Re: Metering Classic vs Sample Peak
It depends.
If you are not clipping at any point in your analog signal chain prior to your A/D converter, and your input signal happens to be in the yellow, then yes, you can record in the yellow. If you are clipping at any point in your analog signal chain prior to your A/D converter, and correcting that situation means you are no longer in the yellow, then no, you cannot record in the yellow.

Re: Metering Classic vs Sample Peak
Kenny has made a great tutorial on recording levels:
http://www.kennymania.com/recording-...-in-pro-tools/ It should answer many questions about setting the proper levels. That is where I got the -18 db.

Re: Metering Classic vs Sample Peak
Sorry but that tutorial just utterly sucks. It will add to already lost users inherent confusion, and especially badly he just conflates analog signal levels in dB-something with digital dBFS. And never explains either. If a user is not clear on the difference and what is/could be happening on the analog side vs digital clipping at the converter then they really have no chance.
And leave the damn meters in Pro Tools alone, if somebody made offsets like that (not related to precise analog calibration) to my setup they would have their fingers removed. |

Re: Metering Classic vs Sample Peak
Not all agree.
"The ability to recalibrate the meters reference level, and the colour bands may finally make Pro Tools meters worth taking notice of during recording - I think a lot of people just tend make sure the meter stays mostly in the green zone, and that they don't get too many peaks above about -9dBfs." -Carl Kolchak "Big Thanks for that Video as it was cool to see how other members think and use the input levels in PT. " -Southsidemusic "Thanks for that, Kenny. I found it very enlightening. Didn't know analog's optimum level is -18dB. I've seen guys drive levels too hot into Pro Tools quite often, which isn't even necessary with 24bit recording. The default meter setup encourages people to crank it." "Going to set my meters this way, it really should become the new standard." -WreckSpocka "Yes! Yellow is the new red. Converters have about 120dB dynamics and 24bit file has 144dB so in theory we are not losing anything if we record -24dBFS and I'm talking about PEAKS here." -JFreak "As I said, I record at these conservative levels as a matter of course (used to be hotter when 16bit was the only real option, but there was usually some hardware compression in the chain too), but you demonstrating that PT11 has the ability to recalibrate the metering is a really useful tip, and finally makes PT meters worth looking at on the way in, beyond just the peaks. Thanks for bringing that to my attention." -Carl Kolchak "Thanks for that great video Kenny! It was very clear and really helped me understand digital levels! Im a huge fan of all your videos and the reason i maintain a membership with groove3. Your a huge asset to the audio industry." -grant howarth "Bottom line, I reckon you are right about the levels issue and I recommend others give it a go. Once you get over the small waveforms thing, it'll be hard to go back. Your recordings will thank you. Big thanks to Kenny." -quantise To each his own.

Re: Metering Classic vs Sample Peak
Yes. Just turn up the damn monitoring volume (you have a knob for it, right?) instead of trying to kill the AD converters. Transients are lost very easily.

There are more than enough clues here that the OP has one or more issues on the analog side. Yet the fixation remains about what color some digital meter is showing, not more useful things like mic technique, checking phantom power, (signal generator) testing the preamp, trying a better preamp, ... Stuff that I suspect everybody here replying to this thread would have instinctively done... and we all would all likely be starting this recording with tons of ADC headroom. |

Re: Metering Classic vs Sample Peak
Thank you for that. Seriously. It made my day to hear there is at least one person that gets my message

Re: Metering Classic vs Sample Peak
Thanks for that Bob. If you got the time, please elaborate on these observations.

Re: Metering Classic vs Sample Peak
There is always a dark figure (at least one more). You nailed the holy truth together with Darryl in post #6 and #7.
