[SlimDevices: Radio] Simple EQ?
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?

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.

Re: [SlimDevices: Radio] Simple EQ?
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.

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 ? A couple of months ago I formed the conclusion that the hardware codec/amplifier/thingummy could be induced to do some filtering. 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). 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. :) mrw's Profile: http://forums.slimdevices.com/member.php?userid=38299 View this thread: http://forums.slimdevices.com/showthread.php?t=95659 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
Re: [SlimDevices: Radio] Simple EQ?
A server plugin is alway possible :) The existing ones are inguz, wich does not seem to be maintained anymoore and I'm unsure about it's support for other OS than win ? Not user friendly ,complex . Then some are using brutefir , which seems really geeky . A simple eq plugin would be a real success . That will only help those with a local server thou , afaiu the radio itself does not have a built in DSP ( boom has ) and the CPU can simply not run any high quality filters .

I got Inguz to work on my Win7 PC, but it was a bit of work. And Inguz is brilliant when it works. So I believe that a user-friendly install wizard and a front-end for Inguz would have been better than a brand new EQ plugin, in many ways.

But the codec chip does have some accessible filter controls that might be employable in a simple way. I figured out (can't remember how) that it is a Texas Instruments TLV320AIC3104. I don't know what variant. As proof of concept I fired up ssh, figured out (yet again) how to use 'amixer', and dug out the datasheet. To read the current state of the Audio Codec Digital Filter Control Register: Code: amixer sget 'Audio Codec Digital Filter Control' Output therefrom: Code: Simple mixer control 'Audio Codec Digital Filter Control',0 Capabilities: volume volume-joined Playback channels: Mono Capture channels: Mono Limits: 0 - 255 Mono: 0 [0%] As you see, mine returns value '0', i.e. all off. I assume that this the standard, default, configuration of the Radio. To turn on each DAC's Digital Effects Filter Control: Code: amixer sset 'Audio Codec Digital Filter Control' 10 To turn off - back to defaults: Code: amixer sset 'Audio Codec Digital Filter Control' 0 I can hear it act as the default filters are switched in and out. So my programme now advances one step further: a) Figure out values for the Digital Effects Filter that will give useful adjustments. b) Figure out how to engage/disengage them on demand. (a) Requires a bit of education on how to calculate filter values. (b) An installable applet. Perhaps suborn the volume control mute action into doing a little more than just 'mute'. I think something may be doable, provided it's kept simple and not required to be perfect under all conditions. mrw's Profile: http://forums.slimdevices.com/member.php?userid=38299 View this thread: http://forums.slimdevices.com/showthread.php?t=95659 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio

I have no great knowledge of these things, but they typically offer themselves as 'solutions' for low power audio devices, and have a number of built-in processing paths for inputs and outputs, volume control, equalization & sound effects, etc. The Radio seems to use one channel of the chip to drive the bigger speaker and the other channel to drive the smaller speaker.

Hey Soulkeeper, how did you get Inguz EQ to work?? I have been playing around with the InquzDSP.exe and the EQ installation and I cannot seem to get it to work on my win7 at all. I can access the EQ controls but they just don't impact the sound and i know inquzDSP.exe is not running as a process. It doesn't seem to want to start up...? Quite frankly, I will have to return my squeezebox if I cannot get it to work with EQ. My goal is to have it hooked up directly to a hi-quality wireless headphones set from Sennheiser (RS 220). When comparing it to my Asus Audio Essence ST card with build in DSP the squeezebox sounds just so flat and not worth the money. I am really stressing out about this because I am trying to set this up for my dad retirement gift, and now I guess the best I can do is give him the headphones hooked up directly to the PC and hope the range is good enough to transmit the signal two floors :/ ANY help is greatly appreciated... amsync's Profile: http://forums.slimdevices.com/member.php?userid=56587 View this thread: http://forums.slimdevices.com/showthread.php?t=95659 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio

He he the OP is me for that bug , I was just amazed that they omitted tone controls when the Squeezebox BOOM had it, that and a real snooze button and backlit buttons ? they know how to do such a device and then they don't ?

I've never seen a Boom. I do think the Radio sound quality is very good, without tone controls, and I am very content with it. It's really only a few programme sources that I think could be improved.

Yeah, I've been scratching my head over that too. The Radio is a good device in my experience & opinion, but cutting out those three functions..? I understand that all of them would increase the price, but as it is, the Radio is neither fish nor fowl.

Re: [SlimDevices: Radio] Simple EQ?
Resurrecting an old thread here, but I've got a somewhat similar situation. I've re-purposed an old Squeezebox 2 to our sunporch and have a pair of small advent indoor/outdoor speakers driven by a T-Amp. It drives two pairs - one pair in the sunporch, and another pair out on the deck. The sound is decent for our own material, but often times the source material from internet radio is stripped of any bass content. I'd love to be able to boost up the warmth a bit. This is just background music, so I'm not concerned about any audiophile concerns. ;-) Any ideas at all? I guess it would be easiest to switch out the T amp with one that has bass and treble controls. Pyle has some mini-amps that have these via PartsExpress.

One way of filtering would be to invoke an extra SoX command in custom-convert.conf, with the appropriate filter parameters. Then you'd first have to experiment a bit to find suitable filter parameters, so it won't work if you need to be able to change it on the fly. If you're on Linux you could use the plugin BrutefirDRC, or just BruteFIR raw. Same amount of experimentation needed. But yeah, replacing the amp would be easy. And it enables instantaneous change.

Re: [SlimDevices: Radio] Simple EQ?
I'm not an expert on usage of SoX but I think the contents of the custom-convert.conf file would look something like this and the file goes in the same folder on your server as your convert.conf file. Code: mp3 flc * * [sox] -t mp3 $FILE$ -t flac - bass +6 250 wma flc * * [sox] -t wma $FILE$ -t flac - bass +6 250 Set up this way it only affects MP3/WMA (e.g. radio streams). Play with the boost (set at 6 in example above) and center frequency (set at 250Hz). If you want to have this change be specific only to that player, switch out the second * with the MAC address of that unit. http://sox.sourceforge.net/sox.html Apesbrain's Profile: http://forums.slimdevices.com/member.php?userid=738 View this thread: http://forums.slimdevices.com/showthread.php?t=95659 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
