Abnormal breath sounds like wheezes, crackles and stridor at times manifest similar morphologies and pathological features of lung airways obstruction. This may pose problems to proper diagnosis and evaluation of the underlying respiratory condition by human auscultation.

The TFTD algorithm computes important and distinctdoi:10.5120/ijais14-451265 fatcat:4upcoficafa7ticibqoe6jgdm4
