About GSound RTA
GSound RTA is a sound analyzer for sound engineers and karaoke system owners. FEEDBACK FINDER Raise the mic volume slowly and the app catches the frequency that starts to ring, then tells you what to do: "31-band EQ: pull the 2.5k slider down 6 dB. PEQ: 2480 Hz, Q 8–10, cut 6 dB". Every feedback frequency is listed so you can EQ them one by one. It tells feedback apart from fans, mains hum, speech and sung notes, so background noise rarely triggers false alarms. MEASUREMENT • RTA in 1/1, 1/3 (matches a 31-band EQ), 1/6 and 1/12 octave bands with peak hold. • High-resolution FFT up to 32768 points, 4 windows, frequency cursor. • Waterfall (spectrogram): feedback shows as a bright horizontal line. • dB meter with A / C / Z weighting, LAeq, LAmax, clip warning. dB SPL calibration against a reference meter. • Full-screen graphs and freeze to read values. SIGNAL GENERATOR Pink noise, white noise and sine 20 Hz – 20 kHz for system EQ, rattle hunting and subwoofer checks. MICROPHONE Uses the iOS Measurement mode: no automatic gain, noise reduction or voice filtering. Choose the bottom, front or back iPhone mic. Works with USB measurement mics (miniDSP UMIK-1…) via USB-C or a Lightning to USB 3 camera adapter. No ads, no account, no internet needed. Audio is processed on the phone only and never recorded. Vietnamese and English.
