The bit Tune is an advanced measurement tool, and over the years it has evolved a few times, as we have added functions to it.         Some people who tried it years ago – often only to set up a bit Ten or bit One – haven’t ever seen the full feature set available to users today. Read on to learn what the bit Tune 3.1.0.1 SW can do for you.         ACOUSTIC REAL-TIME...

With this article we will understand why Audison Virtuoso 3.0 MPC (Mobile Phase Correction) technology is so important to achieve the highest listening quality in the car cabin. Sound waves have amplitude and phase characteristics. Amplitude is how powerful the wave is. The higher the pressure peaks, the louder the sound is perceived to be. Phase describes the timing of the wave – when the pressure peaks are occurring. Humans can often hear if the phase of the sound wave...

Dear Audison enthusiast, we wish to inform you that a major software and firmware upgrade for Audison bit One HD and bit One HD Virtuoso is available below: Virtuoso 3.0 web page The new release include the following features showing that even if you don’t have a bit Tune, the bit Virtuoso 3.0 gives the user advanced manual and automated tuning capabilities for both amplitude and phase:     – Built-in RTA with target curve support (display, creation, importing) and...

Audison_APM The development of Audison APM is the result of years of research and development into a complex topic, the evaluation of in-car sound quality. Many people in the industry have been talking about measuring acoustic performance without ever having achieved a tangible result up to now. The bit Tune hardware platform implements APM functionalities providing the market as well as industry specialists with a complete tool, enabling two innovative types of analysis which objectively evaluate customized and OEM car...

Audison bit Tune is the auto-calibration system for bit One HD Virtuoso for the setup of basic parameters (time alignment, equalization, levels, etc.), ensuring a correct acoustic result in a very short time. The bit Tune automatic routine also includes the diagnosis of common connection “errors” (channels/phase inversion, no signal from a channel/cable, etc.), to set the specialist free from his “routine” work and allow him to focus on the art of “fine-tuning” while listening.   Audison_bit_Tune   Thanks to...

The bit One HD Virtuoso is provided with advanced features for the integration with OEM infotainment and a purely audiophile vocation. The ability to independently configure the equalization for the MASTER and AUX inputs allows the user to create two separate systems without using different memory presets, the one dedicated to listening to the OEM Head Unit and the audiophile one to achieve maximum audio performance, in both cases preserving all the Head Unit functions (gong signal, alert, phone …)....

bit-One-HD-Virtuoso-RVA The bit One HD Virtuoso further improves its integration level with OEM Head Units with the RVA (Remote Volume Aux) function. This exclusive technology provides the ability to select an auxiliary source (I.e.: a HI-Res audio player or auxiliary wireless interface connected by digital inputs) and adjust its volume via the OEM Head Unit, offering full support to the management of the car priority signals such as parking sensor alerts, GPS messages, phone and vocal commands whilst music is...

In professional audio parametric equalizers have long since replaced the graphic ones for their greater precision of intervention as well as a considerable decrease in phase alterations. In fact, in graphic equalizers, to flatten a response curve, one is almost always forced to use almost all of the 31 intervention points offered, but each band introduces a phase shift that is added to the adjacent one, with the result of creating rotations on the whole spectrum. With a parametric equalizer,...

Virtuoso SW performs the spectrum analysis and flattens it by doing the magnitude DE-EQ automatically. Additionally, the new SW detect the electric polarity of each input channels and, in case of inverted polarities asks the user whether to correct them automatically or manually. The new SW also allows the correction of its phase domain response when the user enables the “Phase analysis” option flag. In this case, the presence of OEM All-pass filters will be detected and the algorithm’s routine...

The constant work of the Audison development team has produced the new software / firmware release v.2.0 in order to: 1. Strengthen the integration with the latest generation OEM systems and at the same time raise the performance level of Hi-End systems with a “purist” approach in Full DA HD configuration 2. Offer even more powerful signal processing tools to specialists including new types of filters 3. Make the use of PC-Software even more immediate through a renewed GUI that...

The use of these high rated components contributes to obtaining more musical medium-high frequencies and a powerful and fast low range when the analog outputs of the bit One HD Virtuoso are used. 1. SILMIC series ELNA capacitors specific for audio use, with cellulose dielectric treated with silk fiber to mitigate the mechanical energy that comes from the bit One HD vibrations, a common condition for in-car use. The result is a superior acoustic performance. 2. WIMA high performance Metallized...

    FIR filters therefore provide a better audio quality. So why are they used only by the bit One HD Virtuoso? Implementing a FIR filter requires the DSP chip to work with an enormous array of numbers and with much more complex calculations, and is therefore much more burdensome than the one of an IIR filter. As a result, the DSP Analog Device entry level chips of the “Sigma” family other audio processors are built with do not allow FIR...
