1. 'Average the responses'. Next switch to 'EQ', choose Manufacturer: Generic, Model: Generic.
   
2. Under Target Settings choose Target type and match LF Cutoff and LF Slope to your measurement. Choose a House curve you like. Some use flat response, some use B&K - see link above for the one I've chosen.
   
3. 'Calculate target level from response'. I recommend to rather go lower than the calculated target level, with almost no valleys below the target curve (and ignore the dialogue if xy% is above house curve...). Since peaks can be corrected for, valleys caused by interference not quite.
   
4. The other digression I allowed myself from Julians instructions was 'Overall Max Boost'. He says to choose 0dB.  I choose 3dB.
   
5. Under 'Filter Tasks' 'Match Range' to your speaker output.
   
6. At minute 13 he chooses 'Export filter settings as text'. We don't do that. Instead we go back to the main window and choose File>Export>'Export impulse response as WAV'
   
7. We see the 'Measurement impulse response export' dialogue: Check 'Mono' / Choose the Average measurement you've created for which you've created filters for / Choose Export measured IR / At the bottom check all the sample rates you want to play music with. For me it's 44.1kHz, 48kHz, 88.2kHz and 96kHz and hit OK / Choose location to save file
   
8. Your chosen file name will automatically have the sample rate attached, e.g. yourname-L-44k.wav. Replace 44k with 44100 so that the filename will be, e.g. yourname-L-44100.wav. Likewise replace 48k with 48000, 88k with 88200, 96k with 96000 etc. This is required for automatic sample rate switching to work!
   

1. Under Audio>Equalizers - Click on 'EDIT' CamillaDSP settings
   
2. Under Pipline editor: Status: On / Expert mode: On
   
3. Under File management> Configuration / Hit 'NEW' & Enter Name - e.g. MyConfig
   
4. go back to prior screen with upper left arrow
   
5. Under Audio>Audio Output>Volume type select CamillaDSP
   
6. Under Audio>Equalizers CamillaDSP: select 'MyConfig' --> SET
   
7. Click on 'EDIT' CamillaDSP settings
   
8. Under Settings>General>Signal processing: select 'MyConfig' and 'SAVE' (may already be selected)
   
9. Under File management>Convolution click on 'Upload'
   
10. Upload all wav files you've created in step 1.
    
11. 'Pipeline editor' hit 'OPEN'
    

1. enter name, e.g. ir_left / type: Conv / subtype: Wav
   
2. Now hit on icon above trash icon to select (one of) the filter(s) for the left speaker you have created (as described in paragraph A.), e.g. yourname-L-44100.wav
   
3. in the filename replace 44100 with $samplerate$, e.g. yourname-L-$samplerate$.wav
   
4. Repeat for the right speaker to create 'ir_right'
   

1. hit '+' sign / enter name, e.g. Loudness / type: Loudness / fader: Main
   
2. values for high_boost(6), low_boost(6) and reference_level(-5) depend on your setup - I've chosen values in brackets
   

1. type: Filter, channel:0
   
2. hit +-sign in new filter twice and create the 'ir_left' and 'Loudness' filter pipeline
   

1. type: Filter, channel:1
   
2. hit +-sign in new filter twice and create 'ir_right' and 'Loudness' filter pipeline
   

1. In Renderers>Squeezelite hit 'EDIT' Squeezelite settings
   
2. In 'Other options' enter: -r 96000-96000 -o camilladsp -W -R vLE -S [replace 96000 with your chosen samplerate]
   
3. In Audio>Equalizers choose 'Quick convolution filter'
   
4. Hit 'EDIT' CamillaDSP Settings
   
5. in File management>Convolution 'Upload' the ir-curves with your chosen samplerate
   
6. In Settings>General>Signal processing choose 'Quick convolution filter'
   
7. Directly below in 'Quick convolution filter' choose the IR-curves for left and right channel you've uploaded
   
8. At the top, next to Settings, hit 'SAVE'
   

1. Go to Audio>MPD Options>General>MPD settings: EDIT
   
2. chose whichever Settings you prefer, recommended: SoX Resampling Quality: Very High
   
3. - 8. same as above
   

• Spotted errors? Get in touch.
  
• The reason I have put the easier Quick Convolution setup last is my expectation for the majority of hifi enthusiasts to prefer having their DAC do the re-/upsampling and not some open-source SoX algorithm. Actually I don't. I believe SOX upsampling is top notch - at least when using the -R v switch.
  
• Commercial products for home-use I know and heard of visualize a calculated expected outcome after filtering - like REW. But they don't offer actual measurement capability. Possibly to avoid cognitive dissonance and prevent buyers remorse. If someone knows how to easily measure room correction effectiveness with REW: I'm interested!
  
• The improvement delta of this exercise for my full range system was way higher than replacing my historic Cambridge Audio Dac Magic with an RME Adi-2 Dac FS. Nothing against the RME device - quite the opposite. I'm loving it for headphone listening. But the DAC apparently wasn't the weakest part from bit to ear. Room acoustics was. Now that I've completed this project I'm perfectly fine with the sound. No more Hifi tweaking. ....Probably :-)

Only I don't share you opinion on about the quality of sox resampling. If you search bit you will find a lot of reviews about, including measurement.

But there is an even better alternative by using the resampler of camilladsp itself.

Can you give instructions please to implement that?
