I am looking for a simple treble and bass EQ for adjusting. Is there any plugin available? Is the CPU too weak for handling an eq?

Running local lms? If so on what OS/computer. More specifics would be helpful.

Sorry, let me clarify myself:

All I would like is little less treble, on some channels voices tend to sound a bit harsh.

Thanks for your prompt reply! Originally Posted by garym

Yep. Boom had treble and bass controls, which were nice.

Agreed - a little extra bass and quite a bit of extra treble makes the Boom sound perfect IMO (that's how I've always set up every audio device - personal preference). The Radio doesn't match it I'm afraid. Does anyone know if the Boom's tone controls are implemented through hardware or software? Originally Posted by garym

AFAIU, the Boom EQ-ing (and other sound processing) is done with a DSP which is controlled via the firmware. I'm not aware of the Radio having a DSP like that.

Yes I think there is some kind of dsp hardware chip in Boom it also does the xover , radio is simpler would be able run that in fw . Originally Posted by Soulkeeper

The clever Logitech DSP all seems to happen through alsa plugin(s), I think. I could be wrong. Ideally we would be given another, dirt cheap, EQ plugin to add into the chain. Could it be that simple ? Originally Posted by Mnyb

Just a matter of figuring good DSP filter values to load up, and into which chip registers to load them. Looks like it could be done from the command line (amixer) as the registers appeared to have been exposed to view (De-Emphasis Filters [1]). It's a while since I looked, but I don't think memory is playing tricks on me. Existing software seemed to be leaving them untouched. Of course, it could ruin all the good work done by Logitech's DSP !
My goal would be to add a simple bass unboost button to quell boomy baritone announcers. But it's not going to happen for a while unless someone else does it. There'd be some intricacies around switching to and from headphones, etc., because the chip's input & output is mapped differently from normal speakers.
So that's the programme... but no start date specified.
[1] Edit: I meant to say Digital Effects filters, not De-Emphasis filters.Last edited by mrw; 2012-07-02 at 10:58. Reason: Clarification
