SoundMeter

       iOS Universal

SoundMeter turns your iOS device into a handheld sound level meter (SLM). The built-in and headset microphones are suitable for certain, basic sound level measurements, but high precision external microphones may also be used with appropriate interface hardware.

Even though default sensitivity values are included for the built-in and headset microphones, for best results, SoundMeter should be calibrated before use. Sound levels may be off by a few dB when using the default microphone sensitivity.

For iPhone/iPad/iPod touch audio I/O compatibility and frequency response measurements, visit http://blog.FaberAcoustical.com.

NOTE: SoundMeter has not been shown to meet ANSI or IEC standards for sound level meters.

FEATURES
- Measure time-weighted and equivalent sound levels.
- Employ Flat, A, or C frequency weighting.
- Time-weighted measurement options include Fast, Slow, and Impulse weightings.
- Keep track of peak and maximum sound levels.
- Save high-resolution sound level display images to PDF files or to the device’s Camera Roll photo album. Descriptive text may be added to the image before it is saved.
- SoundMeter also offers data sharing via photo and email.
- Calibration controls enable automatic calibration, relative to a calibrated sound level meter, or manual entry of the microphone sensitivity.
- SoundMeter supports rotating an iPhone upside down, so the built-in microphone sits on top of the device when measuring sound levels.
- With an iOS device’s built-in microphone or a standard headset microphone, SoundMeter can measure peak sound levels of up to approximately 130 dB. (These limits are due to the hardware, not the SoundMeter software.) Results may vary between iOS devices and headset microphones.

What's new

Version 3.0.1
- SoundMeter uses less memory on iPhone and iPod touch, which corrects potential graphics issues with in-app upgrades on older devices.
- Corrects an issue which prevented proper updating and redrawing of the horizontal and vertical axes of the Octave tool display.
Version 3.0
- Octave-band RTA, FFT Analyzer, and Oscilloscope tools are now available within SoundMeter via in-app purchase.
- A data acquisition upgrade is also available via in-app purchase, which includes an http server for downloading files exported from any of the analysis tools. It also enables CSV and MAT file export from the FFT, Octave, and Oscilloscope tools, plus additional engineering units (V, A, g, and ips) can be assigned to input signals.
- Corrects a potential crash when accessing the image picker on iPad.
- Twitter support has been restored (in iOS 5) for tweeting sound level data.
