I have a design where I need to compute a gain from the estimation of the input signal level in a specific frequency band. There is a wide dynamic range for this input signal, so I can not simply use a lookup table because input points are linearly spaced which is not accurate enough.
The RMS lookup table does not really help here because it includes time constants that I must avoid.
Having a simple lookup table with logarithmically spaced values would solve my problem.
Is there anything in sigma studio which could help me implement this without using a lot of CPU?
Are there any plans to include a log-spaced lookup table?
