The following slide show contains thirteen Android and Apple audio apps for audio spectrum analysis. ‎"Decibel X" is one of very few noise meter apps on the market that has highly reliable, pre-calibrated measurements and supports dBA, dBC. Besides, the application can be used as a measuring instrument of noise level (not for exact measurements).• Sound wave.• Fast fourier transform (FFT). The minimum height of the peak for octave bands is 2 dB.• Interpolation of frequencies in the list of peaks. Keep in mind, there are other software and hardware solutions for RTA sound frequency analyzers, but at $300+ the cost is significantly more. I never see the save txt option, it only gives you wav file. Instructions for use could use better detail and explanations for users not so versed in audio analysis. With Family Sharing set up, up to six family members can use this app. Hitting something). Soundbeam helps you see what everyday sounds look like and visualizes sounds you can’t even hear! Spectrum Analyze gives you real-time spectrum data from the microphone on your Android device. These apps cover a range of audio measurements, some measure RTA and others FFT, they also range in data presentation - some display 2-D graphs, both logarithmic and linear, and others display 3-D content with waterfall graphs. "Sound Level Analyzer" is sound level meter and sound analysis tools for iPhone.Available in variety of applications as the neighboring environmental noise measurement, audio system check, vehicle interior noise check, sound check of live events, and more. This app is available only on the App Store for iPhone. Has paid options for more features, but doesn’t shove them in your face. The SoundMeter app on the iPhone 5 (L) and iPhone 4S (R) compared to ½” Larson-Davis 2559 random incidence type 1 microphone (C). Please let me know if you have any other ideas for improvement. Keep in mind, there are other software and hardware solutions for RTA sound frequency analyzers, but at $300+ the cost is significantly more. "Audio Frequency Analyzer" is a powerful Real-Time Audio Analyzer (RTA) app for the iPhone. Calibrated with professional dB meter. Download Sound Level Analyzer and enjoy it on your iPhone, iPad, and iPod touch. Still, I like the app, but hope it gets better. These settings are visible in the penultimate screenshot (in the App Store). Files with saved data (SavedData_[date]_[time].txt) can be copied to a desktop/laptop computer or transferred to another iPhone using iTunes. Also, has no indication or selection of which microphone on the iPhone is active. Available in variety of applications as the neighboring environmental noise measurement, audio system check, vehicle interior noise check, sound check of live events, and more. You can move over all collected data. The following slide show contains thirteen Android and Apple audio apps for audio spectrum analysis. Ultrasonic Analyzer is a real-time spectrum, spectrogram, oscilloscope and octave RTA analyzer for your iPhone or iPad. ‎This app supports simultaneous display of "audio waveform" and "amplitude spectrum" (size of FFT calculation result for each frequency) for audio signals input from a microphone. Plug in your electric guitar, a mic or any other (hi-Z) device to your mini-jack input and get accurate measurements. The Sound Frequency Analyzer app analyzes the audio spectrum of the sound … If you have not enabled this setting, the app can not access them by privacy restrictions of the iOS system. Great for quickly looking at the frequency of sound. Features as sound meter (decibel meter): Compatible with iPhone, iPad, and iPod touch. (display Max)# Control function- Calibration function : level correction value setting, -20 to +20dB- Measurement timer function : 1 minute / 5 minutes / 10 minutes / 15 minutes / 20 minutes / 30 minutes / 1 hours- Snapshot : Save measurement display with time stamp to Photos. ESTIMATE THE TOTAL NOISE LEVEL BY USING THE SOUND WAVE MODE AT THE MAXIMUM VALUE.• Sample rate: 48000 Hz.• Taking a screenshot by lightly touching the screen.• Export data to a WAV or text file ("Y=[y1 y2... yn]", "y1;y2;... yn", "x1;y1\nx2;y2;..."). Have reverted back to ver 1.1. Watch the dancing spectra on your phone by simply placing your phone near a your media player, car stereo, or radio while playing music. FFT size: 2048 (the accuracy of determining the frequency of ±12 Hz), 4096 (±6 Hz), 8192 (±3 Hz), 16384 (±2 Hz), 32768 (±1 Hz), 65536 (±0.5 Hz), 131072 (±0.2 Hz).• Linear and logarithmic frequency scale.• Linear frequency scale with maximum details (there is a choice for the displayed frequency range).• Linear and logarithmic amplitude scale.• Octave bands (1/1, 1/3, 1/6, 1/12).• Window functions (Blackman, Hamming, Hann (Hanning), Blackman–Nuttall, Gaussian, Flat top).• A- and C-Weightings.• Peak hold.• Exponential spectrum averaging.• Peak frequency detection.• Values of any point (for frequency scale and sound wave (at maximum detail)).• Sound level meter (dB SPL). Copyright © 2020 Apple Inc. All rights reserved. Surprised me with sound spike detection, to show frequencies of short bursts of sound (ex. Thanks for the suggestions! Compatible with iPhone, iPad, and iPod touch. It is necessary to select the data export format in the app settings. ‎"Sound Level Analyzer" is sound level meter and sound analysis tools for iPhone. Free Sound Analyzer For iPhone. Doesn’t even explain if it’s using a specific mic, or an average of all the mics. Ver 1.2 stops sampling when iPhone locks. Apple iOS and Google Android platforms account for 93% of those devices [Nielsen, 2013]. It does the sound frequency and amplitude measurement / analysis through recording the audio using a microphone of your Android phone. It can give you a visual representation of many ultrasounds using a sampling rat.. The Sound Frequency Analyzer App is Android App created for real time sound measurement while performing a comprehensive analysis of the sound frequencies and amplitudes recorded. Now you can stop data collection when the start of the fading signal reaches the end of the FFT buffer. Figure 1. A fast and fluid spectrum analyzer that makes listening music more enjoyable. It can be used to analyze the characteristics for the sound/noise source.Features:# Measurement functionMain : Sound level measurement (real-time display)- Sound level measurement (dB): Leq (equivalent noise level), Lmin (minimum value), Lmax (maximum value), Lavg (time average equivalent noise level)- Frequency weighting correction characteristics : A (for noise level meter), C (for sound level measurement), Z (no correction)- Time weighting characteristics : Fast = 0.125 sec, Slow = 1.0 secPower Spectrum (P.S.) The calculation is not done for the extreme bins or if the adjacent bin is zero.• Calculation of the amplitude (in the list of peaks) using neighboring bins (to compensate for spectral leakage and use of the window). Free Sound Analyzer For iPhone Soundbeam helps you see what everyday sounds look like and visualizes sounds you can’t even hear! Must keep iPhone unlocked to use-- no good. When the sound is almost inaudible, it is necessary to find the amplitude for the frequency of 1000 Hz on the spectrum (FFT size: 16384). The amplitude of the waveform can be changed in the sound wave mode. This app is available only on the App Store for iPhone. There are buttons for quick loading and comparing saved files.• Dark theme.• List of frequency peaks. (OctVal)- Power spectrum display function at the time of occurrence of Lmax. The application is designed for analysis of a sound spectrum in real time (with a microphone). Sound Analyzer App lets you use your smartphone as a Sound Level Meter (SLM) and a Real time Audio Analyzer (RTA).
