<title>Initialization</title>
<para>
<emphasis>idlt</emphasis> -- requested delay time in seconds. This can be as large as available memory will permit. The space required for n seconds of delay is 4n * <emphasis>sr</emphasis> bytes. It is allocated at the time the instrument is first initialized, and returned to the pool at the end of a score section.
</para>
<para>
<emphasis>iskip</emphasis> (optional, default=0) -- initial disposition of delay-loop data space (see <link linkend="reson"><citetitle>reson</citetitle></link>). The default value is 0.

<title>Performance</title>
<para>
<emphasis>delayr</emphasis> reads from an automatically established digital delay line, in which the signal retrieved has been resident for <emphasis>idlt</emphasis> seconds. This unit must be paired with and precede an accompanying <link linkend="delayw"><citetitle>delayw</citetitle></link> unit. Any other Csound statements can intervene.
