Calrec Audio today announced a free, comprehensive program of online training videos on Summa, its newest audio console.
Before we talk about putting these new 3D sound systems into a room, let's talk about the differences between Dolby Atmos and Auro-3D. They are significant.
With systems available that deliver audio quality better than the CD standard, no longer will there be compromises when wireless options are looked into. And by having a system completely agnostic to the source and the speaker, installers can now offer the same level of performance when adding to an already existing system that allows a profitable job for them and a level of quality the client demands.
Being a big Sonos fan (I have 6 zones in my house), I've always been curious if I'd see any improvement with an external DAC. Recently I had the opportunity to test a Rialto 400 from AudioControl with my Sonos system and was impressed.
Mastering wireless audio can bring many benefits, but doing so demands understanding of both the solution's inherent advantages, and its challenges.
WiSA-certified speakers operate in a frequency spectrum that is much different than that of Bluetooth or WiFi. These products operate between 5.2Ghz and 5.7Ghz in a zone known as Dynamic Frequency Selection or DFS.
"The single biggest problem in communication is the illusion that it has taken place." - George Bernard Shaw (1856-1950), Irish playwright
Only four parameters are needed to define everything that affects audio fidelity: Frequency response, distortion, noise, and time-based errors.
Starting with Dolby Surround, which used four channels (front left, front right, phantom center, mono surround - though usually using two speakers), the public began to expect the increased realism brought about by sound location cues being able to move across the front soundstage, and from front to rear for ambience or special effects.
Feedback is very large subject, and I am going to limit myself to some simple tutorial comments and a discussion of phenomena associated with complexity in distortion created by nonlinear gain stages, negative feedback, and the audio signal. Taken singly, these phenomena seem simple enough, but when they interact, they create distortions out of proportion to what you expect from the specifications found in product brochures. There are linear and non-linear forms of distortion. Linear distortions affect the amplitude and phase of audio signals, but don't show up on harmonic distortion analyzers as added frequency components that weren't there in the first place. Tone controls are a good example of circuits with linear distortion. Nonlinear distortions are those which add new frequency components to the original signal, either as harmonic multiples of the original frequencies or as sidebands resulting from their non-linear interaction between the original frequencies. Nonlinearities are often deliberately created in musical instruments themselves, but they are unwanted in music reproduction. We will be talking about nonlinear distortions.
Regardless of the fact that you spent a minor (or major) fortune on your home stereo or theater system, it still is possible that a breakdown can happen. Since loudspeakers always manifest the problem regardless of where it actually occurs, many are quick to blame them. Sometimes folks are right - the loudspeaker failed. But often there is a failure elsewhere in the system that is merely being passed on to the speakers.
Introducing iAMÂ© - bringing sophisticated, yet affordable, touchpanel control to your iTunesÂ© library. iAMÂ© enables you to enjoy your media for a whole-house experience, without the need of expensive media servers, iPodsÂ© and associated docks, or lugging your PC around with you.
Yet another advanced compact disc recording format which made a valiant attempt at deposing both conventionally recorded compact discs as well as Sony's SACDs was the format, xrcd. Although SACD seems to have a slight edge on xrcd, this relatively obscure format continues to sell.
Many users are digitizing music, using mobile wireless devices but still getting playlist fatitue. Others are using the Internet to tap the digitized libraries of many sources. These streaming audio sources are expanding rapidly and many are commercial-free and subscription-free. With the new audio sources and software such as SelectRadio, you too can find the cure to playlist fatique!
If you agree that a Ferrari requires high-octane fuel and that your home system needs high definition music, then you may also agree that your toys too have evolved again. You may also find your children listening to your music.
