Conclusion
While we removed the
cough, we lost quality in the recorded sound. Using a different
alogorithm, but the same Bandwidth Enhancement analysis, we could
improve on our results.
Possible
improvements:
- Increase
the number of harmonics used to calculate the closeness of partials
in the "outCrowd" to the partials in the "inCrowd"
- Create
templates of different types of noise: claps, coughs, etc.
- After
the partials have been created. Perform a match filter
operation on them to see how close they are to a given "noise
template" if they differ greatly from the "noise
template" add and are relatively close to a harmonic
of a dominating partial (one of those in the "inCrowd"
then add them to the "inCrowd")
