Oscilloscope vs SoundScope

"I use this for analog, and audio measurements. Attach an Apple USB adapter and a $40 stereo A-D converter available online, and my iPad is like a $300 O'Scope." -thymeout- Oscilloscope app is great for analyzing audio range signals, or learning oscilloscope measurement basics. The interface includes many standard oscilloscope controls, such as: triggering, time and voltage per division, signal measurement cursors, and more. The app incorporates a signal (function) generator capable of generating sine, square, triangle, and sawtooth waveforms of up to 22 KHz. Calibration to an external reference signal is supported, guaranteeing the accuracy of measurements. Input can be acquired via the built-in microphone or an external mic/probe connected to the headset connector. For best results, use an external audio interface connected to your device dock. This allows for standard audio equipment to be connected, as well as for dual channel input. Oscilloscope probes also be connected (using a BNC connector). When feeding external signals via probes, you should take care not to exceed 1V AC voltage. Currently iDevices support only AC input.

See your sound. SoundScope turns your iPhone and iPad into a complete audio analysis instrument — spectrum, loudness, stereo field, and dynamics, measured with broadcast-grade precision and rendered in a stunning brushed-metal interface. Whether you're mixing, mastering, running live sound, tuning a room, or you simply love watching music breathe, SoundScope shows you what your ears alone can't catch — and tells you how to fix it. — FOUR WAYS TO SEE YOUR SOUND — • SPECTRUM — high-resolution real-time analyzer with bars or silky line mode, animated peak hold, 20 to 120 bands, logarithmic or linear scaling • SPECTROGRAM — scrolling waterfall with a gorgeous inferno heat map, 20 Hz to 20 kHz • RADIAL BLOOM — an ambient circular analyzer with a core that pulses to the beat • RIBBON TUNNEL — a mirrored neon ribbon that turns your desk into mission control — BROADCAST-GRADE LOUDNESS — A full ITU-R BS.1770 loudness suite: Momentary, Short-term, and gated Integrated LUFS, Loudness Range (LRA), intersample True Peak (dBTP), and a DR dynamics score. Know exactly how loud you are before you upload — not after. — A MIX ENGINEER IN YOUR POCKET — The built-in diagnostics engine listens with you and speaks plain English: clipping alerts, loudness-war warnings, crushed dynamics, mono sub-bass cancellation, and frequency-balance issues — all judged against genre profiles for EDM, Hip-Hop, Rock, Classical, Acoustic, and Podcast. It even tells you how far streaming platforms like Spotify and YouTube will turn your track down. — READ THE STEREO FIELD — Stereo VU meters with peak hold, a live stereo-image scope, Mid/Side spectra, and a phase-correlation meter. Per-band RMS from sub to air, plus a mono-compatibility strip that shows exactly where your mix collapses in mono. — SURGICAL CONTROL — FFT sizes from 64 to 131,072 with TRANS / BAL / MASTR presets, overlap up to 93.75%, HOLD to freeze and inspect any moment, and input sensitivity from 0.1x to 4x. — ANY SOUND. ZERO SETUP. — Point it at your studio monitors, a live PA, an instrument, or a track playing back — through the built-in mic or any connected audio interface. Rotate to portrait for full metering, landscape for the analyzer. — DESIGNED TO BE LIVED IN — A luxurious brushed-metal instrument with tactile controls, haptic feedback, and eight accent themes — including a live per-frequency Spectrum rainbow. Full dark-mode and Reduce Motion support. — PERFECT FOR — • Studio engineers, producers, and mastering • Live sound and FOH engineers • Musicians, vocalists, and podcasters • Acousticians, installers, and educators • Anyone serious about sound No subscriptions. No accounts. No sign-in. No telemetry. Everything runs on-device and offline, with Apple-native engineering that stays silky-smooth on iPhone and iPad. Stop guessing. Start seeing. Download SoundScope and hear with your eyes.
