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.

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. The free download includes a sound level meter tool, which supports time exponential weighted sound levels, Lp, with flat frequency weighting and fast time weighting (LpAF). Additional tools and features are offered via auto-renewable subscriptions.
