AAC-LC tuned for 44.1/48 kHz? 2015-05-29 12:49:26 I've read that some MP3 encoders (e.g.: LAME) are more or less optimized for 44.1 kHz data. I'm a little less familiar with AAC format. I'm looking to encode a series of files in AAC-LC VBR (by way of qaac) and the input files are in 16/48. Would there be any advantage to downsampling this (I typically use SoX) to 44.1 kHz? Or does AAC-LC handle 48 kHz just as well as 44.1 kHz at the same bitrate?
