Sci vs Live Spectrum Analyzer

一、Basic Description 1、This software is mainly used in the digital experiment of primary and middle schools, including physical, chemical and biological experiments. 2、To work properly, the software needs to be used with sensors and bluetooth transmitter modules (sensors are connected to bluetooth launch modules). The sensor data is sent to the receiving end of the iPad or iPhone via a connected bluetooth module. 3、The software operates on portable mobile devices such as iphone or ipad, which has bluetooth low power consumption of BLE 4.0. The software can actively detect and connect bluetooth devices, real-time data collection, analytical sensor data, digital、graphic display digital and graphic display, with functions such as plug and play, automatic recognition ( sensor ), parallel acquisition, combination drawing, free coordinate, line analysis ( fitting, integral, etc. ), table record, add variables, formula, table data drawing, etc. 4、The overall design of this software adopts the Qt5.12.0 technical framework and Objective-C mixing method. 二、Use Instructions 1、Access the Bluetooth transmitter module to the sensor , turn on the power on the Bluetooth transmitter module, and then the indicator light is on. 2、Start the software on the ipad or iphone. 3、The software initial startup interface is QR code scanning interface. The ID information of the device can be automatically scanned and displayed by a QR code that is pasted on the target bluetooth module in the various bluetooth devices that are enabled, which can support scanning of 4 bluetooth modules ( that is, up to 4 sensors at the same time ),after the scan is completed, click start experimental button start scanning, discovering, connecting bluetooth equipment, sensor data transmission, data display and analysis. For easy control, it is recommended that the software be installed on the device with a screen of 4.7 inches and above. Please ensure that the operating system version is iOS 11.0 or above.

Live Spectrum Analyzer is a real-time audio visualization tool for musicians, students, teachers, sound makers, and anyone who wants to see sound clearly. Use the microphone for live input, or import an audio file from Files to inspect how frequency, amplitude, pitch, and dynamics change over time. Switch between waveform, FFT, sonogram, spectrum bars, VU meter, pitch, octave bands, peak hold, envelope, waterfall, phase, Lissajous, and XY Scope views. Each mode is designed for quick visual reading while you listen, tune, practice, demonstrate acoustics, compare sounds, or check a recording. The app also provides practical analysis readouts, including RMS, peak level, decibels, detected pitch, strongest frequency peaks, spectral centroid, zero crossing rate, dynamic range, estimated BPM, beat strength, mel bands, chroma, noise floor, and clipping status. Results are intended as helpful visual references rather than certified measurement data. Key features: • Live microphone waveform and spectrum visualization • Import audio files for playback and local visual analysis • Waveform, FFT, sonogram, bars, VU, pitch, waterfall, phase, and scope modes • Adjustable gain, time window, FFT floor, sonogram brightness, contrast, and speed • Pitch reference, tolerance, microphone gain, and noise gate settings • Record audio locally, review saved recordings, and share or delete files • Capture visualization snapshots as PNG images • Local-first workflow with no account required Subscription and purchase information: The app offers a free experience and optional Pro access. Actual prices, trials, promotions, and availability are shown in the App Store. Privacy and data information: Your microphone input, imported audio, recordings, snapshots, and analysis results stay on your device by default. The app does not require an account and does not upload your media to a server operated by us.
