Spectrum Analyzer+ Audio FFT vs Spectrum Analyzer

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.

See sound in real time with Spectrum Analyzer: Audio RTA, a powerful audio analysis tool for visualizing frequencies, waveforms and spectral activity through your device’s microphone. Whether you are tuning speakers, examining music, testing audio equipment, identifying troublesome frequencies or simply exploring the sounds around you, the app gives you a clear and responsive view of your audio signal. REAL-TIME AUDIO SPECTRUM ANALYSIS View the frequency content of live sound as it happens. The spectrum analyzer separates the incoming audio into frequency components, making it easier to identify peaks, harmonics, resonance and changes across the sound spectrum. FFT FREQUENCY ANALYZER Use Fast Fourier Transform analysis to examine the frequencies present in music, speech, instruments, speakers and environmental sound. Follow frequency peaks and observe how the signal changes over time. LIVE SPECTROGRAM Turn sound into an easy-to-read visual frequency map. The spectrogram displays how frequency intensity develops over time, helping you recognize tones, harmonics, patterns and transient sounds. AUDIO WAVEFORM DISPLAY Watch the shape and amplitude of the microphone signal in real time. The waveform view provides a direct visual representation of changes in volume and signal behaviour. RTA FOR AUDIO TESTING Use your iPhone or iPad as a convenient real-time analyzer for: • Speaker and stereo testing • Room and acoustic checks • Music and instrument analysis • Identifying frequency peaks • Monitoring background noise • Examining voices and sound effects • Audio equipment testing • Learning about sound and frequencies UNDERSTAND THE SOUNDS AROUND YOU Spectrum Analyzer: Audio RTA helps reveal details that are difficult to recognize by listening alone. Observe low, mid and high frequencies, compare different sounds and discover how every audio source creates its own spectral pattern. DESIGNED FOR QUICK, CLEAR ANALYSIS The responsive interface makes it easy to move between audio analysis views and focus on the information you need. Use it for technical checks, music production, education, acoustic experiments or everyday sound exploration. KEY FEATURES • Real-time audio spectrum analyzer • FFT frequency analysis • Live spectrogram visualization • Audio waveform display • Frequency and amplitude monitoring • Microphone-based sound analysis • Clear visual representation of audio signals • Support for both portrait and landscape use • Useful for speakers, music, voices and environmental noise From simple sound experiments to detailed frequency inspection, Spectrum Analyzer: Audio RTA puts a capable audio visualization tool in your pocket. Download the app and start seeing the frequencies hidden inside every sound.
