 "description": "The spectrogram with memory.\n\nSpectraHold turns microphone input into a 3D spectrogram. Watch frequencies in real time, freeze the view, and explore up to 120 seconds of visual history to inspect a detail you just heard.\n\nFREEZE AND EXPLORE\nTap the graph to inspect a frequency. Zoom and browse the history, then return to live analysis whenever you want.\n\nADJUST THE VIEW\nChoose a visible window from 1 to 20 seconds, color palettes, and automatic or manual visual gain from −40 to +40 dB. Visual gain changes the graph without changing microphone gain.\n\nFEATURES\n• Real-time 3D spectrogram from 20 Hz to 20 kHz.\n• Adjustable history from 20 to 120 seconds.\n• Frequency inspection, zoom, and history navigation.\n• Up to two estimated peaks per region: bass, midrange, and treble. Detection does not confirm resonance.\n• Background capture and capture with the screen locked, while permitted by the system.\n• Compatible with iPhone and iPad.\n\nAudio is processed on your device. History stays in memory; no audio file is saved or uploaded. Closing the app or a system interruption may stop capture.\n\nTRIAL AND PURCHASE\nDownload for free. Activate a free 7-day trial to access all features. After the trial, analysis stops until you purchase full access. The unlock is a one-time purchase, with no subscription or automatic charge. The local price is shown before you confirm the purchase. You can restore purchases.\n\nSpectraHold is a visual analysis tool. It does not apply equalization, automatically eliminate feedback, or replace a calibrated sound pressure level meter. Estimates depend on the microphone, device, and recording conditions.",
