Subject:Sustaining loop
Date:3/27/2013 3:54:44 PM

Hi,

I'm a newbie in the world of sound forge, so expect my question to be easily answerable.

So I have a piece of piano that ends almost on a humm for about 5 seconds. I want to extend that humm for longer (and possibly increase the volume). I'm thinking that I need to create a sustaining loop, but I'm wondering how it's going to sound contiguous across say 5 loops of the original, particularly at the joins.

I tried just taking the section I wanted and pasting it 5 times on the end, but the 'joins' sound naff, almost like a click, whereas I want it more fluid sounding.

so more like

hmmmmmmmmmmmmmmmmmm

rather than

hmmmmm-click-hmmmmm-click-hmmmmm-click-hmmmmm

Any ideas anyone?
Many thanks in advance.
Colin

First off, make sure you're making the edit at a zero-crossing, preferably at the same point in the wavelength. You may also find it better to loop a smaller portion of the tail, so you don't get as much of the natural decay.

Hi Rob,

Many thanks for such a prompt response. Having read your response, I searched and found this, which I think helps me with some of the basics

http://www.sonycreativesoftware.com/10_ways_to_work_faster_in_sound_forge_pro

and this more specifically

Although the latter is taking a little time to sink in, particularly Step 6.

Thanks again Rob
Colin

This tutorial was a turning point...

Glad you got it sorted.
Although after-the-fact in this discussion, the three biggest rules of loop creation are:

1. Cut only at zero crossings. Since these can (and do) exist at subsample levels, zoom all the way in.

2. Never encode a loop as .mp3, only as .wav, at the highest practical sample rate and bit depth.

3. When in doubt, refer to rules #1 and #2.
