Digital Delay   

The effects achieved by the use of tape delay can be simulated using digital techniques with higher fidelity and lower noise. The  range of time delays (from milliseconds to seconds) in digital delays permit a wide range of processes: from flanging (0.1 - 20 ms.) to doubling and/or chorus (15 - 35 ms.) to echo (reverb-like) (50 - 100 ms.) to discrete delays (80 up). 
 
Sound Examples:
 
  drip    drip delayed 
this drip was delayed by 0.35 seconds over a period of 4.5 seconds.
