AutoEq VS osmand_map_creation

I'm trying to follow this general process of EQing laptop speakers, which cites the AutoEQ Github wiki for digitizing a frequency response graph and converting it to CSV. The OP references converting the graphical data from an A-weighted scale to the dB scale, as well as interpolating more data points on their 20-frequency graph. Even without worrying about interpolation, I tried to follow the Github guide and just got hopelessly lost.

I have a topping dx3 pro+ and use https://github.com/jaakkopasanen/AutoEq/tree/master to play around with EQ's

jamesdsp/ An audio effect processor for PipeWire clients. It also uses presets from AutoEq.

what u can do do is go here https://github.com/jaakkopasanen/AutoEq/tree/master/results, pick and download the file for ur headphone and add it in APO equalizer as a second "graphic equalizer with variable bands" that will correct the first EQ with a curve made for ur headphone

Parametric EQ apps for Android can be googled, I use PowerAmp. The Qudelix takes care of all of that with its app to the point where you can load from a giant list of EQ sets they made from community data - Not all of it is accurate, better to go to the source. You can find EQ presets on the oratory1990 subreddit, Amir’s reviews for that particular headphone on Audiosciencereview and crinacle’s as well as rtings here: https://github.com/jaakkopasanen/AutoEq/blob/master/results/INDEX.md

I always recommended hearing before buying, but I'm assuming you can't try many in person so use AutoEQ to get an idea what you like - https://github.com/jaakkopasanen/AutoEq

https://rogueamoeba.com/soundsource/ (this has parametric EQ but it's a bit buried IIRC. It also has built-in support for AutoEQ according to this page so you might have to do almost nothing if you like the Harman curve)

For anyone interested, here is how you import custom maps (obf files) to iOS using the Files app without iTunes: Download an obf file, for instance, from here or use OSMAnd Map Creator to make one: https://github.com/pnoll1/osmand_map_creation / https://wiki.openstreetmap.org/wiki/OsmAndMapCreator

Might take a look at https://github.com/pnoll1/osmand_map_creation as it pipes millions of address points into the regular map creation process, or https://shallowsky.com/blog/mapping/osmand-making-overlay-maps.html as you could perhaps paint the line features into a raster then encode the raster.

Importing data from other sources into OSM is almost always a long and complicated process. It's usually not the most accessible thing for new mappers. Try to find out where a project stalled. Maybe contact the author of the wiki page you mentioned, or get in contact with your local community (most channels should be listed on https://community.osm.be ). From your data user perspective: there's a small project called OpenSuperMap where the maintainer creates files for Osmand that contain both all OSM data and all the addresses from some official source. So you get all the usability without having to finish the import first. Have a look at https://github.com/pnoll1/osmand_map_creation , maybe your region is already listed. If not, add an issue. The tool works with OpenAdresses.io so it should probably work.

For OsmAnd, /u/pnoll uses OpenAddresses to make OpenSuperMaps available as a replacement files for a limited set of geographic regions. In fact, those in covered regions can use them to work around a recent OsmAnd map data update problem.

Yes, I agree that data balkanization represents a significant hindrance for further development of openstreetmap. Fifteen or so years ago I was experimenting with importing DEM files from the US into Blender for landscaping, and finding the data was frustrating. Sometimes the data was available at a state website, other times at a federal website, sometimes also available on the website of that mapping program. Surveys within a given geopolitical constraint would be found on the website of whichever department provided the funding. I understanding that, even if ignoring legal realities, merging this data into a single "ground" (heh) truth would be a herculean task, scientifically. But there was no common database or delivery method. Some departments would link to FTP sites, other would provide arcgis downloads via an interactive web tool. I'd have to depend on user-maintained blog posts to even find the data. And the best data was always locked away behind secure portals that I couldn't get access to.

Nowadays openstreetmap is running into the same problem at the municipality level. In the US, if I understand correctly, geographic data is under copyright to whichever governing entity and not eligible for import into openstreetmap.

Take for example the excellent app Every Door (https://github.com/Zverik/every_door) with a focus on easily adding building information. In the US, openstreetmap has no address information. Either that or very little address information - but none in my area. So it'd be easy for me to add building nodes with house numbers but I won't be doing that. Not only is it a massive commitment, but the data is already available at openaddresses.io. The catch? It's "probably" license-compatible with openstreetmap. Before merging, all that data would have to be reviewed by a team of lawyers. That's not something a software developer can help with.

In existing threads here, a top complaint about OsmAnd is that lack of address information. Try planning a route without addresses, and without constantly switching to Google Maps to convert address to coordinates. Not very user friendly! Opensupermaps (https://github.com/pnoll1/osmand_map_creation) is a user-maintained merge of openstreetmaps and openaddresses.io, but it doesn't integrate with OsmAnd's data update system.

And that's how data balkanization is breaking openstreetmap, right now.

While not ideal, I've found a usable solution.

This GitHub repo [1] has map files generated using OpenAddresses.

Load the appropriate one for your area and you can search using addresses in the normal format. They currently provide maps for North America, and are regenerated roughly monthly.

(Thank you pnoll1!)

Try OSM. It is more reliable than google in performance now, believe it or not.

Address lookup is a shortcoming, and there's this https://github.com/pnoll1/osmand_map_creation to help you get around that, and sometimes the routing algorithm used by Osmand in particular can be goofy from time to time, I can't speak to other clients. Finally, there's traffic, which is not a problem that can be resolved without collecting and processing data from all users, which I find unethical and so will live without.

There are 2 ways that address lookup can be fixed. The first is this Dev https://github.com/pnoll1/osmand_map_creation/releases/tag/0.90 has a list of osm maps with address lookup built in. You download the ones you want and replace your map files with them and turn off auto update of maps. The second is an app in google play store called addresstogps 2 . You can enter the address then it gives the option to open the GPS coordinates for it in any app you choose. However it does use google as the search so its maybe not ideal for everyone.

If you use this website to supply your map source, you will be able to do the search that way.
