Oscilloscope is a compact application that allows you to visualize the audio input waveform by using your sound card. It is designed to emulate a standard oscilloscope in order to analyze a sound signal in real time.
In order to use the program you need to connect the sound measurement equipment to your sound card. You can use a simple microphone or other devices that produce the sound signal that you want to analyze.
The main window of the application displays the graphical representation of the sound signal and allows you to configure the gain, delay and sweep parameters. You can use multiple graph types in order to study the real time spectra.
The captured data can be saved to a DAT file in order to compare different signals or different intervals for the same sound input. You can also copy the waveform data to the clipboard in order to use it in other programs.
The application includes a spectrum analyzer that displays the amplitude spectrum for the sound received through the channels. When working in dual trace mode, the user can also use the phase adjustment feature in order to adjust the data before phase shift measurements.
Although the interface is clean and provides access to all the controls, this app is designed for the users with previous experience in sound signal and spectra analysis. If you want to understand the role of certain controls, the included documentation provides you with a general description.
Oscilloscope requires no installation which allows you to run it from a removable device when you need to visualize or analyze a sound signal.
