The level your application reports as the RMS level is *your* answer to what we’ve found to be the sweetspot for podcast RMS levels. If you are looking for an answer relative to your audio-processor of choice, the best way is to run a real-world program through The Levelator then measure the resulting RMS level using your software. So the answer to Gregg’s question is that The Levelator adjusts speech to -18.0dB RMS, but that isn’t a value you can plug into any other program. (Is one recording half as loud as another because the speaker in the first one pauses twice as long between words?) In fact some of the most-expensive utilities don’t exclude silence at all, rendering them virtually useless for this aspect of spoken-word processing. Each application has a different way of excluding segments of silence from the RMS calculation.
#Apps like levelator pro
wav file and said, “this is standard,” and then you measured the RMS level of that track in various apps such as Pro Tools, Sound Forge, Soundtrack Pro, etc., each app would give you a different value. There isn’t a single value that works for even two different audio-editor applications let alone all of them. I’m not trying to be elusive or secretive.
Unfortunately, it’s a very complex answer. Two days ago Gregg McVicar asked: “So what was the RMS value that you found to be the sweet spot for podcasts?” Over on the discussion mailinglist from AIR (The Association of Independents in Radio), we’re revisiting the recurring discussion about RMS levels in spoken-word audio files.
