DK-Technologies is offering a new booklet by Eddy Bøgh Brixen that explains many common questions about audio levels.
“Audio Levels and Readings” is supplied free with any audio meter purchased from DK-Technologies. It is also available as a PDF download from the company Web site.
According to DK, the booklet covers the basics such of levels and metering, including as what is an audio signal and how does one measure levels, along with more complex issues such as loudness, A-weighting and how analog levels relate to digital scales.
For a more in-depth treatment, DK-Technologies sells the book Audio Metering, also by Brixen.
