This one allows you to set metadata about the file. You can ignore
everything and just click "OK" to skip past this.
Congratulations! You've successfully converted a file to OGG Vorbis
format. You may now copy that file to the Micro SD card (don't forget to
rename it to a number!) for use with the Spectacle Audio Board.
Extra credit- trimming the fat and making the sound louder
As you can see in my file above, there's a great deal of room between the
extents of the sound and the extents of the window. In the time (horizontal)
axis, this manifests as flat lines before and after the content of the sound
file. In the "loudness" (vertical) axis, this manifests as space between the
top and bottom of the waveform file and the top and bottom of the playback
position window.
Let's eliminate some of that dead time before and after the sound plays. To
do so, simply click inside the playback position window and drag, as though
you are trying to select a section of text. The part you've selected will be
highlighted, as above. Now, just hit the "Delete" key on your keyboard, and
that section will be removed. Repeat the process at the other end of the
sound.
