Set (VBR) bitrate to <bitrate>. Note that while Opus allows for
decimal values, AtOM does not. The reason for this is simple: we do
numeric comparisons, and Bash only manipulates integers.

Prevent resampling (boolean):
LAME may decide to encode your file to a lower sampling-rate if you
use a low bitrate. Setting this to yes will append --resample
