BTW. Thats my playout setup. I have to record a mp3 for the playoutsystem of the local radiostation.

Expect around -10 dBm for a tone at ‘0’ level in Rivendell for those. OTOH, ASI cards with analog outputs will give you +4 dBm at that level (unless you've tweaked the gain trim in rdadmin(1).

Re: [RDD] RDAirplay vu meter
The choice of -13 dB is deliberate; it's 13 dB below absolute maximum (all ones). What sound card are you using? Turm up the gain, or use a line amp if you have to. Rivendell machines running tone at zero on the rdairplay meters tend to be quite a bit lower than +4 dBm.

Re: [RDD] RDAirplay vu meter
Hello Cowboy, thanks for your explanation. I don't want clip or be loud i'm asking only because i see a discrepancy from my previous automation and rivendell. My previous when vu meter was to 0 also in audio processor was like that and that's all. I prefer to don't add amplifier in the chain to not introduce any noise. Anyway great explanation thanks again Regards Gabriele ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev

( clip is a catastrophic system failure ) Rivendell 0 is showing you the normal, sane operating standard adopted many years ago. It's actually 10 db higher than the historic standard built into analog consoles of my day. There's quite a bit in the archives about reference level. What's not there, just as FYI... In my day, reference level was based on a 400 hertz sign wave recorded on tape at a magnetic flux of 100 nano-webers. The AC voltage at the head depended on the head physics, and on the bias level recorded on the tape. Higher bias produces much better fidelity, but subtracts directly from dynamic range. The following amplifiers were calibrated to produce 0 reference level when that standard tape was played. Most normal audio had an apparent discrepancy with standard level of about four to one, so in order for an an operator striving to constantly maintain an average at 0, the amplifiers would need about 20 db or so of headroom to avoid clip. In analog, clip is annoying, but not catastrophic. Still, we're professionals, so please try to act like one ! Thus, standard level was generally about 20-26 db below the rails. The rail being the power supply voltage, and thus the absolute maximum instantaneous peak that could ever hope to be achieved, assuming the supply didn't sag. Attempting to run above standard to get "loud" is simply unprofessional, as well as risky dangerous to fidelity, ( opinion ) and stupid ! If you want loud, add an amplifier. That's what they do. -- Cowboy Grief is the Reminder that we Loved.

[RDD] RDAirplay vu meter
Hello i ahve a stupid question on vu meter in rdairplay. i normalized tracks at -13 dB and vu meter show me track volume so to 0 but in audio processor is -13dB. If i normalize tracks at -3dB i see vu metere in rdairplay goes over 0 almost near red zone but in audio processor i see the volume is -3 dB. Is the 0 on vu meter real 0 or is around -13dB?
