1. An infant swing comprising:a support; a seat, said seat pivotally coupled to said support; a drive mechanism, said drive mechanism coupled to said seat and adapted to impart motion to said seat for a first time period; an audio input detector; means for comparing audio input detected by said audio input detector relative to a predetermined amplitude level; and means for controlling said drive mechanism based upon whether said audio input exceeds said predetermined amplitude level for an entire duration of a predetermined second time period. 2. The infant swing of claim 1 wherein said audio input detector includes a sensor.3. The infant swing of claim 1 wherein said drive mechanism includes a motor and said means for controlling includes a processor that controls said motor.4. The infant swing of claim 1 further comprising:means for determining the back EMF of said motor, said processor analyzing said back EMF to determine a load on said motor. 5. The infant swing of claim 4 wherein said processor causes said motor to impart motion to said seat for a fourth time period if said audio input exceeds said predetermined amplitude level.6. The infant swing of claim 5 wherein said means for controlling utilizes pulse-width modulation to control said motor.7. The infant swing of claim 1 wherein said second time period occurs after a third time period has elapsed.8. An infant swing comprising:a frame; a seat, said seat coupled to said frame; a drive mechanism coupled to said seat, said drive mechanism adapted to impart motion to said seat for a first time period; a sensor, said sensor adapted to detect an audio input during a predetermined second time period; and a processor, said processor connected to said drive mechanism and said sensor, said processor adapted to cause said drive mechanism to impart motion to said seat after said first time period in response to the detection of said audio input by said sensor for an entire duration of said predetermined second time period. 9. The infant swing of claim 8 wherein said first time period is approximately equal to a sum of said second time period and said third time period.10. The infant swing of claim 8 wherein said drive mechanism includes a motor, said processor determining a load on said motor and controlling said motor based on said load.11. The infant swing of claim 8 wherein said predetermined second time period occurs after a third time period has elapsed.
