Hey All,
I'm trying to loop a segment of a vocal take, so I could hold the singer longer throughout the song, kinda like time compressing but instead looping, but I'm having problems adjusting a smooth loop, with no pops, the auto C button works, though its not a steady smooth loop.
I tried this once in wavelab with crossfading and it worked, but I'm trying to get these result's from the e5000, anyone have any ideas?

Thanks!

When you are in the loop screen;

aproximate where you want the loop

Zoom in fully so you see something like this



with fixSize on shuttle up and down through the wave until you see a simila curve in both the 'eol' and 'sol' windows. - they might be a fair bit apart, mind.

turn off fix size, the move either the Start or End position to the similar bit of the wave curve.

make sure that the curve meets in the centre line, misalignment here is what causes the clicks.

Finally turn on fixSize so you can shuttle up and down the wave to check that the curve looks right (It should look like there is no seam in the middle)

Now you should Audition the sound to hear how the loop sounds - it shouldn't click but it might sound a bit robotic if the loop is too short or the pitch varies. About 1sec of continous pitch/volume is enough to trick the brain into thinking its natural IMO.


E-mu has a really good system for loop matching, if not one of the best. Even if I have been setting up a loop for the PC I have edited on the e-mu as it is so quick. I use wavelab less since I have had the sampler!

You could also do this. After setting your loop points, if it still clicks you can try the options in the next screen. You can have the emu do a crossfade. You can also adjust how much cross fade is applied. You can crossfade with either Equal power or linear. Then you can compress the loop as well to control swells abit. You will just have to play with it. I made a vocal loop that sounded good. I also use this to extend pads that I sample and use. This tech can also get rid of the poping and clicking that you hear from missed zero crossings. It can also cover up alot of the sounds variations with this.

I had a sample of someone saying dance and I wanted to loop the the last bit and by using the option described above I got something that sounded like this: Dansansansansans and so on. I then used a filter adsr to have the vocal filter out the voice so it would fade off. It sounded smooth and natural if you want to call that natural.

The looping is vital to sound design as well.

Sounds great...

What's 'filter adsr' mean?

I would say that glitches/clicks have their place too though... always depends how it sits in the mix. I adjust stuff like this in the context of the tune, ie as the section containing the vocal loop is all looping.

"Filter adsr"

What does it mean? You have 3 envelope generators in your emu. I call them adsr's. So you have an adsr for your amp, your filters, and for auxillary for your filters or amp or whatever you need it for.

adsr stands for Attack, Decay, Sustain and Release.

You have two steps in each adsr section, 2 attacks, 2 decays, 2 sustains and 2 release.

So when I referenced my sample I used when I sample the word "dance" and applied a filter adsr, it was in reference to the filter envelope generator, so I could have the sample filter out over time with out the need to write cc data in my sequencer.

Hope this helps.
