[edit] 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.

Best is to upload the show's FLAC via a big file mail service like http://filemail.com/

[edit] 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:

Effect->Normalize...
[x] Remove any DC offset
[x] Normalize maximum amplitude to
-[0.0]dB
[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

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

[edit] Importing

Following tools are needed: sudo apt-get install flac puddletag python-mutagen ffmpeg You may need: sudo add-apt-repository ppa:mc3man/trusty-media && apt-get update if ffmpeg is not found

if you got the flac from the original recording, convert it to mp3

InputFile="radioshow - date day.flac" # 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. beginning of 2016 it was 114

EpisodeTitle="" # title of the show, e.g. "Events Review" (write " as \")

Language=eng # eng=english

if original flac is used, this is not needed:

EpisodeDate= # date of broadcast, e.g. 20120414, can leave empty

Then run this code

EpisodeDate=${EpisodeDate:-$(mutagen-inspect "$InputFile"|awk '/Programme du/ {d=$(NF-1);gsub("-","",d);print d}')}

EpisodeYear=${EpisodeDate:0:4}

EpisodeMonth=${EpisodeDate:4:2}

EpisodeDay=${EpisodeDate:6:2}

MyName=${MyName:-$(id -un)}

FileName="LetzHack_ep${EpisodeNumber}_${EpisodeDate}_podcast.mp3"

TitleTag="Lët'z Hack! episode ${EpisodeNumber} - ${EpisodeTitle}"

ffmpeg -i "$InputFile" -qscale:a 0 "$FileName"

mid3v2 -a syn2cat -A 'LetzHack Radioshow' -t "$TitleTag" -c "::$Language" -y "$EpisodeYear-$EpisodeMonth-$EpisodeDay" "$FileName"

Go to the admin page of radio ara podcast server. If you have a password, you have the url (ok it's wordpress).
Upload the file into the media section
click on library and then on the just uploaded file: memorize the URL of the media file
Create the article as follows:
Link the file to the article in the "media URL" field
