"No, don't filter frequencies below 10 Hz with a loud mastered file. Despite some myths about Joint Stereo and Normal Stereo (especially on audiophile websites), Joint Stereo is almost always the best choice because it intelligently uses M/S to get the best quality out of the encoded bits. With dynamic material with at least a couple dBs of headroom you can turn on this option without worrying about overloads, though it will always impact the waveform in some way. This is mainly a problem with loud masters, having been subjected to a squaring of the waveform from brickwall limiting or intentional clipping. While it seems to make sense to filter out inaudible sub sonics this filter will change the relations between the frequencies which can cause more unnecessary overs during the lossy MP3 conversion as the waveshape integrity is further deformed. No, don't filter frequencies below 10 Hz with a loud mastered file. You can bounce to a real mono file by changing the Stereo Output channel strip in the mixer to mono (one circle) and clicking the bounce button directly on the output channel strip - not using the bounce menu option, which will always bounce to stereo regardless of the output channel strip setting. This means that the setting doesn't kick in with mono material in a stereo bounce, where the setting is instead completely ignored.
The mono bit rate setting isn't applicable unless you're actually bouncing to a single mono file on the disk. shoud Bit Rate Mono and Bit Rate Stereo be the same? Should I use "Best Encoding" and "Filter Frequencies below 10 hz"? Is Joint Stereo the best option or Normal?
