Change HandBrake from using the libsamplerate linear interpolator for resampling audio to using the SINC medium quality interpolator. Testing has shown a significant improvement in audio using this interpolator when upsampling the audio, most significant for 22Khz up to 48Khz, the audio is a lot brighter.
