In this episode, the HPR_AudioBookClub interviews David Collins-Rivera.
David's Voice work and Acting
As usual, the HPR_AudioBookClub took some time to review the beverages that each of us were drinking during the episode
- x1101: Green & Mint tea. Very mellow and refreshing
- Thaj: Typical homemade lemonade. Teeth rotting good :)
- pokey: I was drinking a can of Polar Lime Seltzer. I love seltzer, and lime is my favorite flavor. I think that seltzer feels (not tastes!) like cheap beer, and I once used it to help me quit drinking beer. I have since quit quitting beer, but I now I can't quit seltzer
Things We Talked About
OUR NEXT AUDIOBOOK
The Call of Cthulhu by H. P. Lovecraft
pegwole suggested this AudioBook, and we all thought that horror was a pretty good selection for our October episode.
Our next book club recording will be 2014/10/14T23:00:00+00:00. https://en.wikipedia.org/wiki/ISO_8601#Times If you'd like a Google calendar invite, or if you'd like to be on the HPR_AudioBookClub mailing list, please get in contact with us on the HPR mailing list 'hpr at hackerpublicradio dot org'
This episode was processed using Audacity http://audacity.sourceforge.net/. We've been making small adjustments to our audio mix each month in order to get the best possible sound. It's been especially challenging getting all of our voices relatively level, because everyone has their own unique setup. Mumble is great for bringing us all together, and for recording, but it's not good at making everyone's voice the same volume. We're pretty happy with the way this month's show turned out, so we'd like to share our editing process and settings with you and our future selves (who, of course, will have forgotten all this by then).
Mumble uses a sample rate of 48kHz, but HPR requires a sample rate of 44.1kHz so the first step in our audio process is to resample the file at 44.1kHz. Resampeling can take a long time if you don't have a powerful computer, and sometimes even if you do. If you record late at night, like we do, you may want to start the task before you go to bed, and save it first thing in the morning, so that the file is ready to go the next time you are.
Next we use the "Compressor" effect with the following settings:
- Threshold: -30db
- Noise Floor: -50db
- Ratio: 3:1
- Attack Time: 0.2sec
- Decay Time: 1.0 sec
- "Make-up Gain for 0db after compressing" and "compress based on peaks" were both left un-checked.
After compressing the audio we cut any pre-show and post-show chatter from the file and save them in a separate file for possible use as outtakes after the closing music.
At this point we listen back to the whole file and we work on the shownotes. This is when we can cut out anything that needs to be cut, and we can also make sure that we put any links in the shownotes that were talked about during the recording of the show. We finish the shownotes before exporting the .aup file to .FLAC so that we can paste a copy of the shownotes into the audio file's metadata. We use the "Truncate Silence" effect with it's default settings to minimize the silence between people speaking. When used with it's default (or at least reasonable) settings, Truncate Silence is extreemly effective and satisfying. It makes everyone sound smarter, it makes the file shorter without destroying actual content, and it makes a conversations sound as easy and fluid during playback as it was while it was recorded. It can be even more effective if you can train yourself to remain silent instead of saying "uuuuummmm." Just remember to ONLY pass the file through Truncate Silence ONCE. If you pass it through a second time, or if you set it too agressively your audio may sound sped up and choppy.
At this point we add new, empty audio tracks into which we paste the intro, outro and possibly outtakes, and we rename each track accordingly.
We adjust the Gain so that the VU meter in Audacity hovers around -12db while people are speaking, and we try to keep the peaks under -6db, and we adjust the Gain on each of the new tracks so that all volumes are similar, and more importantly comfortable. Once this is done we can "Mix and Render" all of our tracks into a single track for export to the .FLAC file which is uploaded to the HPR FTP server.
Remember to save often when using Audacity. We like to save after each of these steps. Audacity has a reputation for being "crashy" but if you remember save after every major transform, you will wonder how it ever got that reputation.
Thank you very much for listening to this episode of the HPR_AudioBookClub. We had a great time recording this show, and we hope you enjoyed it as well. We also hope you'll consider joining us next time. Please leave a few words in the episode's comment section.
As always; remember to visit the HPR contribution page HPR could really use your help right now.
