Dbfs to db spl converter

I used pink noise and an SPL meter, and calibrated the monitor output in accordance to -18 dbFS = 0 db. If I want to record at -20 dbFS = 0 db, I'm assuming that I just need to feed a 1k tone at -20 dbFS from my Mac to my board, then calibrate; that the difference of -2 dbFS (monitoring, not signal level) is, in the real world, negligible or ... DECIBELS A tenth of a Bel? The decibel (abbreviated dB) must be the most misunderstood measurement since the cubit. Although the term decibel always means the same thing, decibels may be calculated in several ways, and there are many confusing explanations of what they are. So if you have the need to convert M4V files to MP4 for free, Handbrake could definitely be the best consideration. 2. Freemake (Windows) Another best free video converter for M4V (non-DRM) is Freemake M4V Converter that could convert M4V free to MP4 and more other video and audio formats and devices with ease.
