Audio RTA vs Microtonal Interval Eartrainer

See the live sound spectrum, find frequency peaks and test your speakers with a practical audio toolkit on your phone. For musicians, sound technicians and installers working with PA systems, studios, instruments and car audio. Use the microphone spectrum as a visual aid when checking sound; the app does not automatically equalize your system. Free basic tools: • Real-time microphone RTA/FFT spectrum • Approximate dB level meter • Frequency generator from 20 Hz to 20 kHz • Subwoofer and stereo channel tests • White noise for general testing Audio Tools Pro is a one-time purchase for lifetime access to advanced tools: waterfall/spectrogram, third-octave bands, manual dB offset, PNG/CSV exports, pink noise and advanced waveforms and sweeps. Access stays linked to your store account. Measurements depend on your device microphone and hardware. Manual dB offset aligns readings to a reference meter; it does not provide certified calibration. Use low volume to protect hearing and equipment. The app does not replace a certified sound-level meter or measure calibrated loudspeaker frequency response. Audio analysis runs on your device; purchases require a connection.

Enjoying new exotic songs, but have no idea what their unfamiliar harmonies are doing? With a little training, you can recognize and reproduce crazy harmonies yourself! TRAIN YOUR EAR, TRAIN YOUR VOICE Interval Ear Trainer turns ratios from JI (just intonation) and EDO (equal divisions of the octave) into focused, colorful practice sessions. Choose prime limits from 5-limit (traditional Western harmony) through 7-limit, 11-limit, 13-limit, and higher. Then, identify the intervals you hear. Targeted practice brings back troublesome intervals with nearby contrasts and familiar landmarks. Once you've trained your ear, train your voice with Hum mode, and let the app detect how close you are to singing intervals. Or, get started on recognizing chords, scales, and even scale progressions! EXPLORE THE SPECTRUM Turn off the pressure and enter a free spectrum mode, where you can practice your chosen intonation at will. A live display shows where your voice lands and highlights nearby intervals. Turn real practice history into polished accomplishment cards and challenge your friends to see how they do.
