[Background: I’m on a kick to make digital copies of my entire vinyl collection, about 2,700 albums. I’ve already done about 700 CD’s. I’ve almost exclusively used Audacity over the past 3-years and am still working on it. I get as many 12 vinyl albums done per week, so it’s going to take a while
I keep the output from the process as VBR MP3, depending on the track, is circa 250kbps. I’m doing this so I can play my entire collection on random play by genre, year, artists etc. and create playlists of favorites. The MP3 files are stored on a NAS, backed up by another NAS, which is also backed up online. The music is streamed via a separate Logitech Media Server(LMS).]
Problem: I use a logitech media server to stream music to every room in my house. The vinyl albums/tracks I’ve recorded don’t play as loud as the CD tracks I’ve ripped. I’ve read about the recording levels in Audacity and pretty much follow the recommendations for levels. When I play back random tracks the CD tracks are always just a bit louder, no matter what type of music.
There seems to be a couple of solutions to this.
Use audacity AMPLIFY effect at the end of the editing to boost an album to as “loud” as possible. Easy enough on clean albums, but more time consuming on “noisy” albums. However, this doesn’t seem to still get the “loudness”.
Start using compression - all sorts of reasons I don’t want to. Not least it adds another layer of processing and issues.
Use the Squeezebox/LMS gain control to try to achieve a balanced loudness. It’s described here. http://wiki.slimdevices.com/index.php/Automatic_Volume_Adjustment
**Question:**Does Audacity set the gain volume adjustment metadata tags from your audio files?
Is there a good article that discusses the general issue of vinyl loudness vs CD loudness, or how best to achieve a balance?
