Local triggers

on_sound_loop

This trigger is called on every sound loop. In lambda's you can use local variables:

  • volume_smth (float): Either sampleAvg or sampleAgc depending on soundAgc; smoothed sample.

  • volume_raw (int16_t): Either sampleRaw or rawSampleAgc depending on soundAgc.

  • fft_major_peak (float): FFT: strongest (peak) frequency.

  • sample_peak (bool): Boolean flag for peak, responding routine may reset this flag. Auto-reset after 50ms.

On Sound Loop trigger

music_leds:
  id: music_light
  on_sound_loop:
    - logger.log:
        format: "${friendly_name} Sound loop, %f %d %f %d"
        args:
          - volume_smth
          - volume_raw
          - fft_major_peak
          - sample_peak
