I wonder, how would I find "0 Crossings" in the original file I sent? When I
tried the crossfadein and crossfadeout plugins, unfortunately, the fades
were not at constant gain. So when I played it in loop mode, it would dip
down in volume at the end, and back up when it rewound to the beginning. I
want it to sound like a constant ambient track, in other words, at the same
volume when it rewinds to the beginning from the end in loop mode. Here's an
example of a sound that I have which is an ambient background sound. This is
an .ogg file, so I hope it works for you to listen to in Audacity's loop
mode. This way you can hear what I want to try to achieve.

Hi Annabelle!
Nice one. I had a go at this.
https://dl.dropboxusercontent.com/u/6687164/White%20Zone%20No%20Parking%20lo
op10x.wav?dl=1
First I trimmed roughly 11 seconds of silence at the end. Since you had
already faded the street noise in and out, I selected the audio from start
to finish, copied it to the clipboard and positioned the cursor just after
the female no parking announcement. Then I added a new track and pasted the
audio. This created an overlap which due to your fades, amounts to a
crossfade. When I had five tracks, I selected all and mixed them down to
one. Then for good measure I selected that mix and added another track as
per above. This gives you 10 cycles. Anyone staying in the white zone for
that long can definitely be accused of parking...

The Audacity manual recommends working with Zero Crossings when creating
loops, but I prefer to use crossfades. They give you more freedom regarding
the length and sound of the overlap. I find that this method works
particularly well with ambient noise.

Cheers! Robbie

Hi, it's Annabelle.
I'm trying to loop this bit of audio that I've constructed from three
different clips, I want to make it so that it will play as a loopable
background sound. How would I do this? Here's the file in an attachment.
