Spectrum Analyzer: Audio RTA

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.
