Question 1

What is room correction?

Accepted Answer

Room correction is a technology that measures how your room affects sound and creates digital filters to compensate. Every room has acoustic problems—reflections, standing waves, and absorption—that color the audio you hear. Correction filters counteract these effects for more accurate sound reproduction.

Question 2

Do I need special equipment?

Accepted Answer

You need a calibrated measurement microphone (USB microphones like the miniDSP UMIK-1 work great and cost around $100). A microphone stand is also helpful for consistent positioning. Sounn supports calibration files from major manufacturers including miniDSP, Earthworks, and Dayton Audio.

Question 3

Will room correction work in my room?

Accepted Answer

Room correction works in any room, but the degree of improvement varies. Rooms with moderate acoustic problems see the most benefit. Severely problematic rooms (very live, extreme dimensions) benefit most from acoustic treatment combined with correction.

Question 4

Is Sounn available for Windows?

Accepted Answer

Currently, Sounn is exclusively available for macOS. We built it as a native macOS application using SwiftUI to provide the best possible performance and user experience on Mac. There are no current plans for a Windows version.

Question 5

How many measurement positions do I need?

Accepted Answer

We recommend 3-5 positions for most home setups. The primary listening position is most important, with secondary positions creating a broader sweet spot through averaging. Sounn supports up to 9 measurement positions per session.

Question 6

Why does my quality score seem low?

Accepted Answer

A low quality score reflects genuine room acoustic issues, not a problem with your measurement. It means there are significant issues that correction will improve but may not completely solve. Consider acoustic treatment for very low scores.

Question 7

Do I need to import a microphone calibration file?

Accepted Answer

For best accuracy, yes. Calibration files compensate for your specific microphone's frequency response. Most measurement microphones come with a calibration file for your unit's serial number.

Question 8

How often should I re-measure?

Accepted Answer

Re-measure whenever you make changes to your room—moving furniture, adding/removing treatment, repositioning speakers. Also consider re-measuring seasonally, as temperature and humidity affect acoustics.

Question 9

Does room correction add latency?

Accepted Answer

Yes, digital correction introduces some processing delay. Typical latency is 20-80ms depending on settings. This is usually unnoticeable for music and movies (most players can compensate), but may be noticeable for gaming or live monitoring.

Question 10

What smoothing setting should I use?

Accepted Answer

Start with 1/6 octave for a balanced approach. Lower values (1/12, 1/24) provide more detail but risk over-correction. Higher values (1/3, 1/1) are more stable but less precise.

Question 11

How much boost is safe?

Accepted Answer

We recommend limiting boost to 6-9 dB. Higher boost demands more amplifier power and can stress speakers. Deep nulls that "need" more boost usually require acoustic treatment instead.

Question 12

Which target curve should I choose?

Accepted Answer

Flat is best for mixing, mastering, or reference listening. House Curve A/B provides a more relaxed, enjoyable sound for casual listening with bass boost and treble roll-off. Harman In-Room is a research-based preference curve that's a good all-around choice.

Question 13

Can I undo correction if I don't like it?

Accepted Answer

Yes! Simply disable processing from the Dashboard. Your original audio path is unchanged—correction is applied in real-time and can be toggled on/off instantly.

Question 14

What's the difference between FIR and IIR filters?

Accepted Answer

FIR (Finite Impulse Response) filters offer linear phase and precise correction but require more processing power—best for mid/high frequencies. IIR (Infinite Impulse Response) filters are efficient with low latency but introduce phase shift—best for bass frequencies. Sounn uses both in a hybrid architecture for optimal results.

Question 15

What speaker configurations are supported?

Accepted Answer

Sounn handles everything from stereo (2.0) to full Dolby Atmos 7.1.4 and custom configurations up to 34 channels. Perfect for home theaters, music production studios, and audiophile listening rooms.

Question 16

Does Sounn work with Apple Music / Spotify?

Accepted Answer

Yes! Sounn applies system-wide correction, so it works with any application that outputs audio on your Mac—streaming services, video players, DAWs, games, and more.

Question 17

What are the system requirements?

Accepted Answer

Sounn requires macOS 12.0 (Monterey) or later and works on both Apple Silicon (M1/M2/M3) and Intel Macs. Minimum 4GB RAM and 500MB storage. For best performance, we recommend macOS 14.0+ and Apple Silicon M1 Pro or better.

Question 18

Is this a subscription or one-time purchase?

Accepted Answer

Sounn licenses are one-time purchases. You pay once and own the software forever. Standard is $399 and Professional is $999. No subscriptions, no recurring fees.

Question 19

What's the difference between Standard and Professional?

Accepted Answer

Both licenses provide full 20Hz-20kHz correction. Standard supports up to 7.1.4 configurations with 2 device activations. Professional supports up to 34 channels, advanced 1/48 octave smoothing, phase correction options, 3 device activations, and priority 24h support.

Question 20

Can I transfer my license to a new Mac?

Accepted Answer

Yes. Deactivate your license on the old Mac (Settings > License > Deactivate), then activate on your new Mac. Standard licenses typically allow 2-3 device activations.

Question 21

How many devices can I activate?

Accepted Answer

Standard licenses allow 2 device activations. Professional licenses allow 3 device activations. You can deactivate and reactivate on different Macs as needed.
