About Spectran
Spectran performs real-time or deferred spectral analysis and waterfall visualization of audio signals. A waterfall display shows how signal energy changes across frequencies over time, helping users identify tones and patterns. The program also provides real-time audio filtering, including band-pass, band-reject, denoising, and CW peaking functions. These features support analysis and processing of audio or radio signals, with both live and recorded input workflows. The supplied information does not specify supported audio devices, frequency ranges, or file formats. Its role is combining spectrum inspection with several real-time filters for signal analysis. The waterfall view is useful for inspecting changes in a signal over time.
