CSCI-128 Coding for Problem Solving
Question 1:
Complete the following function that take in input the sound and a percentage. The
percentage indicates how far into the sound to go before changing from increasing to
decreasing the volume.
def increaseAndDecrease(sound, percentage):
Question 2:
Complete the following function. The function should normalize the first second of the sound,
then slowly decrease the sound in steps of 1/5 for each following second. getSamplingRate give
you the number of samples per second in a given sound.
def increaseAndDecrease2(sound):
Question 3:
Complete the following function. The function increases linearly the first half of the sound then
decrease linearly the sound until it reach 0 in the second half.
def increaseAndDecrease3(sound):
Question 4:
Transform the reverse function done in class to use the index array notation instead. The
beginning of the function is given:
def reverse2(source):
target = makeEmptySound(getLength(source))
targetSamples = getSamples(target)
sourceSamples = getSamples(source)
for sourceIndex in range(0,getLength(source)):
Question 5:
Transform the copy function done in class to use the index array notation instead. The
beginning of the function is given:
def copy2(source,target,start):
targetIndex = start
sourceSamples = getSample(source)
targetSamples = getSample(target)
for sourceIndex in range(0,getLength(source))
Question 6:
Transform the clip function done in class to use the index array notation instead. The beginning
of the function is given:
def clip2(source,start,end):
target = makeEmptySound(end - start)
sourceSamples = getSamples(source)
targetSamples = getSamples(target)
for targetIndex in range(0 ,getLength(target)):
