After the Show

Once the show is over make sure you have a Backup of the entire show so we can put it online on the radio ara podcast.

No need to edit the show to remove commercial music as long as the podcast is hosted at radio Ara server.

Encoding

  • Cutting by Germain

If the show needs to be cut by Germain, encode it at 256 kb/s with CONSTANT BITRATE, as otherwise he cannot properly use his toolset which does not support VBR. The replay gain option calculates the volume for radio transmission (AFAIK). (The recording device in Studio 2 is set to limit the recording to -2.0 dB, so it would be a good idea to amplify the recording to 0dB.) 

-$ lame --replaygain-accurate -h -b 256 --cbr in.wav LetzHack_epX_2012mmdd.mp3
  • Cutting yourself

Just use fancy audacity and edit as you like.

Remember: it's audacity, save often!

When done, normalize the audio:

  1. Effect->Normalize...
  2. [x] Remove any DC offset
  3. [x] Normalize maximum amplitude to
  4. -[0.0]dB
  5. [OK]

(this takes about 1 minute on a good PC)

When encoding for the podcast: use the artist, title and date flags! (is there a podcast genre now?--Tschew 08:02, 1 October 2009 (UTC))

Setting some variables will make the following steps just cut & paste into your bash prompt 

InputFile=        # mp3 or wav file with the ready cut show
MyName=""         # who are you, not filling this will simply use your current user login
EpisodeNumber=    # put episode number here, e.g. 65
EpisodeTitle=""   # title of the show, e.g. "Events Review" (write " as \")
EpisodeDate=      # date of broadcast, e.g. 20120414

# calc intermediate values
EpisodeYear=${EpisodeDate:0:4}
EpisodeMonth=${EpisodeDate:4:2}
EpisodeDay=${EpisodeDate:6:2}
MyName=${MyName:-$(id -un)}
FileName="LetzHack_ep${EpisodeNumber}_${EpisodeDate}_podcast"
TitleTag="Lët'z Hack! episode ${EpisodeNumber} - ${EpisodeTitle}"

# create ogg (oggenc is included in vorbis-tools)
oggenc "$InputFile" -o "${FileName}".ogg -d ${EpisodeYear} -a syn2cat -t "${TitleTag}"

cat << EOF | vorbiscomment -w "${FileName}".ogg
ARTIST=syn2cat Hackerspace
ALBUM=LetzHack Radioshow
TITLE=${TitleTag}
COMPOSER=$MyName
DATE=${EpisodeYear}-${EpisodeMonth}-${EpisodeDay}
EOF

# create mp3
lame -V 7 -v -h --ty ${EpisodeYear} --ta syn2cat --tt "${TitleTag}" "$InputFile" "${FileName}".mp3

You can also use dir2ogg to convert mp3 files to ogg.

Importing

  • Go to the admin page of radio ara podcast server. If you have a password, you have the url (ok it's wordpress).
  • Rename the mp3 file into YYYY-MM-DD-Letz-Hack.mp3
  • Set the mp3tags correctly
    • Title: LetzHack - short topic
    • Artist: Radio ARA
    • Album: DD.MM.YYYY with guest1, guest2 guest3
    • Genre: Broadcast Show
    • etc...
  • Upload the file into the media section
  • Create the webpage as follows

Title: Lët’z Hack DD.M.YYYY – short topic

  • topic 1
    • explanations on topic 1
    with links to twitter profiles of participants and links to further infos
  • topic 2
