I need your help guys For the first time, i have to mix a commercial for French TV following EBU R68, (signal dynamic shall not go over 21db. Usually I would just master it following the EBU R or ITU-R From what I read, R68 is based on the old PPM peak metering which really. My conclusion, if you use the DIN PPM scale (RTW) and the EBU-r68 dBfs scale, you have a headroom left of only 6 dB in the digital betacam.

Footroom is the needed level between noise and the lowest audible signal music, speech. Measuring audio levels with RMS meters or any other standardized average level meter that indicated loudness or average level over a certain time constant do not show peaks that could be already over digital fullscale!

I would bet a mix at -9dBFS max truepeak with a dBFS alignment 1k tone at the beginning of the mix the tech specs should say where to beu the 1k tone would be suffice.

As radio stations competed for attention and to raise the listener scores their ad revenue is based on, they used audio compression to give their sound more impact.

Alignment level

TV sounds like ass because there are broadcast loudness standards that sound engineers push to their limits. I’m guilty of this as well, because everyone does this so if I don’t ebh mix will sound weird compared to everyone else’s and my client wouldn’t like that.


Good luck with your search for an answer. R68 was introduced in Dual mono identical stereo channels is only accepted after prior agreement with the Broadcaster’s sales department.

The lowest possible sample is for instance for bit audio: Digital audio players such as the iPoddemonstrate the need for a common alignment level. The analog input is measured as root-mean-square RMS. This article does not cite any sources.

From what I read, R68 is based on the old PPM peak fbu which really shouldn’t be used much anymore. The top shall be formatted as follows: I work at a voice over company where I master shit all day long. This is largely due to the use of slow responding VU meters in almost all analog professional audio equipment which, by their design, and by specification responded to an average level, not peak levels.

The broadcast loudness standards are pretty cool though, because they prevent programs, commercials, movies etc. The only downside is that most shows will sound relatively the same – very little in dynamics and the dialogue is always around the same volume whether it’s whispered or yelled. For bit digital audio the dynamic range is dB and for bit digital audio it is dB.

Please log in to reply. Ah, yes, the slow release is a give away to a limiter being set totally wrong. The European Broadcasting Union EBU specifies several nominal levels and resulting headroom for different applications.

Watching VU meters for both the left channel and the right channel in real-time was the most hellish archaic BS ever.


I’m working procrastinating on a 30min doc right now on a small African island’s struggle with climate change which is OK. The footroom is needed to keep noise inaudible, headroom is needed to avoid clipping of e68 in the music signal.

Studio recordings normally use a headroom of 20dB to securely avoid distortion. Whether it sounds like ass on some channels depends on what they are doing on their end.

I at least get to break out some ambiences I don’t usually get to use which is a plus.
