Here's another tip for effective cross-fading of tracks or loops dj-style - some subtle differences to a cross-fade can make all the difference to the flow, as any good dj will tell you.

Most people probably use the fades window in quick preset mode. But it is actually a very flexible tool that lets you shape fades in a multitude of ways.

One oft-overlooked aspect of crossfades is that they don't have to be symmetrical. Different fade-in and fade-out times can be set in the same window, adding that extra 10% to your mixes  :cans:

I'll demonstrate with two basic tracks, very roughly beatmixed and centred on a drop-out in both tracks as the transition point. Track 1 has a sawtooth stab line and track 2 has a plinky arpeggio.

*NB the following can be done with separate tracks and basic fade-in/out on each but this is more fun ;)

The first pic shows the tracks lined up and prepared for crossfading:

The two tunes not faded yet (bit messy ey?)

The next pic shows a symmetrical crossfade with exponential fade out and fade in to create a soft transition in the middle. This can be done either with the Smart Tool or by highlighting the area and typing cmd-F. Note in the fades window the 'Link' button is set to None and black dots have appeared on the red and blue fade lines:

The symmetrical mid-point fade:

[mp3=200,20,0,center] [/mp3]

An important thing to try and see (and hear) is that by highlighting 4 bars in front of region 2, the arpeggio in region 2 has started fading in from this point - i.e. 4 bars earlier. The idea is you fade into the region, not start fading at the region. This is why I trimmed off 4 bars to start with. The trimmed 4 bars were not deleted, just made temporarily invisible. I can now reveal as much as I want in the fade in half of my cross-fade.

Conversely, the fade out here ends 4 bars after the mid-point and the remaining drums have been rendered silent - in fact by replacing them with track 2!

Now for some changes - the main one I want to show here is those black dots - by dragging them back and forth you can change when each fade begins and ends, independently of each other.

This one has the fade-in half as long, so the arpeggio is full-level by half-way and the bass fades under it:

The early fade-in:

[mp3=200,20,0,center] [/mp3]

This one has the fade-out starting half as late, so the synth is full level until the bass starts:

The late fade out:

[mp3=200,20,0,center] [/mp3]

See the possibilities? There's dozens more shapes you can explore, and each will help you reveal different elements in very subtle ways.

ps - these fades are a secret weapon of speech editors fixing or making new words by replacing single syllables - with Pro Tools there is always a way to make an edit seamless ;)

Stirling work there, son! Great the way you've aligned the Fade window against the regions. Perfect illustration of what's going on. And neat clips too! ;)

Hehe.. reminds me of a friend who'd carried around a tape recorder around the school playground in our early high school years... only to pull them out a decade and a half later, much to our amusement. We then set about editing them to remove the sibilant pops and rough microphone handling through the hours of recordings... we became quite good at getting the various mid-sentence edits to appear virtually seamless.

Anyway, we're certainly compiling a chunky set of tutorials here. I really hope it inspires the other S'Punks to work on similar pieces for their respective forums. Very valuable reference for those still finding their way on a new audio application.

Cheers mate. 8)

^ No worries, actually enjoy these little tutes and I'll point my students to them - they'll be handy references.

Yer those mid-sentence mid-word clean-ups. I once edited training CD's for a large Telco I can't mention (confidentiality contract has my ass). I had to remove every cough, stutter, umm and aah, fix distorted plosives - you know the deal. Hours and hours of tedium listening the joys of line rental or the madcap antics of call centres or how wonderful the internets is...

As you guys would have noticed though, those hours of tedious editing make you a gun shuffler and fader!

ps I'll post some more screenshots of my favourite shapes on the weekend - without audio too tedious ;)

How about you just post some of those telco samples? I'm sure i could start up 1800-love-balls using them and an auto-answer service ;)
