Something I've never really considered in all my years recording is wrapped around these new 'requirements' for the streaming platforms - LUFS. Our work has shifted from 100% CD distribution to now 65% downloads - and luckily our music is not really Spotify or iTunes delivery friendly, as it's for a specific context and has text that goes with it explaining features. It's essentially music for ballet. Music that fits the requirements of an exam - so it has carefully controlled features. Not mainstream music at all. Historically piano, with a real pianist, but now more commonly where pianists are short, recorded piano. Some are arranged tracks - and much is quite traditional orchestral style, with a few heading towards big bands or effects. No electric guitars, no distortion or big drum kits - think old fashioned, not contemporary. The tracks are always played in rectangular spaces with all hard floors and walls - mirrors and glass, so they're lively spaces, which means any effects, even reverb can make it into a mess unless very gentle. We even take our pre-masters into these spaces and check them there to make sure. Loudness wise, we have tracks that would fall into a few 'volume' boxes. Loud, modest and gentle would sum this up, but we cannot stray too much in loudness becaue turning up and down the volume is often tricky to do. The standard we've always used means that in Cubase and Sound Forge we would consider -5.1dB on the meter to be loud, with a gentle track running in at -10.9dB. The middle ground tracks usually fall at around -7 to -8dB. Reading about LUFS, and how Spotify use it made me think - so I looked at the loudness meters in Cubase with the mastered material and I'm struggling with the results. I picked a few tracks at random and the results are detailed below. Type _____ Cubase Meter_ Integrated LUFS __ Momentary LUFS__ Range LU__True Peak dB Loud Track____ -5.7_______-18.3____________-15 _________3.3_______-5.3 Loud Track_____-5.1______ -17.1____________-13.7 ________ 2.7______-3.5 Modest Track____-7.5______ -23.9___________ -19.9________ 1.5______ -7.3 Gentle Track____-10.9______ -24____________ -19.7________11.3_____-10.3 I'm very happy with how they sound relative to each other - nothing unusual there, but the figures seem all over the place on the new LUFS meter I've never previously even used. When we master - and there are 61 pieces in the project, I look at the old peak meter after mixing and I may have to tweak up or down the levels a tiny bit on the master to make them sit with each other by ear - but the LUFS readings are wild - and I'd have to make major changes to make them fit a pattern. Is LUFS simply something that applies to how loud, pop/rock/dance music is perceived? It seems to offer no relevance to this kind of music that we do at all. Can anyone see any major issues with the LUFS measurements compared to our old system of just having peak 'bands' - where a loud piece would range somewhere near -5dB FS and the quiet ones would be happily at -10dB FS- ish? Have I totaly misunderstood it? Sorry about the formatting, tables don't work too well.
