Features & Capabilities

SoundMeter X turns your iPhone or iPad into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, stereo signal generator, multi-channel data recorder, and real-time whole or 1/3 octave band spectrum analyzer (subscription required for most features--try it out with a 14-day free trial).

Input signals can be acquired from the current (manually selectable) audio input path. Sensitivity calibration can also be performed for any audio input device and/or input channel. Direct hardware support (automatic sensitivity calibration, based on factory-defined values) for The Modal Shop’s 2-channel 485B39 USB-ICP interface and miniDSP’s UMIK-1, UMIK-2, and E.A.R.S. microphones.

In addition to real-time sound level measurements, SoundMeter can stream raw sound data to audio files, and store acquired sound level data, including date, time, and location, in CSV or TXT (tab-delimited) files, MAT-files, or high-resolution PDF images for later retrieval from your device.

SoundMeter may be downloaded for free from the App Store. Additional tools and features are offered via auto-renewable subscriptions.

The SoundMeter Pro subscription includes:

  • User-defined custom metadata in saved audio and data files
  • Level MeterLp, Leq, Lx sound levels -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. -- Event notifications
  • Max Levels Meter -- Traffic-light-style meters make it easy to monitor 2 separate sound level thresholds in 2 independent user-defined frequency bands. -- Define lower (warning) and higher (limit) sound level thresholds for overall (full audio band) levels as well as for individual octave frequency bands. -- Store user-defined thresholds in files for later recall.
  • Noise Dosimeter -- 8-hour Noise Dose, Projected Dose, TWA calculations -- Criterion Levels: 80, 85, 90 dB -- Exchange Rates: 3, 4, 5 dB -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks.
  • Real-time Octave Spectrum Analyzer (RTA) -- Lp, Leq, Lx sound levels -- Supports whole or 1/3-octave frequency bands -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- NC, RNC, and NR references curves, NC, SIL, and NR values -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks.
  • Multi-channel Data Recorder -- Supports up to 8 channels -- Live monitoring of recorded data -- Metadata (including calibrated sensitivity) embedded in audio file (AIF, CAF, WAV), optionally saved in separate data file
  • Stereo Signal Generator -- Left and right outputs assigned to arbitrary hardware output channels -- Random and pseudorandom (periodic) noise sequences with white or pink spectrum -- Linear and logarithmic frequency sweeps -- Dual periodic waveforms with arbitrary frequency and phase difference

The Pro Tool Set subscription can be shared between SoundMeter X and SignalScope X. It unlocks all tools and features of the SoundMeter Pro subscription in SoundMeter X and all tools and features of the Pro Tool Set subscription in SignalScope X (iCloud login required).

User Reviews

SoundMeter X has a solid core metering function that many users find reliable and suitable for professional use, with praise for its intuitive UI. However, widespread dissatisfaction centers on its business model: high, multi-tier subscriptions, paywalls, and pressure to upgrade, which can render older purchases unusable. Some reviews also cite limited value of the free tier and occasional reliability/accuracy issues tied to OS updates. Overall, value depends heavily on willingness to pay and tolerance for ongoing licensing changes.
Pros
  • Core metering functionality is reliable and does what it promises.
  • App is useful for professional work and praised for reliability and productivity.
  • User interface is intuitive and easy to use.
Cons
  • Expensive, subscription-based pricing with multiple add-ons and ongoing charges.
  • Loss of access to previously purchased apps/tools due to upgrades or removal from the App Store.
  • Most features require a subscription with the free version offering limited functionality.
  • Reliability and compatibility concerns, including reports of accuracy issues and bugs related to updates.
Recent reviews
This meter consistently reads 30 decibels higher and should not be considered accurate.

I installed Sound Meter years ago and spent under a hundred dollars upgrading tools. Now I cannot even access the purchased tools because of unfettered profit subscription and decision not to support prior legacy sales. Do not buy services! Any company that sells add -ons for 100 dollars, then discontinued legacy support cannot be trusted.

Several years ago I bought the whole suit of apps from this company only to find out recently that all the products I bought have been rendered non-functional by them. Instead of being able to use the apps I already paid for, they want me to pay buy new versions. The developer response to other similar comments is you can still use your old app. If you buy a new device, you can't because they removed the old app from the App Store! What a bunch of crooks!!
