A time warp contour calculator for use in an audio signal decoder receives an encoded warp ratio information, derives a sequence of warp ratio values from the encoded warp ratio information, and obtains warp contour node values starting from a time warp contour start value. Ratios between the time warp contour node values and the time warp contour starting value are determined by the warp ratio values. The time warp contour calculator computes a time warp contour node value of a given time warp contour node, on the basis of a product-formation having a ratio between the time warp contour node values of the intermediate time warp contour node and the time warp contour starting value and a ratio between the time warp contour node values of the given time warp contour node and of the intermediate time warp contour node as factors.

A multi-participant conference system and method is described. The multi-participant system includes a PSTN client, at least one remote client and a first participant client. The PSTN client communicates audio data and the remote clients communicate audio-video data. The first participant client includes a voice over IP (VoIP) encoder, a VoIP decoder, a first audio mixer, and a second audio mixer. The VoIP encoder compresses audio data transported to the PSTN client. The VoIP decoder then decodes audio data from the PSTN client. The first audio mixer mixes the decoded audio data from the PSTN client with the audio-video data from the first participant into a first mixed audio-video data stream transmitted to the remote client. The second audio mixer mixes the audio-video data stream from the first participant with the audio-video data stream from each remote client into a second mixed audio transmitted to the PSTN client.

Audio signals are processed for use in a communication event. A data store may be queried to obtain an indication of an echo direction, which relates to a direction from which audio signals output from the audio output are likely to be received at a microphone array (plurality of microphones) of a device. Beamformer coefficients of an adaptive beamformer of the device are determined in dependence upon the received indication of the echo direction. Audio signals are received at the microphone array. The adaptive beamformer applies the determined beamformer coefficients to the received audio signals, thereby generating a beamformer output for use in the communication event. The beamformer coefficients are determined such that echo suppression is applied to audio signals received at the microphone array from the indicated echo direction.

A content server generates sponsored audio including procedurally generated background music. The content server obtains reference music features describing musicological characteristics of reference songs as well as sponsored audio information received from a third-party. The content server determines music generation parameters based on the sponsored audio information and based on a music model mapping the reference music features to music generation parameters. The music model may incorporate machine learning techniques to improve the mapping. The content server generates background music by using the determined music generation parameters as input to a procedural music algorithm, and generates sponsored audio by combining the generated background music concurrently with an audio voiceover obtained from the sponsored audio information. The sponsored audio is provided to a client device, which presents the sponsored audio to a user.

A delay time counter in a DSP cyclically counts a sampling clock from zero to a delay time sampling count and issues a delay time interrupt to a CPU each time the sampling clock count reaches the delay time sampling count. The CPU measures a time difference between each time the DSP issues the delay time interrupt and each time sequence clock interrupts occur a number of times corresponding to the delay time. Then, in order to reduce this time difference, the CPU increases or decreases a maximum count that is set to the sequence clock counter. Therefore, in the next delay process, the shift between the time by which the automatic performance is advanced by the CPU (which is equal to the delay time) and the timing of the delay process executed by the DSP (which is also equal in length to the delay time) will be corrected.

Earlier this year Apple came under some criticism after a report by the Guardian on how Apple hired contractors to listen to a small percentage of anonymized ‌Siri‌ recordings to evaluate the responses with the purpose of improving accuracy and reliability.

In response, Apple promised that it would introduce options in a forthcoming update that would allow users to opt out of sharing their audio recordings.

Those options arrived with the releases of iOS 13.2, iPadOS 13.2, and macOS 10.15.1.

In this podcast, Tyler walks us through how to access and change these new options.
