## Description

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 or perpetual license required for most features--14-day free trial available).

Input signals can be acquired from any available 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 EARS 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 in-app purchase.

The SoundMeter Pro subscription includes:
- User-defined custom metadata in saved audio and data files
- Level MeterLp, Leq, Lx sound levels

    -- 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.
- 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

    -- 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
- MultiTool
    -- Powerful data monitoring and project management (Add 2-6 subtools, depending on screen size, and save configurations for easy recall at a later time.)

## Review summary

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.
