Sample audio

http://pzwart3.wdka.hro.nl/prototyping/bbcnewssummary.wav

Installing on OS X

Download the latest code (as a zip)
Open the Terminal
"cd" into the folder with setup.py

sudo python setup.py install

If it complains about setuptools missing, do this:

sudo easy_install setuptools

... and then repeat the line above.

Linux

Download the latest code (as a zip)
Open the Terminal
"cd" into the folder with setup.py

sudo python setup.py install

If it complains about setuptools missing, do this:

sudo apt-get install python-setuptools

... and then repeat the line above.

Running / Using pydub

Open terminal
Start "python"

  import pydub

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")
