El problema parece estar en este trozo de código en podcast_audio_process:

ffmpeg \
  -hide_banner \
  -i $1 \
  -filter_complex "[0:a]${pan}[a]; \
                   [a]highpass=frequency=80[a]; \
                   [a]agate=mode=downward:range=-15dB:threshold=${noisegate_threshold}dB: \
                      ratio=3:attack=1.5:release=120:knee=10dB[a]; \
                   [a]ladspa=file=${compressor_so}:p=${compressor_name}:c=c0=0|c1=1.5ms|c2=4ms| \
                      c3=${compressor_upper_threshold}db|c4=6|c5=3db[a];
                   [a]ladspa=file=${compressor_so}:p=${compressor_name}:c=c0=0|c1=2ms|c2=12ms| \
                      c3=${compressor_lower_threshold}db|c4=2|c5=8db[a]
                      " \
  -map "[a]" \
  -c:a flac -ar ${AUDIO_RATE} -sample_fmt ${AUDIO_FMT} -compression_level 1 \
  ${td}/audio_gated_compressed.flac

Según la documentación del filtro agate la opción modeestá contemplada. Supongo que el problema es debido a la versión incluida en Debian.

Dado que el valor por defecto para mode sería downwardpodemos eliminar esa parte de la configuración, lo cual parece surtir efecto porque ahora pasamos a un error diferente:
