Hidden Hidden Hidden Hidden


SoundScope is a third generation speech and sound analysis product line that represents a breakthrough in ease-of-use and advanced features. Record a sound, perform analysis, extract key values, and compute statistics all with a few clicks of the mouse. Scroll through data, adjust the scale or display range, and even change the parameters for sound analysis computations. SoundScope offers unprecedented flexibility that you can begin using today.

SoundScope is compatible with OS 8, 9, and 10.x (in Classic 9.x Mode); yet does NOT run under OS ≥ 10 in native mode.


  • Record, view, analyze, play, store & print sound waveforms.
  • See spectrograms in full color.
  • View fundamental frequency (Fo), jitter (pitch pertubation), shimmer (amplitude pertubation), frequency spectra (FFT), linear predictive coding (LPC), and much more.
  • Compute statistics such as percent voiced, percent unvoiced and percent silent.
  • Design your own instrument screen, no programming required.
  • Customize menus and displays.
  • Cut, Copy & Paste between SoundScope and other applications.
  • Record and playback up to maximum CPU memory (e.g. record for 100 seconds at 22kSamples/sec with 4.5 MB of free memory).
  • Enter notes and observations into the integrated text editor.

2 Channel Analyzer

This instrument features dual time waveform windows for viewing and comparing two sound waveforms simultaneously, dual analysis windows which can be used to display and compare spectrograms, Fo and other pertubation measurements of the two sound waveforms, dual snapshot windows for displaying and comparing FFT''s, LPC, and expanded time segments of the two sound waveforms, and a journal for keeping notes.

2 Channel Editor

This instrument shows a detailed view of two waveforms.
