HouseCurve is a multi-tool for audio systems. Use it for room correction, adjusting equalizers, setting subwoofer phase, choosing crossovers and more. Features: * Sine sweep and real time pink noise measurements * Sweep measurements can be averaged as they are collected * Alternatively, use real time tool to collect moving mic measurements (MMM) * Compare measurements to a selected target curve * Create and edit target curves * Generate room correction filters (PEQ or FIR) * Filters compatible with a variety of systems including Roon, Volumio, CamillaDSP, EqualizerAPO, miniDSP and Crestron DM NAX * Display magnitude, phase and group delay * Use with built-in or external microphones * Connect with AirPlay, Bluetooth, headphone jack (analog) or use external stimulus HouseCurve measures in-room frequency response by listening to your audio system play a sine sweep. Measurements are displayed on top of a target curve, making it easy to see where adjustment is needed. Multiple measurements can be averaged to fully capture how the system sounds in the listening area. With small changes and repeat measurements, you can manually tune your system to the target curve. If your audio system has a parametric equalizer or convolution engine, HouseCurve can automatically generate filter settings to match the target curve. HouseCurve can help with home and car audio system tuning, from system equalization and room correction to subwoofer time alignment and speaker placement. Visit housecurve.com for more information on how HouseCurve works and how to use it. HouseCurve will produce acceptable results with the built in iPhone/iPad microphone. Using calibrated external microphones will provide higher accuracy. The free version of HouseCurve can measure your audio system and display a magnitude plot (aka "frequency response"). Additional features, such as room correction filter generation, advanced measurement tools and target curve editing can be obtained via in-app purchases.

  • Basic acoustic data (RT60, Schroeder Freq, Volume)
  • Unlimited room scanning
Read full description

Acoustics just got easier. Scan your room with LiDAR, then see its room modes, simulate where a speaker could go, and export the geometry for your own simulation work. Part of the growing amcoustics-tools family, built on amroc THE room mode calculator. Capture your room's geometry once, and work from that one scan. It's a game-changer for anyone who has ever used the popular amroc and amroc pro calculators. For whom this app is for: audiophiles, home theater enthusiasts, home studio owners, and professional acousticians who want to see the acoustic behavior of a room in 3D without the hassle. Discuss listening positions, speaker placement, and absorber strategies while seeing the modal behavior of your room. A LiDAR-enabled iPhone or iPad is required to use scanning feature! How it works: 1. Open the app and scan your room with your device's Lidar sensor. 2. The app automatically creates a 3D model. 3. You can calculate the first 5 room modes for free. 4. From there, choose what you want to do with the room: see all relevant modes, run a speaker placement simulation, or export the geometry. 5. Each of those is an in-app purchase, calculated once for that room. What's included: - Free to Download: The app is completely free to install. No upfront charges, no login. Just install and use. - Unlimited Scanning: Scan as many rooms as you like. - 5 Free Room Modes: Instantly calculate and visualize your first five modes for every room you scan. - Basic Acoustic Data: Reverberation time estimate, Schroeder frequency, and room volume. - All Room Modes: Use the in-app purchase to get all relevant modes, up to roughly the Schroeder frequency. Sweep through the frequency range and play the selected mode through your speakers, so you can hear the resonance while you see it. - AR Preview: Place the scanned room and its modal pattern in front of you through the camera, and walk around the model. - Speaker Placement: Set your listening position, and the room is simulated from there. You get a map of how even the response would be at every point in the room, and you can place up to two speaker positions and compare their frequency response curves side by side. - Export Simulation Geometry: Download a low-polygon, closed, watertight and manifold mesh in OBJ, STL, DXF, STEP or DWG. This allows you to perform any type of simulation you desire later, in the software you already use. About the speaker placement: This is a simulation, not a measurement. It is calculated from the geometry we scanned, so it will not match a microphone in your room exactly. Use it to understand how your room behaves at low frequencies. Decide where to start from, then trust your ears. amscan transforms complex acoustic calculations into a simple, visual, and intuitive process. Stop guessing and start designing your sound.

Verdict

The call

HouseCurve and amscan both sit at 4.7 stars, but that hides the real split: 81% of HouseCurve's written reviews are positive against 50% of amscan's. HouseCurve also leads on ratings volume (264 vs 5). amscan's advantage is update cadence (every 11 days vs every 2 months). On price, rating, ads and in-app purchases there is nothing between them.
