#X text 14 355 This patch introduces the "tabread4~" object \, which
reads audio samples out of a floating-point array \, often called a
"sample table." The input is the index of the sample to read \, counting
from zero. The output is calculated using 4-point cubic interpolation
\, which is adequate for most purposes. Because of the interpolation
scheme \, tabread4~'s input cannot be less than one or greater than
the table length minus two.;
#X text 17 539 Fanatics take note: if you want really high-fidelity
sampling \, use a high-quality resampling program to up-sample your
soundfile to 88200 to drastically reduce interpolation error.;
