Transcribing the Electri-Q settings:

Low shelf filter, cutoff at 276Hz, -8.2dB, BW=2

Peak filters:

1. center at 650Hz, +1.5dB, BW=2

2. center at 1398Hz, +0.6dB, BW=1

3. center at 2532Hz, -2.7dB, BW=1

4. center at 2950Hz, -5.6dB, BW=0.5

5. center at 5300Hz, -10.1dB, BW=0.4

6. center at 8000Hz, -13dB, BW=0.3

7. center at 10090Hz, -3.3dB, BW=0.4

8. center at 11700Hz, -3.3dB, BW=0.2

(nonstandard filter) Butterworth highshelf, cutoff at 11700Hz, -5.2dB, BW=1

To convert into a format usable by rockbox, round frequencies to nearest 10Hz and convert bandwidth into Q factor using this online calculator:

Rockbox settings:

Low shelf, cutoff at 280Hz, -8.2dB, Q=0.67

Peak filters:

650Hz +1.5dB Q=0.67

1400Hz +0.6dB Q=1.41

2530Hz -2.7dB Q=1.41

2950Hz -5.6dB Q=2.87

5300Hz -10.1dB Q=3.6

8000Hz -13dB Q=4.8

10090Hz -3.3dB Q=3.6

11700Hz -3.3dB Q=7.2

High shelf, cutoff=11700Hz, Q=1.41

I haven't tried this myself on rockbox so tell me if this sounds correct or are my calculations full of it
