Hi, From: Kai Vehmanen eca.cx> Subject: Re: [ecasound] Recording and monitoring Date: Tue, 25 Nov 2008 23:41:51 +0200 (EET) Indeed I get following message : WARNING: ALSA playback underrun, glitches in audio playback possible .... It seems that I can correct this problem by passing -f:16,2,48000 and -z:intbuf options to ecasound. I saw that somebody did that by reading the mailing list archive.

Re: cs-save writes the wrong loop syntax

Linux Media — 2008-11-29T01:58:13

For me, both cs-save and cs-save-as write the file incorrectly, leading to inability to run the ECS file The original... -i:loop,101 -o:loop,101 Both cs-save and cs-save-as versions (both write the file the same)... -i:"loop,101",101 -o:"loop,101",101 I notice that if you just delete the quotes, both of these will work... -i:loop,101,101 -o:loop,101,101 (and) -i:loop,101 -o:loop,101 Thanks, Rocco ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Ecasound-list mailing list Ecasound-list< at >lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ecasound-list

cs-save writes the wrong loop syntax

Dubphil — 2008-11-28T23:53:32

Hello ! last stable version of ecasound 2.5.2 As says the subject, cs-load doesn't write correctly the loop syntax : it writes it like that : -i "loop,1",1 and this syntax gives an error to ecasound at load. I must edit the file to change like this : -i "loop",1 Regards Philippe ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Ecasound-list mailing list Ecasound-list< at >lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ecasound-list

Hi, Julien second solution works. From: Kai Vehmanen eca.cx> Subject: Re: [ecasound] Recording and monitoring Date: Tue, 25 Nov 2008 23:41:51 +0200 (EET) Not clear to waht it corresponds on my card. I have an onboard chip essentially intel ich9. Hum, if I enable the line playback I am not sure that what I hear is waht is actually captured. In fact when modifying capture volume it does not change anything in what I hear. That's why I whanted to use ecasound to monitor actually what is being recorded. Hum I don't see to waht it corresponds on my own chip. Yep but line playback is not capture playback in my opinion. I mean taht I can hear small sequences of sound of half a second separated by blanks ! As if playback were continuously interrupted. When using a loop as recommanded by Julien this problem does not occur any longer.

Hi Julien, Before asking my question I read the tips you wrote about these subject. Thanks for this work but I did not find any answer to this particular question in them. From: Julien Claassen c-lab.de> Subject: Re: [ecasound] Recording and monitoring Date: Tue, 25 Nov 2008 11:01:16 +0100 (CET) Things might be easier but I suspect with less understanding of the process.Moreover I'd prefer not to install jack on my system if things might function without it. up to the syntax which is not completely correct : ecasound -a:1 -i alsa -o loop,1 -a:1,2 -i loop,1 -a:2 -o alsa -a:3 -o file.wav It works. In my opinion that's precisely the point were things are not completely clear : What correspondance between alsa hardware naming in ecasound and sound devices. If I get understand this point I'll try to write something. Anyway I suspect that it might be hardware dependent. Thanks, Pierre ----------------------------------------------------------------

Hi, On Mon, 24 Nov 2008, Pierre Lorenzon wrote: the best way is to enable analog loopback (aka HW monitoring) from alsamixer (this is supported by most soundcards). This way you hear what is being recorded with almost zero delay. For instance on many consumer sound devices, you need to unmute the "Line" control in "Playback" section of alsamixer. On my M-Audio Delta44, I need to set HW outputs to "Digital Mixer" (also in "Playback" section of alsamixer). To verify whether you have the right mixer settings (for hw monitoring), you should hear the live input played back on the outputs even though ecasound is not running. That should work though. There will be some more delay than with hw-monitoring, but it should work. What do you exactly mean by sound "splitting"...?

Compiling Ecasound for amd64

Hi! You have at least two alternatives, that I can see. 1. Use JACK, makes a lot of things easier: jack_connect system:capture_1 system:playback_1 jack_connect system:capture_2 system:playback_2 # your souncard inputs are connected to your outputs, that's the monitor. ecasound -c -a:1 -i jack -o out.wav ecasound ('h' for help)> engine-launch jack_connect system:capture_1 ecasound:in_1 jack_connect system:capture_2 ecasound:in_2 Now just start recording. The same goes for softsynths, just exchange your system:capture_N to the corresponding port of your softsynth (fluidsynth, LinuxSampler, aeolus, etc. etc.) 2. Use loop devices: Not 100% sure, but 99%: ecasound -a:1 -i alsa -o loop,1 -a:2 -i loop,1 -o alsa -a:3 -i loop,1 -o file.wav About your alsa IO see the ecasound manual, there you find a bit about ALSA device naming with ecasound. Also have a look at the alsa-wiki at alsa-project.org. HTH. Kindest regards Julien -------- Music was my first love and it will be my last (John

Recording and monitoring

Pierre Lorenzon — 2008-11-24T19:50:31

Hi All, Sorry if this question was already answered many times on the list and simply tell me where is a good hint if necessary. I would like to monitor what I am recording with ecasound. Hence I used following command : ecasound -c -a:1,2 -i alsa \ -a:1 -o alsa -a:2 -o file.wav But it doesn't work : the sound "splits". I suspect that I should use to separate alsa devices to record and monitor but I do not see how to proceed. I think that it worked in the past with oss but oss is no longer installed on my system.

Re: Bug saving to mp3

Carl Welch — 2008-11-13T17:40:24

Hello everyone, I am hoping to build a server-side app that will take multiple mp3 and mix them down to one single file. I was planning on using the php version of ecasound, but noticed it was many years old. After finally finding the newest version of ecasound, I was bummed to find there was no way to build a php extension or shared object (not that I even know how to do that) - I did notice that there was Rubyecasound. Now, I have zero experience with ruby. Is there any tutorials on how to implement that? or is there an easier way to do deal with ecasound on the server-side? Can anyone point me in the right direction? PLEASE?!?! thank you, in advance.

Hi Carlos, Am Donnerstag, den 13.11.2008, 05:58 -0200 schrieb Carlos Pita: the exact lame command ecasound uses to encode mp3 can be configured in .ecasound/ecasoundrc. Have a look at this file (and man ecsaoundrc) and find out whether this command also fails when issued on the command line. Maybe ecasound cannot find lame in its path. You could try to add the absolute path to ecasoundrc.
