Apart from regular quality improvements (tonality estimation introduced in 2.5.8.2 had been tweaked further-more, some ATH problems were fixed, better M/S allocation, new PNS algorithm, new bit rate/distortion control additional algorithms, etc..), AACEnc v2.5.9.7 (included in Nero 6.0.0.28) also has a brand-new algorihm for AAC encoding.
It is currently available under "fast" encoding mode, it is still very experimental and under development (however it is way better quality than old "fast" mode) - on very fast machines (P4) it won't be much faster, though  ))Anyway, this method has completely different quantization and coding kernel and some other changes, like bit allocation / bitres control - currently it is not yet fully finished, but it is capable of delivering very good results. |
