Using map and filter, maximize a sound—if a sample’s value is greater than or equal to 0, make the sample value 32, 767, and if not, make it ?32, 768.

Question

Note: Since filter will only return elements that meet the method requirements, its necessary to have two methods: one to capture positive samples, and one to capture negative samples.

Answer 1

```
def extremify(sound):
map(maximize,filter(positiveSample, getSamples(sound)))
map(minimize,filter(negativeSample, getSamples(sound)))

def maximize(sample):
setSampleValue(sample, 32767)

def minimize(sample):
setSampleValue(sample, -32767)

def positiveSample(sample):
val = getSampleValue(sample)
if val>=0:
return 1
else:
return 0
def negativeSample(sample):
val = getSampleValue(sample)
if val<0:
return 1
else:
return 0
