How to Use RTA
Here is the RTA main screen:
Band Size
To use RTA, select the band size that you want, either Octave or 1/3 Octave.
Canzoni napoletana spartiti pianoforte pdf. Decay Modes and Speed
Select the decay mode and speed. You can select one of the exponential decay modes, which are labelled in seconds. The seconds indicate the amount of time for a bar to decay by 20dB.
Also, you can select Peak Hold, which holds the highest value that a bar has reached. To reset Peak Hold, re-select Peak Hold mode.
There is one more mode, Average. This mode performs a continuous equal-weighted average, from the time you start the RTA with the Play button in this mode, until you Pause the RTA. Even then, you can continue the average by pressing Play. To reset Average mode, tap the Reset button on the screen.
Play / Pause
Touch the Play/Pause icon to begin. Anytime one of the parameters is changed, the RTA will revert to Pause so that the new parameters can be in effect for the most accurate readings.
Screen Scaling & Resolution
Metasequoia 4 serial id password. Once the graph is running, you can adjust the screen dB scale by sliding the graph and up and down. You can also change the dB resolution showing on the screen by pinching -- pinch together to get more dB on the screen, or pinch apart to get less vertical dB, and thus more detailed resolution. Double-tap the screen to auto-fit the graph to the display.
You can turn on Lock Graph Scale if you want to set a graph range and not have it change on the main screen. The level may still be panned up and down, but the range will not change and the double-tap will not change the scale or range.
Saving a Screen Image
You can take a snapshot of the screen by touching the Save Image button. The image will be saved in your photo roll, and can be emailed or transferred to your computer using various third party apps.

Noise Curve Overlays
To display a noise curve overlay, flip the screen over by touching the info icon in the navigation bar, and select one of the overlays: NCB -- Balanced Noise Curve, RC -- Room Curve, PNC, NR, or Noise Rating, used in the EU, and the cinema large-room X-curve.
The overlay will appear on the graph. To read the noise curve value, find the lowest curve that does not have any bars touching it. You can interpolate between curves to estimate an exact curve number.
Starting in RTA in AudioTools 4.0, now see the overall noise overlay curve value -- in octave mode only, since the noise curve values are only defined for octave band mode.
Graph Weighting
You can select none, A, or C weighting. None will show the actual level of each bar. If you select a weighting, the bars will show the weighted equivalent. This means that the lower frequencies will show lower values in A or C weighting.
Max / Min Bars
You can turn on this option on the setup page. When active, the maximum and minimum levels of each bar is stored, and shown as blue and green bars on the screen.
To reset the bars, just double-tap the screen.
Peak Decay Bars
Peak decay bars will show you the actual peak level of the band, no matter what decay mode you have selected. They automatically decay and will drop into the graph when there is no level above the bar.
Hearing Threshold Line
This line shows the approximate level below which sounds are inaudible to the human ear. This varies somewhat by person, but even so it can be used as a guide to when sounds are not audible.
Overall SPL
The overall unweighted dB SPL level is shown just above the graph, on the right side. Choose unweighted SPL, or A or C weighting on the setup screen.
Audio Monitor
Turn this on to listen to the incoming audio signal in the output. Note that this may cause feedback. Turning on the generator disables Audio Monitor.
Adobe lightroom 2017 for mac torrent. Pink Noise
RTA includes a full-featured signal generator, which includes sine waves, square waves, white noise, and pink noise. Pink noise has equal energy in each octave (or 1/3 octave), so in theory if your system is flat, you will see a flat line on the RTA display.
Room Tuning
In practice, the RTA is really showing the sum of the direct sound as well as the reflections, so this is not 100% correct. Also, most people roll off the high end somewhat, and many like to boost the low end. So, use the RTA and it's information, but also use common sense, and don't make extreme EQ changes. You're usually better off making conservative changes in EQ, but you should definitely try moving speakers and subs around, and watch the effect in the RTA.
Here are some links to learning the basics on room tuning with an RTA:
Smaart v8 is the Industry Leading, Dual Platform (Mac & PC), FFT-Based Audio Analysis Software.
At its core, Smaart is a computer based dual-channel FFT platform that we use in our work as audio engineers to view the frequency content of signals or measure the response of our electrical and electro-acoustic systems, all to better make informed decisions about the deployment and operation of those systems. Getting started with Smaart v8 requires some basic hardware requirements beyond the Smaart software and host computer. At the minimum, for electro-acoustic systems (PA system analysis), a 2×2 audio device interface and a single measurement microphone will suffice. This is however only the beginning, as Smaart is purpose-built to scale up to fit the requirements of even the most complex systems and environments. The only practical limitation of Smaart is your own – be it expanding your hardware universe, or improving your knowledge through practice and training.

Smaart v8 is the most adaptable, intuitive, multi-channel version of Smaart to date. From studio to stadium, shop to show, Smaart v8 fits the needs of any measurement situation.
Representing the next step in modern computer based dual channel FFT analysis; Smaart v8 users will appreciate its intuitive GUI with the straight-forward measurement configuration, controls and data handling processes that have helped make Smaart the most widely used and highly trusted computer based audio measurement platform in the world.
Purchasing a copy of Smaart gives you access to some of the most cutting-edge measurement processes available. The Smaart measurement platform enjoys continual development, implementing expansions which reflect the advancements in our audio industry – not just in equipment and systems available, but also in our collective knowledge as we (…the royal We) develop new tools and techniques. New features are added regularly, not just from our own developmental priorities – but also from requests via our active community of professional users.
Multi-Channel, Multi-Platform, Multi-Window, Multi-Mania
Smaart v8 is inherently multi-channel, multi-platform, and multi-window; able to access modern multi-channel I-O devices and operate native in both Windows and Mac Operating Systems (including 32-64 bit versions). Meaning v8 can run multiple simultaneous Spectrum and Transfer Function Measurements, in multiple windows, all from a single installation of Smaart.
Easy & Intuitive Measurement Configuration
The measurement configuration process in Smaart v8 provides a highly streamlined workflow – with automatic measurement creation and management functionality wherever possible. V8 supports a “build-on-the-fly” process that is often an operational necessity. Specifically:
- The program workflow takes you through device selection/configuration and automatically creates Spectrum measurements.
- Device and measurement configuration is managed in a single window.
- Input metering right in I-O Config – check your inputs even before you’ve created measurements.
- Creating a Transfer Function measurement automatically adds its Spectrum contributors to its tab container.
- Measurement creation on-the-fly from the main interface via menu or Hot-Key commands.
The Most Advanced Data Handling System in Smaart to Date
Smaart v8 introduces the “Session Folder” – and with it the most functionally practical data handling and storage paradigm in the history of the Smaart platform. Pinned to the top of the Data bar, the Session Folder serves as the target location for all new captured data. Automatically named with the current date when created, the Session Folder may be re-named or swapped out at any time. The global program data bar keeps all of your data organized and at your fingertips with nested folders and convenient options such as “New Folder From Selected” or the ability to quickly average selected stored traces of the same type via right select > “Average”.
Touch Friendly Controls
The increased popularity of tablet/touch screen computers complicates the use of its various hot-key commands. To address this, Smaart v8 utilizes a command menu and user-configurable command bar with large touch friendly buttons that can be used to call any of Smaart keyboard-based, hot-key commands.
Smaart-to-Smaart Remote Control
Smaart’s integrated API allows any copy of Smaart v8 to act as a host to any other copy of Smaart v8, meaning you can create a rig with one computer acquiring input signals and performing the measurement computations, while another acts as a client and remotely accesses the measurement data. This capability then allows your v8 environments to be spread not just across multiple monitors, but across multiple computers.
Simple, Friendly, Customizable GUI
Much effort has been expended in reducing unnecessary User Interface (UI) clutter. We give a lot of attention to ensuring the interface is intuitive and that data is presented in a clear and meaningful way. Furthermore, Smaart v8’s highly customizable interface allows you to hide or show any of its control elements – you can see as much or as little of the main UI as needed for any situation. Want to have a full screen plot area during show time? No problem. Want to expand an SPL meter for visibility from afar? Easy. Hot-key or touch commands enable you to quickly change the interface layouts and View-Presets allow you to jump to any pre-set or user-defined plot configuration.
Make Use of the Power
With the relentless expansion of the processing power, speed and memory in personal computers comes the potential for greater measurement power and possibilities – if you can make use of it. Picking up where the Smaart v7 code base left off, v8 is inherently optimized to make use of the power that modern processor configurations present; whether that be from a basic dual core Intel i5, or the most cutting edge power-house processor available. Your Smaart rig might not need to use all your PC’s power right now, but if history is any indicator, you will.
Smaart v8 or Smaart Di?
By design, the data structure and much of the command and control paradigms are the same between both versions of Smaart. The underlying measurement code is the same. That said, there are three functional needs that would prohibit the use of Di;
Rtas Pro Tools 12
- If you need to monitor SPL/Leq or control more than 2 input signals at a time. Smaart Di only supports input monitoring and control for 2 inputs at a time.
- If you need to make multiple simultaneous Transfer Function measurements; in other words, if you need to be able to view two live TF engines at the same time, or live averages of those Transfer Function measurements. Smaart Di only has the ability to measure one Transfer Function at a time.
- If you need to make advanced acoustic measurements, examine reverb times and structure, need to calculate specific intelligibility criterion (like STI, Clarity, T60, etc), then you need Smaart v8. Those capabilities reside in Smaart v8’s Impulse Response Mode, and are wholly omitted from Smaart Di.A chart comparing Smaart v8 and Smaart Di v2 in detail can be found HERE.
