Mega Converter vs Spectrum Analyzer+ Audio FFT

Every converter a professional reaches for, in one app. 36 categories, 198 units and 15 specialist tools that ordinary converter apps skip. Built for people who convert for a living: trades, engineers, designers, video editors, developers and cooks. And there is not a single ad in it. WHAT YOU CAN CONVERT • Convert length, weight, temperature, volume, area, speed and time • Work in pressure, torque, power, force, energy, density, flow and fuel economy • Check live exchange rates for 30 currencies, cached so they keep working offline • Match wire sizes with AWG to millimetre tables built for the job site • Run SMPTE timecode at every frame rate, drop frame handled correctly • Turn cups into grams for 25 real ingredients, with oven temperatures included • Compare time zones city by city and paste the result into a meeting invite • Convert colours across HEX, RGB, HSL and CMYK with contrast checks • Switch between binary, octal, decimal and hex with a 32 bit view • Calculate percentages, tips, discounts, date gaps and download times • Convert Roman numerals, paper sizes, Unix timestamps and more MADE FOR ACCURACY Conversion factors follow SI and NIST definitions, exact where an exact definition exists. Numbers stay monospaced while you type, results show sensible precision, and every tool works with no signal. SHARE THE ANSWER Every tool shares a clean text summary, so the person on the other end gets the conversion, the working and the source in one message. MEGACONVERT PRO One subscription unlocks every category and tool, billed monthly or yearly. Cancel any time in your Apple Account settings. The whole catalogue is free to browse before you decide.

Spectrum Analyzer+ Audio FFT shows the live frequency spectrum of any sound your iPhone microphone hears, then lets you capture a 5-second average and read the result: the strongest frequency in Hz, the top components and where the energy sits. ▶ See the spectrum live • 32 bands from 20 Hz to 20 kHz, computed with a 2048-point FFT • Four views: Bars with peak hold, Line, Waterfall and Spectrogram • Peak frequency and peak level update as you listen • Min / Max traces in the Bars view, tap a bar for a cursor readout, freeze the display to study it • Adjustable dB range from 30 to 120 dB ▶ Capture 5 seconds, get an answer Tap Capture 5 s under the graph and hold the sound steady. The app power-averages the spectrum over five seconds and shows a result card: • Strongest component in Hz, with the musical note and cents in Voice mode • Up to three top components with their levels • Share of the detected energy in the low, mid and high part of the selected range • Strongest band level and the FFT resolution of the measurement If the sound is too quiet in that range, the card says so instead of inventing a peak. ▶ Compare before and after Save a capture as a reference (up to 10). Make a change — move a speaker, add treatment, adjust a machine — capture again in the same mode and the card shows the average band-level difference in dB. References can also be overlaid on the live spectrum. ▶ Pick the job • Voice: 80–4000 Hz, shows the note of the strongest pitch • Machine: 20–2000 Hz, looks for 50/60 Hz mains hum and its harmonics • Room: 20–500 Hz, the low end where room modes build up ▶ Export and share • Export a CSV of the live spectrum or of a 5-second capture • Share a short text summary of a capture ▶ Extras • Calibration offset from −20 to +20 dB in 0.5 dB steps to line up with a reference meter • Pink noise generator, unlocked for 24 hours by watching a short ad • Interface in 30 languages ▶ Good to know Levels are relative to the microphone's full scale (dBFS). A phone microphone is not a certified sound level meter, so use the numbers to find frequencies and compare changes, not for compliance measurements. Audio is analysed in memory while you listen and is not saved as a recording. For musicians checking a tone, home studio and hi-fi owners chasing a boomy note, and anyone tracking down a hum from a fridge, fan or transformer.
