Blu-ray authoring with truehd, how to do it?
TrueHD is a lossless audio codec that is used for high-definition audio on Blu-ray discs. It was developed by Dolby Laboratories and was first introduced in 2006 as part of the Blu-ray specification.
TrueHD is capable of delivering up to 24-bit audio at sampling rates of up to 192 kHz. This makes it capable of reproducing high-quality audio that is virtually indistinguishable from the original recording. TrueHD also supports up to 8 channels of audio, which makes it ideal for surround sound applications.
One of the key features of TrueHD is its ability to compress audio without losing any quality. This is achieved through the use of advanced compression algorithms that are specifically designed for audio. As a result, TrueHD can deliver high-quality audio at lower bitrates than other codecs, such as Dolby Digital.
Another important feature of TrueHD is its compatibility with existing Dolby Digital and DTS audio systems. This means that TrueHD audio tracks can be played back on older audio systems that do not support TrueHD, but will still sound better than standard Dolby Digital or DTS tracks.
In addition, TrueHD supports a number of advanced audio features, such as dynamic range control, which allows users to adjust the volume of dialogue and other audio elements without affecting the overall sound quality. TrueHD also supports Dolby Atmos, which is an object-based audio format that allows sound designers to place sound objects in a three-dimensional space for a more immersive audio experience.
Overall, TrueHD is a high-quality audio codec that is ideal for delivering high-definition audio on Blu-ray discs. Its lossless compression and support for advanced audio features make it an excellent choice for both home theater enthusiasts and audio professionals alike.
- High-quality audio: Dolby TrueHD is a lossless audio codec, which means that it can deliver audio that is virtually indistinguishable from the original recording. This makes it ideal for delivering high-quality audio on Blu-ray discs.
- Compatibility: Dolby TrueHD is compatible with a wide range of audio systems, including older Dolby Digital and DTS systems. This means that TrueHD audio tracks can be played back on a variety of audio systems, even if they do not support TrueHD.
- Advanced audio features: Dolby TrueHD supports a range of advanced audio features, including dynamic range control and Dolby Atmos object-based audio. These features allow for more precise control over audio elements and a more immersive audio experience.
- Lower bitrates: Despite its high-quality audio, Dolby TrueHD can deliver audio at lower bitrates than other codecs, such as Dolby Digital. This means that TrueHD audio tracks take up less space on a Blu-ray disc, allowing for more space for video content.
- Lossless compression: Dolby TrueHD uses advanced compression algorithms that allow for lossless compression of audio. This means that audio is compressed without losing any quality, resulting in high-quality audio that takes up less space.
While Dolby TrueHD audio has many benefits, including high-quality audio and compatibility with a wide range of audio systems, most Blu-ray authoring software on the market only supports AC3 encoding and not direct encoding of TrueHD.
