Please don't take this the wrong way, but I am curious why there is continued development of MP3 encoding (such as LAME) when AAC is now long-known to yield superior quality for a given bit-rate (all other things being equal)?
I can sort of understand an explanation as being for the heck of it, but given that a superior method exists, why not work on improving even that instead? I'm not technolgically sophisticated enough to comment with any authority at all, so I pose the question. |

While your AAC encoder is CBR (or "short windowed ABR") it can't compete with Apple and FhG AAC VBR encoders. As simple as it is. Period. P.S. Also I have a hard time to hear the difference between old Coding Technologies AAC encoder and your new Dolby Pulse encoder. For my ears it's just the very same encoder with some very tiny retouches. Rebranding the same product is a normal procedure today. This post has been edited by IgorC: Dec 20 2011, 14:24 |

Rebranding the same product is a normal procedure today. I am sorry if this is little bit out of topic. It's not my encoder it is Dolby's. There was an unofficial 48kbps HE AAC v1 listening test where Dolby Pulse was better than CT. There also was FhG and Nero but I cannot further discuss about the results as it is confidential information. According to Dolby; the Dolby Pulse is completely new encoder (not rebranded CT as you said). I guess the audio quality improvements are mostly hearable with HE AAC v1 and HE AAC v2. We would need a neutral ABX listening test for actual results. I guess the VBR improves the audio quality further when higher bitrate / AAC LC is used. I've discussed with Dolby R&D and I have a feeling there is a chance for VBR enabled Dolby Pulse. |
