+Description
+-----------
+
+This is a demo showcasing the sound-handling capabilities of Renode on the example of a Zephyr application running on LiteX with the I2S module.
+
+The application copies the stereo signal encoded in 24-bit PCM format (signed, little-endian) at the 44100Hz rate from the input to the output.
+
+By default, the demo runs the simulation for 3.2 virtual seconds in order to copy a 3s sample containing a 440Hz sine signal with periodical beeps.
+The user can change these settings by providing the following variables:
+* $zephyr_application - an ELF file with the application to run on the CPU,
+* $simulation_duration - a period (in virtual seconds) for the simulation to run,
+* $input_file - an input sound sample (in the format described above).
+
+How to run
+----------
+
+The demo requires an `output_file` that points to the file containing the sound data generated by the Zephyr application.
+
+Run the following lines in the Monitor in order to run the demo:
+
+    (monitor) $output_file=@/tmp/output.pcm
+    (monitor) include @scripts/complex/litex_i2s/litex_vexriscv_i2s.resc
+
+Note: There is no need to start the simulation after including the script - it will run the simulation for 3.2 virtual seconds automatically.
