Equalizer

Not only at too low volume, but also with nearly no bass and on the other hand with too harsh treble. This is the same with other recordings, too, like some Prince albums, etc. I wonder why better Hifi amplifiers are missing bass and treble controls and wish, that my naim uniti had some. (Is there a comparable system on the market that offers such controls? Maybe including Loudness controls?)

I came across the idea that I could bass boost the tracks with audacity. This works and it makes much more fun to listen to these old recordings, but it is really much work to find the right settings by experimenting with audacity on a PC, copying the files to the NAS, going to the living room and test the result, only to find that the boost was too much...

So... Well I nearly do not dare to suggest it, as I already can guess the answer (the same as for reply gain support ), but: Wouldn't it be an idea to include an equalizer into minimserver? It could be controlled via the web setting page. And maybe somebody could implement an smartphone app to controll it comfortably.

You should be able to use the ffmpeg equalizer filter to do this. See this page for some pointers. To specify the necessary filter options for MinimStreamer transcoding, you can use the stream.options property.
