AES70 Python Project Gathers Momentum. Expanding Control Options for Networked Audio and AV Systems

AES70py, a development project for an MIT licensed AES70 Library for Python programming, is making progress and receiving industry support. According to Matt Hardy (DeusO GmbH), the key point for the AES70 Python Project vision is to promote an IT convergence with network audio devices, meeting the pressing need for control systems within existing ecosystems: "AES70py offers a way to make this happen easily. It's also great for manufacturers doing things like automatic testing AES70 devices."

The first in a series of great value for speaker designers, this article provides an updated approach for the mathematical presentation of the various alignments, applicable to all computerized development tools. This is effectively an explanation of the code available in the Alignment Chart of the Speakerbench web application that Class Futtrup developed in collaboration with Jeff Candy.

Listen released SoundCheck 22. This update introduces many new features focusing on integration and flexibility for both production and R&D users. These include a new Python Integration module which enables SoundCheck to communicate with many devices and software programs using Python scripts, a new crest factor algorithm, a new multi-channel FFT analyzer, and additional post-processing tools. There are also significant upgrades to the statistics functionality, signal generator, metadata and more. SoundCheck 22 also operates on Apple Silicon processors with significant performance advantages.

Keysight Technologies has introduced the new PathWave Advanced Design System (ADS) 2023, an integrated design and simulation software that rapidly addresses increasing design complexity and higher frequencies in radio frequency (RF) and microwave applications. The updated design and simulation environment includes enhancements to electromagnetic (EM) simulation for circuit designers and streamlines integration of multi-technology circuit assembly and simulation into enterprise electronic design automation (EDA) design workflows.

Adding a great perspective on the topic of test and measurement, in particular for production lines, this article makes the case for using web interfaces, and embrace web standards for automated testing of audio equipment. The founder of QuantAsylum advocates an open-design philosophy for controlling and querying things via REST, which stands for Representational State Transfer, a widely accepted set of guidelines for creating reliable web APIs and leveraging the know-how of millions of developers.

FLAC is the most universal compression algorithm for audio, allowing to maintain a perfect reconstruction of the original data. As an audio manufacturer that supports FLAC in all its home audio (Wi-Fi) products, Sonos decided to improve its own development tools by creating an efficient alternative to using the original FLAC library (libFLAC) written in C, and created a Python implementation for lossless encoding/decoding focusing on real-time streams. pyFLAC is now available as a free-to-use package.

While Listen, Inc. continues to expand its series of videos about the latest SoundCheck 18 features and how to do audio test and measurement working from home, the Boston-based company also continues its series of online training classes. Designed to offer more chances for participants to gain advanced skills, the next online training class, about Advanced Sequence Writing, takes place Tuesday, July 14.

Listen announced the release of SoundCheck 16, its flagship audio measurement software. With a consistent schedule of product updates since the original launch in 1995, the new release of SoundCheck includes a bundle of new features that expand its capability and simplify ease of use. A completely re-designed THD+N analysis algorithm is now more accurate and significantly faster than other audio test systems, and is compliant with the AES17 stan­dard.
