Good morning gentlemen. I have 16 songs for a CD of standards featuring my singing. Many of the backing tracks are commercially available tracks and a few were created with RealTracks. I'm trying to get a consistent level among all 16 songs, probably somewhere close to - 12 RMS. Sony sound forge Pro 11 also lets me find the loudness level and RMS. Does - 12 sound reasonable for final mastering? The songs are EQ and limited where I like them. Besides Sound Forge I also use sonar platinum producer. are there any tips tricks or plugins I should consider to try to get these tracks under control? There is not a huge variation I just don't want volume levels to change noticeably between tunes. Someone suggested tone booster loudness meter.
Thank you for any suggestions.
