Hi anarch0re
The intro song is loud, low bitrate sounding trumpet chiptune fanfare, which is
fine. The thing is, the shows are often recorded at a low volume level so the
volume must be adjusted upward to hear them... then after being soothed by a
soft spoken hacker voice, the blaring, loud chiptunes are blasted again at the
end of the show.
Fair point and you're not the only one that mentioned this.
We have several volunteers who will help us clean up the audio and help the
host improve their setup. We will on occasion farm the poor audio out to
auphonic.com to see if they can fix it.
However you don't mention which show in particular you are having a problem
with. Or do you feel that this is a problem with all of them ?
I have noticed for my shows that often the intro/outro is louder than my
recordings, both when I record using my phone or my computer. I have tried to
boost the audio levels to match the intro and outro. My audio editing skills
are still minimal, and often my audio would start to sound to harsh when I try
to amplify it too much. Until today, I didn't think about trying to download
the intro to use it help match the level.
I did download
https://hackerpublicradio.org/media/theme-music/intro-music-slick0-cc0-mono.flac. This
seems to be the standard intro clip used to attach to shows. One thing I did notice when
importing this clip into my Audacity project, the average volume db levels showing on the
meter fall between -12db and 0db, often being around -6db. When recording on my phone the
average levels are between -18db and -12db. Given how "hot" the recording
levels are for the intro clip along with type of audio it is -- it has a perceived
loudness much greater than a typical voice recording.
Perhaps a simple solution to the production process for the janitors, is to use
a clip that has its db levels decreased by -9db to -12db. This range seemed to
match the loudness of my default recording levels. Granted that would make the
situation much better for me ;) I have a Samsung Galaxy S9. I am sure the
recording levels vary to a degree from phone to phone, but maybe a quick survey
would give an average range to target.
If nothing else, having the intro/outro clips be a little lower than the users content
would solve the "sleepers" issue. They would turn it up (or not) to hear the
intro, then turn it down to the desired level while listening to the content. If they
fall asleep, the outro will be lower and not wake them up.
On another point, I did notice the "Loudness Normalization..." effect in
Audacity. I am going to try using that for my next show. After editing the main track(s)
of the show, I will then use this effect to try and bring the level up to the level of
the intro clip.
Cheers,
