opus - Oct 2014 - low frequency content

Hello,

We are trying to figure out how to preserve the low-frequency content when
we try to convert a .wav file to an .opus file.  What settings in Opus that
can accomplish this?

Sincerely,

Vinson Go

If you care about low frequencies, use "audio" for the application
instead of "voip". You will have a high-pass cutoff of around 3 Hz
(compared to ~50 Hz for voip).
