Apr 22, 2013 · I asked myself how to compute dBFS (dB full scale) from a value of sample between 1 and -1? and in general?

Apr 13, 2023 · It is probably very well known that dBFS cannot be directly converted to dB SPL without knowing other information such as the technical specifications of the microphone. The questions are: …

Dec 14, 2014 · If your hardware driver takes the usual floating-point convention of the absolute extreme sample values being from −1 to +1, then you can say that your dB power values are dBFS — …

Jan 7, 2022 · The resolution in dB/LSB can be thought of as a multiplicator. With 1dB/LSB (Least Significant Bit), the dBFS-Value can be directly obtainend by reading the register. So, an 8Bit …

0 I'm trying to figure out how to calculate the dBFS for a complex input. I have an AD9361 part which has a 16-bit A/D and I believe outputs I and Q samples. Now I know you can calculate the dBFS for a …

Jan 9, 2023 · More details: Quantization noise is well approximated as a uniform white noise, from which we derive the equation for the total power due to quantization noise relative to the power of a full …

Aug 22, 2022 · As per my current understanding, the ADC datasheets for modern high speed ADCs give the noise level measurements in terms of Noise Spectral Density (NSD) in unit of dBFS/Hz. Now to …

Jan 24, 2024 · This will give you dBFS values. To convert to dBSPL, refer to the specs: An acoustic input signal of a 1 kHz sine wave at 94 dB SPL applied to the ICS-52000 results in an output signal …

Apr 28, 2015 · I'm trying to get the spectrum of my signal in dBFS units. I'm not sure what is the refernce that I should devide by. I computed the power spectrum as follows: 1) FFT normalized to the number …

Aug 1, 2022 · Unfortunately, the Python library I'm doing this processing in uses dbFS, and setting a gain of 6 barely makes a difference to the percieved loudness. Is there a method to switch between …
