After you started the playback just check the sample_rate provided by audioInfo() or you could use the HeaderParserMP3 |

I understand that I have to check sample_rate from AudioPlayer -> AudioInfo()? |

The information is propagated along the whole chain: just read the documentation! |

Ok, I Understand. I'm doing something wrong because a 48KHz mp3 is playing accelerated but player.audioInfo().sample_rate return me 44100. |

Just set the log level to Info and check what's happening... |

Hi again @pschatzmann. I continue having problems with sampling rate propagation. I'm using player, metadatafilter, Helix MP3 decoder, Eq filter and AudioBoardStream as audio out driver. All is defaullt configured. The pipeline I think is, source -> decoder -> metadatafilter -> (equalizer) kitStream, then I not need to force notifycation. Then, where would be the problem? Thanks |
