Question

Fine Lines of Noise - Spectral Frequency Display

Hey guys,

I am hoping I can get a little help identifying some noise that is being introduced in an initial recording.

I record VO predominantly and in the last few recordings I have noticed some fine lines of noise in the spectral frequency display. The lines are only noticeable when zoomed right into the timeline. This noise is very sporadic and not in every recording nor is it throughout a recording it is usually just a specific sentence. In saying that when the sentence is recorded again the noise is not there.

As I have never seen this before I would like to know if someone has had this happen and what the cause may be. What would you suggest as troubleshooting steps.

I have had a little issue in the past with .WAV corruption but this seems like an altogether different issue.

Please see the attached screen shot.

Thanks for your time.

Liam

    If they were lines of actual 'noise', they'd show horizontally, not vertically. They look far more like mini bursts of interference of some kind, or caused by a minor overload. Can you zoom in one and show a screenshot of that, and can you provide a small audio sample?

    Hi Steve,

    Thanks for your reply. I have zoomed into the area of noise (please let me know if far enough) please see below.

    What is the best way to upload a sound file to here?

    Thanks

    Liam

    Thanks Steve,

    Apologies for the late reply I forgot it was Easter! I was initially looking for somewhere to attach it via the forum and completely didn't consider dropbox.

    The link below is for google drive (I don't have DB).

    RAW_Interference.wav - Google Drive 

    Please let me know that it works.

    Thanks

    Liam


    Yes it works fine, and it's certainly a little weird. I've heard similar noises to this come from a faulty microphone...

    So just as an initial experiment, can you try a recording with the same chain of equipment, and a different mic?
