Thread Summary

                The user asked about when to use single-precision vs. double-precision filters in SigmaStudio. The final answer indicates that single-precision is generally sufficient for most filters, but double-precision is recommended for filters with cutoff frequencies below 10% of the sample rate or very high Q values, due to reduced quantization error. Double-precision calculations use about twice the instruction count, so the trade-off between performance and processing efficiency should be considered.

SigmaStudio allows me to use either single-precision or double precision for most filters in the library. When should I use single and when should I use double?
