Sound Spectrum Pro vs SoundScope

RTA (Real-Time Analyzer), FFT (amplitude display driven by Fast Fourier Transform), calibration, signal generators... Everything is included, bundled in a friendly interface with many on-screen controls and smooth real-time display. == Features == + FFT (amplitude) and RTA (octave, 1/3 octave, ... down to 1/24 octave). + Sound pressure level dBA, dBC, and dBZ. + Noise Criterion and Noise Rating in octave RTA. + Equivalent continuous sound level LAeq, LCeq, LZeq, LAeq15, LAeq60. + Impulse response and RT60 measurement. + Large font SPL + LEQ meter. + THD+N Total Harmonic Distortion plus Noise + Lightning-fast FFT with size from 16k to 1M, providing frequency resolution of 0.05Hz directly and 0.01Hz with downsampling. + Sample rate of 48kHz, if supported by the device. + Many window functions to choose from. + Peak and valley hold with adjustable decay. + Highest peak display + Adjustable exponential smoothing. + Easy pan (drag) and zoom (pinch). + Measurement cursors, also used for setting frequency of signal generators. + File load/save and full calibration capability, for accurate SPL readings. + Signal generators: tone, white noise, white sweep, pink noise, pink sweep, pink octave, pink 1/3 octave. + Synchronous measurement mode (including frequency sweep) for clean and fast spectrum analysis. + Loopback mode to try out signal generators and window functions. + No ads!

See what you hear. SoundScope turns your iPhone and iPad into a professional audio analyzer: a real-time spectrum analyzer, a broadcast-standard loudness meter and a mix assistant that tells you what to fix. All in one app. LOUDNESS, MEASURED PROPERLY • Momentary, short-term and integrated LUFS to ITU-R BS.1770 • True peak, loudness range (LRA), DR and PLR • Start, stop and reset a measurement whenever you need MIX DIAGNOSTICS • Clear alerts for clipping, true peak, streaming loudness, crushed dynamics and mono bass cancellation • Tonal balance checked against genre profiles: General, EDM, Hip-Hop, Classical, Rock, Acoustic and Podcast/Voice • See how far Spotify and YouTube will turn your track down, before you upload SPECTRUM ANALYZER • Real-time FFT from 20 Hz to 20 kHz with peak hold • Bar or line view, 20 to 120 bands, logarithmic or linear scale • FFT modes for transients, balance and mastering, with adjustable FFT size and overlap • Hold the spectrum to study a single moment FIVE FULL-SCREEN VISUALIZERS Turn your phone sideways for Spectrum Bars, Spectrum Line, Radial Bloom, Spectrogram and Ribbon Tunnel. Double-tap to switch views. STUDIO METERING • Dual VU meters with peak hold • Stereo image, phase correlation and left/right/mid/side spectra • Band RMS and mono compatibility for every band MADE TO BE USED • Eight color themes, including the per-frequency Spectrum rainbow. Swipe to change. • Built-in microphone or a connected audio interface, with adjustable sensitivity • A brushed-metal interface built for one-handed use PRIVATE BY DESIGN Everything runs on your device. No subscription, no account, no tracking and no internet connection needed. One purchase covers iPhone and iPad.
