The exported header file is missing the include for stdint.h for the used uint32_t type. Without it some builds fail to warning. Also the copyright text is updated. This patch also adds static const to the array declaration. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com> (cherry picked from commit d8560dc)
Need to drop the TLV header (used for Linux kernel bytes control) from data to keep the existing format after the header was added to sof-ctl generated data header. This header is not passed to firmware, only the kernel that this usage of filter coefficients passes, is using it. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com> (cherry picked from commit a3450ba)
This patch adds script sof_sound_dose_time_domain_filters.m that exports IIR and FIR coefficients to approximate A-weight function. The current choice is IIR only for lower MCPS load. The script sof_sound_dose_blobs.m creates a few control blobs to test the sound_dose component. A simple script sof_sound_dose_ref.m to compute dBFS and MEL for a wav file is added to compare with firmware reported values. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com> (cherry picked from commit f908a2f)
The added plot is useful especially with parametric IIR equalizer tuning to see achieved response error vs. target. A numerical mean(abs()) value of error is printed to help see filter parameters change impact. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com> (cherry picked from commit 3b753ec)
The build topologies are - sof-hda-benchmark-sound_dose32.tplg - sof-mtl-sdw-benchmark-sound_dose32-sdw0.tplg - sof-mtl-sdw-benchmark-sound_dose32-simplejack.tplg The controls are for example initialized to - sensitivity 100 dB, 0 dBFS equals 100 dBSPL (a worst case loudness) - volume 0 dB, assumes codec gain for headphones is set to max - gain 0 dB, user's music playback is not attenuated Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com> (cherry picked from commit c96891e)
This patch adds a new SOF component Sound Dose. The purpose is to calculate for audio playback MEL values (momentary sound exposure level) to provide to user space the data to compute the sound dose CSD as defined in EN 50332-3.
