Pi System Align
Measure it. Align it. Prove it.
Dual-channel measurement and alignment for sound systems. Measure transfer functions, find delays, align crossovers — and know exactly where to put the microphone.
Every seat bought the same ticket. Pi System Align makes sure they hear the same show.
What it does.
Everything you measure
Transfer function, spectrum, impulse response and SPL meter in one window.
Delay finder and arrival times
Find the delay between reference and measurement automatically and see arrival times for every system.
Crossover alignment
Align mains to subs, fills and delays with phase and magnitude side by side.
Mic placement assistant
Describe the room and systems and get suggested mic positions for mains, subs, fills and delays — with the reason for each.
Delay calculator
Distances in, delay times out, ready to dial into the processor.
Practise anywhere
A built-in virtual PA with a sub and a delay tower lets you learn every feature without an interface.
From empty arena to aligned system.
Walk the room with one mic, capture traces, average them and align. Pi System Align tells you what to change and by how much.
The right mic, in the right place.
The assistant explains each position: reference, near check, edge left and right, so measurements are repeatable and defensible.
