RE: Equalizer
Great! Good to know that you need to acitvate transcoding to make the converter/equalizer work. Now I know I understand. But I have been wondering why converting did seem to do anything any more.
Back to my old question. Is there a way to combine two equalizer settings? f.e. convOut=-af equalizer=f=58:width_type=h:width=10:g=-4, convOut=-af equalizer=f=3520:width_type=o:width=4:g=3 Greetings, Jaap |

This depends on what options you specify. Transcoding from flac to wav with the same sample rate shouldn't cause any problems. I haven't tried the ffmpeg equalizer, so I don't know what effect that has. Quote:Thought I should tell you that I recently invested in a couple of You're very welcome! |

I think the best solution will be to change the convOut option syntax from: convOut=some option string, perhaps including a comma to: convOut={some option string, perhaps including a comma} |

RE: Equalizer
I have been experimenting with the FFmpeg equilizer. This spring I bought some bigger monitor speakers with bigger sound (Penaudio Cenya). However I missed the nice vocals of my old speakers (Penaudio Rebel). My amp is an English Sonneteer Alabaster without sound adjustment possibilities. So I added a Behringer DEQ2496 digital EQ between streamer and dac to reduce bass at 58Hz and highten the higher frequenties.
With FFmpeg setting convOut=-af equalizer=f=3520:width_type=o:width=3:g=3 in Minimstreamer I was able to recapture the sparkling sound of the Rebel speakers. I found this post and the linked pages on ffmpeq equaliser settings and frequenties in general very helpfull:FFmpeg Equalizer |

RE: Equalizer
I am trying to apply some equalizer settings for the first time now and cannot get it to work. To make it easier I have one question: Do you have to restart minim server after applying a property change?
If I want to reduce the highest highs, which frequency and filter I should choose? I am trying this setting: convOut=-af equalizer=f=20000:width_type=o:width=500:g=-20 (minim server running on a Synology NAS DS213+) |

To make it easier I have one question: Do you have to restart minim server after applying a property change? I can answer the first of these questions. Some properties require a MinimServer restart after a change and some don't. If your question is about the stream.options property, changing this doesn't require a MinimServer restart. |

RE: Equalizer
Ok, thank you. Yes, I am asking for the stream.options property. This makes testing different settings much faster.
Unfortunately I cannot produce any effect with the equalizer. I am transcoding flac to wav24 and tried to achieve an effect in treble or bass with different gains (positive and negative). I will continue trying around... |

Transcoding flac to wav24 doesn't pass the stream through a converter. This is why you aren't seeing any effect. The next update will support a new setting to force the use of a converter for FLAC to WAV transcoding. For now, you can specify an explicit sample rate for the output stream (for example, flac:wav24;96 or flac:wav24;44) as a workaround to force the use of a converter. |

RE: Equalizer
LOL. I am glad that you write this. I do not know how long I would have tried several settings tonight
With mp3 it works, but it is quite difficult to find the right settings... I will try the wav24;xx settings as well. Thanks Gert |
