However, the quality has been degraded compared to what could have been achievedīy native support for Dolby Digital Plus.
Once it was told that it was a Dolby Digital file by changing the extension, There’s diminishing returns but I’m guessing EAC3 at 2-3x the bitrate of AC3 is probably a sweet spot. I guess I should compare the two and see what I actually notice. EAC3 maxes out at like 10x the bitrate of AC3. This means that although the program you used does not support Dolby Digital Plus, I know AAC has better compression than AC3 so it’s possible EAC3 is bigger than it should be compared to TrueHD or Atmos. However, Dolby Digital Plus is a functional superset of Dolby Digital, and decoders include a mandatory component that directly converts (without decoding and re-encoding) the Dolby Digital Plus bitstream to a Dolby Digital bitstream (operating at 640 kbit/s) for carriage via legacy S/PDIF connections (including S/PDIF over HDMI) to external decoders (e.g. Dolby Digital developed AC3 that gives a surround sound experience. Relation to Dolby Digital and Dolby Atmosĭolby Digital Plus bitstreams are not directly backward compatible with legacy Dolby Digital decoders. AC3 is an audio file format that uses Audio Codec 3. The Wikipedia article for Dolby Digital Plus contains in the section 264 video with at least one AAC stereo track, and often AC3 5. To understand the following text, it is important to know that Dolby Digital surround sound is compressed which allows more audio information.
