Improving the join of two wave file?
- by kaki
I have written a code for joining two wave files.It works fine when i am joining larger segments but as i need to join very small segments the clarity is not good.
I have learned that the signal processing technique such a windowed join can be used to improve the joining of file.
y[n] = w[n]s[n]
Multiply value of signal at sample number n by the value of a windowing function
hamming window w[n]= .54 - .46*cos(2*Pi*n)/L 0
I am not understanding how to get the value to signal at sample n and how to implement this??
the code i am using for joining is
import wave
m=['C:/begpython/S0001_0002.wav', 'C:/begpython/S0001_0001.wav']
i=1
a=m[i]
infiles = [a, "C:/begpython/S0001_0002.wav", a]
outfile = "C:/begpython/S0001_00367.wav"
data= []
data1=[]
for infile in infiles:
w = wave.open(infile, 'rb')
data1=[w.getnframes]
data.append( [w.getparams(), w.readframes(w.getnframes())] )
#data1 = [ord(character) for character in data1]
#print data1
#data1 = ''.join(chr(character) for character in data1)
w.close()
output = wave.open(outfile, 'wb')
output.setparams(data[0][0])
output.writeframes(data[0][1])
output.writeframes(data[1][1])
output.writeframes(data[2][1])
output.close()
