Line in recording

Tim S wrote on 9/1/2005, 6:42 PM
I have a microphone going through a mixer board which is wired to the computer's line in.

When I click on the red record button on the voice track it shows a recording a wav and the meters and waveform show a good strong signal. But when I play it back, the audio is too low.

If I plug a standard computer mic into the mic input and change the record source in windows to mic. It records and plays back fine.

Vegas shows the audio is recording and the playback meter shows a good signal, but its playback volume is too low.

Any tips to get a good recording in the line in.

Ran into a similar situation myself. The solution was a pre-amp line mixer (Eurorack MX602A). Otherwise the volume was unusable.

Of course you could always record directly into a DV camera, then download it--a less expensive solution.

Yep.

I'm going thorugh a full blown mixer with a pre amp output. It works fine if I record in the windows sound recorder.

Then I quit that and open MS and it shows a good audio level during both record and playback, but the audio is too low.

By any chance is the volume set low on the snd trck?

Additionally, I'm wondering if the recording volume controls are set right on his PC. That tripped me up recently. On my PC, I have to open the volume control dialog box and then click on the menu; Options|Properties, and then click on the "recording" button, to see the actual recording controls.
YMMV

Good point about the volume controls. Along those lines you might want to mute the other sound sources. I once worked on a machine where the owner had automatic notification when new email arrived. Right in the middle of the session there was this beep that new email arrived. Muting the PC took care of the problem.

If you select the recording input as Line In then any sounds the computer generates will not be recorded, unless of course the microphone picks it up.

That hasn't been my experience. Selecting line in does not automatically mute the other sources of audio.

Sorry guys, the line in volume was not it.

The key here is that when I record in MS/Vegas the record volume sound meter and playback meter both show good levels. But the playback volume is too low.

I don't change any setting and do a recording in the windows sound recorder and it plays back great. Nice loud volume.

Oh, i didn't say that it would mute the other audio. It means that the ONLY thing that will be recorded is sound coming from the line in jack. Any sounds the computer produces will only go to it's internal speaker or the audio out jacks; they will NOT be recorded through the line in channel. Now, whether that line in jack picks up beeps and such depends on whether you are using a mic and if the mic is in the same room as the computer and close enough to pick up the sounds the computer makes. Of course, you could always turn off the computer's speakers if this is the case. Then again, if the mic is close enough to the computer to pick up those sounds, it is also recording the fan and drive noises that the computer makes, and probably the sounds that you make while using the mouse.

Like I said, that hasn't been my experience.

Any idea why it record's fine (loud) in Windows Sound Recorder, and unusably low in Vegas?

Tim,

I suspect that the problem has to do with a setting somewhere in your system. Just as a matter of review here are the steps:

Right click on the little speaker in the system tray. Left click on Open Volume Controls.

When the panel opens on the menu bar select Options, then on the drop down menu select Properties.

In the Properties menu select Recording and scroll down the list and make sure Line In is checked, then click Okay.

With the Recording window open adjust the line input to max and that the mute is unchecked.

Now open MS and see if that has made a difference. If it doesn't open up Programs>Assecories>Entertainment>Recording. Use that program to test record. If it comes out okay and MS still doesn't record at a good level, then there has to be a setting within MS.

This leads me to believe that for whatever reason MS is not looking at your sound card. Do you have a mobo that has a built in sound card and also have a sound card installed? If so, this is where I'd suggest you start looking. If this isn't the case you might consider reinstalling MS. If you know how clean out the registery before reinstalling. If you haven't worked with the registry find someone who has and can show you how--please don't do this if you are not sure of what you are doing! You could completely dismantle your system and require a complete reinstall of the OS.

Still can't figure this out.

I tried to install Acid and had the same kind of problem. But with the acid installed, I had popping in the playback of audio in my Vegas so I uninstalled Acid and the popping went away in Vegas.

But still cannot get the linelevel recording to work right in Vegas. The record and playback meters both register fine, but the playback is extermemely low.

The wierd part is the waveforms look fine. It acts like it sould be playing back fine, but there is no audio there. Also when I save the file, and play it back in something else, there is no audio there.

I have not found out how to totally unistall either. ie remove from the registry.

Tim,

Are you using a Track FX? Are any plug-ins installed?

I think Sony should guide you through a complete uninstall. Phone them and have them walk you through it. It isn't difficult and as long as you export the existing RegEdit as backup it is usually possible to recover your system in a worse case scenario.

Is this a mobo sound card or one that you installed in a slot? Are you using the OS default sound drivers or did you install a program specific to your sound card? If you have installed a program that came with a sound card you might want to uninstall it. Reboot. Try recording. If this fails remove the sound card from the device manager. Reboot. Install the latest drivers from the manufactures web site (of course this means you need to download the drivers before starting any of this).

Because you are getting a wave form I still think that there is a setting either in the volume control panel or more likely a MS setting isn't right. The popping suggest a driver problem IMHO.

At this point you are trying to eliminate common system problems. It's going to be tough for anyone to know exactly what is causing this.

Thanks Storyman. Because of your help I got it fixed.

I have a 1/8 stereo to rca coming out of the back of my sound card (built in sound card). I was only using the left channel. When I plugged my regular speakers in, I noted my audio was working but only coming out of the right speaker.

So in effect I was not sending the audio back to my mixer where my head phones were plugged into. I switched it on the back of the PC to the right output and all is well.

Although it only goes to one speaker. I might look into getting some more Y cords to merge the two channels on the back of the PC. But at least I know what is going on .

Thanks for the help!

-Tim

Glad to see you found the solution. It must have been frustrating that it took so long.
