Random clicking sound

I've been doing some basic editing and I now have random low volume clicks on my soundtrack and I can't figure out how they got there or how to remove them.

If you're using MP3 audio, that's most likely the cause. FCP doesn't handle MP3 very well.

The solution is to convert your MP3 source file to 48kHz AIFF and edit with the AIFF files.

Hope this helps.

I Imported a DV video file and I'm trying to make some edits to video and audio. My skill level is pretty low, but the audio is clean before I begin editing and as I progress more and more of these random clicks show up. When I zoom all the way into the waveform they're less than a frame and show no consistent form. Very frustrating.I've never had this happen before.

This could be caused by audio that needs to be rendered. FCP puts a beep in the audio to tell you that it needs to be rendered. Go to Sequence, Render All and make sure everything has a check mark by it. Hope this helps.

The audio on the original dv file is fine. Looks like when I imported it the clicks were created. It's not the rendering process that's causing it. I downloaded sound soap pro, but when I tried to launch it, nothing happened. Still need to figure that out. Man...if you don't do this all the time, it's really a test of your patience.

I ran into this problem before when doing a Log and Capture of DV footage about a year ago.

One thing to try (and it sounds nuts) is to turn off audio preview in the clip settings of the Log and Capture window when capturing.

You'll need to find another way to monitor your audio when you do this... perhaps through headphones hooked up to the deck.

The other thing you should check is the sampling rate of your audio from the DV tape. If the DV audio is 32kHz you'll probably encounter problems working in a 48 kHz sequence. The easiest way to determine if it 32kHz off tape is to see how many audio channels are recorded on the tape. If all 4 channels have active audio, you're most likely dealing with 32kHz.

I think you can change your audio capture settings to convert the 32kHz to 48. It's been a while since I last did this.

I'm pretty sure one of the above solutions will work for you.

Good luck,

Bob

Do the clicks happen at edit points or within clips?

Clicks are random. Seems like they were generated by import process of dv file into FCP. After output as Quicktime then into Visual Hub then conversion to DVD, the clicks have disappeared or are do buried by the soundtrack/voiceover that you don't notice them.

I have similar problem. I have clicks at edit points of the audio clip. What it can be?

I have the same thing.

Slight differences in noise levels between 2 clips can cause a click at edit points. If you apply a 2 to 4 frame audio fade the click will go away. Some DAWs force an edit at "zero crossing" points. That's the point in the file where the audio waveform crosses zero. Edit there and no click. I don't know of any NLE that does that automatically. But, applying a fade smooths the transitional gain so no click.

When you do certain kinds of cuts it can result in a sliver of audio being created. When you zoom all the way in, you can see what looks like a single frame. That is the click. I think it happens when you try to drop in a new clip but instead of the new clip dropping between two clips it actually makes a cut in the tail or head of one of the clips leaving a sliver behind. I have not isolated what exact settings and workflow causes this. It may have to do with the fact that audio can be cut on a sub-farme level as compared to video. You should be able to delete the sliver.

Hi,

It's been a long time since you posted this issue and the reason I am reacting on it now is I am having the same problem in FCPX 10.1.4 as you did. My original footage is MTS and the audio sounds fine. It is only after importing it into FCPX random clicks occur. When I import the same footage into iMovie there is no problem. So the issue is definitively in FCPX>

I wonder, did you ever find a solution for it ?
