Not enough gain level from line-in

Are you sure you are maxing out the recording line in volume and not the play line in volume?
 
I've just gotten into this very exciting area of PC recording. I have over 10,000 LP's in my collection and would like to create CD's for some favorites. I've begun using Goldwave with decent results and have burned a few CD's with my son's Plextor CD-RW. I've also familiarized myself with mp3 players such as Music Match Jukebox, Real Audio, etc.

When I installed a new soundcard two days ago (SB Live, Value)the gain level from line-in is very low, even with Windows line-in volume set to max. As a result, The volume level on the completed CD is rather low, requiring the playback amp volume to be set qute high to listen at reasonable levels.
This was not the case with my old card, a cheap unit installed on my A-Open system (P-233).

Has anyone experienced similiar problems. Any ideas would be greatly appreciated.
 
Thanks for the reply. Yes I've made sure of that already.

First off, I don't know if you're using a preamp for your turntable or just pluging the phono jacks directly into the soundcard.. If the latter, you should first run the turntable into a clean stereo receiver (w/ phono preamp) and send the tape out to your SBLive line-in.. Okay, assuming we're there:

You should be able to pretty much get a good level from the stereo and you'll want to adjust the line-in input so that the loudest peak on your record is under 0dB, -3 to -6dB to be safe. Once you record the songs onto your hard drive (use cooledit or some other .wav file recorder/editor) you'll have to save them as seperate wav files and fade the ends of the songs out (unless you want an album-long single track on your CD). That's the simple way if you're not concerned about making them as loud as most CDs and you can accept the pops in your original vinyl.

If this is not good enough, you can use the wav editor to remove the clicks and pops (cooledit does this pretty darn well), and then raise the volume of the files uniformly so that the highest peak of all the files is up near -0.5 dB or so (it'll take awhile to find the highest peaks but you can use cooledit's statistics function for any single wav). If you respect the recordings I wouldn't worry about using any compression to get the audio louder as you'll end up removing some dynamics intended to be there.

I hope this helps and doesn't add too much confusion.
 
Thanks for you reply, sorry it took me so long to respond (knee deep in tax stuff.

Everything comes from the amp (tape output) to the sound card line-in. In fact, now that I think about it, when I play my Hi-Fi, records always require me to use a much higher volume level than CD's to achieve the same level through the speakers. Your advice sounds like the way I need to go to make acceptable CD's. I don't want to use compression for the reason you indicated. I'll have to familiarize myself with CoolEdit
and the -0.5 type stuff to get what I'm looking for.

Thanks again.

Hello again,

I think this is the second time I've come across this post...?

But like I said last time, to get things up to the right level, normalize the recording _before_ chopping up the wave into seperate tracks (so you keep the same relative levels) but after removing clicks and pops. Normalization should be built in to most software and it 'raises the volume uniformly' up to 0 dB.

Oops, just found the other thread and you saw my advice already! Nevermind, hope it works,
