SoundMeter Pro 2022 is not recommended for new purchases. SoundMeter X offers perpetual license and subscription options for the latest tools and features. SoundMeter Pro 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 (RTA). 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. Features: - User-defined custom metadata in saved audio and data files - Level Meter -- Lp, 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. -- View auxiliary sound level or octave spectrum display with the device in landscape orientation. - Noise Dosimeter -- 8-hour Noise Dose, Projected Dose, TWA calculations -- Criterion Levels: 80, 85, 90 dB -- Exchange Rates: 3, 4, 5 dB -- Data logging.
