Comments

A table in OSW is a collection of ordered floating-point numbers, which can be looked up either as elements in a traditional integer-indexed array, or as values in a floating-point function evenly spaced over the range between min and max.

OSW includes several built-in tables:

/sine: the function sin2px evaluated between 0 and 1 (i.e., one period of a sine function).
/cosine: the function cos2px evaluated between 0 and 1.
/exp: the function e^-px evaluated between 0 and 1.
/sinc: the “sinc” function sin(x)/x evaluated between -2p and 2p. Similar to previous tables, this period is normalized between 0 and 1.

All of these tables have 1024 entries and are normalized to floating-point indices between 0 and 1.

Use the Table transform to define additional tables in your application. Initially, a table contains all zeroes when you define it. You can manually edit the table by double-clicking the transform. This brings up a dialog box that lets you "draw" new table values using either a line or a freehand tool:

You can also modify tables algorithmically using the table::Peek and table::Poke transforms, or store blocks of samples (e.g., from audio input) into a table using table::Record.
