For the OP, room resonances etc, as a temporary solution I had a test album with sine wave tracks, each one was named with the respective frequency xx Hz. You can generate one easy, there are generators online. Sure it would be good to have in moode, but would it be good enough or going straight to external solution would have a much better result? (REW for example)
I used REW with moode in past,not enough time to have fun these days...
Being that my raspberry DAC has no input, and also that any decent raspberry DAC has a flat-enough™ response, the more interesting way to do it was by using airplay.
There are tools like streamwhatyouhear, tuneblade (windows) or a modded pulseaudio ( http://hfujita.github.io/pulseaudio-raop2/ ) for linux that allow you to stream to moode while being seen as a speaker/output by your operating system.
This way you can simply select it as a sound card in REW and do it all in one step, air streaming the sweep without cables.
You just have to enable the acoustic timing reference when you play the sweep and it will self align.
Then you can generate the filters for the parametric EQ in REW. It's a bit limited having only 4 filters in moode, but trust me it can do a lot of difference in room.
After you generate them, you load and apply them in moode and do another sweep to see the result.
Now at this point you will hear the new EQ curve on music, but not on airplay
e.g. you want do do another recording to see the chart after the mods.
When I did this, the EQ curves weren't applied to the airplay sink at the time, moode's airplay streams always played non-EQ'd.
A one-line code edit was required in playerlib.php to apply the EQ also to the airplay stream.
