Click and Pops in Audio Playback

I am using a MOTU 824 Mk3 with L7P 7.2 and a Dual G5 tower. This system worked very well for quite awhile but recently there are click and pops in the audio on playback only, meaning the clicks are not in the actual audio files and they do not get recorded.
The clicks were occurring randomly, maybe 1 or 2 per minute. I increased the buffer size to the max of 1024, now the clicks occur every so often, maybe I'll hear 1 while listening to 10 minutes of audio.
I am not using L7 in demanding applications right now. Normally 1 stereo track with 2 or 3 plug-ins, though the number of plug-ins does not seem to matter. I could have no plug-ins running and still would hear the occasional click.
I don't think it is the MOTU interface because I do not have this problems with other programs. For example, if I run Waveburner playing back identical audio, Waveburner never clicks or pops.
Anyone have any ideas? It's starting to drive me crazy. It's possible this all started when updated from 7.1 to 7.2 but I do not know that for sure, it could have been happening before I upgraded.
Thanks in advance!!

I believe this problem is due to having the plug-in Soundflower from Cycling 74 active through an aggregate sound driver. When I changed the sound driver to another aggregate sound driver w/o Soundflower, thereby de-activating Soundflower, the problem seemed to go away. I need to do some more checking though to make sure it really is gone and it was Soundflower.

  • Clicks and Pops in Audio even with High Buffer Values

    Dear Community,
    I'm running into a problem with my Mac Pro 2008 for which I need urgent help.
    I have a Mac Pro 2008 which I use to do some audio production and mixing.
    I use 10.8 Mountain Lion for some time now, mainly with Avid Pro Tools 10 and Logic Pro 9.
    My audio interfaces of choice are the Echo Audio Audiofire 8 and an Eleven Rack (USB) which I never use simultaneously. For tracking guitars and bass I use the Eleven Rack but for mixing and adding other instruments I use the Echo Audio because of its multichannel capabilities.
    I had this configuration for many months / years without any kind of problem and being able to use very low buffer values (128, 64 and even 32 bits) with very low latency values (ideal for tracking guitar with software monitoring).
    Now I'm running with problems with audio clicks and pops in all audio streams independently of the audio interface I use.
    I've tried every tip I found on the web for optimizing my mac for audio with no success.
    Independently of the buffer I establish in Pro Tools or Logic (or any other audio software, for that matters) I always get the same harsh, distorted audio, with permanent clicks and pops. It's the same with pre-recorded audio or when using just an armed track with software monitoring. Even when using just Amplitube 3 in standalone mode, I can't get audio working correctly. Raising the audio buffer to 4096 (!!!) or lowering to 64 is the same. The output get garbled, distorted, harsh, with permanent clicks and pops (on the Audiofire or the Eleven Rack).
    I've already tried reinstalling drivers, mangled with all audio preferences possible with no success.
    I'm considering, as a final option, to reinstall the OS and all audio software from scratch but this is the very final possibility because of the long long hours needed to do so.
    Does anyone have some idea about this?
    Could anyone help me?
    Best Regards,
    Luis Mota

    Luis, the sound you're describing does not sound like a clock problem.
    Sync set to "Internal"
    To check you can go to Settings/Synchronization  uncheck "Auto Enable external sync".
    I'm guessing like most Mac users you have the operating system set to auto update, if so the system may have updated on it's own so you can't be sure you're running the same system that worked perfectly in the past.
    I disable every "auto" b.s. Apple/OSX tries to force on users... for pro audio users, it generally causes problems.
    Here's some things to try.
    1. Set the Mac's audio preferences to use only built-in audio for both recording and playback. Do so in both System preferences/sound and Audio-MIDI Setup.   Turn off the Mac, unplug and audio interface you have hooked up. Restart the Mac, Plug in an audio interfaces (doesn't matter which one) open Logic, go to Preferences Audio and select the installed interface, even if it's selected already, set buffer to 256.
    Any difference?
    2. Create a New User account and try running Logic from there.

  • Removing clicks and pops

    I see the manual makes reference to the program being able to remove clicks and pops in audio but I can't for the life of me find this option in any filters that came with the program.
    Can anyone tell me where to find this filter?
    Many thanks.

    drag the file onto your icon form your dock. soundtrack will open up, i think it might be in the actions tab on the left. try this out.

  • FCPX + Lion + Cannot handle AAC or Apple Lossless audio in H.264! (Clicks and Pops)

    This is a problem I've been having since I upgraded to Lion, and I've posted this response in other forums, but wanted to start a fresh one with a video I created of my findings. In a nutshell: FCPX in Lion cannot handle AAC audio in H.264 files since it will create audible clicks and pops when it subsequently renders the footage. This ***** because the iPhone 4 for example records as H.264 and AAC for the audio. Below are my findings:
    So I think I figured it out! (I'm pretty sure FCPX + Lion has issues with compressed audio formats, ESPECIALLY AAC and Apple Lossless!) There's a video of my findings below:
    1. I tried doing exactly the same thing I was trying to do on my machine on a co-worker's Snow Leopard MBP, and it worked out fine (it was just importing an iPhone 4 .mov and exporting it in FCPX). The output file was pretty much the same as what came in.
    2. I found out that only movies from my iPhone 4 were coming out all crazy in the audio, yet my Canon T2i files were fine. Both are H.264, yet the Canon T2i records audio as Linear PCM, while the iPhone 4 records audio as AAC.
    3. So I got an idea to use screen flow to record a youtube video and record the computer's audio. Then I decided to export with different formats, both as HD NTSC standards and as web standards with H.264.
    4. I found out that both NTSC and H.264 standards were perfectly fine, SO LONG AS THE AUDIO WAS LINEAR PCM (or uncompressed!).
    5. I then exported the same clip (both times as H.264) and ONLY changed how the audio was rendered (either Linear PCM/Uncompressed or AAC) and VOILA, I got click and pop artifacts ONLY in the AAC version. The ones that were output as uncompressed audio were totally fine!
    CONCLUSION:
    Final Cut Pro X on OS X Lion has issues with compressed audio, MAINLY AAC and Apple Lossless! Anything that is Linear PCM/Uncompressed should be fine! For example, MPEG 4 AAC Enhanced Low Delay at 320K came out 95% OK, one or two clicks.
    So if any of us are working with material where the audio came to us already as AAC (like an iPhone 4), then we have to rip the audio out somehow first (like through VLC for example) and import it separately as an uncompressed file.
    Here's a youtube video showing exactly what I'm talking about:
    http://www.youtube.com/watch?v=FDw4btShH0s
    Anybody else have any thoughts on this before Apple comes out with a fix?

    I was having the same problem and spent several hours on the phone with apple working with one of their 3rd level support guys. Their is deffinatley a issue with Lion and FCPX. I was told  they would escalate to a FCPX engineer and they would get back to me in two days. In the mean time I went to my local apple store and was able to recreate the issue on every machine I tried. Apple did call back and confirm that there is an issue with the way FCPX and Lion handle the import and export of AAC files. They said there would hopefully be fixed in a future update.
    The best work around I found is to take your AAC file and convert it to a WAV. I used compressor to do this and it seems to have solved the problem.

  • Strange Problem - iTunes audio clicks and pops when connected to internet

    Hello,
    I have a very strange problem.
    When I go to play a song in iTunes the audio clicks and pops. Not an uncommon problem I know, but here is where things seem to get strange.
    I'm using iTunes on a laptop so I have a little switch which allows me to turn off my wireless adapter thus disconnecting me from the internet.
    If I'm connected to the internet the audio clicks and pops but if I'm disconnected the audio plays smooth as it should.
    The problem arrived out of no where i.e. no changes made to the laptop like installing drivers or programs.
    I'm completely lost at what to do and after weeks of searching online I just had to ask to see if anyone here can help me.
    Thanks

    Since writing this article I read that there is a problem with the airport update for tiger 10.4.11, which is exactly what I'm running. This is a pretty serious issue because I can't even listen to streaming music off the internet (via my firebox) without major clicks and pops. I wish I turned my updater of when things were stable

    NONE OF THE ABOVE TOO IF Safari runs with the Firefox agent selected!
    So, it is not a MBOX2 PRO issue or a firewire cable issue or a thunderbolt adaptor issue.
    So it's Safari or Mavericks or ...

    Strange. Now the problem is inverted. If Quicktime is running alone, now I get some audio glitches no matter if I choose the aggregate device or the Saffire Le as audio interface. If I launch Logic, the audio is clean.
    (As usual all is fine if I use the built-in audio no matter waht sofwares are running)
    The problem is really inverted.
    The only way to get clean audio with Quicktime alone is to destroy the aggregate device!
    The good thing is that I have the control now. I can get rid of the audio glitches while running Logic.
    Oh an btw my firefox is 15.0.1.Latest version. Under Activity Monitor/Disk/Kind, it show Firefox 32 bits.

  • Audio Clicks and Pops appearing in clips

    In the final stages of editing a project that truly tests your machine, I am now running in to a mysterious problem.
    I am nearly completely finished with a semi-complex project. Just in recent hours, certain clips have started developing "Clicks" and "Pops" that are very, very distinct. This might be fine.... if I were able to correct them. But conveniently, it appears that Final Cut Pro X does not give you this capability.
    Is there a way to correct Clicks and Pops in FCPX? If not, is there some explainable reason why my audio is creating these problems slowly and surely? (the source media does not have the clicks)
    Thank you for your insight!

    I'm having the SAME EXACT ISSUE! Been driving me crazy! I had FCPX on SL, then upgraded to Lion a few days ago and it's been hit or miss with the renders. Some of them render properly, some clips sound fine inside FCPX and then render incorrectly, and some are fine until FCPX decides to analyze the clips and then it introduces all the clicks and pops which are then clearly audible inside of FCPX. I've done transcoding on clips that have come out OK in Compressor and they seem to come out fine. I'm not quite sure if there is any work around for those of us who have FCPX and Lion...
    P.S. A lot of people are talking about importing everything as .AIFF and all this stuff, well, how hard can it be to handle MP3s or Waves? I used Waves for all of the audio and they were perfectly fine until Lion, so this stuff about .AIFF just doesn't seem like a good solution. I'm going to try to create a random track and import stuff as .AIFF and other as .MP3 and .WAV and see what happens. It'd be curious to see if the cracks appear in some parts and not in others (for me they appear so long as there is audio, but stops in between the clips where i've put a 1 second silence)...

  • Upgraded to iTunes 6.0.5 sound now clicks and pops.

    I've been using iTunes 6 happily up until yeasterday when I was prompted to upgrade to 6.0.5. I did this and now the sound of all of my purchased music is like an old scratched vinyl LP. At regular intervals there are clicks and pops in the music.
    This did not happen until I upgraded. Strangely if I play the same tracks in QuickTime Player rather than in iTunes they pay without faults. I've tried changing settings to Safe Mode (waveOut only)and it makes no difference to the quality of the playback.
    So, is there any way to revert to the old iTunes installation or is there a fix for 6.0.5?
    FWIW, QuickTime Player isn't much of a solution since it doesn't support playlists.

    just checking. have you tried working through the other possibilities (apart from the QT sound out settings) from this document?

  • Sync, Corruption, Clicks and Pops

    Hello All,
    So I'm having multiple issues with my setup here as I'm preparing to go into a big film score and don't want to have these headaches once I start.
    First problem, and this might be the easiest to solve, is when playing back I'm getting intermittent clicks, pops, distortions from my sampled instruments. I'm running about 7 - 8 instances of Vienna Instruments, about 12 instances of exs with various samples/old Vienna Library, two instances of Stylus RMX, two instances of StormDrum (2-3 patches each) and one instance of Ethno. In addition to this I'm running my giga setup via lightpipe, and a Roland 5080 via Midi. I'm also running the movie, full length and DV quicktime format. I have all my audio samples on one external firewire Glyph Drive, the video on another external firewire Glyph drive, and the project on an internal (separate from the System Drive) hard drive.
    My initial idea was that these clicks and pops might be caused by a bottleneck on the sample drive. This drive I believe is running firwire 400. Are the amount of Samples I'm running too much for this drive? Would it help if I upgraded to firewire 800 or maybe got another internal drive running 10,000 rpms? Should I re-encode my movie so its not so hard on the drive bus but more processor intensive?
    My other idea was that it might be a case of bad Ram. Checking Logics System Performance window, I was only showing 75% on one processor and 30% on the second processor. So I opened up the activity monitor to check out how much ram was being used and it showed only 3.17 gigs of ram used. Going back to Logic all pandemonium broke loose with my project.
    Which brings me to my second problem...this project is having crazy sync sample rate issues. Everything is distorted and garbled being played back, Logic is returning an error sign saying that I'm not synced and showing a random sample rate (4168). Restarting my system and all the usual stuff (repairing disk permissions) helps not at all. Everything still sounds messed up. Removing the movie from the project lessens the distortion but the same sync error turns up. Opening up other projects, I don't run into these problems. I even opened the Autoload of this project and I didn't have this problem (other than the already mentioned clicks and pops).
    Is this project corrupted beyond retrieval? Do I have to manually copy everything to another project? Why did opening the Activity Monitor set this off?
    If you read through this long post and know any of these answers that would be awesome.
    Here's the specs on my setup.
    Dual 2Ghz G5
    4 GB DDR SDRAM (8 x 12)
    ATI Radeon 9600 Pro
    2 Glyph Drives
    Audio Sample Drive - 400mb/sec
    Video Drive - 800mb/sec
    Motu PCI - 2408 mk3
    GigaStudio PC
    Roland 5080
    TC Powercore
    Everything slaved to an Apogee Big Ben at 48.
    Thanks!
    Oh yeah Logic 7.2.1.
    Dual 2GHZ G5   Mac OS X (10.4.7)  
    G4 1.25 MDD   Mac OS X (10.4.3)  

    Hi,maybe this can help:
    In addition to this I'm running my giga setup via lightpipe,
    Going into what? Logic Pro thru the Motu 2408? into a digital mixer?It is not clear how you route this.If the Motu is the clock master,and you route everything through it,you should slave the Giga playback card to it,and make sure the Giga card can and is synced properly.
    My initial idea was that these clicks and pops might
    be caused by a bottleneck on the sample drive.
    Nope,highly unlikely. A bottleneck on a drive will only slow down a system.Unless you are using certain western Digital drives that shield their power and their FW grounds together...then the hum from the drive spining would be what you hear.
    My other idea was that it might be a case of bad Ram.
    Nope,highly unlikely either...you would simply have more crashes,and freezes.
    Which brings me to my second problem...this project
    is having crazy sync sample rate issues. Everything
    is distorted and garbled being played back, Logic is
    returning an error sign saying that I'm not synced
    and showing a random sample rate (4168).
    Sounds like you are not slaving the word clock correctly somewhere int he chain...but without knowing what sound card the Gigastudio is using,and how you have your word clock distributed,I can only offer the following:
    Remember to make ONE and only ONE device the sample rate clock master,and slave the rest to it.
    Please try to re-connect your word clock cables...and maybe even start by running only one device at a time,until you find the one that causes the problem.It might be a headache at first,but the only real way to troubleshoot this stuff is to go one by one piece of gear and find the bad one.Sometimes a bad word clock cable,bad power cord,bad grounding between devices,can cause all sorts of problems,including clocking issues.
    i hope this helps,
    Nick

  • Clicks and pops when putting footage in timeline, not in bin?

    I have some Mp3 audio to use for effects sound. Everything is good when i Play it from the bin, but as soon as I put in into the timeline it start to click even though it is not there from the beginning ?
    I have tried to send it to Sountrack Pro and analyze it. Soundtrack Pro does not find any clicks and pops????

    Do not use compressed audio in FCP. Convert the media to AIFF at the sample rate that matches your sequence.

  • Clicks and pops when running Mainstage 2 with Guitar Rig 5 in Mavericks.

    **I've read that this may be unsolvable but I hope someone can help me**
    Hello everyone,
    I very recently upgraded to the new Macbook Pro 15" Retina as my 2010 Macbook running Snow Leopard is on it's way to Apple heaven. This means I am now on Mavericks and **** is ******, it's my fault for not upgrading sooner so I am to blame in some respects. Here is my issue.
    My set up is fairly basic:
    Mainstage 2.2.2 (I can't upgrade to 3 as the synths we use are not 64bit compatible.. another nightmare due to my lack of upgrading in the past)
    Axiom 64 MIDI controller via USB
    Guitar Rig 5 controller via USB (audio interface)
    In Mainstage we have the L output for virtual instrument parts and the R output for guitar parts. These are globally panned L and R.
    The L output from Mainstage goes through the Guitar rig footcontroller out the L output through a DI and then to the mixing desk. The R output goes through the Guitar rig controller out the R output and straight to the guitar amp. Simple way to do both keys and guitar.
    We never had any problems with this in Snow Leopard. With Mavericks this setup is unusable due to the clicks and pops shooting through the guitar amp. It doesn't matter whether the voume on the guitar itself is turned up or down it's still all "click POP.. CLICK pop pop click" Mainstage just seems to be sending these pops regardless if anything is being played or not.
    When I ran the same session through my Focusrite Saffire Pro 24 there was no popping on the virtual instruments so I'm thinking it could be a guitar rig issue.
    Can anyone help me with this? I'm sure a lot of people are finding the same thing... **** I know a lot of people are getting the pops without guitar rig involved. For now I'm going to continue to use my old Macbook but I'd LOVE to have the new one running smoothly!
    Thanks a lot!

  • Analysis not working.. Clicks and Pops, etc.

    I'm trying to remove clicks and pops, clipped signals and power line hum from an audio track (registered using an iPod mic in a big room so it's full of noises) with the latest Soundtrack Pro 2-
    I did a Noise Reduction then applied the following Analysis: Clicks and Pops, Power Line Hum, Clipped Signal. After the processing, I click in each item in the list and fix it. The problem is that 90 per cent of the times the Click/Pop/Clipping is not fixed. I can see it alters the waveform but you hear pretty much the same thing as before...
    Do you have any experience on that?
    Thanks

    This is a tedious process you're trying to do. What it really comes down to is zooming out the audio until you have clicks and pops of about .5-1 sec. Then you really have to go over and over the really bad ones until you've covered it from all angles. What ultimately happens is you reveal layers of the pops. As you take out one layer another appears. When you isolate the problems they all begin to fix easier. The program is really very adept at finding the rest of a pop that only appeared partially on the surface at first.
    Good question - patients is a prereq. virtue here: Good Luck.

  • Clicks and pops with flex time and fades

    I am getting clicks and pops on tracks using flex time and fades. Any suggestions?
    Thanks

    Probably the simplest solution to this bug (it appears to not be creating zero crossed edits when creating a fade over flexed audio) is to cut the area to be faded into small region and render (or bounce in place) the small section, then fade it.

  • 'Clicks and Pops' using Flex Time?

    Has anyone experienced this?  Whenever I use Flex time on a vocal, I get clicks and pops, at very random places.  It happens more when the vocal is powerful, (although not overclipped),
    has anyone experienced something similar, and knows of a fix or a solution?
    thank you.

    Default Clicks and pops, audio dropouts
    I don't know if anyone else has this problem, but it's driving me crazy. I can't have any other program open while running soundtrack pro, even Activity Monitor, without getting clicks and pops and the occasional audio dropout. These issues are not present in the audio file -- they are digital artifacts that seem to only be an issue in STP.
    The multitrack project I'm using was created from a sequence in FCP, and when playing the original sequence in FCP, there were no audio problems.
    It doesn't appear to be an issue with my amount of RAM (2GB) because Activity Monitor was showing over 70% free. The processor (2.66 Intel Core Duo) doesn't look like it's being taxed all that much. Is there some kind of buffer setting that I should change? It's obnoxious. Every time I use some other application (Mail, Firefox, Acrobat reader etc.) I have to restart the computer before opening up Soundtrack again.
    Also, has anyone noticed that it takes a loooooong time to save a project?

    I notice quite a bit of issues with RAM as well. I just went up to 7 Gig to have some extra for the OS and my project just hit 3.7G of RAM which of course STP couldn't handle and it wont save and sometimes beach balls.
    So, I've split my project into two projects for now and will continue to do so even more if the memory footprint keeps increasing. There is some really poor memory management happening related to duplicate clips. Hopefully they are aware of it and do something OR figure out how to use 64-bit memory space like EXS in Logic.
