Feature Request - Auto Volume w/ Speed

**hari-bhari** · 11-27-2006, 04:12 PM

I oftentimes find myself having to turn up the volume once im on the highway, so it would be nice if CF had an autovolume feature to adjust based on speed read from the GPS.

My gf's h3 has an auto-volume button with three settings: low, medium, and high, which basically adjust how agressively the volume gets adjusted (we keep it on low because its the least intrusive)

I figured this would not be too hard to do if CF had a built in COM port splitter, or if the user just had a program like xport.

Let me know what you guys think

i think that would be an excellent idea. it should also default back down to your actual selected volume if your speed can't be read (eg. when you lose your satellite connection through a tunnel).

IDK about others, but I patch my carpc through my head unit, so it stays at max all the time...

this is referring to the auto volume adjustment utilising the software eg. if you go over a certain speed as detected by the GPS the volume will automatically increase or decrease to accomodate for the increase in in-cabin noise. alternatively, when you come to a red light it will decrease so that you're not blaring up the music for everyone in the next district to hear.

i'm thinking a lot of people use Amplifiers and not HU's for their setup as well, and since Amps don't have the logic in them it would be good to have this driven through the software instead.

I have this built into my stereo, which I use for controlling the volume because I didn't want to get rid of my stereo, plus I have steering wheel controls. This is a great idea - could grab the info off of GPS (once speed is working consistently) or OBD.

Other front ends can do this, as far as I recall. Would be nice if CF did it too, yes...

would be nice

The same person who wrote the non-GUI plugin to set the volume to a specific level when he started the application and resumed from hibernation could convert his code to do this in a few minutes...

There is a getGPSInfo function to get the speed and he already has the code in place for the volume...

someone ask for the source and this could happen in no time...

The reason I built the SDK

Heh, I was just going to ask david if he would provide speed info from OBDII in SDK

. OK, first I'll try with GPS. Just one question david; should I make a continuous loop in which I check the speed and than adjust it (the loop would end on exit or hibernate or sleep (or it is not necessary?))?

Just use a timer to check speed...

I will look to add an OBD speed option as well, so your plugin could check both... check GPS, if it comes back as 0 after a second switch over and try to get it from OBD II
