Sound Command Records

A sound command record describes a sound command that you send to a sound channel using the SndDoCommand or SndDoImmediate function. The SndCommand data type defines a sound command record.

TYPE SndCommand =
PACKED RECORD
    cmd:            Integer;        {command number}
    param1:         Integer;        {first parameter}
    param2:         LongInt;        {second parameter}
END;

cmd

The number of the sound command you wish to execute.

param1

The first parameter of the sound command.

param2

The second parameter of the sound command.

The meaning of the param1 and param2 fields depends on the particular sound command being issued. See "Sound Command Numbers" for a description of the sound commands your application can use.
