v7 v8 73 73 int GetTempo(float freq); 74 74 }}} 75 This function receive has aparameter the frequency the object desires to operate. As the environment (ALOE) is the only who knows the execution interval associated to the process, a simply operation will be done to calculate the number of samples to be generated at that precise moment. The amount of samples that the object needs at its input will depend on the algorithm, more precisely, in the rate relation between the input and output frequency. Anyway, the object will wait until all the data it needs is available. Note that this could lead to time violations if frequency relations between collateral objects are not defined with caution.75 This function receive as parameter the frequency the object desires to operate.
