A list of algorithms and equations you can use and reference for your own DSP designs.
- Audio EQ Cookbook (aka RBJ Cookbook) - A collection of equations for calculating biquad filter coefficients.
- Cytomic Technical Papers - Excellent filter designs, equations, and explanations by Cytomic. Use these as a better alternative to biquad filters that both sound better and perform better when being modulated.
- Specifically the document SvfLinearTrapOptimised2 contains filters and equations that are a better alternative to the ones in the RBJ Cookbook.
- deip.pdf - A collection of high quality and fast sub-sample interpolators.
- Fast-DSP-Approximations - My own list of public-domain fast approximations of various expensive calculations.
- Musicdsp.org - A large collection of open source DSP algorithms by the community.
