Re: [Debian]Voice recorder - ecasound -- Help
Ok. thanks for your great help. For now, I choose the simplicity and * use the state files provided with the fr * use the -D plughw:0,0 option to record only a mono file and use -r 8000 to record at 8khZ So my line becomes: arecord -D plughw:0,0 -r 8000 $userfolder/$myname This saves a lot of space : 2MO -- 100 kO for a 10 seconds record.

Hum, is it a question, or a statement ? I personally don't know. If it is worse, is it much worse ? I recall this is to record voice, not a concerto.

This is why when you open a wav recorded file with audacity, you can see the 2 left and right side, but only the right has data... This is not good. Have a look at controls 66 and 67. Depending on how your state file routes the mic input, set them both to right or left. Example: $ amixer sset 'Capture Right Mixer' 'Analogue Mix Right' $ amixer sset 'Capture Left Mixer' 'Analogue Mix Right' (Why do we have both? They are forced to the same value.) Then select the same ADC as capture source for both channels (control 51): $ amixer sset 'ADC Data Select' 'Right ADC' I have attached two state files, one to capture from the headset mic and one to capture from the handset mic. Both use automatic level control and the one to capture from the headset mic also uses the noise gate (squelsh) control. The signal level at the handset mic is unfortunately too low for that. Please also refer to the wiki as there are a _lot_ of ways to route sound to and from various places with the WM8753L: https://wiki.openmoko.org/wiki/Neo_1973_audio_subsystem It would be really great to have a mixer app where you could point out the controls on a diagram such as the one on the wiki page. So if someone knwos the parameter to put in arecord to record only one mono sound, this would help ! -c 1, but the WM8753L doesn't support mono. You can work around it by using '-D plughw:0,0' instead of '-D hw:0,0'.

When finished, press on s to stop then q to quit. I tried to open the mynotes.wav file with *audacity*, but I cannot see any waves, though my file size is 4Mo/ So my conclusion is ecasound worked well, but I should have change the scenario (one of the *.state file ) before recording ? So I need your help to test ecasound and report any solution. If I can get it to work, I will try to create a simple gui to run it Thanks in advance Kimaidou ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hi both Thanks for you replies. I dumly forgot to search for voice recording among the wiki :( Before I try it, could you please tell if the following order and commands are ok (don't want to break my kernel** cd /usr/share/openmoko/scenarios/ wget http://wildsau.enemy.org/~moko/voice-recording.state arecord -D hw -f cd -v -t wav ~/rec-$(date +%Y-%m-%d-%H-%M).wav alsactl -f voice-recording.state restore HERE I TALK OR SING A SONG : La la laa laa l, then killall -TERM arecord alsactl -f gsmhandset.state restore Is this correct ?

Re: [Debian]Voice recorder - ecasound -- Help
2009/2/19 kimaidou kimai...@gmail.com Hi community I am running the Hackable1 , and try to find a lightweight and simple way to record and play voice notes. I discovered ecasound via a google search. ( http://groups.google.com/group/linux.debian.user/browse_thread/thread/d2caa54f7448993a/14d58b5ea003409a?lnk=raot). I am trying to use it from command-line to record some sound (me talking :D ) with the following line : *ecasound -i /dev/dsp -o mynotes.wav -c* Pressing on t will start recording. When finished, press on s to stop then q to quit. I tried to open the mynotes.wav file with *audacity*, but I cannot see any waves, though my file size is 4Mo/ So my conclusion is ecasound worked well, but I should have change the scenario (one of the *.state file ) before recording ? So I need your help to test ecasound and report any solution. If I can get it to work, I will try to create a simple gui to run it Does arecord and aplay work for you? http://wiki.openmoko.org/wiki/Recording_audio ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: [Debian]Voice recorder - ecasound -- Help
Come back here to give some feedback :
1/ to restore one state file, you must specify the complete adress e.g.
alsactl -f /usr/share/openmoko/scenarios/gsmhandset.state restore
2/ I tried once to record via arecord and it worked (no sound because I have
not done the 1/ ). Then I killed it by CTRL+Z
But now I cannot reuse it, the command
arecord -D hw -f cd -v -t wav ~/rec-$(date +%Y-%m-%d-%H-%M).wav
give the following error :
arecord: main:564: audio open error: Device or resource busy
How can I de-busy the audio device ?
Thanks in advance

Re: [Debian]Voice recorder - ecasound -- Help
Hi All. My feedback : the process is working. Now I would like to create a small bash + zenity tool. I need anyone's help to make it work. For now, I have : #!/bin/bash zenity --question --title=Voice-note --text=Click Validate to START recording; gostart=$? if [ $gostart = 1 ] then echo Operation canceled exit else echo Recording... fi zenity --info --title=Voice-note --text=Click Validate to STOP recording; gostop=$? arecord -D hw -f cd -v -t wav ~/rec-$(date +%Y-%m-%d-%H-%M).wav alsactl -f /usr/share/openmoko/scenarios/voip-handset.state restore alsactl -f /usr/share/openmoko/scenarios/gsmstereoout.state restore killall -TERM arecord zenity --info --title=Voice note --text=Your voice-note has been recorded; goread=$? This is not working because I don't know how to load the arecord thing AND show a windows which asks the user to stop recording. Does anyone have any clue ? thanks in advance kimaidou ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: [Debian]Voice recorder - ecasound -- Help
I am answering myself here : I found the solution :you have to add a at the end of the arecord line So the file content is now : #!/bin/bash zenity --question --title=Voice-note --text=Click Validate to START recording; gostart=$? if [ $gostart = 1 ] then echo Operation canceled exit else echo Recording... fi arecord -D hw -f cd -v -t wav ~/rec-$(date +%Y-%m-%d-%H-%M).wav alsactl -f /usr/share/openmoko/scenarios/voip-handset.state restore zenity --info --title=Voice-note --text=Click Validate to STOP recording; gostop=$? killall -TERM arecord alsactl -f /usr/share/openmoko/scenarios/gsmhandset.state restore zenity --info --title=Voice note --text=Your voice-note has been recorded; goread=$? #END OF FILE CONCLUSION It works well !! For those who want to try, just create a executable text file called voicenote.sh for example in your personnal folder and add the lines above. To make it executable, please do : chmod +x ~/voicenote.sh Thanks all for your help !

good idea. Btw, I have made an ipk and a debian tar file to install my voicenote software.
