The next generation of low frequency (LF) audio technology is now in production.
At a conference this week, the U.S. Department of Energy’s (DOE) Office of Science announced the development of the first commercially available low frequency waveguide for high frequency (HF) applications.
The waveguide will help with the creation of high quality audio recordings, which will allow for the development and commercialization of low-cost, high-fidelity audio products.
“A new low-frequency waveguide has been developed that can be used to produce low-fiber, low-noise audio for use in applications such as medical imaging, video surveillance, navigation, and industrial monitoring,” said David Houghton, the senior associate administrator for Advanced Research Projects Agency-Energy (ARPA-E).
“This is a very exciting development that will bring low-power, low cost, high fidelity audio production to the forefront of the high-frequency audio market.”
Low-fibre high-res sound is used for the high quality of voice over internet protocols and other applications that rely on high-quality audio.
HF audio can be produced with a high frequency wave, which can be heard through walls, or with a narrowband low frequency, which is much quieter.
These two frequencies can be tuned to create a wide range of frequencies.
The U.K.-based AudioWorks has developed an inexpensive low-loss, low noise (LOL) waveguide to make the creation and application of LF audio possible.
The new waveguide is manufactured by AudioWorks, a U.UK company based in the United Kingdom, and is being made in a laboratory in Scotland.
The low-quality, low frequency acoustic waveguide provides the sonic characteristics of an analog high-end analog signal, which provides high fidelity recording of the digital sound from a digital source.
A low-resolution high-pass filter is used to create the audio signal, while a narrow-band low-pass bandpass filter attenuates the high frequency components of the signal.
These low-res, low energy components of a high-definition signal are not normally heard through the human ear, but can be very important when recording audio.
“By having the low-energy components attenuated, it allows for better fidelity and the ability to capture the audio signals and audio signals in the most realistic way possible,” said James Gulledge, a research scientist in the Department of Physics at the University of Exeter, UK.
“This can make the recordings sound much more natural, even when the digital signal is too low for the human hearing system to detect.”
This new waveguides development, which was recently published in the journal Advanced Materials, is designed to be more efficient and quieter than current low- and high-gain audio devices.
The technology can also produce a very quiet signal with a low energy footprint, which has important applications in medical imaging and other medical applications.
A key goal of this research is to produce a low-price, high performance, high quality low-gain, low bandwidth, high energy, high frequency audio source for low-end audio applications.
In addition to this, the research team plans to further develop the technology, and the company plans to use it in the production of new high-performance, low volume, high cost audio systems.
The researchers expect the technology will have applications in several areas of audio, including digital imaging, medical imaging for medical monitoring, industrial monitoring, and commercial applications.
