Oscilloscopes are electronic devices that display electrical signals as a two-dimensional graph. They are commonly used in science and engineering fields to measure and analyze signals such as sound waves, voltage, and current. In music production, oscilloscopes are used to assist in dynamics processing and sound synthesis.
An oscilloscope uses a two-axis graph to give a visual representation of a waveform over time, with the horizontal axis representing time and the vertical axis representing the amplitude. This allows music producers to see the shape of a sound wave and make adjustments to the sound accordingly. For example, an oscilloscope can be used to identify and remove unwanted noise or distortion in a recording.
In addition to assisting with sound processing, oscilloscopes can also be used to create visual art from sound waves. By playing sounds into an oscilloscope, the device can be made to display shapes and patterns that correspond to the sound. This technique, known as oscilloscope music, has been used by artists to create unique and visually stunning performances.

A sine wave is a smooth, continuous waveform, while a square wave has a more abrupt change in amplitude. A sawtooth wave has a gradual increase in amplitude followed by a sudden drop.
Amplitude
The amplitude of the waveform represents the loudness of the sound. The higher the amplitude, the louder the sound. The amplitude is measured in volts. The oscilloscope display shows the voltage of the signal over time.
Frequency
The frequency of the waveform represents the pitch of the sound. The frequency is measured in Hertz (Hz). The oscilloscope display shows the waveform over a period, or cycle, of the sound wave. The period is the time it takes for the wave to complete one cycle.
Transients
Transients are sudden changes in the waveform. They can be caused by a sudden increase or decrease in amplitude or frequency. Transients are often seen as spikes on the oscilloscope display. The tail of the transient can be seen as the waveform returns to its original shape.
Rising Edge
The rising edge of the waveform is the point where the waveform starts to increase in amplitude. The falling edge is the point where the waveform starts to decrease in amplitude. The time between the rising and falling edges is called the period.
an oscilloscope is a powerful tool for analyzing sound waves in music. It allows you to see the waveform, amplitude, frequency, transients, rising edge, and falling edge of the sound wave.
