Spectrum Analyzer Software

/ Comments off

The spectrum analyzer software computes and displays the spectrum, power-density spectrum, and spectrogram for variety of signals and data types, including audio, biosignals, communication signals, speech, and streaming data. The user interface, features, and measurements are consistent with conventional hardware-based spectrum analyzers. Spectrum Analyzer is a music visualization tool. You can visualize sound coming from phone's microphone in variety of shapes and effects.
