Editing music using Audacity

This one is for all the people who like music (who doesn’t btw?).

I will demonstrate how to edit music using a free software called Audacity.
Specifically, we will be editing ‘mixtape’ kind of music, in which there are multiple songs interwined into a single track.

The background behind is this – a looonng time back, when the Earth’s crust was still solidifying, I used to listen and record radio on Saturday nights, where some very talented DJ’s would play fantastic music in the form of a megamix.
The problem was that the DJ would keep on blabbering something in between and I used to like at max 40-50% of the songs in the whole thing.
So, I decided to “cut out” those songs from the recording.

Although I have stopped listening to radio, I still download fresh music from Youtube illegally (shhhh! don’t tell anyone pliez), and edit that according to my taste.

So, here are the steps:

  1. Download Audacity from here. You might want to download the Lame mp3 encoder if you want to export music as an mp3 file, and the absolutely fantastic piece of software called FFmpeg if you want to edit a much larger variety of music file formats.
  2. Get a mixtape from somewhere and rename it as tomato_is_actually_a_fruit!!!1.mp3.
  3. Fire up Audacity and import the mixtape by navigating to *File* -> *Import* -> *Audio*. 01_welcome
  4. Click on *Save project as..* because Audacity hangs too much.
  5. Note down the segments of the track which you dont like (you can do this in your favourite music player if Audacity seems inconvenient for this). Make these observations as accurate as possible. 02_unwanted
  6. For all the unwanted segments between timestamps t1t2, do the following:
    • Delete the segment by applying Split Delete to it (*Edit* -> *Remove special* -> *Split Delete*
    • Apply Fade Out to the segment t1-00:00:15 (15 seconds pre t1) and Fade In to the segment t2+00:00:15 (15 seconds post t2). This is so that it does not feel as if the individual songs are ending abruptly.
  7. Finally at the end of the mixtape, if it ends abruptly, apply the Studio Fade Out effect (*Effect* -> *Studio Fade Out*) to the last 30 seconds or so.09_studio_fade_out
  8. At this point, all the unwanted music has been removed. We now need to combine the remaining part. For that, first add a new track; *Tracks* -> *Add New* -> *Stereo Track*.
  9. Keep saving the project frequently as Audacity hangs too much.
  10. Now, starting from the beginning, shift every existing segment to the left to align with its previous segment in alternating tracks such that the end of one track overlaps with the beginning of the next track on its right. (1st segment in 1st track, 2nd segment in 2nd track, 3rd segment in 1st track and so on…)
  11. You are done! At this point, you will be pretty astonished at how easy it was, so just unplug your computer and take deep breaths.
  12. Fffffuuuuuu…. forgot one thing! To save everything, *export* everything [ as an mp3 (quality = ‘Extreme’) or as an ogg (quality = 5) ]
  13. If all your progress was lost due to step 11, then go to Step 1.
  14. Share this post every where you can; Facebook, Twitter, Youtube, Google+ (you should introspect if you are using this btw). Spam it to every one in your Gmail contacts. Whatsapp to every person you know, even if it risks your friendship with them.  This step is the most crucial one! Without this, your music will sound more lifeless than my 1-million-year-old grandma.

I have screencasted the whole process and posted a live demo here for all the folks who don’t know how to read.

As an example, this is a random mixtape, and this is the result post editing.
