Why do you want to use ECASOUND?
Can be done in ALSA - asound.conf, just as easily.
You've not mentioned anything esoteric yet.
Hello Jerms, I'm using Ecasound because I don't know about asound! If its just as easy, I can use either method. Seeing as I've got audio playing, all I need is to set filters to my sub.
What would you like me to mention thats Esoteric?
Thanks

I'm not familiar with R.Taylor's LADSPA plugin input format, so you might have an error with that. If you insert -ddd right after ecasound you will get a lot more information that you can scroll through and try to find the source of the error. You should be able to run the command "analyseplugin" (note spelling) followed by the plugin name at the command prompt and get info back about the plugin input, etc.
You are welcome to download and install my plugins (see my signature) and then I would be able to better help you.
What are the contents of your pre.ecp and woofer.ecp files? This file should only contain ecasound commands just like they would be typed explicitly in the command string. Are you placing the two RTxxx LADSPA plugin commands in there? The ecp file is just a convenient way to manage lots of commands, nothing more.
Also, you mention you want to EQ a subwoofer. Are there THREE channels that you need to produce: left, right, and subwoofer? Please explain in a little more detail how you are planning to route and connect these channels.
Hello, basically I used to use a Behringer DEQ2496 to eq my sub, an infinite baffle using two 15" drivers and a single mono amp! The Behringer seemed wasted, so it eqs my stereo speakers. I bought a Raspberry Pi 2 and a 3.2" lcd. I used to run Jackctl and Jack-Rack with plugins to do eq. My cooker failed recently and the main RCD tripped, completely shutting off power, upon reboot, my sd card was corrupted and I try to install Jack-Rack, but it won't load. Saw Richard Taylor's site whilst browsing the www looking for an alternative.
I would actually need one mono channel to drive my sub. Line in, lowpass, eq and line out.

OK... First and most important question: have you identified the "line in" (analog input) on your Raspberry Pi? As far as I understand, there isn't one.
Hi, I was using a Behringer UCA202 usb soundcard!
https://www.amazon.co.uk/Behringer-UCA202-U-Control-low-latency-Interface/dp/B000KW2YEI
https://www.amazon.co.uk/Behringer-UCA202-U-Control-low-latency-Interface/dp/B000KW2YEI
I installed ecasound on my laptop, if I get everything running on here, just copy and paste everything as a text file. Ecasound is loaded on PI! I've managed to play mysong.mp3
Perfect! That is about the only analog input that is affordable and reliable for the Pi.
Do you want a single mono input and mono output, stereo input mixed to mono output, or stereo input stereo output?
Also, please list all the crossover and EQ filters that you want to run.
I will come up with the ecasound commands for you and then you can try it.
It would be nice if you installed my ACD plugins (let me know if you do). It's the same kind of thing as Richard's plugins - you download the file, unpack it, then run make and sudo make install in the directory.
Hi, I'd would like stereo down to mono, was going to figure that later, but I guess I could incorporate that from the start. My mains roll off at 80hz, they are reflex bookshelf units from Monitor Audio- MA7's from way back when. So I guess a crossover, a lowpass will be required. I have my infinite Baffle installed between my lounge and kitchen! I'm forever running EQWizard to try and measure my sub. I've built the manifold out of a skin of 18mm.ply and 18mm mdf. My two 15"s run off of a 450 w rms amp. I'm doing this probably *** about face, but I love sub bass and had to put this thing together. Running REW and getting my head round the plots has been a challenge. I dial out the peeks and it sounds terrible. I'm supposed to use a roomcurve, which I believe is done by test tones that make 100hz and 30hz have the same loudness. I did measure from my sweetspot, but someone told me I'm supposed to measure the sub not the room! I believe once I've figured this out, I will need some parametric filters! Lastly, I guess, mono out! What do you think?
Thanks
Thanks
I have referred to the RT plugins info found here:
Richard Taylor -- Thompson Rivers University
when making the ecasound ecp file below. I have not tried these, and don't use his plugins myself, but it should work.
You will need to know the ALSA device info for your Behringer UCA-202. You get this by typing aplay -L at the command line. My UCA202 shows up with the card name "CODEC" under both aplay and arecord, so I assume that yours does too.
Then you can use something like this in ecasound:
What is the above doing?
LINE 1:
On line 1 I set up global parameters for buffering and mixing and specify verbose output with the -ddd option.
LINE 2:
On line 2 I create a new signal chain called "get_input". I then specify the chain should have a format of 16 bits, 2 channels, and a sample rate of 44.1kHz. Next I tell the chain to connect to the alsa device specified by the name "CODEC" to get the data. Then I tell it to mix all channels into the first channel. Finally I send the chain data to an ecasound loop device called "mono_signal".
LINE 3:
I create a new chain called "do_filters". I specify the input to the chain should be the output of the "mono_signal" loop device. Next I tell ecasound that all the filters and EQ functions in the file sub.ecp should be applied to the chain (see below). Finally I send the chain data to another ecasound loop device called "filtered".
LINE 4:
I create another chain called "send_to_DACs". I specify that the input of this chain should be the output of the "filtered" loop device. Next I set the chain format to have the same bit depth and sample rate, but two channels. Then I copy the first channel (channel 0) into both the first and second channel of the chain. Finally I output the audio data to the DAC by device name.
Now you need to specify what crossover filters and EQ/PEQ to use, and the gain adjustment. These will all go in your sub.ecp file. It should look something like this:
What is this doing?
-eadb:X adjusts the level by XdB. X>0 increases the level, X<0 decreases the level. Tweak the gain until you feel the amount of bass is what you want.
-el:RTlr4lowpass,80 is a 4th order low pass LR4 crossover filter to match your mains rolloff
-el:RTparaeq,-6,30,4 I just made this up. It's a parametric EQ filter that takes three parameters: gain, frequency, and Q. Change these to suit.
-el:RTparaeq...(etc) This is an example of the next PEQ band you want to apply. I assume you will use several. Just list them in any order in the ecp file.
Just put everything on one line in the ecp file. The ecp file must be in the same directory in which you issue the ecasound command because there is no path info for it.
So give that a try and post about the result, success or fail. We might need to debug a little. I hope you can display the output on something better than a tiny LCD screen! You can SSH into the machine from a desktop computer and get more screen real estate for instance.

OK, let's start fixing the errors. First up, I made a mistake with "mono signal" in the ecasound script, line 3. Please change
to this
Then re-run and post any errors that pop up.
Code:
-i:mono_signal
Code:
-i:loop,mono_signalThen re-run and post any errors that pop up.
