The SGSetSoundInputRate function allows the sequence grabber component to set the rate at which your sound channel obtains its sound data.

pascal ComponentResult SGSetSoundInputRate (SGChannel c,
                                             Fixed rate);

c

Identifies the channel connection for this operation.

rate

If your sound channel cannot support the specified rate, use the closest available rate that you can support. If this parameter is set to 0, use your default rate.
