Simple audio cutting

Based on the PyDub page...

from pydub import AudioSegment

song = AudioSegment.from_wav("bbcnewssummary.wav")
first = song[:3000]
last = song[-3000:]
x = first + last
x.export("x.wav", format="wav")

Loop!

from pydub import AudioSegment
 
song = AudioSegment.from_wav("bbcnewssummary.wav")
tape = AudioSegment.silent()
for x in range(120, 0, -1):
    clip = song[x*1000:(x+1)*1000]
    tape = tape + clip
tape.export("tape.wav", format="wav")

from pydub import AudioSegment
 
song = AudioSegment.from_wav("bbcnewssummary.wav")
tape = AudioSegment.silent()
for x in range(len(song) / 1000, 0, -1):
    clip = song[x*1000:(x+1)*1000]
    tape = tape + clip
tape.export("tape.wav", format="wav")
