[arm-allstar] rx audio capture - recording

Mon May 18 14:23:27 EST 2015

Neil,

 I am not sure exactly what you want to do but there is a way to capture all received audio. It is not recommended on the BBB or RPi2 because it takes up lots of space and would need to be recorded to the SD card unless you had a USB stick or USB hard drive installed or for a limited amount of time recorded to RAM using the /tmp directory.

The command is archivedir=    and this points to the directory where you want to store the audio. It is then stored in a directory below that with a name of the node number. Each transmission is in a separate file. archivedir= is entered in rpt.conf in the node section for the node you want to record.

tts_audio converts text to speech and would not make any sense to work with an existing audio file. It cannot convert speech to text.

You could turn on the audio archiving for a limited amount of time on the BBB or RPi2 but make sure you use the /tmp directory which stores it to RAM not the SD card. Then you could play back the file and listen to the audio quality.
If you do store it in /tmp make sure you delete the file after or reboot. /tmp files do not survive a reboot.

Subject: Re: [arm-allstar] crontab editing on BBB asterisk v1.2.1 and rx	audio capture - recording

Chris and Fred and others....
I got crontab modified ok but still do not know the name 
of the system profile filename to make the default editor choice permanent. I am 
running on a beagle bone black asterisk v1.2.1

Also is there a script or function that can record 
received audio and then let me pipe it to TTS_Audio.sh
the idea is to create a dtmf callable function 
macro  that captures received audio on the local simplex rf frequency, 
convert it to digital audio and plays it back. The cats meow implementation 
would help simplex link users set their audio properly

"export" will only carry the shell variable till the next time 
the shell is restarted, or the system rebooted, to make it permanent, it needs 
to be placed in your profile (you only) or the system profile if you want it to 
apply to all users. 

Not knowing what shell you are using.. something 
like 

echo "export EDITOR=nano" >> ~/.bashrc

will make it 
permanent.  The name of your profile file will change depending on what 
shell you are using.. .  Run a "ls -a" so you can see what hidden file you 
have in your home directory..  Fred

  Hi Neil,

Use  the following command to set your default browser: 
    export EDITOR=nano 

  This will allow you to set the editor of your choosing.  If you used 
  contab -e, it will use this edtor.  When the crontab is saved, the syntax 
  is checked and valided before saving.  You will not need to restart 
  crond, as it will pick up the entries when they are saved.

  Another userful crontab command is:

  crontab -l    

  This lists the crontab entry.
