[RDD] Weather and Time Announcements
This station I am moving to Rivendell is currently running on a Windows system. They somehow download the local weather from a NOAA site and cull the local temperature from it. They have a Windows text-to-speech program that reads the .txt file with the temp and creates a short mp3 file with the current temperature. They have a whole list of mp3 files covering temps from 0-115 degrees. They also have a bunch of time files with 0-12 hours, 0-59 minutes, and am/pm. I can't seem to find anything in the existing Windows computer that actually performs this function. The previous engineer who set all this up basically evaporated leaving no documentation. The current staff knows it happens, but no idea how it works. I found the time and temp audio files and an exe text2speech app, but nothing else. Is there anything in Rivendell or Linux I could use to provide this functionality? -- 73, Michael WA7SKG "Any day you do not learn one new thing is a wasted day." ___ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
Re: [RDD] Weather and Time Announcements
Hi Michael, For getting the Time part, one way that I looked at in the past (but never implemented due to the work requried) is to record an audio cut for each minute of the day. To cut down on the amount of recording it is possible to re-use the AM and PM recordings if you don't specify AM or PM in the audio. So for example, you could use the same audio for saying "It's 12:42" for both 12:42 am and 12:42 pm, leaving it to the listeners to figure out if it is AM or PM. You'll want to make 2 carts, one for AM and one for PM, each with 720 cuts of audio representing each minute of that time block. Daypart each cut for the minute of time that it represents. When you want the time of day to play on the air, just schedule the appropriate cart (or both carts back to back). It'll only play the cut that is dayparted for that specific minute. It takes a bunch of effort to get this type of thing set up, but once set up it should just work. Furthermore it is all internal to Rivendell so if someone needs to figure it out in the future it should be fairly straight forward to figure out.

Yup, the only reason I recommend doing 2 carts - one for AM and the other for PM - is because there is a limit of 999 cuts per cart, so it isn't possible to load the full 1440 cuts into a single cart.

As you explain, this script requires all the "raw" audio files to previously exist (preferably in WAV format, but that's not a hard requirement). My script is attached to this message, and is also available at https://github.com/opensourceradio/ram/blob/master/usr/local/bin/btd-time-temp It uses a few ZSH-specific things, as well as ffmpeg(1) to concatenate multiple audio files together on the fly. And it uses xmlstarlet(1) to parse the output and extract the current temperature from the US National Weather Service current conditions XML feed. This command installs the basic requirements: sudo yum install -y zsh ffmpeg xmlstarlet Current(ish) FFMPEG packages are hosted at the Nux Dextop CentOS repository. More details at http://li.nux.ro/repos.html Activate the script using your favorite timed job scheduler (e.g., cron, systemd, etc.). In order to be timely, I recommend running the script every minute, but you can adjust the frequency to match your scheduled "time and temp" Events in your logs. Since they are updated hourly, the script fetches the current conditions from the NWS only once per hour regardless of how often you run it. Complete setup documentation is in the script comments. Usage documentation is available with "btd-time-temp --help".

It never even occurred to me to load all the time cuts into a cart and then daypart each cut. Fabulous! Thanks for this! I'm also playing with festival(1) and flight(1) to get the times and temperatures pre-recorded with voices sounding as human as possible with a synthesizer. Of course, nothing beats real, actual human voice recordings, but there are some pretty nice sounding "fake" voices available these days... ~David Klann broadcasttool.com >> >> This station I am moving to Rivendell is currently running on a Windows >> system.

I have a set of such times which were easy to ingest once recorded, because we labelled them 0601.wav 0602.wav etc.using rdimport we set the start time and end time from the filename. In fact the times were set 30 sec before and 30 sec after. The voice used was the 'host' of that segment. Bit of work to record and label, but once done they last forever. To avoid repetition we made some variants on the ones that seemed to be played more often. If the cart is in the VTRAX group they can be laid over song intros. Bit of work but it's worth it.
