    ○ M3u playlists with mp3 sound files, stored on the USB memory stick. PYKO-out can decode these sources according to 3 priority levels (priority1 being the highest priority, and priority 3 being the lowest). At any time, PYKO-out decode the highest priority which source is present. This allows the following : - getting automatic backup in case a source is lost (typically an IP stream).
  • Page 17 8 kHz to 48 kHz, G711 A-law or µlaw). In case the configured format does not match the received audio format, PYKO-out interprets this as an error and does not decode the stream. As a consequence, PYKO-out switches to the immediately lower priority (Stream priority level “n+1”).
