Recording a fairly loud singer through a condenser into a USB interface. The red clip LED on the front flashes on loud phrases, but the track in my DAW peaks around -12dBFS and sounds clean when I solo it. Am I actually clipping something I can't see, and which meter should I be trusting here?
Don't chase hot levels at 24 bit. -18 average and -12 peak is plenty of headroom and your noise floor is nowhere near a problem. The habit of tracking near 0 came from 16 bit tape-era thinking and it doesn't apply.
Worth checking which LED it is. Some interfaces put the signal/clip indicator on a bicolour ring around the gain knob where amber is 'good level' and red is clip, and people misread amber flicker as clipping. Look at the manual for the actual thresholds.
Then pad it. Also listen to the loudest phrase on headphones with the fader up loud — analogue clipping on a vocal is usually audible as a hard edge on the peaks once you know what to listen for.
It's a discrete red LED that only comes on for the loud bits, so I think it's a genuine clip indicator.
Also possible: phantom power pop or a handling thump hitting the preamp on a transient you can't hear because it's below 30Hz. A high-pass at 80Hz on the way in won't help the preamp, but a shock mount and a solid mic stand might.

Trust the interface LED — it's showing you the analogue stage before conversion, and if that's clipping the damage is already baked in before your DAW sees anything. The DAW reading -12 just means the digital signal is quiet, not that the front end is happy.
Most likely cause with a loud singer on a condenser is the mic's own output overloading the preamp input even at low gain. Two fixes: engage the pad on the mic or the interface if there is one (usually -10 or -20dB), and back the singer off to 20-25cm with a pop filter. If you have neither pad, moving off-axis by 15 degrees will knock several dB off and also tames sibilance.

Everyone has one of these. Engage it, then bring the gain knob back up until you're peaking around -12 to -6 in the DAW with the LED never lighting.

There is a pad on the interface that I've never touched in two years. Feeling silly but this makes sense.
