Wondering if there is a Moode demo I can try. TBH I dont want to spend the money before having a test run.

I am currently using Volumio and I had tested runeaudio and I dont like it after 1 hour so I short demo is sufficient for my purpose.

Hi @bigbear2003,

Iím not a fan of trial ware because developing and supporting a trial ware system is not a trivial undertaking and would compete for time to develop and support moOde itself. If you end up purchasing moOde and it does not meet your needs then just send me an email and Iíll refund your purchase.

-Tim

Default different values for L and R ?

I am playing with different alsa equalizer settings.
Setting 44,66,78,72,66,66,66,54,44,78 and exiting. Than when i am starting equal again, the settings for left and right channel for 31Hz and 8KHz are different (44,43) !

I can set again the same value (44) for both channel, exiting, starting equal and it is again different for L and R channel.

When i set the value 43 for both channel, than exit and start again, than both channel have 42. Hmmm.

another question - equalizer setting are from 0 to 100, 0dB is 66 ? Or 66 is reduced volume to have headroom for frequency correction ?
3dB coresponds to 12 or 22 ?

Any hint ?

Hi @sinski,

I see same oddness in the Alsaequal UI with my Piano 2.1 DAC but not with other DAC boards. Maybe its specific to how the Piano 2.1 manages its special Dual-Modes.

The EQ UI does not display dB and Ive never been able to find info about the mapping between the 0-100 Alsaequal scale and dB. The EQ plugin defaults to 66 which I assume is "Flat".

I sent an email to the dev for alsaequal re the dB mapping. If he responds I'll post back :-)

Default Vinyl touch

So, after studying the pictures of frequency response for different cartridges and reading articles about "howto make digital sound like vinyl" and making some tests on my hifi system - i played lp and then played the same recording from HDTracks with moode player i ended with those settings:

44,68,72,68,66,66,66,53,44,72

proposed name for the equalizer setting: "vinyl touch" ?

I try to explain why i have changed the values in this way. Most vinyl reproduction system are linear only between 500 and 2000Hz.

31Hz - bass in this area on vinyl is very rare, so value=44

66Hz - sometimes is little more, than at 1KHz, so value=68

125Hz - many catridges are adding some bass in this area, value=72

250Hz - between 125 and 500Hz, value=68

500, 1000, 2000 - linear, all values=66

Many even very expensive cartridges have lower output in the area between 2000Hz and 10000Hz, mostly with -3dB at 8000Hz

4000Hz value=53

8000Hz value=44

than many expensive cartridges have +3db or even more around 15KHz, so

16000 value=72

With those settings the sound (at least for me) is more soft and less fatiguing. Probably the area between 2 an 10 Khz is most important.

Maybe one day we will able to add some k2 distortion, little noise and changing some other parameters (everything below 200Hz is mostly monophonic) and we will be closer to wonderfull vinyl sound
We should not start endless discussion about those settings, with ssh and than "sudo alsamixer -D equal" everybody can find their favourite


PS if you want to save value 44, than you have to set 45, exit/start equal again and it will be saved as 44 ...

Hi Tim,

THX

maybe it is possible to add this as "vinyl touch"

54,67,68,67,66,66,66,60,54,72

it is more balanced, not so strong correction as the first one.

and the first one as "vinyl touch +"

44,68,72,68,66,66,66,53,44,72

after listening more i noticed that the first proposition is good for really bad early digital recordings with digititus, and other better with new warmer good digital recordings.
