Room
Room measures a listening room or recording studio with a Mac, an iPhone or iPad Pro and an Apple TV. Room Scan's LiDAR maps where each speaker sits and which way it points. Room then plays music you know to measure the response at your seat and the bass across the room.
Room costs $9.99 on the App Store, once, and covers the Mac, iPhone, iPad and Apple TV. It is in App Review now.
Measured with your music
Room measures with the tracks you already use to judge a system, played at listening level through your own AV receiver or audio interface. The Apple TV, iPhone and Mac share one clock. Every recording lines up with the music that played.
No sweeps
Any track in your library works, played at your listening level through your own chain and room.
Response and coherence
Room compares each recording with the original track. Each comparison gives the frequency response and arrival time at every position. Coherence shows which parts of the result to trust.
Before and after
Move a speaker, add a panel or change the sub level, then measure again with the same track and compare.
What it measures
Speakers
Room Scan uses the LiDAR to place every speaker from 2.0 to 7.1, with its position, height and direction. Every speaker also gets a near-field response and a channel check.
Listening position
Room gives the frequency response at your listening position. Your seat and the screen both go on the room plan.
Bass across the room
Room maps the bass response at every position you measure, so you can see where modes build up and where nulls fall. In our test room, 40–120 Hz varied by 25.7 dB across 38 positions.
Room plan
LiDAR maps the walls, beams and speakers. Room gives the distance from your seat to each speaker in feet and inches.
On your TV
Room View shows the room plan and the results on the big screen.
Low, Mid, High, Full
Results come in four frequency ranges. Low covers the sub and the crossover region.
Where it stands
Room is at version 0.1. So far we've measured one room, a 5.1 system in a space about 20 ft square, using an iPhone 14 Pro. A phone's mic isn't a measurement mic, so Room shows each response relative to the others. Apart from the spacing of the front pair, we haven't yet checked Room against a tape measure or a calibrated mic. The white paper has the detail.
What's coming
Levels and distances
Room will measure channel levels and distances from your seat, ready to enter on your AV receiver.
Sub and crossover
Room will show how the sub and the mains blend through the crossover, so you can set the sub level and crossover frequency from the result.
Placement
Room will say where to move each speaker and which way to point it. A suggested seat will keep you out of the worst nulls.
Treatment
First reflection points will go on the plan, along with the positions where bass traps will do the most.
Room modeling
A model built from the LiDAR scan will predict the bass for a new speaker or seat position before you move anything.
AV receiver control
Room will set levels directly on Denon, Marantz, Yamaha and Onkyo receivers over your network, and distances on the receivers that allow it.
We also plan support for USB measurement mics such as the miniDSP UMIK-1, export to REW, and Dirac Live and Audyssey mic positions on the TV.
Requirements
- A Mac on macOS 13 or later.
- An iPhone or iPad Pro with LiDAR: iPhone 12 Pro or any later Pro model, or an iPad Pro with LiDAR.
- An Apple TV 4K on tvOS 17 or later, connected by HDMI to your AV receiver or audio interface.
- Music as files you own. Room can't play from streaming services.
What Room leaves alone
- Room doesn't apply EQ or room correction. Keep running Dirac, Audyssey or your receiver's own correction.
- Room doesn't change your Mac's audio output or your receiver's settings.
- Your measurements stay on your Mac.
