Sansa Clip EQ db stepping (SPLIT FROM: Smarter equalizer frequency scrolling in Advanced etc)
« on: February 27, 2013, 06:42:43 PM »
 the 1/2 step should be removed. (that's what I think they are)
tap [>>]  5 time it only moves 2db. (maybe 2.5)

I don't use the eq.  Lady Gaga and other new artist will clip your eardrums before you can boot the thing.  Making your on presets is the way to go imo.

That A: - Is a silly way of handling this, and B: - Wouldn't happen.

Removing functionality definitely isn't the way to go here. As I mentioned in my previous post it looks like someone already thought of having two different values to increment the EQ settings by (EQ_*_STEP and EQ_*_FAST_STEP), but I haven't really looked at it any more than that. If it is what I think it is, it appears to be non-functional.

Using PMs to annoy devs about bugs/patches is not a good way to have the issue looked at.

It looks like the 1/2db step has already been removed.  The Clip Zip does not display .5db increments, however, the Clip Plus does display .5db.

The only thing i use the Grafox EQ is when creating EQ.cfg file and the Zip does not save in EQ freq in .5 increment.  iirc the Plus did.

I think what you are seeing is somebody removed the .5 increcment but you still have to press the button TWICE!! to incroment 1db.

btw it no big deal....for me.

Just to be unambiguous here, the problem is with frequency, not decibels. A constant db increment makes sense because dbs are a log scale and match hearing response, but a constant frequency increment as a disaster, because going the perceptual distance between 10khz and 20khz is the same same as between 100Hz and 200Hz, but at the moment it takes 100 times as long to scroll through.

I have a setup.cfg for headphones and earbuds using Bass and Treble inputs:

earbuds are bass+5db and treble +5db
headphones are bass-5db and treble +5db.
(had one for the car)

That makes my usable range on the EQ -3 to +10 for both devices. The meat of the EQ.
This also makes the EQ setting the same for all my devices on the same song and same volume.  So same eq.cfg file work on both output devices.

I split this topic, Crafty, because the original poster was talking about frequency stepping, and you're talking about decibel stepping.  If you have a feature idea regarding anything in the future please make a new topic, don't co-opt an existing one.

That said, I'm not sure this is a feature idea or a bug report.  I believe I can speak for the developers when I say that 1dB stepping size is a no-go.  That's too coarse.

What I suspect you're seeing is (and I don't have a Clip to check on, my Nano is my smallest screen) is that you don't have enough screen real estate to display an indication of the 1/2 decibel stepping in the graphical EQ screen.  Perhaps this is a bug, perhaps it is intentional behavior...

I agree, I thought there was a linear issue with db at high freq. 

Please delete this thread.  It would be the Clip Zip with the db stepping issue, fwiw.  Clip+ is ok.

II thought there was a linear issue with db at high freq. 

I don't follow...
