"Tagged" EQ PreSets - Possible?
MarcGuay:
Most audio editors have batch processing.
Febs:
I think that the "EQ is supposed to be for hardware" mantra is really overused here. There are good reasons that I can think of to have folder-based configuration settings, including EQ. For example, I generally use certain EQ settings for music, but not necessarily if I am listening to audio lectures.
Similarly, there are also many good reasons for not wanting to have to pre-process music files to apply EQ. For example, I have a substantial amount of music that I have downloaded in MP3 format from emusic.com. The quality of these recordings varies widely. There is no way that I am aware of to use an audio editing program to adjust the EQ on these recordings without suffering a quality loss as a result of decoding and re-encoding the MP3s. It would be very helpful to have a folder-based EQ setting for such files.
Folder-based configuration settings would have additional benefits other than just allowing users to specify EQ settings for a particular album. For example, I would generally like to have study mode on in my "Audiobooks" and "Recordings" directories, but off otherwise. Folder-based configuration settings would make this possible.
KindOfBlues71:
Well said Febs! This open-source project seems quite closed-minded at times...
Llorean:
It's closed minded to realize "adding every single idea can make the software worse, not just better, so everything needs to be carefully challenged and weighed"?
It seems closed minded to me to dismiss the project as closed minded just because you don't agree with certain choices it has made.
Every idea should be challenged. Period. Socrates once said "The unexamined life is not worth living." Simply accepting an idea, or simply dismissing it, would be closed minded. But to challenge it, seek its weaknesses and strengths, and once fully examined, to make a decision, is quite opposite. But to call it closed minded just because you think the decision is wrong is still foolishness.
As to what saratoga said, his no was in response to whether or not it's possible. The person simply asked "can this be done with Rockbox" rather than "can this be added to Rockbox", and he said "No, plus it doesn't seem to make sense."
In response to Febs: Why would you need different EQ settings for your audiobooks, etc? Wouldn't they still be played back on headphones with the same response curve? As to folder based EQ, wouldn't it make more sense to have perhaps tag-based EQ offsets or something? If it's truly individual songs that are poorly mastered, it seems like you'd want to correct that song back to being "neutral", then have your EQ corrections for the hardware still applied on top of that.

I can see that with audiobooks it may be less important to the listener to preserve a flat frequency response over the whole audible spectrum. I can easily see that a user might prefer to avoid expending the battery cost (however meager) associated with the software EQ in this case.
With regard to correcting a song back to "neutral" and then applying hardware corrections on top of that: Are you talking about some kind of delta configuration that allows you to adjust a parameter relative to its current value rather than setting an absolute value?
