Question

Using Python answer the following; Write a function clampsample(value, typecode) that uses the previous exercise to return value clamped into the appropriate range for type codes "B" and "h." Because samples must be integers while value may be a float, have this function return an integer. Where, The type codes corresponding to data in WAV files are: B Unsigned I-byte integer. h Signed 2-byte integer. And the answer to the previous exercise mentioned is; Write a function clamp(x, a, b) that returns the value of x clamped to be in the interval [a, b clamp(x, a, b)= b ifr >=b otherwise r def clamp (x, a,b return max (a, min (x, b))

Explanation / Answer

1 byte = 8 bits

This correspondingly helps define the range for B and h.

B : Unsigned 1-byte integer = Unsigned 8 bits of Integer data. Thus, Range = 0 to (28 -1) = 0 to 255

h : Signed 2-byte integer = Signed 16 bits of integer data. Thus, Range = 216 to (216-1) = -32,768 to 32,767

Therefore required funtion snippet is as below::

def clamp(x,a,b):

return max(a, min(x,b))
  
def clampsample(value, typecode):
if(typecode == 'B'):
return clamp(value, 0, 255)
else:
return clamp(value, -32768, 32767)
  
x = clampsample(263555, 'h')
print(x)

I hope this is helpful. Please revert back in case of any query. Thank You
