 // This test encodes an audio file using Opus twice with different bitrates
 // (12.5 kbps and 15.5 kbps). The runtime for each is measured, and the ratio
 // between the two is calculated and tracked. This test explicitly sets the
 // low_rate_complexity to 9. When running on desktop platforms, this is the same
 // as the regular complexity, and the expectation is that the resulting ratio
 // should be less than 100% (since the encoder runs faster at lower bitrates,
 // given a fixed complexity setting). On the other hand, when running on
 // mobiles, the regular complexity is 5, and we expect the resulting ratio to
 // be higher, since we have explicitly asked for a higher complexity setting at
 // the lower rate.
