Radio EQ

(1/3) > >>

redblade8:
My friend has an EQ built into his truck radio that allows him to change the EQ setting's ( plus bass and treble ) while listening to the radio.

What would you think about this if Rockbox had this implemented?

Also, an option to add echo to songs 3% Echo, 18%echo...etc..to 100%?  ;) So what do you think? ^^

saratoga:
Not sure if thats even possible on a lot of devices.  Radio is usually routed to the DAC from the tuner without passing through the CPU so theres no chance to apply digital effects. 

redblade8:
Oh. I guess you'd Be right about that.

If it comes straight from the tuner , then what's being played is what's being played.

What about what is being outputted to the headphones? This can be manipulated by EQ? Or maybe something that the Sound from the Radio can go through before being played... I'm Not really sure.


Having Echo for just playing songs should Be possible though.

If theres a target out there that can route it through the CPU, then sure, you could do whatever you wanted with enough work. 

nls:
On targets that can do ful duplex it could be possible, you'd record samples from the radio, porocess them and then play them back. Not all targets' hardware can do it though IIUC. If your target has effects built into the DAC (like bass/treble) they may be applied to the analog audio from the radio already though.
