SoundMeter X

SoundMeter X turns your iOS device into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, multi-channel data recorder, and real-time analyzer (RTA). Input signals can be acquired from the current audio input path (iOS automatically selects the audio input path according to which external audio devices, if any, are connected to your iOS device). Sensitivity calibration can also be performed for any audio input device 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: - 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. - Octave 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 -- 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. - 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 - 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).
