【免費工具App】Sound Level Analyzer-APP點子

"Sound Level Analyzer" is a sound level dB meter and real-time signal analysis tools for the iPhone.It can be displayed the sound level measurements and signal analysis simultaneously, and is available in a variety of applications such as the neighboring environmental noise measurement and sound check of Live events."Sound Level Analyzer" has our advanced digital signal processing algorithms to process acoustic frequency weighting filter and to measure real-time sound levels. The ANSI acoustic filters are A-weighting and C-weighting. A-weighting filter is provided a roll off of low frequencies and high frequencies fairly steeply for human ears. C-weighting filter is provided a roll off of low and high frequencies slightly for music. The response time of all measurements can be also selected from ANSI Fast or Slow parameter."Sound Level Analyzer" also has three modes of sound signal analysis function, which are Time-domain Graph, Frequency Spectrum Analyzer and FFT Analyzer. Time-domain Graph is a sound level time chart and works by plotting the measured sound level for the last 20 seconds, applying a weighting filter.Frequency Spectrum Analyzer is based on our Real-time Audio Analyzer app "fo-Kannon", and is provided 1/3 Octave-band frequency spectrum analysis of input signals, applying a weighting filter.FFT Analyzer is also provided the Fast Fourier Transform Analysis of input signals, applying a weighting filter."Sound Level Analyzer" comes pre-calibrated for the built-in mic, but you can adjust the calibration if you have a calibrated standard sound level meter. For a more detailed acoustic analysis, please consider our Audio measurement tools, the iPhone app "Audio Frequency Analyzer " and the iPad app "fo-Kannon RTA". TOON,LLC is a company that seeks the comfort of sound environment based on our acoustic proprietary technology, and we will provide tools for audio professional, sound technology, home theater installer, and anyone who loves audio. Features:- Sound Level Measurement: Leq(equivalent continuous sound level), Lmin(Minimum sound level of Leq), Lmax(Maximum sound level of Leq)- Display level dynamic range: 0 - 130dB - Supports frequency weighting filter: A, C, and Z(without filter). - Supports Time weighting: 125ms (Fast), 1sec (Slow)- Frequency range: 20Hz - 20kHz- Calibration function: offset value from -20.0dB to 20.0dB- Display resolution: 0.1dB- Peak measurement range: around 110dB (by built-in mic performance)- Pause the screen during measurement- Setting of measurement duration: 10sec - 1hour, Infinite (Default setting: 60sec)- Time-domain Graph function: Sound level graph chart (TIME mode)- Frequency Spectrum Analyzer function (1/3 Oct mode)- FFT Analyzer function(FFT mode)- Capture the measurement results with Time-stamp and GPS location data to Camera-roll.Applications:- Live Sound - Environmental noise measurement - Installation of audio equipment - Tuning of audio equipment - Architectural acoustics - Broadcast - Device managementNote:This app is adjusted the reference value for iPhone. However, the built-in microphone of your iPhone is likely to have a non-uniform gain. The more exact measurement should be calibrated using the absolute level calibration devices. At the time of the first access to built-in Microphone and Photos after installing the app, you will be asked authorization to access them by the iOS system. If you do not enabled this setting, the app can not access them by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy > Photos or Microphone".Please visit our iOS App Support page for more information on this app.
