2012 OLF audio
This page is to coordinate activities for editing the audio files from the 2012 Ohio LinuxFest. It is divided into a section for each SD card, which contains a number of talks. To claim a particular talk or set of talks, download the raw audio file from the linked directory and then change the entry in the "Editor" column from "unclaimed" to your name/e-mail address. If it takes you more than a few days to work on them, e-mail Vance, otherwise he may revert it back to "unclaimed" so someone else can pick it up.
More specific instructions on editing will appear at the end of this page. When you're done, name the resulting WAV file as ##.wav with the track number from the table. Compress the WAV files as FLACs (this saves upload time and storage space) and upload them to INSERT LOCATION.

Editing Instructions
Some general notes:
- Audacity works fine, and is what I'll describe. If you like something else better, use that.
- Take care not to change the sample rate from the original. Some files are 44.1 kHz, some are 48 kHz. Using File -> Import in Audacity will cause resampling to the project's rate. Use File -> Open instead to avoid this.
- The final product will be a separate 1-channel (mono) 16-bit PCM WAV file for each talk. Compress this into a FLAC file before uploading to save time and space.
There are two methods that were used for recording the talks. The Early Penguin and Career Track talks were recorded using the H2's four built-in microphones. This results in two stereo files with the names SR###F.wav and SR###R.wav. The "F" comes from the front microphones and the "R" from the rear ones. The rest of the talks were taken directly from the PA soundboard via the line-in jack. These have only a single stereo file named STE-###.wav. All of these were compressed into .flac files before uploading.
Separating talks
Load the STE-###.flac or SR###F.flac file into Audacity with File -> Open. If applicable, also import the matching SR###R.flac file using File -> Import. Locate the beginning of the talk in question. There may be some random discussion, so find the place where the speaker "officially" starts their presentation. Highlight and delete everything prior to this point (Edit -> Delete). If you have more than one track on screen, make sure you hit all of them.
Next you locate the end of the talk. This is after the speaker has finished and any open question-and-answer period. Some recordings may capture post-talk conversations that individuals are having with the speaker. These should not be included as they are not intended to be public. Highlight everything from this point to the end of all tracks, and then delete.
Selecting audio channel
From the drop-down track menu (the downward-pointing triangle at the upper left of the track), select Split Stereo to Mono for each track. Now your job is to choose which of these sounds the best. You can isolate tracks using the Mute and Solo buttons on each track.
If you're working on a STE-###.flac file, there should really be no difference. If you find that one has more noise or lower signal, then delete that track by clicking the X in the upper left; otherwise, pick one at random to delete.
For the SR###F.flac / SR###R.flac files, you'll probably find that one of the channels is louder than the others. Pick whichever one seems to have the best signal to noise ratio, then delete the rest using the X in the upper left.
Normalizing
At this point you'll have just one single mono track left. Effect -> Compressor ADD DETAILS
Saving
Once you're happy with the way things sound, go to File -> Export. You can select "WAV signed 16 bit PCM" as the format, or if it's supported choose "FLAC" from within Audacity (make sure under "Options" you choose 16 bit). Name the file with the track number (e.g., 07.wav or 07.flac). WAV files can be compressed after the fact using the command line flac --best ##.wav which will create a file named ##.flac.
