So as I understand it, ecasound -D -z:nodb -f 16,2,44100 -i stdin -eli:1030 -b 4096 -ev -x -f s16_le,2,88200 -o alsahw,0,0 will accomplish what you want. In other words, ecasound will perform sample rate conversion automatically just prior to output. Is there a reason to think this *isn't* doing what you want? Regards, Joel </pre> Joel Roth 2013-05-16T23:28:35 http://permalink.gmane.org/gmane.comp.audio.ecasound.general/4463 <pre>Hello, I have the following command line: ecasound -D -z:nodb -f 16,2,44100 -i stdin -eli:1030 -b 4096 -ev -x -f s16_le,2,44100 -o alsahw,0,0 which works as expected. 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 ?

Complexity of code is less of an issue becuase it only needs to be set up once and that can be before a performance. I just don't want to have something that is hard to setup and take down form a gear perspective. I own my own PA and for smaller gigs I might grab a combo amp with mic in-put. I'm not married to Ecasound, I took a cursory look at nama. If you think that is the right approch I'll dig deeper into it. I've never written in perl, I'm a pythong guy, but I could probably hack something together with a few tutorials. </pre> Daniel Worth 2013-04-18T13:24:01 http://permalink.gmane.org/gmane.comp.audio.ecasound.general/4459 <pre> Hi Daniel, I read your post on LAU, you mentioned using Raspberry Pi. When you said shell scripts and Ecasound, I thought maybe you wanted something minimalistic. If you want to control Ecasound, Nama gives you a fairly powerful leg up. To the point that implementing what you want in Nama, might be easier that trying to build it from scratch, assuming some facility with Perl. Nama would need two things: 1. A way to trigger actions on detecting MIDI events AFAIK Ecasound can only use MIDI to control effect parameters. CPAN does have a module, https://metacpan.org/module/MIDI::ALSA, which is based on some python and lua libraries. What kind of response time would you would need? The user would have to configure a table of midi events, and the corresponding actions. 2. Playlists The playlist could be separate tracks, or a set of marks within a single track. (Having both would be nice.) And with that a few commands for navigating around the playlist. Our current style would be to implement playlis</pre> Joel Roth 2013-04-18T05:43:14 http://permalink.gmane.org/gmane.comp.audio.ecasound.general/4458 <pre>Hello Daniel! I am pretty sure, that the simple answer is no. Ecasound can interact with some MIDI, but there are no position controls attachable to MIDI. But youmight use OSC. I think there are applications to map MIDI to OSC. But since I've never been tempted to go live - as on stage - I don't know. Perhaps Kai or Joel have more info. I know, that there were a few people coding successfully with python, creating interesting applications based on Ecasound. Sorry, I can't be more specific.

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://permalink.gmane.org/gmane.comp.audio.ecasound.general/4456 <pre>Hi, On Mon, 8 Apr 2013, rocco wrote: oh yes, right object is removed but the remaining connections may be stale now.

I would like to make an assessment based on several days of working with this. When you have all objects of the same name, then regardless of what a(oi)-index-select that is issued, it simply ignores that request and chooses the object that was last created. I tested this by creating a new chain and attaching an input object to it. Then I chose the index of a different input object. It ignored the request and removed the last input object that was created. Remember, the (above) scenarios exists when all the objects have the same name. But when there's (either) all unique names (or) a mixture of same object names and unique object names, then it behaves in less predictable ways, sometimes removing the last created object and sometimes actually rearranging the chains and objects in strange ways.

But still, I am not sure Ecasound is to 100% to blame. You need to either (a) remove the output side of chain as well, or (b) add an input to replace the one you removed. That's why when you asked Ecasound if cs-is-valid, it said '0' i.e. "no". And Ecasound gave you the reason, even though it reported the wrong chain. If you're removing the input, then why not remove the whole chain? c-select 2 c-remove Finally, if you ask cs-is-valid, and Ecasound returns 0, then it means that cs-connect will *not* work. Which is exactly what happens below. So to repeat myself, I think you need to make sure you provide a valid chain setup. Ecasound's behavior is well defined only in that case. I don't have much experience using IAM for creating a chain setup. I use interactive commands only to add/remove effects and to start/start/move the playback head. For my purposes, I found it clearer to write the e</pre> Joel Roth 2013-04-03T05:30:58 http://permalink.gmane.org/gmane.comp.audio.ecasound.general/4449 <pre> I was very hopeful because you're a pretty smart guy. But unfortunately, I've had the same result using your suggestions. Just to make sure I was implementing your suggestions correctly, I've added my session below.

By just removing the one input, you have an invalid chain setup. That causes weird complaints when Ecasound tries to reconnect it, (I seem to recall Ecasound performs poorly at providing meaningful information from a broken setup.) So I would try this: cs-disconnect (modify chains) cs-is-valid # should return 1 cs-connect Hope this helps. Joel </pre> Joel Roth 2013-04-02T17:36:16 http://permalink.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...
