I don't think you need more EQ bands. Better install and use for testing first the LADSPA plugins instead of Jamin. Then tell us what you think. I find the solution simple and working great, under Ubuntu also.
Hi arcgotic, I had a look at the LADSPA plugins, I have a quad core PI sat here doing nothing. I did by it to upgrade my single core Pi, but that has been running so well, I wonder if the Quad core would run Jack and replace the Revo?
I don't think the single core would be fast enough!

I'd very much like to know if anyone is running my LADSPA plugins and ecasound on a single core Pi (e.g. Model B+). This is because I am very interested in getting my hands on a Pi Zero and trying that combination for crossover processing...
Deafuser, I run it on a Atom Intel 1GHz cheap Asus Asrock minipc, 6 channels output via USB. It uses 5% CPU. I think it will work on your 4core with no problems.
Charlie,
I've been watching for them, as soon as I can find a few I plan to order some. As soon as I heard about them I thought of your plugins and the possibilities a small platform like this could bring.
I hope suppliers have them again soon!
I heard th Pi single core had a bad jack! Google doesn't give away much on the quad core! Not sure about ecosound

Adafruit has them in stock. I ordered a few to try out.

I haven't had time to test my unit, except to get the OS running and play a streaming radio station using VLC. It should work like the Pi, but has slightly better capabilities in the CPU and ethernet/USB bus.
I'm going to try adding my 1-gig hard drive with my entire connection. The Orange Pi includes a SATA connection.... Good luck to both of us...
Just got 2 pi zero's delivered.
Hopefully will have time to set them up this week and try to test.

Hello, can I ask, how accurate are the plugins? I'm interested in the low pass filters and parametric eq for my IB sub?
Thankyou
Thankyou
Odroid C1+
Hello Odal3,
I have changed focus a little bit in that I am just loading the music onto the SD card in lossless format. I have been able to get the Odroid C1+ to work with a Sewell Soundbox Pro - http://www.amazon.com/gp/product/B00K1OOGRI?psc=1&redirect=true&ref_=oh_aui_search_detailpage
I am running six output channels at CD quality through ecasound in a 5.1 format. I then am amping each of the sub channels, mid channels and tweeter channels to an open-baffle set of speakers.
The audio sounds real good and alive.
Here is the ecasound command: (The song is renamed but is Peggy's Kitchen Wall by Bruce Cockburn)
ecasound -z:mixmode,sum -x \
-a pre1 -i:/home/odroid/peggy.wav -o:loop,1 \
-a pre2,woofer -i:loop,1 \
-a:mid,tweeter -i:loop,2 \
-a pre2 -o loop,2 \
-a:woofer -pf:/etc/woofer.ecp -chorder:0,0,0,0,1,2 \
-a:mid -pf:/etc/mid.ecp -chorder:1,2,0,0,0,0 \
-a:tweeter -pf:/etc/tweeter.ecp -chorder:0,0,1,2,0,0 \
-a:woofer,mid,tweeter -f:16,6,44100 -o:alsa,surround51:Audio
So far, all I have been able to get done is playing a file that is on the USB SD card individually. I want to use a player such as mpd but have yet to figure out how.
I am wondering if I will be able to use a USB harddrive as a source. But, one thing at a time.
If there are any mpd gurus here I would sure love to have a tip or two.

Try something like:
sudo apt-get install <program name>
to install something under linux. I'm not sure what you are running on the Odroid. I just installed mpd and am using the mpc client on the same computer for playback control. These work well imo.
Have you considered buying and mounting a usb external hard drive?
That Sewell Direct Soundbox Pro looks very interesting. How did the installation go? Did you need to find a driver or was it plug and play?
Do you happen to know what the maximum output voltage is from the Soundbox Pro? I couldn't find that spec anywhere...

I was asking about the accuracy of the plugins, because I want to dial my IB sub in and will need to eq out any nasty peeks! Thanks
MPD
Hi Charlie,
Thanks for the reply. I have successfully installed mpd but am learning how to set it up and use it - a challenge. I have given up on trying to ask the card to take a line in and then output it after processing with ecasound.
I am now trying to set up the card as a server output with mpd. But, I do not know mpd at all.
As to the USB card, it is pretty cool and has a good DA converter in it.
The Sewell is actually a rebranded version of this:
aim - Audio & Wireless Solutions
It uses a C-Media CMI-6620 chip with standalone HD Audio Codec CM9882A.
That chip is not listed on the ALSA matrix but it was recognized P&P by my linux setup.
Speaker test works normally and ecasound works too.
Changing its settings fails on alsamixer unless you put "options snd-usb-audio ignore_ctl_error=1" into the /etc/alsa-base.conf file.

What did you try in that regard?
You should be able to do something like this in ecasound
ecasound -i alsahw,x,y
Where the bolded x and y are obtained using the command arecord -l (lower case "L" as the option). For instance on my Pi 2 with a Behringer UCA202 connected I see the following:
So in my case I would start the ecasound command string like this:
ecasound -i alsahw,1,0
Likewise you output to the DAC via alsa as well. You are probably more familiar with that end of the chain. Note that the soundcard must be "full duplex" meaning it can simultaneously read and write over the USB bus.
Try that (if you did not already).
Alsa
Hi Charlie,
I tried the -i:alsa,hw😀evice with the USB cards but it just does not work. It just freezes. I believe this may be because the card is not wholly supported by ALSA. CMI6602 does not appear on the ALSA matrix as supported.
That said, I can get -i:some.wav,hw😀evice to work so long as the .wav is on the SD card.
I have not tried the arecord -l but use aplay -l and aplay -L to figure out which card is which.
It worked very well with my big Linux box and a Delta 1010LT card.
I am trying to see if I can use RuneAudio. I will need to change the mpd.conf file (something Rune docs say not to do.).
