+It was converted from MOD to WAV using Schism Tracker, in 16 Bit, Non-Interpolated mode, no output equalizer settings, Ramp volume at start of sample enabled.
+From there it was converted to OGG Vorbis with `ffmpeg -i flip-flap.wav -q 2.9 flip-flap-renc.ogg` (quality scale chosen to match size of the OGG file being replaced).
+Non-interpolated mode was chosen as the module has a high enough sample rate to balance it out, but seems muffled in other interpolation modes.
+If "Ramp volume at start of sample" is not enabled, a clicking phenomenon results.
