Here is an excerpt of the video, in which you can here the cracking sound that I am talking about.

The cracking sound is part of the video, as it can be heard on other computers as well (as you will notice when opening the attached video). It is not part of the .wav audio track though, which I created with Movie Edit Pro as well.

I exported the video again with 192 bitrate audio, and the problem occurs much less, not all all in the first 30 secs, but then a lot again afterwards. Is there a way to set it even higher, or should I have selected a higher bit rate when recording the audio?

Hi

The unwanted noise is definitely not overload distortion - it is interference coming from somewhere, either inside the computer or external.

Does the video have sound attached to it ?  If so try removing the video's audio and re-recorded your narration.

Did you have a mobile phone or another source of electrical interference near the computer when you were recording the audio?

No, there was no mobile phone close by when recording the sound, just my laptop. As mentioned, there is no unwanted noise in the .wav audio track. And the video does not have sound, recorded in OBS with sound disabled.

I just notice that there is also unwanted noise when previewing in Movie Edit Pro. It is a bit sharper though compated to the video, and on other moments. Can this be some sound driver problem or so?

Now I've had chance to hear the audio I entirely agree with JohnEB: it is not overload distortion.

But I have heard that type of noise before and it is almost always associated with a problem with the soundcard's driver or its buffer.

However, given you are clearly using the internal audio of your computer this is baffling, to say the least.  Can you check with the manufacturer of the internal audio (most often realtek, I think) that the drivers are up-to-date?

To what format (wav, mp3, etc.) are you recording the narration?  I know you mentioned bit rate in your original post but that didn't really tell us the format.  The mentioned numbers should be more than adequate for mp3 but would be very low for wav.

One other, slightly "off the wall" thought: is the computer you use for export a laptop?  Is it running on batteries or via an external power supply whilst exporting?  If on external power could there be a problem with that power supply such that it creates "spikes" at random intervals?

EDIT: you posted your reply whilst I was typing.  The additional information you've given seems to reinforce the idea of a possible driver and/or power problem.

I know this is a little older post but I was just wondering what the verdict was, and if it was fixed? Because I'm getting the same thing my playback of my video is fine but when I import it to Magixs I get random loud spikes every so often....any help??

Hi eaststreetgaming, welcome to the forums.

Have you read through the various points made and questions asked in the earlier posts to this thread? If so, have you tried any of the ideas offered to solve the problem, with what result?

Also, please read https://www.magix.info/uk/forum/please-do-the-following-before-posting-your-question--621831/ and give us the information requested there.

I apologize I missed one part to that and it fixed it at least for future problems! Thanks! For me it was the audio bit rate was to low I had mine on 160, and I moved it up to 320 and it worked perfectly

Sorry for necroing this thread but I have exactly---and I mean exactly---the same type of crackling sound.

Yes, I've read the entire thread. No, there was no outside interference. The problem is with Nvidia Shadowplay. If I record with OBS, the sound is perfectly fine. However, in Shadowplay I've set the bitrate to 50Mbps (the default) while in OBS, I've set it to 25Mbps. (So the fact that OBS works perfectly well in the audio department with Magix points that it's not my environs or my electronics that's the problem.)

The problem now is that lately, every time I open up OBS, it causes screen tearing (and yes, I've Vsync and Triple Buffering on; in-game and on the control panel and simultaneously---I've tried every combination) so now I'm left with just Shadowplay, which doesn't cause the odd tearing. Video now works fine. It's just the audio that's bothering me. Magix Movie Edit Pro 2015 Plus and Shadowplay do not seem to like each other.

I'll lower the bitrate later and report here if whether the bug disappears.

My specs:

i5-6600
Nvidia GTX 1060 Dual 6GB
Asus H170 Gaming Pro (with the latest Realtek audio driver)
8 GB RAM
Windows 7 64-bit

Hi

. . . . It's just the audio that's bothering me. Magix Movie Edit Pro 2015 Plus and Shadowplay do not seem to like each other. . . . .

Did you not try the OP's solution - set the audio bitrate to at least 192 kbs and sample rate to 48kHz in Shadowplay if possible (44.1kHz will do at a pinch).

The alternative would be to run the video through a converter to up the bitrate and sampling rate to the above values.

Hello John. I just got back from work.

I'm afraid that's not possible. Shadowplay's settings are very limited. (Please see the attached screenshot labeled "Shadowplay Settings.")

I'm trying out exporting the audio file in Magix as an MP3 file and see if it does not come up with a messed up result.

UPDATE: No luck. :( Cranked it up to 320. I still got the crackling sounds. I wonder if fiddling with these settings will fix it?

@IMBACORE

It does sound like a buffer problem to me rather than a bit rate problem.

In MEP, go to File / Settings / Program, find Playback and first try switching audio drivers. You should have the choice of either Wave Driver or Direct Sound. If changing the driver doesn't cure the problem then try increasing the number of Audio buffers.

Thanks for the suggestion CubeAce.

It's set to "Wave Driver." If changing to Direct Sound doesn't fix it, what's a good audio buffer number?

 

@IMBACORE

The box only allows you to go up to 9 anyway. It won't harm to try that first, but if it causes other problems then lower the amount of buffers until you acheive a performance balance. Weirdly you have an extra option in your Image Playback box that I don't have, which is 'Change footage dimensions in high quality (slower)'.

I wonder why that has disappeared in the newer version of MEP?

No idea as I only have the 2015 version. :(

So increasing the number of buffers = harder on your PC's resources?

@IMBACORE

Any increase in any configuration would be an increase on a machine's resources but sometimes it's a trade-off that works without serious consequences or a loss of performance where it's acceptable or least noticeable.

My question may be answered by another member who has owned both versions.

Older versions of some programs sometimes have to be run in compatibility mode to work well on newer operating systems. Either because they can't cope with newer screen resolutions or processor speeds or are now working in a 64-bit operating system whereas before they were working with a 32-bit operating system. Sometimes it's hard to pin down what causes particular problems.

That is why it is preferable to give as much information as possible as to regard to PC specs, operating system, programs involved, including which versions and project type.

Setting the buffer to 9 seems to have largely solved the problem although I still managed to catch one instance where the audio glitched up for a second like that in the OP's video.

I've already mentioned my specs:

"My specs:
i5-6600
Nvidia GTX 1060 Dual 6GB
Asus H170 Gaming Pro (with the latest Realtek audio driver)
8 GB RAM
Windows 7 64-bit"

Additional info:

- I'm using Razer Synapse with the Razer Seiren microphone and Razer Surround installed
- The glitch is not present in the recorded video; only when you load it to Magix.
- The glitch occurs even before exporting. Instances of it show up on the wave form as vertical narrow bars.
- Using OBS with Magix Movie Edit Pro does NOT replicate this glitch. Only with Shadowplay (and I can't use OBS with this particular game as it bugs out).
- I've solved this problem by using Handbrake to render the video as two files: one containing my voice and the other the ingame audio. I'm using the DTS-HD passthru feature when doing this. I then separate the audio files using Magix. I encounter no problem using this approach but it's such a roundabout solution that a fix would be appreciated.

So, points of interest:

- Magix does NOT have any problems with OBS, only recordings by Nvidia Shadowplay

- The glitch occurs even before exporting.

- Audio produced by Handbrake do not cause any problems with Magix too.
