may include: determining a coding mode of a current frame; when determining that the coding mode of the current frame is an anticorrelated signal coding mode, performing time-domain downmix processing on left and right channel signals in the current frame by using a time-domain downmix processing manner corresponding to the anticorrelated signal coding mode, to obtain a primary channel signal and a secondary channel signal, where the time-domain downmix processing manner corresponding to the anticorrelated signal coding mode is a time-domain downmix processing manner corresponding to an anticorrelated signal channel combination scheme, and the anticorrelated signal channel combination scheme is a channel combination scheme corresponding to a near out of phase signal; and encoding the obtained primary channel signal and secondary channel signal in the current frame. |

Spatially formatted enhanced audio data for backward compatible audio bitstreams
In general, techniques are described by which to specify spatially formatted enhanced audio data for backward compatible audio bitstreams. A device comprising a memory and one or more processors may be configured to perform the techniques. The memory may store the backward compatible bitstream that conforms to a legacy transport format. The processor(s) may obtain, from the backward compatible bitstream, legacy audio data that conforms to a legacy audio format and a spatially formatted extended audio stream. The processor(s) may process the spatially formatted extended audio stream to obtain extended audio data that enhances the legacy audio data. The processor(s) may next obtain, based on the legacy audio data and the extended audio data, enhanced audio data that conforms to an enhanced audio format. The processor(s) may output the enhanced audio data to one or more speakers. |

Seamless text dependent enrollment
Methods and systems for transforming a text-independent enrollment of a customer in a self-service system into a text-dependent enrollment are provided. A request for authentication of a customer that is enrolled in the self-service system with a text-independent voice print is received. A request is transmitted to the customer to repeat a passphrase and the customer's response is received as an audio stream of the passphrase. The customer is authenticated by comparing the audio stream of the passphrase against the text-independent voice print and if the customer is authenticated then a text-dependent voice print is created based on the passphrase, otherwise discard the audio stream of the passphrase. |

Providing pre-computed hotword models
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for obtaining, for each of multiple words or sub-words, audio data corresponding to multiple users speaking the word or sub-word; training, for each of the multiple words or sub-words, a pre-computed hotword model for the word or sub-word based on the audio data for the word or sub-word; receiving a candidate hotword from a computing device; identifying one or more pre-computed hotword models that correspond to the candidate hotword; and providing the identified, pre-computed hotword models to the computing device. |
