## Description

Spectrum turns your phone into a modern real-time audio analyzer - the clean, fast tool that older spectrum apps never gave you.

See sound the moment it happens: a live FFT frequency spectrum and a scrolling spectrogram (waterfall), with automatic peak detection and the matching musical note. Built for a phone screen, with a beautiful dark and light theme - not a cramped desktop port.

WHY SPECTRUM
• Modern, readable interface - designed for touch, dark & light themes
• Save your measurements and revisit them anytime (most analyzers forget everything the moment you close them)
• Export the spectrogram as a high-resolution image, or your data as CSV
• Works on both iPhone and iPad
• Real peak frequency + musical note readout, in cents

FEATURES
• Real-time FFT spectrum, log or linear frequency axis
• Spectrogram (waterfall) view
• Tap the chart for a frequency cursor with dB and musical note
• Peak hold and peak-frequency tracking
• Musical note detection (A4 = 440 Hz)
• A-weighting for perceived loudness
• Adjustable FFT size (2048 / 4096 / 8192)
• Save, name and organize measurements
• Image & CSV export
• 8 languages

SPECTRUM PRO - one-time purchase, no subscription
• 1/3 octave RTA view with per-band peak hold - the classic real-time analyzer used for live sound and room tuning
• Tone generator: sine tones, 20 Hz-20 kHz logarithmic sweep, white & pink noise for testing speakers and room acoustics
• Peak list: the strongest peaks with harmonics tagged
• Up to 4 frequency markers on the chart
• Calibration offset (±20 dB) to match a reference meter
• Extra-high resolution 16384 FFT
• High-resolution image export and no ads, forever

Everything is processed on your device - no audio is ever uploaded. Microphone access is the only permission needed.

Perfect for musicians, audio engineers, students, DIY speaker builders, hum & noise hunters, and anyone curious about the sounds around them.
