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.
