Fixing (hopefully) bandwidth detection for 24 kHz analysis The masking term was previously completely broken (even in 1.1). The bandwidth detection relies mostly on the noise floor and can only use masking to cut one extra band. The 12-24 kHz energy is now normalized properly but uses a higher noise floor due to the leakage in the resampler. Bandwidth detection is still mostly useless at identifying SWB speech (it usually says FB).
