Screenshot #241: Once recorded (if applicable), I begin cropping the file as needed. The start is easy - the point where the silence ends. The cursor position marks this quite well.

Screenshot #242: This area is the location where the silence from the lead-in ends. This screenshot shows the end of the part I delete. Each of those ticks represents one sample. A typical CD plays 44,100 of these each second per channel. This means the pitch cannot go any higher than 22,050 Hz, slightly above the limit of human hearing.

Screenshot #243: From there, I just extend the selection to the start and delete it.

Screenshot #244: The other side is done in a similar way, except it's more complicated. To get seamless looping, you need to have an understanding of frequencies and waveforms. The point where the song actually begins the loop is where the cut off point is. For optimal and best results, I need the intro, 2 full loops, and the first few measures of the third loop's start. That location is about where the selection is at. I only need to fine-tune the selection, done by playing the song with the end being about where the end of the loop is at. If I hear anything odd, I'll know that's the point. To help with doing this, I also change the speed of the song. In this case, it's 65% true speed for this particular song sounds its best. Slower speeds allow longer durations of these tricky parts. The screenshot shows about the center of this point.

Screenshot #245: Zooming in and centering the selection to where the transition occurs is what this screenshot is of. Do you notice the difference in the waveform on the left side and the right side? The left side is lower in amplitude (aka volume) and has the higher-pitched parts stand out more due to higher amplitude ratio. A higher pitch is noted by the crests and troughs being very close together, using fewer samples for each curve cycle. Midtones are also visible. You should be able to make out a sound that's about 500 Hz here.

The far right has a 2000 Hz sound suddenly becoming quite loud. This is often due to cymbols and certain drums. This sharp change in the waveform makes this song easy to edit. The area at 336.2675 seconds in (becoming 218.5739 seconds at true speed) is the point I mark for a deletion.

Screenshot #246: Once I find the zero point, a standard I use, I select from that zero point position and everything after it and delete it.

Screenshot #247: With the song now done, I have the intro and 2 loops version of it. I save this result as a WAV file. Why WAV? It's a lossless format and I always convert later.

Screenshot #248: Making the loopable version is next. This is done by finding the same point from the previous few steps, except at the end of the first loop. Here, I'm marking the zero point. Zero point? When you have silence in a song, that's where it goes. Everything above and below this produces the actual noise itself. I then extend the selection to the left of the zero point and delete. That completes the loopable version.

Screenshot #249: Just to make sure it's good, I copy the whole thing and paste it at the end. I check for any "tick" sounds and also check the waveform to see if it lines up like I expect. Given this, you can't tell a difference from the original!

Screenshot #250: After undoing the paste, to get the original single loop, and setting the sample rate of the waveform back to true speed, I save the final result in the same way except, instead of "intro and 2 loops", it's just "loopable". The following video is for another song, done pretty much the same way.
