Terrible 'Tape Hiss' sound although recorded properly

Thomas-Monks wrote on 12/18/2022, 3:37 AM

Hi Folks,

Vegas 19 / NEW PC 16GB ram / WIN 11 64bit / Sony AX-700 Camera shooting 4K /30 (Deliver 1080p /30)

Here's the deal, Did a sound check (patched directly into the board), played it back and sounded good. Get home, excited to edit the show.. and heart attack time, it sounds like I recorded it at -34dB on a cassette, then pumped through concert mains. Ok, Ok...I plugged in my headset and THANK GOD it sounded normal. I then played it on my media player, same garbage as when I try to edit in Vegas 19 !

So, I figured it is the computer codecs.

ALSO, It's not stage lighting, but still... with my 1" sensor (running full auto camera) I wouldn't think that it would have so much noise. It seems the Vegas editor noise is worse than what you are looking at straight from the camera. I do have REDUCE NOISE v5. Perhaps a codec can help here ? I've attached the XML FILE here as well.

Can you guys help my get these in my system ? Thanks, Tom Monks.

@Thomas-Monks  ... It would be very helpful if you could provide a detailed MediaInfo report (it's a free app) about the media from your camera - the current info that you've provided doesn't provide much info about the audio.

Also, it would be great if you could provide a detailed rundown of your computer's specs added to your 'signature' (see mine as well as that of many others on the forum). In your post, all you say about your computer is that it is new - but is it a Celeron, an i3, i5 or i7? BTW, you RAM is below the recommended minimum for 4K editing - https://www.vegascreativesoftware.com/us/specifications/#productMenu - it was the same for Vegas Pro 19 other than only the last few builds had Windows 11 official support.

And also again, are you using any int or ext sound card other than the computer's inbuilt sound card?

That isn't hiss, that is a squeal... a high pitched frequency. Can you upload the original audio file so I can do some tests on it? The good news is, the squeal seems pretty isolated to a certain really high pitched frequency, so it may be possible to remove it mostly without doing too much damage to the rest of the audio.

+11

It does not sound too bad on my PB systems. Maybe something ain't right with your player or playback system. Otherwise, the noise spikes I see @ 6 and 12kHz (and can hear at high SPLs) can be attenuated with noise reduction and/or a notch filter.

On my cheap speakers, it sounds like hiss with a high frequency buzz like maybe fluorescent lights or similar.

Thank you all...it was a codec / driver.

Interesting behavior, I haven't seen an audio driver malfunction like that before.

Asus sent Microsoft the WRONG AMD video card drivers and completely created havoc with chroma values. I think the audio problem is also with MS update. I've disabled auto updates from MS, reinstalled audio drivers from AMD. Problem solved.
