Function nih_plug::util::db_to_gain_fast

pub fn db_to_gain_fast(dbs: f32) -> f32

An approximation of db_to_gain() using exp(). Does not treat values below MINUS_INFINITY_DB as 0.0 gain to avoid branching. As a result this function will thus also never return 0.0 for normal input values. Will run faster on most architectures, but the result may be slightly different.
