RE: Equalizer
width_type=o means octave. You should specify the width in a few octaves. The whole bandwith is probably about 10 octaves. So 500 is way to much .
I advise to start experimenting at convOut=-af equalizer=f=20000:width_type=o:width=2:g=-5 for one octave down and one octave up from 20000hz. One octave down from 20000hz is about 10000hz. One octave up is about 40000hz. So you will reduce frequenties from 10000 to 40000 with width_type=o:width=2. |

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. This support is now available in MinimStreamer 0.5.14. To force the use of a converter for FLAC to WAV transcoding, you need to add a semicolon after the output type (for example, flac:wav24;). This will keep the output sample rate the same as the input sample rate and use the converter that you have specified in the stream.converter property. |

It's working as well as I hoped. I can now skip the DEQ22496 digital equalizer. Thank you! I'm thinking about making a spreadsheet to visualise the EQ settings. Anyone any thoughts? Greetings, Jaap |

Found this link to a spreadsheet based EQ visualisation: http://www.musicdsp.org/files/rbj_eq.xls In this spreadsheet you can define and visualise 5 EQ settings and see how they interact with eachother. For EQ settings you need to define frequency, Q and gain. |

I have modified the spreadsheet a little with a macro to create a "convOut" text line that matches the EQ settings. As visualised below I have raised the gain at 2000Hz and 8000Hz a little. In AutoHotKey I made a script to choose between four EQ settings <ctrl-1> to <ctrl-4> and sent the new setting to MinimStreamer. |

RE: Equalizer
This is very interesting. For which application is this spreadsheet implemented? If openoffice/libreoffice I could test it on linux or MacOs. If MS-Office, well, I had bad luck. Do you offer it for download?

You can use this to make your own macro. Alternatively you can manually copy Q11 and "paste special/text" to A21. |

RE: Equalizer
Hello Simon,
Music on my NAS is transcoded (and equalised) by minimstreamer using ffmpeg. I would like to apply the transcoding to my Tidal/Qobuz stream also. Is that possible somehow? |

RE: Equalizer
I think the best way is to use an RaspberryPI as streaming client (e.g. with Volumio as OS) and try to enable Acourate-convolving via brutefs or jconvolver. This would offer real room- and loudspeaker correction. I am planning to try this some day. It does not have anything to do with minimserver, but I was suprised if minimserver could do apply the ffmpeg equalising to a tidal/qobuz stream.
