By default, only the changed areas are refreshed. It means if only a few pixels are changed in 1 ms the benchmark will show 1000 FPS. To measure the performance with full screen refresh uncomment `lv_obj_invalidate(lv_scr_act())` in `monitor_cb()` in `lv_demo_benchmark.c`.

- `assets/spectrum.py` creates an array of spectrum values from a music. 4 band are created with 33 samples/sec: bass, bass-mid, mid, mid-treble.
|
||||
- The spectrum meter UI does the followings:
|
||||
- Zoom the album cover proportionality to the current bass value
|
||||
- Display the 4 bands on the left side of a circle by default at 0°, 45°, 90°, 135°
|

- Display the 4 bands on the left side of a circle by default at 0°, 45°, 90°, 135°
|
||||
- Add extra bars next to the "main bars" with a cosine shape. Add more bars for the lower bands.
|
||||
- If the there is a large enough bass add a random offset to the position of the bars. E.g. start from 63° istead of 0°. (bars greater than 180° start again from 0°)
|
||||
- If there no bass add 1 to the offset of the bars (it creates a "walking" effect)
|
||||
- Mirror the bars to the right side of the circle
|

|

|

## Using spectrum.py

- install `librosa` with `pip3 install librosa`
