Measuring Center 2.54 APK
In modern world tablet PCs or smartphones are playing greater rolein our lives. Devices, comparable in power with personal computers,gained a big part of the consumer market, supplanting PCs. Forgeneral consumer mobile devices completely replaced thefunctionality of PC, but specific tasks are still mostly solvedusing computers. It mostly happens because of the lack of necessarysoftware. Our company goes with the times and offers its customersthe possibility of using mobile devices for sound measuring andanalysing. We have developed an application for spectral analysisof sound for Android. The application Measuring Center for Androidis simplified version of the program for PC, but it still has itsreach functionality. The interface of the program is intuitive andeasy to use. It supports both the wired Spl-Lab devices (USB BASSMeter, USB RTA Meter, etc.) and wireless devices, such as WirelessBass Meter.

SPL Meter 1.03 APK
Sound Pressure Level Meter. This app uses the microphone to detectsound and convert it into an SPL value. FOR INDICATION ONLY.Results depend on your device and its hardware. The range betweenthe noise floor and saturation may be only 20 dB on the worstdevices, but could exceed 100 dB on the best devices. Features ofthis SPL meter include: Analogue Dial with Max and Minindicators.Weighting – A, C or None . (A weighting filters the highand low frequencies according to how the ear perceives soundloudness). Results are in dB, dBA or dBC depending onweighting.Averaging of SPL, Clear and Pause buttons.Octaves andthird octaves - Frequency spectrum of the sound.Graph – Shows thetime depedence of the sound.Autoscale or manual (pinch & pan)Y-Axis.Relative button – if looking for differences, tapping RELwill remove the current averaged value from the reading.Calibrateoption – If you have a calibrated SPL meter or known loudnesssource, you can use this option to calibrate the meter. (Howeverits still for Indication Only).More technical details can be foundon the website.
Function Generator 1.2 APK
Dual channel function / waveform / signal generator for the speaker/ headphone audio output.No Ads, No Permissions, No In AppPurchasing, No Limited Features. Full Version.Output is 16 bit foreach left and right channels and at 44.1kHz. Output will depend onyour device hardware. Some device hardware may may filter out theDC bias and low frequency signals. At high frequencies, thewaveforms will be distorted due to limited number of samples foreach waveform (for example at 4.41kHz, a sine waveform will beapproximated by only 10 points). Therefore this is forfun/educational use, for critical applications use a realcalibrated function generator.Left and Right audio channels can beassigned to either channel 1 or channel 2.Sine, Square &Triangular waveforms.Frequency range from 1 mHz up to 22kHz.Amplitude as percentage 0-100%.Set duty for square waveforms orskew triangular waveforms to get saw waveforms.Offset the phase ofwaveforms.Sweep frequency or amplitude (Single, Repeat & Bouncemodes).Amplitude Modulation (AM).Frequency Modulation (FM).Burstmode for a specific number of waveforms (1-10000).White noise &pink noise Generator.

Spectroid 1.1.1 APK
Spectroid is a real-time audio spectrum analyzer with reasonablefrequency resolution across the the entire frequency spectrum.💬 FAQ💬Q: Why are the dB values negative?A: Spectroid uses dBFS (FullScale) where 0 dB is the maximum power that the microphone canmeasure, so the decibel values are negative because the measuredpower is less than the maximum power.Q: Can I zoom in on thespectrum plot?A: Yes, do a two-finger pinch-to-zoom gesture.Q: Whyare there discontinuities/gaps in the spectrum plot andwaterfall?A: Spectroid uses multiple FFTs overlapped in frequencyin order to provide better frequency resolution at lowerfrequencies than a single FFT. The caveat of this method is variedimpulse response and minor discontinuities in frequency. The upsideis that it can efficiently produce a spectrum that better matchesthe frequency resolution of human audio perception. It's stillprobably not as good as your ears though!
