As we can see, the analog waveform is the same, only shifted in time. However, now the sample peak is a few decibels lower than the true peak. We set , so the true peak is or dB. The sample peak is the sample immediately before the true peak, which using our formula above is or around dB, a difference of over two decibels from the true peak!

We are also provided with a horizontal pink line, shown below, which denotes -12 dB audio level. This 'audio overlay' reference line can be found in both the Viewer window, audio tab and in the Timeline. Red arrow shows -12 dB reference line Audio waveforms peak at -12 dB Narrow dynamic range Red arrow shows -12 dB reference line

Just the dB value of the loudest peak in the file because one requirement is to detect wav files, which have errors in it. for example the loudest peak is at +2dB. var streamBuffer = File.ReadAllBytes (@"C:\peakTest.wav"); double peak = 0; for (var i = 44; i < streamBuffer.Length; i = i + 2) { var sample = BitConverter.ToInt16 (streamBuffer, i); if (sample > peak) peak = …
signal processing - How can I calculate audio dB level ...
https://stackoverflow.com/questions/2445756/how-can-i-calculate-audio-db-level
There is no calibration or reference measurements, just a simple calculation: dB = 20 * log10 (amplitude) The amplitude in this case is expressed as a number between 0 and 1, where 1 represents the maximum amplitude in the sound file. For example, if you have a 16 bit sound file, the amplitude can go as high as 32767.

Within the graph, the left side is for sound level and the right side shows the noise level in the dB unit. The X-axis shows the active time frame for the last 30 seconds. The graph is colored from blue to red zones where blue corresponds to the lowest sound level and red is for the highest sound and noise level.
