Spectrogram (New Version 16.0) is a calibrated, dual channel audio spectrum analyzer for Windows that can provide either a scrolling time-frequency display or a spectrum analyzer scope display in real time for any sound source connected to your sound card. Spectrogram allows unlimited recording and playback of the sounds from the spectrum display and can provide high resolution spectrum analysis with a wide choice of frequency bands and frequency resolutions and either linear or logarithmic frequency scales. Spectrogram also includes an Ultrasound Display designed for use with ultrasound detectors for analysis of high-frequency vocalizations of bats, and communication signals by insects, rodents or other animals. Version 16 replaces the older freeware versions of the software relied upon by the majority of Spectrogram users. The download at left is a self-extracting setup program that will install Spectrogram on a single computer.
