'Bump' noise in Adobe Audition

[lesh84817475]

I have a question which I would appreciate assistance on.

When I record my voice over in Audition, after I do my noise removal when I listen back, there occurs a strange occasional 'bump'  noise at one or two random places in the recording. Has anyone else experienced this and can you offer an explanation?

Can't comment on this at all without hearing one of these 'bumps'. For all we know, it could be you kicking the mic stand!

Hi Steve,

Its definitely not me kicking the mic stand, the noises are quite random, and I am definitely not expert enough to fix or work out why they occur... Is there anyway I can send you a sample file?

The easiest way to listen to files like this here is for you to put it into something like Dropbox, right-click on it to get its public link, and post that on the forum.

Ok thanks Steve

Let me know if this works and thanks if you have a few seconds to listen and let me know what you think

Yes it works fine. Yes I've listened to it, and because of the timing of these bumps, they don't appear to be directly related to the actual audio. But, you've sent us an MP3, and MP3 encoding is anything but perfect - all sorts of things can happen. Can you record a short sequence as a wav file (essentially uncompressed, so no encoding), and if it still happens, submit that the same way, please?

Thanks very much Steve for listening to the file. I will send a wav file in the morning. Are you perhaps saying that because wav formats are better quality I should record in that format wherever possible? The issue of course is that a lot of auditions require mp3 formatted files. I'm going to bed now but thanks again for your time.

The situation is very simple; MP3 is only a distribution format, and was never intended to be for production purposes. The idea is that you record and edit everything in uncompressed wav format, and when you do a final distribution copy, you use 'save as' to create a separate file just for this purpose. It also means that if you want or need to send something out in a different format for any reason, you've still got the uncompressed master to go back to. The problem with MP3 is that every time you open the file, you have to decode it - and if you subsequently re-encode it, the quality drops dramatically, and this is progressive. With uncompressed wav files, none of this happens.

Great advice Steve thank you. I will record and edit a sample in wav format, convert to MP3 and will let you know how it goes.

Hi Les,

I understand that you were experiencing issues with unwanted noise in your project, but as we haven't heard back from you for quite some time now so I wanted to check the status of your issue.

In case if it hasn't been fixed yet please let us know and I will be glad to assist you.

Thanks,
