Last week I had interference from the mouse so changed it and keyboard and USB ports and added ferrite cores, lowered PC sensitivity to 60 and not 100. All was working great, all silent, then suddendly noise/distorted sound was recorded today.
If you have time to listen to the clip I would be most grateful – if not please see further notes below as FX may now be an issue and that is VEGAS or a setting

Is this a latency issue? My studio director said it is latency error

(I have put the sound clip on a non indexed page that shall be deleted in due course – I apologise it is on a web site but I did not know how else to let it be heard here as I do not have another web server).

NOW FX SELECTED BY DEFAULT – I noticed at the time that this fault started, when opening a new track/session I now (never before) have to select to record in MONO once I have armed the track. Why is this. It never happened before, it always opened ready to record in MONO

ALSO basic effects come into play that I have to de select so no fx are in circuit. Before, No FX was enabled at start up.

Deleting these FX and also increasing latency on the MIC CENTRANCE preamp seems to have resolved the issue but as it is intermittent my faith in the PC is zero Using the mic and preamp to another pc is perfect

I do not know why FX and stereo are now default opening settings
I do not know if this is a latency issue
It is intermittent so will have to use for shows and risk a re record until I find the issue Hence thanks for any advice

Thank you both very much for your replies and most valuable recommendation The product appears superb

Hi

It is all hovering about -39 dB ! Quite a change
I have changed the mouse and some seem nosier than others
So stayed with the new mouse and will try my preferred one once the clip on Ferrite cores arrive. But if the interference source is internal to the PC then of course they will not do much, I think – my electromagnetic theory is rusty and without a circuit diag of the pc who knows where this seepage is coming from, through etc

The question is now – how to make sure windows does not change the sensitivity setting when it wishes. I am going to put a link on the tool bar and keep an eye on it. Even de selecting all the advanced settings in control panel/sound I have one pc where I can see the slider moving as I speak! Ok I say, select all and give dedicated control to the app and it still slides!

[Peter Derek]

SOLVED
Well it works – Windows had wound up to 100 percent the mic sensitivity so by placing this down to say 60 percent it of course makes the internal circuits less sensitive. Now the mouse noise is so low, it is acceptable I should have checked this first. Strange, I have seen this before when win sound mgmt racks up the record input setting level

Thanks very much for your replies
I am using an external (USB) CENTRANCE mic preamp with input and output sound routed through it and internal sound card disabled

The mouse noise is -18DB and this is recorded on vegas even when it is in play mode. This is currently confusing me also! But clearly as you say there is seepage inside the PC

The same preamp and mic plugged into another laptop is fine and into a tower is fine. This is a fault condition that has arisen recently and I have changed nothing apart from Win OS patch/upgrades.

-18DB is loud enough to make the recordings non useable so I shall have to use another pc until I find the solution. Ferrite cores on the mouse lead may do something but I doubt it. There is something happening inside the PC. Remember the analogue days of crosstalk – well its digital ghost has returned! I shall try recording from vegas to an external HDD to see if that makes a change. Also adjust latency on preamp and may try a powered hub also.

Thank you very much for your reply

It seems new interface products now use the digital input so avoid the low pass filter that apparently exists in the analogue input but your link is a valuable fall back THANK YOU

The software question – I shall try to be clearer

…..§§§§§§§§§§………%§ § § § §§ §§%………§§§§§§§§§

If the above is a sound track in vegas
One can place the mouse over the two % above and highlight this area between the two % marks in the diagram above and see its timing
So if this is 3.5 seconds and it needs to be 3 one can take out some silences in this clip BUT one needs to know the timing between the % marks – as is visible with Vegas. Irig SW does not appear to show this timing nor any other mobile app so far.

This mail is to say thank you re your highly informative reply for a user questioning FCP v Vegas

In your reply you state vegas does not have a lot of templates for wizbang

I would be so grateful if you could expand on this – what kind of effects or templates do you find on other editors – what do they do/offer?

I use vegas and do wish to raise my variety of results – my videos are mainly talking head shots, interviews with cut aways to views, pans or stills

Many thanks

It is indoors in a hotel conference room
which will be empty, so may have some echo issues as few carpets
This interview will be mid way in the video and either side commentary from me recording in studio on an RODE NT1A

Can I use a recent motherboards (eg SANDY MOBO) in a tower PC that is circa 2000? (Dan PC with XP) I want to upgrade this old PC that has not been used for some time as it has a pro sound card in it with XLR in / Out, and run with Win 64 Ultimate and vegas

I am sorry for such a basic question but how do I check any new motherboard will be compatible? How do I ident the chassis to board plugs. Have the shapes changed? I presume power supply is compatible? The factory of this make shut some time back. I ordered the PC with an extra tall tower so it has space.

Vegas 7 works on it, it does of course take a long time to render and now I need to add FX, I expect it will really struggle. I will replace the HDD. Any comments most appreciated.

Many thanks
