What's New in SoundMeter 2D
4.01
October 30, 2026
This update takes your sound maps off the screen and onto the real floor. • Heatmaps in augmented reality: lay SPL and uncertainty maps on the floor and walk through them, band by band. Quality indicators are one tap away, and you can film the view to share it. • Drift control: a live tracking indicator and a four-corner recalibration keep your points anchored to the real floor. • Pick up where you left off: re-anchor a saved project in AR another day and keep measuring. • Revised quality indicators: their calculation has been reviewed, and a clear verdict now combines blind-test cross-validation and coverage checks, with concrete next steps. • External measurement microphones: load your mic's calibration file and confirm it matches the connected microphone before it is applied. • Frequency response anywhere: tap any spot on the map to see all 31 third-octave bands, each with its uncertainty. The method behind SoundMeter 2D was presented at ICSV32, the 32nd International Congress on Sound and Vibration, in Istanbul.

FAQ
What is SoundMeter 2D used for?
SoundMeter 2D turns your iPhone or iPad into a sound field mapping instrument. It allows you to place measurement points in augmented reality, record sound data, and then visualize where your room is loud or quiet with detailed heatmaps.
Does SoundMeter 2D have ads?
No, SoundMeter 2D does not contain advertisements. The app is free to download and use, with optional in-app purchases for advanced features or subscriptions.
What are the subscription options for SoundMeter 2D?
SoundMeter 2D offers weekly ($2.99), monthly ($5.99), and annual ($59.99) subscription plans. The annual plan includes a 7-day free trial.
What kind of sound analysis does SoundMeter 2D perform?
SoundMeter 2D performs third-octave analysis from 16 Hz to 16 kHz, interpolating the sound field using Gaussian Process Regression. It provides maps of estimated sound pressure level (SPL) and spatial uncertainty.
Can I see the sound maps in the real room with SoundMeter 2D?
Yes, SoundMeter 2D features AR heatmaps that you can lay on the floor of the real room. You can walk through these maps to visualize sound peaks and dips at ear height.
What devices is SoundMeter 2D compatible with?
SoundMeter 2D is compatible with iPhone and iPad devices. It offers portrait and landscape layouts on iPads.
How does SoundMeter 2D ensure accuracy?
The app uses anisotropic GPR interpolation, drift control with recalibration, and statistical pre-processing like outlier rejection. It also provides a result quality verdict based on cross-validation.
Can I export my sound mapping results from SoundMeter 2D?
Yes, SoundMeter 2D can generate structured PDF reports. These reports include campaign summaries, point layouts, and detailed band-by-band analysis.
