It is a part of longer chain, so data is piped into stdin. I want to do two things: 1) replace 's16_le,2,44100' with 's16_le,2,88200', i.e to make ALSA device work with 88200Hz sample rate; 2) insert resampling just before it, but _after_ the LADSPA plugin, i.e. after '-eli:1030'. How can I do this ?

What I'd like to do is set up a live rig for playing shows with a backing track that allows me more flexability in a performance. The goal would be to have a playlist that had each section of the song, as a backing track, and, if I hit nothing plays the song from beginning to end, but if I interact with it I could replay a section or more ideal jump around to other tracks. So if I feel like taking an extended solo or repeating a chorus becuase it just feels right I can, more likely I messed up an need another chance to hit a lyric cue. I have an fcb-1010 midi controller that I would like to use for sending midi messages. Is this possible in ecasound or ecaplay? Any advice would be much appreciated. </pre> Daniel Worth 2013-04-17T17:54:01 http://comments.gmane.org/gmane.comp.audio.ecasound.general/4447 <pre>Quick assessment of the situation, then my complete session... It seems that when there are multiple input objects of the same name or multiple output objects of the same name, 'ai-index-select', 'ai-remove' and 'ao-index-select', 'ao-remove' removes the wrong object. It does (not) seem to have this confusion when the input objects have different names or the output objects have different names. Also, it seems (possibly) that in certain situations, it seems to think it removed the object from a different chain instead of the chain that it actually removed it from. Here's my session...

It is working, but I am running into a bit of a problem getting ecasound to connect to it automatically without using aconnect. I am using Elementary as the widget set from E17 ( enlightenment.org), and have attached the source code to this email. It can be built as follows: gcc main.c -o slider -lasound `pkg-config elementary --cflags --libs` It currently just sends CC events to channel 1, controller 1. I am using the following ecasound command: ecasound -i test.wav -o alsahw -ea:100 -km:1,1,200,1,1 -Md:alsaseq,midicontroller I am grateful for any thoughts on what I am doing wrong in my code.

Here are the two problems, and a snippet of python code I'm trying to use for it: 1)Mixing several chains to one chain as in the example from the docs, particularly the all line, but more generally how to mix two or more chains to a third chain: ecasound -c \ -a:1 -i drums.wav \ -a:2 -i synth-background.wav \ -a:3 -i bass-guitar_take-2.ewf \ -a:4 -i brass-house-lead.wav \ -a:all -o alsa 2)The loop device functionality, not looping like repeating a sample but copying the output of one chain or the mix from multiple chains to one or more chains, as in this example from the docs(I've shortened it a little to focus it): -a:1 -i drums.wav \ -a:2 -i synth-background.wav \ -a:1,2 -o loop,1 \ -a:5,6 -i loop,1 \ -a:5 -o alsa \ -a:6 -o current-mix.wav Here is a snippet of the script I've been playing with to try to get this working with my input with comments for where I've been trying to get this workin</pre> will cunningham 2012-12-10T20:51:37 http://comments.gmane.org/gmane.comp.audio.ecasound.general/4395 <pre>Hello Is it possible to use ecasound's interactive mode to cut/copy and paste, like this?

So for example if the left track has audio at 200Hz the right track will not have audio at 200Hz, and so on up the frequency range alternating for each track. Something like a parametric eq with opposite values for each output track. -- Patrick Shirkey Boost Hardware Ltd ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.

I just came across an error, processing a filename, which had a comma. It said: unable to handle filenames with coma. this must have been ecanormalize or ecafixdc from a script. I renamed the original file and processed again, but it might be nice to not have this issue for a start. If it's not too difficult, could this be fixed? I know, that coma is a seperator for parameters in all operations, but usually it should be shell-escaped or quoted.

Now I have a need to write transcription software (that is playback controlled by foot pedals so a typist can transcribe them.) I have two problems - which are related to each other. Firstly ecasound gives me incomplete playback - which I believe is at least in part due to buffering on the sound card.  I can get around that by adding "silence" to the end of the audio files to be transcribed (although a fix would be rather nice).  In my case the "lost" audio time is significant because I have a need to keep the size of the audio files to a minimum and so am recording 1 channel, 8 bits and 11,025KHz.  "Lost" time depends upon the computer being used (presumably the sound card) but is typically 50 to 100 seconds.  At CD quality recording we would only be talking say 10 seconds or less and for 5.1 etc even less.  I would be interested in knowing if others have this </pre> dougf< at >people.net.au 2012-09-14T08:25:26 http://comments.gmane.org/gmane.comp.audio.ecasound.general/4311 <pre>Hi all, I'm wondering if anyone has put together a chain setup to do multiband compression/limiting, similar to the sox mcompand function?
