DD+、E-AC-3 、EC3三个说的是同一种格式

DD+、E-AC-3 、EC3三个说的是同一种格式,由于E-AC-3的音频文件后缀为.ec3,所以也有人成为EC3格式


Dolby Digital Plus 

E-AC-3 (Dolby Digital Plus) is an enhanced coding system based on the AC-3 codec.
 It offers increased bitrates (up to 6.144 Mbit/s), support for more audio channels (up to 13.1), and improved coding techniques 
(only at low data rates) to reduce compression artifacts, enabling lower data rates than those supported by AC-3 
(e.g. 5.1-channel audio at 256 kbit/s). It is not backward compatible with existing AC-3 hardware, though E-AC-3 codecs generally 
are capable of transcoding to AC-3 for equipment connected via S/PDIF. E-AC-3 decoders can also decode AC-3 bitstreams. 
The fourth generation Apple TV supports E-AC-3.[21] The discontinued HD DVD system directly supported E-AC-3. 
Blu-ray Disc offers E-AC-3 as an option to graft added channels onto an otherwise 5.1 AC-3 stream, 
as well as for delivery of secondary audio content (e.g. director's commentary) that is intended to be mixed with the primary 
audio soundtrack in the Blu-ray Disc player.

混音完成后,通过此插件可以输出Dolby Digital(杜比数字,ac3格式),以及Dolby Digital Plus(杜比数字+,ec3格式)。 也可以导入多声道的wav或aiff成品,直接输出5.1声道的ac3格式。

相关问题: ①由于该破解版插件目前尚处于内部测试版的状态,在Audition CC 2014中,无法调用该VST3插件及功能,不知是破解导致的问题还是软件自身的原因,总之原因不明。

②Premiere CC 2014版,本身也带了杜比数字和杜比数字+的编解码器,经多次实验,只能输出2.0,无法输出5.1。

准备工作

1、安装方法,参见《SurCode Dolby Digital 5.1 Encoder for adobe CC安装指南》

2、准备好5.1声道wav格式的音频素材,如果文件名很长,建议改短一些。

1、运行Audition CC 2014版,导入5.1 wav音频素材,本文拿做好的成品来示范;

2、按Ctrl+Shift+E,或“文件”->“导出”->“文件”,直接输出;

3、先输入文件名,再设定保存位置,然后,格式选,采样类型保持默认,按<确定>

注意: Audition CC 2014版,才有“杜比数字(*.ac3,*.ec3)”这个选项,2013版没有。
