Options 1/1, 1/three & 1/6 octave RTA modes, Leq (wideband, Octave, variable length), RT60 (wideband, Octave), Spectrogram, Peak frequency, Quick, Medium & Gradual filters, Flat & A/C Weighting and movie trade X Curve, Averaging, SPL Chart Recorder, Noise Standards, White/Pink Noise, Sine, Sq., Triangle, Sweep, Ramp and Impulse indicators & loudspeaker polarity checker, L/R choose. RTA Retailer & Load, Hann home windows, "Maintain Display screen On", pinch to zoom, scroll to heart.
Unique ISO 1/three Octave Calibration – right in your cellphone’s microphone response. Octave calibration discs are moved up or all the way down to receive a flat response, and match the general SPL to that of an exterior meter. Save/Restore of Cal information (Dayton Audio iMM-6 additionally supported).
Use: house theater, audio engineer, automobile audio, and so forth
AudioTool FFTs units of samples recorded on the microphone. Aliasing lowered by Hann windowing. SPL calculated in realtime. Spectra could also be saved as information on the SD card, then loaded and displayed with the stay spectrum. The "Retailer" button shops the present stay spectrum – "Load" reveals an inventory of saved spectra to pick out.
To cover the buttons, faucet the display screen. To revive them, faucet once more. To zoom the dimensions, pinch the display screen. To maneuver the dimensions, drag it up or down (left or proper).
The deciBel meter makes use of IIR filters and exponential averaging to calculate Flat, A and C weighted response at speeds of Quick, Medium and Gradual speeds.
A pair of cursors could be proven on the RTA and Chart Recorder shows: every could be moved to any place, and can show the SPL & time/frequency values there. Initially, each cursors are positioned mid-screen – merely drag them to a brand new place with the fingertip. The cursors could be turned on and off within the Menu.
The loudspeaker polarity checker can be utilized to verify whether or not a loudspeaker is wired in section: join the AudioTool output to the speaker underneath check, choose "Polarity" from the sign generator display screen, then return to the RTA display screen. If the speaker is out of section (polarity reversed) AudioTool will present "Pol —", in any other case "Pol +++" if the speaker is in section.
The Noise Standards (accessible from the Menu) operate reveals a set of NC contours overlaid on the 1/1 Octave RTA show and the calculated actual time present NC worth can be proven.
The Chart Recorder reveals a shifting hint of the SPL measurements over the previous couple of minutes.
RT60 measurements could be made by beginning the RT60 part utilizing the "RT60" button, after which utilizing a loud clap (or related) to set off the measurement. RT60 will also be used with Pink Noise from the AudioTool generator. RT60 occasions measure how a lot reverberation or echo there may be in a room or auditorium.
The Sign Generator generates White and Pink Noise, Sine, Sq., Triangle and Ramp waves, Sine Wave Sweeps and Impulses. The generator makes use of a number of cycled buffers, refreshed randomly so guaranteeing actually random White/Pink noise. Pink Noise algorithm makes use of Kemmet’s technique to regulate White into Pink.
The frequency accuracy of the generated periodic indicators is often round 1%. Sine wave constancy is nice all through a lot of the audio vary. Different indicators’ main and trailing edges present ringing and lowering frequency response artifacts within the higher ranges, relying on the Android used.
