ujfalusi · ujfalusi · commit f3f018ba5476 · 2026-02-11T13:47:02.000+02:00
The needed libraries should be placed in
sof/../cadence_libs/ directory if the overlay is used.

+Cadence Codec Configuration Overlays
+=====================================
+
+This directory contains Kconfig overlay files for enabling Cadence codec support
+in SOF firmware builds.
+
+Prerequisites
+-------------
+The Cadence codec libraries must be placed in the cadence_libs directory, one level
+up from the SOF project directory:
+  sof/../cadence_libs/
+
+Available Overlay Files
+-----------------------
+cadence.conf      - Base Cadence codec module only (no individual codecs)
+mp3.conf          - MP3 decoder and encoder
+aac.conf          - AAC decoder
+vorbis.conf       - Vorbis decoder
+all_codecs.conf   - All supported codecs (MP3, AAC, Vorbis)
+
+Usage Examples
+--------------
+Use with scripts/xtensa-build-zephyr.py via -o parameter:
+
+# Base module only (e.g., for Tiger Lake)
+scripts/xtensa-build-zephyr.py tgl -o app/compr/cadence.conf
+
+# Single codec
+scripts/xtensa-build-zephyr.py mtl -o app/compr/mp3.conf
+
+# Multiple codecs (use separate -o for each)
+scripts/xtensa-build-zephyr.py mtl -o app/compr/mp3.conf -o app/compr/aac.conf
+
+# All codecs
+scripts/xtensa-build-zephyr.py mtl -o app/compr/all_codecs.conf
+
+For more information about Cadence codecs, see the SOF documentation.
