Audio pops/clicks and optimum setup

I've recently begun to use CC to create small video's which will be posted either to YouTube or FB. These are NOT for commercial purposes. I also incorporate audio music into the videos. I use ProTools to create high quality WAV files which I then import into my video project as audio. I'm finding that there are clicks and pops when playing back in CC. This is "before" any rendering. And, of course, it also appears post rendering as well. I wanted to know if anyone could recommend the optimum setup, editing and rendering. My most recent project which incorporate some imagery uses 25" w x 15" tall at 240dpi using TIFF's. Since YT and FB compress, I'm using 1280x720 when I render. Any optimum setup recommendation?

And what audio files? This sounds like you are simply hoplessly overdoing it and use excessive sample and/or bit depth rates that PS is less than able to deal with properly... And DPI and realworld units are irrelevant for video. Only absolute pixels matter.

Audio pops/clicks when changing angles in multicam clips

I am having problems with audio pops/clicks when working with angle switching in multicam clips. it always occurs when i utilize any of the "audio enhancements" features, such as the loudness or background noise removal features. Switching angles results in audible audio pops. The only way to get rid of them is to disable the audio enhancements. This occurs regardless of the audio source. Is this a known bug that is being addressed? I rely heavily on the audio editing features in my work and am hoping this will be resolved in an update soon. Thanks for any help-

Hi Brad, thanks for the reply!
That sounds like a good workaround. What I have been doing in the meantime is create a new compound clip after I finish all of my cuts, and then apply the audio edits to the new contiguous audio clip in the compound clip.
What is really strange and frustrating is that all of my new audio bugginess really began when I could no longer detach audio from my multicam clips in 10.0.9... After doing many searches here, it seems that in this most recent update of FCPX this is no longer a 'feature'... I don't know why they changed this, but in older updates of FCPX you could detach audio from original clips, compound clips, or multicam clips with no problems. I would routinely create and edit all of the angle cuts in my multicam clips in the timeline, and then if I wanted to, be able to detach the audio and do more edits if needed. Thankfully I can still apply edits to compound audio clips, but it would sure be nice if I could just correct/enhance audio without ugly-sounding artifacts in multicam edits. Thanks again-

[VIA] KT4Ultra - Sounds Pop, Click and Stall

Hey folks -
I hope someone can help here. I am running a KT4 Ultra with an Athlon 1800 MHz chip, all of the latest drivers, and sound files are driving me nuts! The audio clicks and pops and "stalls" for miniscule amounts of time while playing. It is especially noticeable when playing a video/DVD, as eventually the stalls add up to a multi-second delay between video and audio. It is really frustrating watching a movie and having the characters move their mouths, only to hear their words during the next scene!
I REALLY don't know what could be causing this, but it is driving me nuts. I am using the C-Media 8738MX chips on the board for my audio. Should I purchase a separate sound board, or do I need to change some sort of settings?
Thanks very much in advance.
Garry Wakely

For a while I tried to use that integrated C-Media, but it just didn't work. I'm not sure is the chip piece of s*it or are the drivers just bad, but I suffered from great number of blue screens (1-2 per day) in games. Some times it also caused crashes when Windows (98SE, this happened 2002) was loading. This drove me almost insane, but luckily I eventually found out that C-media was to blame. I purchased Philips Audigy Edge, and everything has been working perfectly since.

How to fix streaming audio pops/crackles and then stops all sound

I am a google Chrome user. I am unsure if this problem is related to Chrome or to Flash by I suspect there is a problem with both. I previously had this problem where when you start a youtube video for example the audio would pop/crack and then the audio would go dead. If you were able to put the video on full screen before this happened it would work fine. This really only happens with windowed (non-fullscreen videos). Previously I went in to my chrome plugins and disabled chrome's native flash and that fixed the issue. With the most recent update to Chrome this has happened again. This time disabling chrome's flash does not work. On the adobe version site it says that for chrome the version should be 11.5.31.137 but it shows me as using 11.5.502.146. The latter would be the version for firefox. I do not use firefox. Could this be causing my trouble? I have used the official flash uninstaller and restarted my computer and reinstalled but the same thing happened. Thanks.

Thanks for the link. I have tried what they recommend. I currently have two flash files. I have disabled the chrome one and the one that is enabled is C:\Windows\system32\Macromed\Flash\NPSWF32_11_5_502_146.dll
However, I ran the chrome://flash and this is what I got:
Flash plugin

I've never looked at this before but it is weird that it is saying that that flash is not used.
Anyone know about the firefox version of flash installing for Chrome because as I described above that doesn't seem right.

Audio with clicks and clucks

Hello, I have THL W200S (MTK6592 with 1GB RAM) with stock 4.2.2 ROM. When i start a call i hear sound and voice with strange clicks and clucks (like if the process is too heavy for the hardware to handle it) but if i switch to loudspeaker or headphones everything is ok. My wife has THL W100 (MTK6589 with 1GB RAM) with stock 4.2.1 ROM and she has no such problem.

I tested it on my second phone Alcatel One touch Pop C1 (MTK6572 with 512MB RAM) and there is no such problem.

Pops, Clicks and Hisses : Updated to 10.5.7 (audio example)

I updated to 10.5.7 and now when I open a GB file I hear this : http://bit.ly/9Wigq
As you can hear in the example, it appears even when there is no audio present. It's different every time, and affects recordings as well as exports.
Here's my set-up
MacBook Pro : Updated to 10.5.7, 3 gigs of RAM.
M-Audio Fast Track Pro : Updated drivers
Wacom Cintiq 12WX
I haven't tried without the Wacom attached, although I can't see why that would affect audio.
Any thoughts gang?

Turne dout it was T-RackS causing the issue.

Audio Pop/Clicks, then completely drops out

This just started happening to me completely throws a wrench in my workflow.
I'm watching lectures using VLC. I pause the video, take some notes, then click play and hear a pop or a click. then no audio. this renders my whole soundcard useless ie no audio output from any application. My current fix is to restart my machine, but considering I have a few other applications open to take notes, it really is a hindrance.
any suggestions? or do i have to take this thing to my local genius bar?

Update: When detaching the audio, this problem goes away. However, the audio fade-ins from transitions, etc. go away. Is there any way to solve this problem without detaching?

Audio pops/clicks when using external speakers

Here's the problem -- When my Mac plays a sound and it had not played any sounds for a while, it always pops (or clicks, same thing, just a matter of magnitude). There is no pop if there was sound recently, like in the last 3 minutes or so.
My iMac is an aluminum 20" model purchased in May 2008. I have external speakers playing audio. I don't think the pop happens when it's just the internal speakers.
Is there an audio driver update? The Software Update menu doesn't find anything newer to install for me. The pop is very irritating and I consider this Mac to be broken with respect to audio output.

Finally, a workaround. From another thread I learned that this is an old issue. The Mac shuts off the audio output electronics after some period of inactivity. When it reactivates, an audible pop happens. It's an old issue that Apple for some stupid reason doesn't care to solve. For a company that espouses fluid, integrated user experience, it is incredible that Apple could allow such a glaring audio defect to persist through so many generations of products. Surely they must realize many users will be connecting external amplified speaker systems to the analog audio out port. Doesn't anyone at Apple test the computers against the variety of input loads the audio output circuitry will be interfaced to? I understand that Apple has no control over the variety input impedances and DC biases their audio output electronics will see. But I think the popping could be avoided if they just employed a simpler scheme where the audio electronics do shut off. They are too smart for their own good.
That said, the hack that is so far working for me is this freeware utility KeepSoundAwake that plays an inaudible sound periodically. I would much rather see a solution in the firmware.

Pops & clicks, and i read the forum already

I tried everything in the forum so far and still have the pops a clicks. how do i get rid of them? this all started after i installed my new asus a8v motherboard and amd64 chip. i am only running in 32 bit though.

I have a Sound Blaster Audigy 2 Platinum, Model SB0240P, on mobo Asus A7V880, cpu AMD Athlon Xp 2400+, 52 MB RAM DDR 333Mhz, HD Quantum Fireball p AS20,5, HD Maxtor 60GB, DVDRAM LG GSA463B, DVDROM LG 860b, vga Ati Radeon Sapphire 9000 pro 28mbDDR, tvcard Pinnacle PCTV, modem 56k Atlantis, spk Creative inspire 6700 6..
The problem apeeared when i changed my mobo. Before of this asus, I had an ECS <SPAN class=text_26boldblue>K7VTA3 (3.
) and on it audio was ok!

Pops clicks and hesitations

Problem seen when streaming from the internet (e.g. BBC iPlayer Radio or YouTube Videos)
Windows XP SP3
Adobe Flash Player 11.5.31.5
Browser Google Chrome (but fault is also present with Internet Explorer)
This PC connected directly to router via ethernet cable.
Another Windows XP laptop sharing the same internet connection via WiFi also shows the fault.
A windows 7 PC and an Android phone sharing the same internet connection do not show the fault.
The common factors seem to be Windows XP and Adobe flash player.
I have tried disabling startups and services in MSCONFIG with no effect.
I don't see anything using lots of CPU in Windows Task Manager.
Advice on what might be the cause of the fault and how I can investigate/fix it would be welcome.
Thanks,
John

Hi John, wish I had a solution for you, instead I am just adding to the problems list. I figure the more info the community sees the better chance to fix the issues.
I too am running two computers XP sp3, Flash 11.5.31.5. My laptop has shown the fault on two different wifi systems, one being the same as my desktop. I have also noticed the symptoms on amazon streaming as well as the seussville.com kids website. This is what led me back to flash thinking it could be the issue. Clearly my son was none too happy about that!!
If I happen across a fix I will certainly reply again. Thanks!

How to remove/minimze audio "pop" or "click"

Using FCP 4.5
I have an audio pop/click within a clip and have been unable to figure a way to remove it or at least minimize it. I can see it in the viewer when the wave form is displayed Any suggestions will be appreciated.
Ron

Randy,
Thank you for the suggested approaches...since it is a split second pop...and dialogue is not an issue, I think I will go with cutting and pasting. I have Soundsoap...but haven't used it much...but I may experiment once I finish this project.
I was hoping there was some kind of (simple) audio filter in FCP that would limit the pop...but apparently there isn't, at least not one that I could find.
Anyway, thanks again for your help...I'm off to cut, copy and paste.

How do I eliminate clicking and popping in .wav sounds?

I tried importing a .wav file for background music in my Director movie. The .wav file is about 3 minutes long, and when I publish a projector I hear incessant clicking, popping, and skipping. What's the best way around this? Thanks in advance.
[EDIT] Just now I tried substituting an .mp3 for a .wav -- it made no difference; popping, clicking, and skipping were still there.

Clicks and Popps in FCE

Hello,
I just started with FCE 3.5. My first project is a iMovie project I started in iMovie and now imported into FCE.
Here is my problem. After adding clips from the browser to the timeline and rendering it the audio makes clicks and pops (I don't now how to explain it best). I don't have the problem with the same clips in iMovie.
Any advice?
Thanks and regards
Andy

Hi,
I have no mp3 in the project. The files with the problems are the movie clips. And you are right. iMovie is just great. I get the feeling much better then FCE. Its much more difficult to only achieve the same results then in iMovie. If I just look at the great themes I have in iMovie. I have only switched to FCE because my project last around 90 minutes and iMovie wasn't able to handle it (not this project - the one before) FCE very poorly imports iMovie projects. It doesn't import any transitions and "forgets" half of the timeline.
Thanks for your feedback

Lots of audio pops when recording from mixer

I'm using FCP 5.1.4 on a mac laptop (don't know what type it is, but think it's somewhat recent). I'm recording a stage play's audio.
Here's my audio flow:
Mixer's 1/4" headphone jack -> 1/4" Stereo audio cable -> 1/8" stereo adapter at other end (have also tried 1/8" mono) -> Laptop's microphone port (no other input audio port available)
I can get a good signal, but there's constant audio pops/clicks happening at a steady rate. I remember reading somewhere else that problems can arise when recording directly from a mixer due to the high signal strength coming from it. Any ideas why this is happening? How do I fix this?

Phillip Roh wrote:
What is a mic bus level output?
Most better mixers have direct bus ins and outs. Just like plugging in a mic.
Laptop doesn't have a line in port
Get a different computer if you're expecting to enjoy doing audio capture.
If i used the RCA or XLR output jacks, would the popping still occur?
Irrelevant, it's all about signal type, resistance, milliamperes, millivolts and milliwatts. Not connectors. You can put an XLR on your power supply and it wouldn't change the voltage.
I think my workplace may have a few USB audio things lying around. Like it has 2 XLR input ports, then connects to computer through USB. Do you know if they tend to need certain software, or if they're plug and play?< </div>
Unknown from here. this is not a FCP question.

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.
