xCORE-Audio sound processors

30.03.2015

XMOS recently announced the start of deliveries of not only 16-core XMOS xCORE-200 microcontrollers with Gigabit Ethernet support, designed for IoT devices, but also sound processors of the xCORE-Audio family.

According to the manufacturer, these processors are designed to meet the requirements of both consumer devices and equipment designed for professionals. The family includes two branches. xCORE-Audio Hi-Res processors are more suitable for consumer stereo and multi-channel devices, while xCORE-Audio Live processors are more suitable for high-end consumer devices and professional equipment, including mixing consoles.

xCORE-Audio processors support PCM and DSD, sampling rates 44,1, 48, 88,2, 96, 176,4, 192 and 352,8 and 384 kHz (the manufacturer promises to add support for 768 kHz soon), 16-, 24 - and 32-bit data representation. The common features of representatives of both lines include the presence of USB and SPDIF inputs, I2S, SPDIF, DSD / DoP outputs, as well as an analog output.

Representatives of the Hi-Res line will be produced with the number of channels 2, 2.1, 5.1, 7.1. Trial samples of the Hi-Res 2 stereo processor are still available. The cost of its serial copies will not exceed $2. An evaluation board is already available for this processor.

The first representatives of the Live line should appear in April. These processors will be available in 4, 8 and 16 channel variants. In addition to the inputs and outputs listed above, they have an ADAT input, ADAT and MIDI outputs.

For the external design of the xCORE-Audio sound processors, TQFP-type cases were chosen. The OS compatible list includes Android, Windows and Mac OS X.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

round salt 15.11.2006

Often we are annoyed by salt sticking together in a salt shaker and not wanting to pour in any way.

Indian crystallographers from the Central Institute for Research on Salt and Marine Chemicals in the city of Bhavnagar believe that the matter is in the cubic form of salt crystals. They are in close contact with their flat edges and stick together under the influence of air moisture.

Scientists have suggested adding small amounts of the amino acid glycine to the brine from which table salt is boiled. Then the salt crystals are rounded, acquiring the shape of dodecahedrons. Such salt sticks together less and flows better.
