tools: tune: Generate ctrl bytes from params for DRC Used the similar parameter set as the DRC kernel in CRAS to generate ctrl bytes for DRC component. Plotted input-output dB response curve with the specific parameter set. Signed-off-by: Pin-chih Lin <johnylin@google.com>

tools: tune: Add tools to generate ctrl bytes for DRC This commit adds the tools to generate the control bytes for the drc component. To generate the control bytes, run the example_drc.m script. To tweak the parameters modify the values in example_drc.m and run it. This is still WIP. A fixed set of coefficients is temporarily used in drc_generate_config.m Signed-off-by: Pin-chih Lin <johnylin@google.com>
