This patch adds gain +30 dB and +40 dB variants of the high-pass filter blobs. These can be useful with laptop devices with microphones with low-sensitivity where e.g. +20 dB boost is not felt sufficient. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
This patch adds for use with sof-ctl blobs those set up the IIR equalizer component to apply 40 Hz high-pass filtering with gains of +20/+30/+40 dB. The blobs are useful for testing how much the pre-processing for microphone should apply gain for suitable recording level. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>

Note: The IIR blobs with more gain were used in thesofproject/linux#5325 to experiment with sof-ctl how much capture gain should be applied in a device where too silent capture was reported. |
