Does Volumio play Flat?

The sound is very musical, and nice.
Just wanted to confirm that Volumio 1.38x plays without any treble / bass boost.

Hey @SanjeevM,

Thanks for raising this. Just to clarify first - when you say “Volumio 1.38x”, do you mean the very old v1 series (from about 2015–2016), or was that perhaps a typo for a more recent 3.x version? It would help us to know exactly which build you are on.

On the main point: Volumio is designed for bit-perfect playback. By default it does not apply treble, bass, EQ, or any other DSP shaping. What goes into ALSA is what comes out, unless you explicitly enable resampling, EQ, or plugins that alter the audio. So in that sense, yes - it plays flat.

Kind Regards,

My bad. I meant Volumio version 3.832.

Plugin Fusion DSP and Camila DSP.
You can adjust the equalizer however you like and match more or leave it uncorrected.
