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 -- 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 - 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.) The SignalScope X 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).

  • Simulates acoustic product impact
  • Calculates required acoustic elements
  • Organized product catalog by category
  • How-to video guide
Features
Read full description

The BuzziSpace RT60 app is a functional tool that measures reverberation times in small- to medium-sized rooms. In addition to calculating current reverberation levels, the RT60 app allows users to simulate the impact of various BuzziSpace acoustic products on the acoustics of a room and thereby determine the number of acoustic elements required to reduce reverberation times to acceptable levels. The product catalog changed is presented in a more organized arrangement of acoustic solutions by category. These categories are listed as: Wall Mounted, Ceiling Suspended, Acoustic Lighting, Acoustic Furniture, Free-Standing, and Partitions & Screening. By grouping our various acoustic solutions according to these categories, we aim to simplify the process of identifying and adding products to acoustic simulations within the app. A How-To video to walk you through the app has also been added. This video can be accessed via the menu in the app. For additional help, reach out to: www.buzzi.space/contact.

Verdict

The call

The clearest difference is rating: SoundMeter X at 3.6 against BuzziSpace RT60's 2.7. SoundMeter X also leads on update cadence (every 5 weeks vs every 4 months) and ratings volume (45 vs 3). BuzziSpace RT60's advantage is in-app purchases (none vs 7) and iOS requirement (15.6 vs 18.6). On price, review sentiment, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

SoundMeter X holds the better App Store score, 3.6 against 2.7. That said, the two scores are not equally well evidenced: SoundMeter X has 45 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 23% of SoundMeter X's written reviews are positive against 25% of BuzziSpace RT60's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SoundMeter X ships an update every 5 weeks, BuzziSpace RT60 every 4 months. The most recent releases landed on September 21, 2026 and September 13, 2026 respectively.
