![]() Where I find target curves to be handy is in setting up cinema systems to the X-Curve, or to display NC rating contours to determine the noise floor of the room, or to properly optimize a noise masking system. Keep in mind that you want your mic levels (and target curves) to be properly calibrated to dB SPL. You can create your own by simply modifying a captured spectrum measurement. It should be noted that the target curves in Smaart only work in Spectrum mode. Or simply use MTW in Smaart, put the mics at ear height (or do a ground plane measurement) and rely on the coherence curve to help you navigate your way around the limitations of your measurement. Or put the mics up really high off the floor, now you can window out the reflections without taking a "hit" on the LF resolution (because you can have a larger time window), but you no longer see the boundary effects in your measurement. It is more challenging to window out those reflections while getting sufficient resolution in the LF because the reflection path is relatively short. Which opens up a measurement can of worms.put your measurement mics at ear height, so that you can see the boundary effects of the floor, but at the same time you're having to deal with the cancellations from the floor reflections you typically see in your measurement. 12 ft in open space, and you will see a change in the LF, even a few dB. Get yourself a 12 ft stepladder, and listen/measure the system at a seated listening height vs. Our ears have grown accustomed to this phenomenon, hence why it's desirable to hear sound systems tuned this way. so listen.įWIW In 2015 I'm seeing more and more people listening (and mixing) with their eyes :roll:Īctually that low frequency "boost" you mention has more to do with the position of our listening plane (our ears) being close to the floor, consequently we are hearing the boundary effect on the low end response of the system. There will of course be some things that you can not fix with EQ, and should not try to fix. I would just make sure what your are doing has a smooth Smaart trace, has a gentle boost in the low end, and sounds natural. … and that's why some measurement programs are now starting include“Target Curves” that are not "flat". That’s why we tend to prefer systems with in-field Smaart measurements that are not quite flat and appear to have transfer functions that have a gentle low frequency boost. It’s tricky, we as sound engineers have to match our hearing’s perception with EQ. Our hearing does all sorts of cleaver stuff and our perception does not quite match what Smaart measures. A full suite of acoustic analysis tools for impulse response measurements, including reverberant decay and intelligibility criterion.For a speaker to sound correct it should measure flat in an anechoic chamber, if we use an FFT measurement with a sample time long enough to capture the low frequencies in a typical live sound environment it will capture other stuff as well.Smaart-to-Smaart API remote control allows any copy of Smaart v8 to act as host to any other copy of Smaart v8 on the same network.Touchscreen-friendly user-configurable command buttons to accommodate increased use of Smaart on tablet and touch screen computers.Broadband metering for all input devices allowing users to continuously view input signal levels as well as monitor and log parameters such as SPL and LEQ for multiple inputs simultaneously.Intuitive measurement configuration that dramatically speeds up workflow.It is like being able to run multiple measurement sessions simultaneously. Multi-Window capability allowing users to drive multiple windows, each containing its own set of tabbed workspaces.A tab-based interface allowing users to configure and switch between multiple workspaces without opening multiple windows.The only practical limitation of Smaart is your own – be it expanding your hardware universe, or improving your knowledge through practice and training. ![]() 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. At the minimum, for electro-acoustic systems (PA system analysis), a 2×2 audio device interface and a single measurement microphone will suffice. Getting started with Smaart v8 requires some basic hardware requirements beyond the Smaart software and host computer. 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. ![]()
