Time and Pitch Machine questions

Hello,
I am a recent (and so far very happy) convert to mac and it's audio environment. I knew there would be some "re/un-learning" to do and I have come across this:
1. I need to slow down a section of an audio track (saxophone) to match a piano accompaniment. The student played a bit too fast in one spot. Instead of re-recording, I assumed I could, in post, fix the problem. I read and followed the manual's instructions (95% sure on this) on selecting the section, opening T&P machine, choosing parameters, etc., and then:
When I pre-listen to the section, there is NO change/alteration in the speed. Even if I go extreme (just to see if it is working) I get nothing. Does anyone have any insight? I don't want to write this to disc until I know it is correct.
2. One more thing: I come from a PC world of Sony Vegas and Sonar, where you can use an "envelope" line to "draw" in various changes (like playback speed) over an audio file. Reaper also does this. I really like this feature, but I have not (yet) found it in Logic 8. Is it there?
Thanks,
Scott

A simple method I use is to make a backup/duplicate of the section that needs to be changed. Save it as a new audio file and import it to the Audio Bin.
Using the duplicate, carry out your tempo/pitch change and click Done ( or whatever the button says ). That way, if you don't like the result, you won't have damaged your original file. In fact, all destructive edits should be done on a copy of the original audio file.

  • Can't access Time and Pitch Machine

    I have highlighted the audio region in the sample editor that I want to transpose and speed up but Time and Pitch Machine in the Factory folder remains greyed-out. I have tried every possible combination between the arrange window and sample editor. HELP, PLEASE!!

    I converted the region and time and pitch machine still remained greyed-out using the new region. Any ideas?
    Have a look at the permissions of the the Audio path folder where you converted the region or just copy the converted audio file on the desktop and import from there to check if it is a permission issue. If it is the issue you have not convert the original region at all - just set the permissions...

  • Time and Pitch appears completely unusable at 96k (I/O Error-36)-any ideas?

    Hi there,
    Any help for the following gratefully received. Sorry about the excessive length of this post, but I've tried a whole bunch of things trying to sort out my problem and I'd rather list them all in the interests of clarity. (or should that be catharsis?)
    My simple question is: Is there anyone out there who is successfully using Time and Pitch compression / expansion at 96k? I simply can't get it to work with any degree of reliability on 2 new machines I've tried it on, and I've even managed to crash the demo machine in my nearest Apple Store trying it out.
    Some background: I recently ditched my TDM PT HD system in favour of a core audio Apogee Symphony based one. I use time compression / expansion of audio files extensively in my projects, and previously used the DAE version of Serato Pitch'n Time to do this. I've never rated the Logic Time and Pitch engine, so knowing that Serato and Izotope have developed Logic friendly algorithms was a big deal for me in finally making the hardware switch to a Mac Pro Twin 3.2Ghz Quad a few weeks ago.
    I've had quite a few problems / errors running Logic since then, resulting in me swapping the Twin 3.2Ghz Quad for a Twin 2.8Ghz Quad a couple of days ago. I reckon most of those errors are outside the scope of this question, but I'm happy to reel them out if people perversely want this post to be even longer. All those errors now seem to be sorted with the exception of the following:
    I've been trying to carry out a series of time compressions and expansions on a stereo 96k audio file to get it to play in time with my track, but the time stretching doesn't take place - I've been getting the 'I/O error Result Code= -36' message when I click the Process button. Not every time, but almost every time. It's more prone to do it with negative tempo change values for some reason, and if it does work, then an undo will almost certainly mess the audio up by not returning to the original state. It fails with both Logic's own algorithms and the dedicated Serato Pitch'n Time LE version. All other sample edit functions (say excite, denoise etc) appear to work correctly.
    Knowledge base here seems to imply that I'm getting a disk read / write error. I've tried resampling the audio. I've duplicated it and tried the copy. I've moved it to a different internal drive, having taken the first drive off line. I've moved it back again. I have four internal drives and I've tried audio running off each of them alone and in combination. I've given the file a new name with no gaps or punctuation. I've tried time stretching a completely different audio file chosen at random, usually to no avail but sometimes it works a few times, then fails. Mono files seem to be slightly more reliable, but not much. I've fixed disk permissions and all folder permissions more times than I care to mention. I've reinitialised the boot drive and reinstalled Logic. I've even installed OSX on a different drive, and installed Logic on that one, but that didn't work. I've tried it with my extra 8GB of (reliably sourced) third party RAM removed. I was getting this time-stretching error on the 3.2GHz machine as well, so you could even say I've tried it on two different machines (though it should be pointed out they had the same RAM and Hard Drives).
    At the Apple Store earlier today I tried to get a display machine (a 2 core MacPro) with a version of Logic on it (that I'd had nothing to do with) to replicate this error on the demo Logic song. When everything was 44.1 time stretching worked absolutely fine, many times, but once I converted one audio file from its default 44.1 kHz to 96 kHz and tried the time compression, up came the I/O error message. Now I can't believe it's a good idea to have different sample rates in the same song, so I converted all the audio files in the demo song to 96k in a different audio folder, changed the sample rate of the song so it would play back as you'd expect, saved and restarted, and then tried time stretching one of the files - it wouldn't do it, resulting in the I/O error again. Interestingly, after that even the 44.1 version of the song started showing the same error, even after another restart.
    It seems like I should work at 44.1 if I want to time stretch, but I like to work at 96k and I should be able to.
    This sounds like a proper bug to me and has been crippling my productivity, but I can't believe no one else has tried repetitively time stretching sections of an audio file at 96k - either have you been able to get it to work, or has anyone got any more suggestions I may not have tried out?
    Thanks in advance. (Or have you all gone to sleep by now? Self-editing was never my strong suit...!)

    Nevermind. I was low on disk space. Duh (though the error could have been a bit more descriptive).
    Move along. Nothing to see here, folks.

  • Capture time and folder organization question

    hi there,
    i just imported a a ton of photos to lightroom this past weekend.  a number of photos are dated incorrectly.  i changed the dates with "edit capture time."  now, i want the files to be resorted into appropriate dated folders.  does lightroom do this or do i have to manually move the images from a folder labeled with the old date to a folder labeled with the new date?
    also, when i organize by capture time, the photos in library are still not in chronological order by capture time.  i am using lightroom 2 on mac.
    thanks!

    There'll be one top folder, but LR wants to organize by date as you import, which is just right for most, and I am not suggesting eschewing this. Just on a mass of older images, etc., I personally wouldn't bother sorting them by date/folder unless you have a compelling reason, such as one's boss saying "that's how WE do it here...."
    I am a bit of a renegade, perhaps, in that I never use camera generated names/numbers*, and usually name the images after I've culled and edited, and (shudder) change the name of the folder from date to event or location. There are brilliant folk who'll say this is wrong, but it works for me. Nicely!
    * If you're backing up at the same time as Import, you're pretty much stuck with the camera numbers, afaik.

  • Call time and lifetime call question

    Hi all,
    I have just purchased a new Iphone 4, i noticed after 1 week that the call time is 3hr 18mins and the lifetime call timer is also 3hr 18mins. I have only used about 1hr of call time (both inward and outward calls) so why is this saying 3hr + when it should be about 1hr ?? is "data" time included in this ?? my wife got n iphone the same day and hers is on 1hr 7mins and she has used hers more than mine.
    Cheers Bill.

    How is your iPhone's display different?
    You can check the model number by  going to Settings/General/About. These are the model numbers for the various 3 GS models;
    MB715LL/A (16 GB Black), MB716LL/A (16 GB White), MB717LL/A (32 GB Black), MB718LL/A (32 GB White), MC555LL/A (8GB)

  • Time & Pitch Machine Basics

    I read the manual, but it doesn't say anything about this:
    When I import a song (.mp3 or .aif file) into Logic Express 8, I double click on the track and the Sampler Editor comes on in the bottom.
    Then I click on the Factory tab in order to access the Time and Pitch Machine, but it is DIMMED.
    Why on Earth? What do I need to do to make sure I can get it? Where do I have to click first? I have succeeded in getting the Time and Pitch Machine to work before, so I know I am doing something wrong or not doing something. Please HELP! Thanks in advance, Claudio Lessa

    I would like to thank the 121 people who have read my posting so far, although no solution for the problem has been posted.
    Please do not bother: after about a week -- and despite absolutely no clues given in any manual associated to this Logic Express 8 -- I found a hint on a book saying that a file must be an .aiff in order to be edited. I tried converting the .mp3 I had into an .aiff and... presto! It worked.
    So... if any of the 121 who read the posting so far did not have the answer, it is here.
    I would really like to see Apple to come down from its IBM-like posture and offer step-by-step manuals we could really use, instead of having to read about esoteric theories about how the sound goes into the computer and is processed. It is not everyone in this global economy who lives very close to resources/people who can solve last minute problems. Forums should be there to help even the most basic questions (in my case this one did not) but nothing replaces a good, detailed, step-by-step manual.
    Thank you for the attention.

  • Is this a bug? Time Pitch Machine Changes Gain Levels

    Logic Pro 9.1.4, macpro dual quad 2.93mhz, osx 10.6.8
    i'm altering the 'speed' of some of my 88.2khz aif files by a very small amount using Time and Pitch Machine, in Classic and Free modes ( -1.3% / -22cents apprx)
    but to my surprise i noticed that the levels of the file dramatically drops after a process.
    i expected some minr changes as its altering the length very slightly - but in the process i'm losing a great deal of level.
    eg: one original file that as un-normalised has a gain of 56.41% ( - 4.94dBu aprx), has dropped after the pitch change to 27.66% (-11.16dB) !
    thats a major loss of levels, and looks to be half of the original.
    can somebody explain if this is a fault?

    Well, the 44.1 test is just a test, you don't have to destructively convert your 88.2 files, just use 44.1 converted copies. I do agree that the drop in gain seems too much. It could well be that it is a bug related to the sample rate, so that's why I proposed the test. As for fidelity, you really do not loose much (if at all, audibly) when going from 88.2 to 44.1. Going from 24 bits to 16 bits at 88.2 will have a much greater (negative) impact then going from 88.2 to 44.1 at 24 bits.
    24/44.1 is much better than 16/88.2.
    Simple rule: if you can't hear the difference (test it blind! using ABXer http://emptymusic.com/software/ABXer.html
    (not sure if it is SnowLeopard compatible though... my Intel Mac is unavailable right now, typing from my old PPS G4 on Leopard)
    And, if you simply leave your original 88.2 files intact (use copies), you can experiment and listen without discarding your original highest resolution recordings.

  • Fatter vocals via Time+Pitch Machine?

    I'm looking to utilize the pitch change feature in Time and Pitch Machine to make a vocal "thicker". Now I understand this is gonna be a matter of opinion and one's ear, but I am not sure as to the settings and how to go from there. I can screw around and pick this or that till I hear something that sounds alright, but I'd rather have some background as to what I'm really affecting. Not sure how many cents to transpose or anything like that. Any suggestions would be well appreciated. Thanks

    Do you mean to create a vocal double track to thicken the sound? In that case, I wouldn't bother with the time and pitch machine. Well, you could I suppose create a copy, then shift the pitch on the copy by a couple of cents up or down, and perhaps shift the formants a little to change the colour somewhat. But you may as well do this in realtime by copying the audio to another track and using the vocal transformer plug in. Or, another trick is to use the pitch correction plug in on your double track, with light settings (as in not too aggressive on the pitch correction speed), because the way it will adjust pitch in real time will make random variations happen compared to the original track. It will create more of a realistic sense that it was a separate vocal take because the pitch will have variation over time compared to your main vocal line. Then after the pitch correction plug, you could insert a vocal transformer (or AU pitch plug in) to just slightly adjust the overall pitch by a couple of cents and maybe mess with the formants slightly as well, to get some light chorusing.
    If you want to spend some money, look at the latest Antares EVO plug ins, they make a whole range of plug ins specifically for doubling, tripling, or even creating a fake 'choir' out of a single line vocal. Might be worth a look.
    Otherwise, you could also just use the classic mix techniques for vocal thickening.. Make copies of the original to new tracks, then use a bit of delay (in the inspector) to slightly shift the timing. Then set up an aux strip with plug ins such as chorus or ensemble, that kind of thing.

  • 9.1.1 Time&Pitch Machine crash

    Running L9.1.1 on an iMac Core Duo w/Snow Leopard 10.6.2. With or w/o plugins loaded, Time&Pitch Machine crashes out to desktop when entering numbers from either keypad or alphanumeric keys. Deleted all plists w/o change in crash behavior. Also no change after creating Empty Project w/single audio track, mono or stereo. Can't find any reports of this crash in other forums. Otherwise 9.1.1 is stable. Thanks for thoughts on this possible bug.

    hmm I was fortunate not to have this in 8 or 9.0.2
    but this is a definite/repeatable bug in 9.1.1 which causes crash
    sample edit window
    then select time and pitch or any Factory menu items
    on exiting window or pressing screen set 1 key command crash happens evey time 1 track of audio no plugins
    cannot work with 9.1.1 as a result
    and you didnt fix screen set/display text only jumping window bug anyway, even when you said you had on release notes!!
    come on apple

  • Using the Time & Pitch Machine

    When I compared LE and LP, I noticed that LE has no pitch correction. After buying it I found that when opening up a track there is a Time & Pitch Machine. Can this be used for pitch correction? I was trying to mess with it today but my computer was not working properly so when I tried to play, no sound would come out. If I cut out individual words, could I then open that particular audio segment and adjust its pitch?

    Hi,
    LE does have the Enhance Pitch plugin, that I often use. It has 2 controls: how fast it responds, and what scale it uses (or chromatic). Works quite well! Much easier than the Time&Pitch machine or the Pitch Shifter plugin.
    The Vocal Transformer is fun, too, by the way. Great if you need a vocal from the opposite sex, and noone's available. Just sing it and shift the pitch up/down approprialtely.
    Regards,
    Jaap

  • My Wife got an iPhone at work. IT set it up the first time on another machine, they finally install iTunes on her machine but I don't know if she can sync without loosing Photos, SMS, and other things. She had six months of stuff on that phone?

    My Wife got an iPhone at work. IT set it up the first time on another machine, they finally install iTunes on her machine but I don't know if she can sync without loosing Photos, SMS, and other things. She had six months of stuff on that phone?
    The problem is she can't update to new software until she connect to iTunes, but she don't want to loose all that info.
    My question is:
    If she register her apple ID on that new computer, and sync the phone, will she loose everything? or iTunes will back up first (because apple id match) and then sync.
    Otherwise, how can I do it? The closest apple store is 3 hours away. thanks!

    Before you connect to a new PC, make sure that autosync is disabled in Edit/Preferences/Devices, otherwise her phone will be wiped during the following sync.
    If she has data on the phone she wants to save, back up manually:
    Disable autosync in iTunes, connect your phone to her new computer and right click on it in the device list and choose backup. iTunes will backup your phone without syncing. Transfer the purchases the same way, choosing "transfer purchases" this time.
    When you connect your phone for the first time, all media content will be erased. But you can restore your settings and app data from your manual backup afterwards.
    Don't forget to set up at least one contact and event on your new computer to be able to merge calendars and contacts when you sync the phone for the first time.

  • Time Machine question from an ex Windows user

    Simple question that sounds stupid but I just wanted to be sure. I'm new to Mac OS so bear with me on this
    Let's say I install a program and I want to be rid of completely or it causes some issues, if I use Time Machine to go back to before I installed it will all of the folders/directories that the program created be gone or will it just pull the icon?

    There is another way of using Time Machine that I don't think Camelot has mentioned. He is talking about using the in-system interface to flip back and forth in time and restoring individual files, but what you, metalrocker, originally asked was if you could go back to before you installed your program, and you can.
    First, a warning. Doing what I describe below will put your entire computer back the way it was before you installed the program you are having issues with. All documents, files, e-mails (if stored locally) will go back to what they were before. You can still get newer ones from your time machine, though.
    Second, the concept: Go find the DVDs that came with your computer. The first one is all you need, also called Mac OS X Install DVD. Put that into your computer. Now shut the computer down. When it starts back up, hold the C key pressed. This will make the computer start from the DVD. Starting up will be noticably slower from the DVD. You will eventually get a few questions about language, and you have to agree to a user license. Stop after that. You do NOT want to reinstall the operating system. Instead, look at the menu on the top of the screen. There should be one item called Utilities. On that menu, there should be an item called "Restore from Time Machine" or something similar. THAT function WILL bring your entire system back the way it was at a selected date and time.
    Normally this is only used if you messed something up really bad, or if you had computer problems on one machine so serious that you decided to switch to a new computer, but wanted all the stuff from your old one... from before the troubles began.
    Of course, this alternative is serious overkill if all you wanted was to remove a program. Most of the time, I just chuck the App icon out, and possibly take a look into your user Library/Application Support folder, to see if the application put anything in there, and if so, throw that out too.
    There IS yet another method - there IS such a thing as uninstalling a program. It is usually not necessary, and rarely recommended, but if anyone wants to hear more about it, and is a little handy with the Terminal, give me a shout.

  • Restore from time machine questions

    Since update from snow leopard to time machine mac mini runs very slow.  Too much beach ball.  I want to do a clean install of lion and restore from time machine and have multiple questions.
    1. I'm not sure if my time capsule password is the same as my airport, and if it is not where can I find it
    2. If I install the os can I just tell the time machine that I am migrating to a new machine and that would be the most simple and painless?  And if I did would that just restore broken extensions?
    3. Will my keychain be restored?
    4.What do I restore?  Documents?  All my files? Macintosh HD?  Applications?  Documents?
    5. I'm using parallels primarily to run the windows version of Quicken. Will time machine restore that or do need to reinstall parallels and windows etc?
    6. If I restore Applications folder will programs work or do I need to reinstall the programs?
    7. Do I install Ilife or Iwork?  Mobile me?  Widgets?  Printers, keyboard, etc?

  • I/O error in time-pitch machine!?!

    hello
    am using the time-pitch machine to speed up a stereo drum track (classic mode). the time-pitch machine keeps freezing after processing approx. half of the samples and then gives me an error message: I/O error, result code = -36?
    anybody got a clue?
    thx, monobeat

    yeah i've had these before. its probably a corrupt audio file. try saving it to a different location and then doing the processing. if it keeps cropping up on files from the same drive, start suspecting the drive.
    do drive maintenence stuff quick.
