noise reduction for tv tuner recordings

[skyyblue]

i have a cheap tv tuner card (hauppauge win tv), when i record using windvr 3.0, i get this annoying fizzing background noise, how can i reduce it? my tv tuner card gets its audio from my soundcard, i have to put a line out into the line in on my sound card (which is built in on my mobo).

any suggestions or ideas will be much appreciated.

If you could post a screenshot of the video, you'll get a better answer. Open it in VirtualDubMod and go into Video-->Snapshot Source Frame. You may have to resize the picture smaller so you can post it here. Look at the directions below on how to post images.

hi,
audio or video noise?

[skyyblue]

hi, i believe it's audio noise, so i dont think taking a picture of the video will be relative. but perhaps im wrong. i will do it anyways just in case

i dunno if that'll help since the pic was resized up to about 85%, but i do strongly believe it is a audio noise, but i could be wrong since i dont know much about these things.

Hi, I am having the same problem with my video capturing. The video looks great, but I think the audio record volume might be too high, and I get like a buzzing sound when there are medium to loud noises. It's not too bad, but it gets on your nerves a bit after a while.
I have gone into the settings but the section where you can change the record volume has been greyed out (not selectable).
When I go to my volume in Windows, there isn't any control for Line In.
Can anyone help me?
I am using a 713x BDA Analog Capture Card which is a PCMCIA Card for my laptop. I have the A-V cords from my VCR, and have the Device set to the Composite Input.
I have already tried different cords, different shows, tapes, VCRs and all, but this problem happens only when you playback something that has been recorded, not when you just watch it. Please Help me.

You should put the audio ot yur TV or HI-FI t find out the noise is from the tuner or not. If it is not, then the noise is from the sound card.

When watching it on TV there isn't any buzzing. There also isn't any buzzing when you simply watch TV on the laptop through the card, or even while you watch your show while recording on the latop.
It only occurs when playing back the recorded show.
I'm fairly convinced the problem is that the recording volume is too high, but I can't find a way to reduce it.

There are two ways to lower the volume in windvr. Click on setup, then device and lower the record volume. Or you can double click on the volume icon in the task bar and select options, properties, then recording. Lower the volume for line in. This will lower recording for anything that uses the line in. Yo may also want to check either the bit rate or format for your audio record settings in windvr.

Thanks for the reply, but I'm still stuck. When I'm in WinDVR and I go to the Devices Tab, it won't let me select the Recording Volume. I think it just automatically takes the audio from my video capture card. Here is a pic of what I mean:-

[sainter54]

Also, when I go to the volume control, I can't select the device that I want (the capture card). Of the devices that I can select, neither has a Line In section. In the picture below, the lower section is of Realtek HD Audio output (my default laptop speakers), and the above section is of Realtek HD Audio input (my default laptop microphone). The Capture Card isn't listed. I am using the PAL DVD record settings, which are the best quality of the ones that are selectable. Surely there's something I can do????

I have tried to work on the problem by going into the device manager in Windows XP. I found the Card listed and entered the properties section. It even has a part that has Mixer properties. You can select whether the card can allow mixer properties, so I changed the setting to Yes, thinking that now it would appear as a device in my volume control. But it didn't work.
Any ideas?
Maybe is there another Video Capturing Program that might allow me to reduce the recording volume? I know WinDVR should let me do it, but it doesn't in this case.

[sainter54]

Does anyone know a way to allow the mixer properties for a device to be changeable?
I want to see if the mixer properties will allow me to reduce the line in volume, but the device isn't listed in the volume settings.

This buzzing you guys are referring to may be caused by an idling (active) input that is not being used for capture yet simultaneously recorded. Maybe I'm misreading the information but your Video input is 713BDA while audio device is Realtek. If you get the sound from 713BDA try muting some (or all) Realtek ports.

Audio card is no good. Laptop audio cards have historically had noise on them, all of mine have. Thank goodness I never need laptops for audio work.

Try installing any extra audio type programs you got with your laptop. Sometimes these have control programs that can access features not explicit elsewhere. ALso turn down your master volume and get a good set of headphones (sennheiser, Koss). Maybe you are hitting the headroom of the feeble onboard amplifier and speakers. Burn off some of your shows to DVD/vcd and check the audio quality on those, find out where the distortion/hiss is being introduced. Windvr can work well.

I burned some stuff to DVD, and you can only notice the crackling sound when you turn up the volume a fair bit. I suppose this doesn't really matter because all I want to do is convert some VHS tapes to DVD, and I'm never going to watch them with the TV Volume at full ball. Thanks anyway for your help guys.
