Course itinerary – subject to change
Day 1 (10am – 5pm) Morning
Sound and acoustics basics
Overview of different measurement types
Single channel – dBFS, SPL, SpectrumDual channel – Transfer functions – Frequency domain, Time domain Multichannel – Typical sound system set-up
Brief Smaart 7 overview
What can Smaart v7.5 do? Single channel, dual channel, multichannel
Getting up and running, input level metering
Running Smaart for the first time, getting signals into Smaart Smaart IOSmaart level meter – input dbFS monitoringBasic class set-up, signal distribution checks etc.
Further Smaart metering, microphone calibration & SPL
Microphone channel calibration – using Smaart’s level meter to monitor spl and Leq Tinker time
-Break/set-up debugging, if necessary
Smaart screen areas
Drop-down menus, Help menu Control strip Plot area Data bar
Basic spectral measurements
Spectrum Banding Averaging Tinker time
Spectrograph Dynamic range controls Tinker time
Further spectrograph measurements
Is it the room or the system? Using the spectrograph function for a quick check Spectrograph practice Tinker time
Day 1: Afternoon
Basic transfer function measurements
Review of dual channel techniques – source independence Frequency domain and time domain
Sample rate/FFT size/Time constant relationships, making the right choices Direct or direct + reverb Synchronising Measurement and Reference signals – Delay locator Controller/delay line/equaliser measurement example
Further transfer function measurements
Loudspeaker measurement example Smoothing
Magnitude threshold and coherence blanking
How to deal with a lack of signal How to deal with noise and interference from other sources Further uses of FFT size/Time constant relationships Tinker time for rest of day
Review of earlier stuff, if necessary, before moving on...
Microphone calibration & SPL Spectral measurements Spectrograph measurements Transfer function measurements
Phase, polarity and timing
Phase shift vs time offset and frequency Polarity reversals Effects of multiple source arrivals – combing, and combinations of the above Tinker time
Low frequency boundary effects, sub alignment. Front fill & delay alignment
Cross-over and driver placement effects – polarity/phase
Acoustically small subwoofers and subwoofer arrays – phase rotation caused by boundaries
Front fill imaging considerations
Delay speaker alignment
Tinker time - if the classroom is small (compared to LF wavelengths), sub-main alignment may done outdoors
Day 2 (9am – 5pm) Morning
Subwoofer arrays, reverse-polarity cardioid, in-phase (end-fired) cardioid etc – depends on venue & facilitiesThis is only an introduction. A full, 1-day practical subwoofer array course is available. Contact Jim Cousins for further details.
Working with multiple channels
Lines on the screen vs ear-brain perception -Short break-
Introduction to sound system alignment Stereo system alignmentSingle system near-field alignmentFar-field measurement, coverage, improving intelligibility Stereo matching – matching eq, fine placement adjustments Multiple microphones – trace averaging
Comparing mics, comparing listening positions & system propagation (Dual mic techniques for room analysis will be covered later)
Day 2: Afternoon
The great outdoors
Line array consideration, long-throw propagation, air absorption Outdoor considerations – temperature and wind gradient Longer FFT time constant + smoothing – measuring in windy conditions
Dual microphone techniques Case study – investigating stage sound anomalies using dual microphone techniques
Smaart v7.5’s Impulse mode
Introduction to acoustical analysis, reverberation, intelligibility Tinker time. Room analysis – reverberation & intelligibility measurements
Extras. If time available at the end of the official 2-day itinerary...
Advanced FFT measurement concepts
Data window types Magnitude average types
Session 19 options (advanced measurement session discussions)
(See Session 9a note earlier)
Q & A/General discussion session
Idiot-check! – Have we missed anything specific that you hoped would be covered? Last minute questions Getting help if you hit a snag when using Smaart in the real world
- Finish & get-out -
Run by Shure Distribution UK, Wireless Mastered aims to demystify the world of wireless by providing an in-depth look into RF Technology and the recent changes to spectrum allocation.
Additionally, attendants will have the chance to gain hands-on training with Shure's industry leading wireless products, including: Axient, ULX-D, QLX-D, & PSM1000.
