Playback volume issues

In the process of starting to convert my vinyl into digital to add to my track collection for use in Traktor, using the following to capture the audio:
Turntable to Mixer to iMac 10.6.8 using Audacity 1.3.14
(This iMac is one that has an audio line-port so from that point of view it is simple. Throughout when I refer to playback volume its the volume achieved by the computers built-in speakers not use of amplifier and speakers at this stage)

I’m happy with the sound I’ve captured but when I compare it to WAV files I’ve purchased from places such as Junodownload the playback volume isn’t comparable at the high end ie. the same max level of sound isn’t achieved. I tried increasing the master volume on the mixer and lower the input volume and vice versa but everything I did made no difference as once I had adjusted to ensure no track clipping the end result was pretty much the same. When I export these files and add them to Traktor then play them the “Gain” adjusts to something like +4.6dB, I’ve seen some of my downloaded tracks adjust slightly but that seems like a big adjustment, I’m not sure if that makes a difference really but it seems unusual.

I’ve looked at some other threads for ideas, I tried amplifying the captured track but at max volume the track was loud but sore on the ears whereas the WAVs I’ve downloaded where just as loud but not sore to listen to (describing a feeling here but I think most people will know what I mean, maybe sore isn’t the correct word more like uncomfortable). I probably amplified it too much but I was just guessing as a trial.

Just looking for some more/different ideas or more importantly some direction as to how I can achieve the best possible sound before I start to work through my collection so far I’ve only done about 8 tracks from different 12" and EPs to get an idea, just don’t want to waste time pursuing the incorrect route. I don’t mind spending time to achieve the best results just not sure where to start.

Any thought and ideas will be gratefully received - thanks

Could this be the reason? http://en.wikipedia.org/wiki/Loudness_war

I’m guessing that you mean “perceived loudness” rather than actual loudness - many commercial recordings are engaged in a loudness war to make the CDs and on;ine recourdings to “sound” loud.

If this is the case than you need to use a compressor - Audacity has one of these, the best available is reckoned to be “Chris’s Dynamic Compressor” - see this page from the Audacity manual: http://wiki.audacityteam.org/wiki/Compressor#alternative

Also have a look at this workflow tutorial from the manual: http://manual.audacityteam.org/man/Sample_workflow_for_LP_digitization

Personally I never use any form of compression when I convert my vinyl as I prefer to retain the dynamic range that was put there ny the original recording engineers. I do Amplify/Normalize my final projects prior to export to -3.0 dB which is plenty loud enough.

Compression is most useful when you want to listen to stuff like opera (which has a very wide dynamic range) in the car , so you don’t have to keep fiddling with the volume knob all the time (that’s what Chris Capel designed his compressor for in the first place).

Guys, many thanks for super quick replies and the pointers to pertinent information, I will look into this.
