VST-осциллоскоп с удобной линейкой, и масштабированием.

The s(M)exoscope also contains a tool that can be used to analyze the waveform currently in the display. Based on where you place a marker, the tool analyzes the x and y dimensions of the waveform to calculate the following:

• Selection amplitude (linear)
• Selection amplitude (decibels)
• Selection length (in samples)
• Selection length (in seconds)
• Selection length (in milliseconds)
• Selection frequency (assuming that the selection is one cycle in length)
