Editing audio regions

I have two questions regarding editing audio regions that I had difficulty with. After referring to the quick start manual and the manual on the help menu, I was unsure how to proceed.
1) Sometimes when I want to divide/cut an audio region so that I can copy part of it to another part of the track, I don't get it exactly at a zero crossing. I zoom in ALL the way possible and whenever I try to drag the corners to a zero crossing, I always jumps and cuts off another wave form. I'm having a lot of trouble getting the regions in the zero crossing. I tried double clicking on the region, it opened a type of audio editor. In the edit menu (I think), I checked the "zero crossing". When I zoomed in there and tried to adjust the selection or start, again it would not let me. Can someone please point me in the right direction.
2) When I am moving regions on one track and there is a little bit of overlap, one region always cuts off the other one. I am having trouble figuring how to make logic understand which region I want "on top" and also wondering if there is anyway I can have the audio from both regions play simultaneously while they overlap on the same track.
Thanks very much,
~Nico

okay, to answer Q:2 first...if there are two patches of audio overlapping, one will cut to the other as the scroll point reaches and passes them. if you want both to play simultaneously, put one patch of audio under the other, on another track.this is the quick and easy solution to that problem
for Q1, well there are a few approaches for editing audio. an easy way is to copy/paste the audio to the area on the arrange page you want it to be. double click it to open the audio edit window, then use the little in/out points at the left and right bottom corners respectively (they look like little triangles). move these points to the start/end point of the section of audio you want. you can make these points very precise. at this point you may want to go to the FILE drop down menu and 'save the selection as....', name it and add to audio window. then it will be named here to be re-used/edited without affecting the original audio. if you want to cut within a waveform, you can apply little fade in/outs to stop any clicking. remember any edits you make to your original pieces of audio are usually permanent, so always worth copying and renaming patches you are editing.
hope this helps, as i say, there are so many ways to edit audio, so i'm sure another user will give you some different advice. the more you experiment, the more you'll find little ways to do things.
as long as you have copies of the audio you are editing, just play around with it, untill you discover things...thats the best way.
good luck

Logic freezing when editing audio region lengths

If I'm editing a track by chopping it into 4 bar pieces and then time stretching each section to get the tempo constant I get a very strange bug. It will do the audio stretching fine, but as soon as I click the menu bar to save, the program freezes and sits on 50% CPU load indefinitely, not allowing me to do anything, meaning I then have to kill the process and lose my work. Anyone know what's going on or experience any similar issues?

Hello Caramby,
These audio files don't have buzzing or clicks in them, if they did the producer on session would have probably changed engineer lol. I'm cutting several files at once grouped in Logic: the DI feed, and the mics around the amp - so in total around 7 mono audio files. The buzzing sounds like a clocking issue rather than artefacts in the track as when I quit LP7 and reopen the audio and play it all the way through its fine - and I would also see any artefacts in the audio as I'm cutting pretty much to the sample, and then moving it to get it in time.
As you read in my original post, I can start editing and it be fine for 30 bars or worse and its 2 bars. When it happens and I press the Control+Shift keys (to fine tune the cut) and get the scrubbing sound of the audio, I get this clocking buzz...
The session was done in at a commercial studio ProTools 8 but our studio works mainly in Logic 7.2.x (with TDM hardware) as we find it a little easier to use (until we can get our hands on a stable version of PT8) So the audio needs to stay in LP7...
Hope this helps!

Unable to edit an Audio Region (just want to change gain)

Hello,
In a particular audio region I am unable to change gain in that the "Change Gain" command (as well as all the other functions) are Grayed-out FOR THIS REGION. I am in Sample Editor>Functions>Change Gain.
There are over 200 audio regions in this file. Most of them have NONE of the edit functions grayed-out.
A few other regions have all the edit functions Grayed-out except for Change gain.
Almost all of the audio regions are from apple loops. I have not edited any of the regions except for some regions ending points, and volume automation added.
Why would this one particular audio region ("Country Night") by un-editable?
(NONE of the tracks are locked.)
please help

Is it a file in .caf format? If so, note that compressed Audio formats can't be edited destructively. Convert to aiff/wav before.
Btw, there is a Gain function in the Region Inspector since Logic 9, so there is no need to change the gain in the sample editor anymore.

Edit length of audio region

I've looked through the manual on this one but can't find out if the following is possible.
I have an audio region and I want to extend the length of it so that it begins/ends on an exact bar but I can't seem to do this.
I have tried creating a blank audio region, to fill in the gap as such, then tried to glue it to the original audio region but I get the error "Folders and Regions or Aliases cannot be merged".
There must be something fairly obvious i'm missing here so if anyone has any suggestions that would be great.
Thanks
Bryan

Hi TS,
Try page 314 of the LP8 User Manual: "Adjusting the Start Point of Audio Regions". That should help.

Jerky track and Audio Region movement

I am playing back some GB sessions that i made in GB 08 that worked great. They play back okay in '09 as well but the scrolling is super jerky now making it hard to accurately edit automation and such. Why would these sessions all play back silky smooth on GB 08 but be all jerky in GB 09 with zero changes? I saved the session as a new GB 09 session thinking that was it, but no the playback is still jerky. Is there something i can do to make this smoother?

slide the "track" or slide a "region"?
i can resize the audio region with hand icon but it will not reduce in size.
grab the bottom left or right edge of the region and drag
SOMETIMES the audio region will remove itself when i slide the upper track down but MOST times it will not remove.
sorry, no idea what this means.

Copy/paste automation data in audio regions

Hi,
A dumb question but I'm having trouble figuring out...how do I copy and paste automation data in audio regions? When I copy and paste an audio region I like, it pastes down the selected region but without the automation data with it. I've been rewriting the automation data every time to the newly-pasted region but I'm sure there's a simple way to do this. I've looked through the various help files but still am struggling to find the procedure. Any advice is welcome and thank you.
Respectfully,

OK, for viewers of this topic I figured this out myself. There are two lines in the reference manual that pertain but even they were a little confusing. They read:
"Option - long clicking on a selection allows you to copy the selection." p.234
I had success by using the pointer tool and selecting the automation data within the region by holding shift+dragging the mouse over the target data. The data highlights white. Then with the pointer tip on a line of the selected data, holding option+long clicking the selection AND dragging the data while still holding the option key I was able to drag and drop the automation data to a new region in the track. That got me "in the ball park" so to speak but fine tuning the actual drop was necessary to assure precise nodal location. That can be done node by node or better by dragging the entire automation selection as a loop edit.

Editing audio and samples- garage band fit for the job?

hey folks,
I'm rather new to Garage band but know other applications quite well (i'm an Acid & soundforge convert).
A few questions to help get me up to speed.
Garage band is great for loops and recording but what about editing samples and existing files?
For example, I have hours of recorded sounds from the streets, etc that I'd like to chop up into loops. Im having trouble zeroing in with garage band on start and endpoints for cropping...
Is Garage band an 'all in one' or are you expected to use an external editing software to do this? IF so, what software are most people using for this?
next question. any easy way to reverse a file in Garage band??? how about use your mouse cursor to define the start point in playback (Kind of important when you're zeroing in while editin).
Sorry for the loaded questions = these are my roadblocks right now...

what about editing samples and existing files?
An audio editor is a better chocie for, well, editing audio:

Can't fade audio region with multiple takes

Audio track: I have some sections of a song with a single vocal take on the track (individual audio regions), and others with multiple takes. On the single takes, I can use the crossfade tool, no problem.
On the sections where there are multiple takes and a few edits, I cannot fade. I drag the fade tool at the front of this region and it does not fade. In fact, the highlight color is green as opposed to blue (when it works on individual, single-take regions).
How do I use the fade tool on an audio track where there are multiple takes?
(Please don't tell me I have to bounce this section of audio and re-import it...)
(There is nothing in the manual on this. I checked: pages 343-345 discuss fades in this regard but there is no mention of it not working for a multiple take audio region.)

You don't need to bounce the track, but you do need to collapse the takes into a single track. Do your comping until you have the track you want, then use the little menu button at the end of the track to fold everything into a single track (I forget the correct terminology, but it's pretty obvious when you open the menu), then fade to your heart's content.

Help getting desired audio region into the sample editor

Chapter 21 of the manual is of no help. Assume I have to audio regions on the same track--singer sang first part of song..... big pause... then sings second half of song ( same track but two distinct ausio regions) All I want to do is be able to quickly have a desire region show up in the sample editor to do edits. The actual instructions about editing are pretty clear. But getting the correct region to show up in the sample editor is the hard part. Even if I click the audio track and click the audio region desired, some other region or some region on another track will be there. And I can't change. This shouldn't be that hard. +I do not to have this problem with piano roll and software intrument regions. You simply click a software track region and click piano roll and the detail of the region shows up+...... Is there a simple protocol for getting a desired audio region to show up in sample editor. Notice that there is no clear explanation for this basic, antecedent task in Chapter 21.

You can't really 'quantize' audio. If it is a single track like stacatto mute guitar, or snare drum hits - you could. Use the 'strip silence command' and then in the list editor highlight all the individual pieces of audio and quantize that.
But if the audio is continous or there are too many notes very close together you will not be able to do that.
If you mean that the track was a 'real guitar' (by musiclab) - yes you can quantize the midi notes.

Audio regions getting moved about when i delete/shorten/move other regions

this has happened in a few projects now. i have tracks containing multiple audio regions, and when i try to edit just one of them, the others are affected. if i try to make a left or right corner change, or simply delete a region, all the other regions in the track shift towards the edited region. i just want to be able to work on a region independently without it messing with the other regions in the track.
also...i´ve recorded a vocal section where i basically am just singing "ooooooh" the whole time. i wanted a continuous "ooooooh," so i made a copy of the original region, reversed it, and pasted it to the end of the original (hoping to avoid any clicks between regions). problem is, the region automatically fades the volume slighty at both ends no matter where i cut it, so there still is a bit of a click.
i appreciate any help you can offer
thanks

*Question One:*
It sounds like the Regions you are editing are Clones.
Clones can be created for audio regions (by Option-Shift-dragging). These are comparable to MIDI region aliases, but differ in that adjustments to the start or end points of any cloned region will affect all other cloned regions in the same way.
Adjustments to the source region do not affect clones.
You can, of course, create independent copies of audio regions (by Option-dragging), which can be adjusted without affecting other copies or the source region.
_To make several cloned regions independent of each other:_
• Select the desired (cloned) regions and choose +Audio > Convert Regions to New Regions+ ( or use the corresponding key command, default: Option-Command-R ) in the Arrange area.
Cloned regions that are made independent in this way can have their start or end points altered, without all other cloned regions being affected.

Midi and audio regions are getting moved

Hallo... I am working on my arrangement on Logic Pro 9.1.8. I have many midi regions on a few tracks. I added a few audio tracks and started to slice them and reversed some parts. (I also played with new key commands) Now all the regions on each track (midi and audio) seem to be tied up. When I delete one region all the others (on this track) shift toward its position. Why does it happen?
(Locking SMPTE position partly helps but I would like to have access and be able to edit the regions). Any help would be appreciated.

Sounds like you've got your drag mode (upper right of arrange) set to one of the shuffle settings.

Changing the volume of a specific Audio Region in the arrange

Is there the possibility to increase or lower the volume of an individual audio region? Similarly to the way one would use the hyper editor for a midi region? So to clarify it in other words. I would like to increase the volume of a specific audio region in the arrange page without using the track automation.
<Edited by Moderator>

Just open the sample editor (default key command "W", or double click the audio region). Highlight the waveform area you want to gain change by clicking and dragging your mouse across it, and under the functions menu, select "Change Gain" (default key command control/G).
This is destructive editing, although the sample editor has it's own undo history, separate from that of the Logic song.
To play it safe, make a copy of the audio file first, and edit from that.

MOVING AUDIO REGIONS PROBLEM! HELP!

SO, I recorded a 3 piece band live...great,
when i was recording guitar overdubs, i dragged the audio regions over to make room for a guitar intro, but i didn't select all the other overdubs...oops.
after recording the intro at that location, i found that some of the other overdubs weren't lined up!!!
Is there a way to snap regions back to where they were recorded relative to other regions!
**NOT move region to original record position. that doesn't help because the original record positions are different for different overdubs. I tried dragging them back manually, but that takes forever, and i'm afraid there will be phase issues if it's not exact where it was tracked. please help.

Well, I tried the undo list which I haven´t used before. Mainly because I never make mistakes.
I admit I couldn´t get it do it exactly the way that would be useful for you. It´s not like actions in Soundtrack Pro. The undo list gets slightly confused if you try to undo one action in the middle of many. I actually get warnings about messed up time continuums and other sci-fi like messages...
The event list thing is really handy. If you open a previous version of your song where the regions are where they´re supposed to be you can select them. Open the event list. There you´ll see where they all start.
Make a mental note of where the first or topmost region begins (or double click and copy the info). Switch to song 2. Select the relevant regions. Move all these regions to the same start as in song 1.
(Or you can do it one region at a time, hence the suggestion to have two edit lists open simultanously. Time consuming, but possibly succesful.)
Hope this helped!

How to enlarge audio regions without timestretching (adding silence) ??????

In the Arrangement , id like to be abl to enlarge audio regions , so they fit in the length i need , but im not speaking about timestretching .
I explain myself : I have many short audio files in my arrangement . To be able to manipulate easily these regions , i want to enlarge them so they fit in the bars or in the loop , then i can just copy them or move them accurately . this is useful for un quantised region , wich can be a little difficult to move and copy .
Basically i want that logic creates a new audio file with silence before or/and after the region . Is this possible ?? How ???
than in advance

hi dup -- I think this will fix your problem:
1 - Slice off ( with the scissors tool) a bit of any audio region that already exists, copy it (apple C) and then paste it a little way away from your original audio region(OAR) on the same track. Then rejoin your original piece of audio region.
2 - Place the Song Position Line ( SPL) exactly where you want the new audio region (NAR) to start. Let us say it is at bar beginning of bar 3 or if you are using time code 3seconds.
3 - Select your snipped bit of new audio region(NAR) and using the key command 'Catch Clock' - the audio region will snap right up against the SPL. ( Make sure OAR is not selected or it will also move ..which you dont want )
4 - Now select the NAR and go to the Audio menu and find the command Convert Region to New Audio File. This will turn the NAR into its own independent piece of new audio.
5 - Double click on the NAR - the Sample Editor will open. Go to Function and select the command for Silence. This will turn the NAR into a completely silent lump of audio.
6 - Now you have a Silent lump of audio ( NAR) and your old region(OAR) from which it originally came from. Select both and use the command for Merge. ( This default key command is sometimes J)
7 - A box will come up which says something about 'non contiguous regions.. do you want to create a new audio file?'
The answer is YES
Here is a sort of diagram:
{NAR} {OAR}
becomes
{NAR++OAR}
The piece above which says Original Region will have your audio sound.. but NAR and all the new stuff in between.... + will be as Wm Shakespeare said "the rest is silence"

Copy/pasting audio regions between different tempo projects

hi, ran into a strange problem when working on a film voiceover...
did the recording the other week for a new language version. when done i converted the takes to 48khz as that's the rate in the original logic file. edited together the new, english version cutting and mixing together the best parts of 5 takes. ended up with about 200 nice audio regions in a row.
what happened is that when i tried to copy the new english version in the old logic project it gets totally screwed up. the reason being (i think) that the new project is 120bpm and the old one 77,7476 (?), which i didnt notice before.
is there any way i can
1) paste the 120 bpm stuff into the 77bpm stuff so that it ignores the tempo difference? – now the ends of the regions change, causing sentences to to end funilly, and there a gaps between regions.
or
2) change the 120bpm projects tempo to 77bpm without screwing it up?
or any other solution?
thanks,
/r

Hi Rikard,
Beforehand, forgive me for any overexplaining I might do. In case of underexplaining, just ask.
200 regions in a row? On one track, right?
1) If so, you could simply merge all the audio regions into one fixed file. Select all regions on the track and hit the '=' shortcut. Logic will tell you that it is gonna make a new file. This new file you can then import into the other project. Audio (not loop) files are independent of Logic's tempo. It is just that the bar division doesn't line up with the tempo anymore. But if that is not a problem...
Also I do not understand why the new project is at 120 bpm? Is there a reason for that, other than that it is the default value when opening an empty project? If not, just set it to the 77 something of the old project. If there is already stuff in your new project and now you want to add your 200-region audio, use method 1). If you change the tempo, two thing change: the tempo of any mioditrack, and the time between audio regions. The audio regions itself will not change.
regards, Erik.
