"IBM" is a sonification of IBM's stock dating back to 1961, specifically three daily data points: opening price per share, closing price per share, and volume of shares. The sonification algorithm averages the prices to determine the duration and interval of two low-frequency sine tones. The interval between them is determined by the difference betweeen the opening and closing price. The volume of shares determines the gain of a high-frequency tone.
