I'm currently rocking a 7.2.4 KEF R Series speaker configuration capable of reproducing DIRECT sound mixes like Dolby Atmos and DTS:X. Outside of compression issues and speaker variances, you're hearing exactly what the filmmakers want you to hear.

Rather, my intention is to give you a baseline of expectations when comparing the two technologies and how they perform in adding height sounds to traditional surround experiences, be they stereo, 5.1 or 7.1 sources.Īlso, my apologies for not including AURO 3D, which has also become available as a $150 firmware upgrade on some Denon AVRs, but my living room layout makes properly configuring AURO a bit of a headache, so I'm gonna have to sit that format out until further notice.įor the purposes of our discussion today, let's get really simplistic and say there are two types of sound experiences for the home cinema environment: DIRECT & UP-MIXEDĭIRECT experiences are simply when your AV Receiver DECODES a particular mix, be it stereo or 5.1 or Dolby Atmos. You can also compare Dolby Digital to other similar technologies like Dolby Digital Plus™.īlu-ray Disc data rate, 5.I was mid-review on the outstanding Denon AVR-X6200W 9-Channel AV Receiver when I came upon the topic of AVR sound processing, or up-mixing, and realized it might make a better standalone piece where we could talk about the sound processing outside the confides of a single product review.īefore we dive in, I want to make it very clear: Dolby and DTS fandom can run a little hot 'round the collar, but I'm not setting out to crown a winner here. As it needs only about one-tenth the bandwidth of each of the other channels, the LFE channel is referred to as a ".1" channel. The Low-Frequency Effects (LFE) channel delivers deep, powerful bass effects that can be felt as well as heard. The twin surround channels (Left Surround and Right Surround) create the sense of being in the middle of the action. The three front channels (Left, Center, and Right) provide crisp, clean dialogue and accurate placement of onscreen sounds.
The channels in a 5.1 audio mix serve distinct purposes. It ensures you enjoy a high-quality audio experience, whether you're listening on a mono, stereo, or 5.1-channel system, and also lets content creators offer additional features so you have more control over playback. Metadata is a set of instructions created during programming production and carried in the Dolby Digital bitstream. To ensure consistent playback regardless of your specific setup, Dolby Digital uses something called metadata. Once distributed, the compressed audio needs decoding.Īt the cinema, this decoding occurs in an audio processor, while in your home it can take place in a DVD player, a set-top box, a game console, or another familiar piece of equipment. The distribution of Dolby Digital audio can take many forms: a film print, a DVD, a television broadcast, a download.
This process is called encoding.īut rather than simply converting waveforms to numbers blindly, Dolby Digital analyzes the original audio and intelligently determines what parts of the audio track are important to keep and what parts you're less likely to hear.īy retaining the important parts of the audio track and eliminating redundant data, Dolby Digital delivers excellent multichannel sound at low data rates. Since the audio we hear consists of analog waveforms, not ones and zeroes, the first step in the process of creating a Dolby Digital audio track is to convert the original analog signal into digital information. Encoding and decodingĭolby Digital operates in a world of ones and zeroes - digital information.
This expands the creative palette for artists, and allows those of us in the audience to experience greater realism and excitement.

With Dolby Digital, it's possible to include a full 5.1-channel audio mix on a film print or a DVD, or as part of a TV broadcast. The smaller the file, the easier it is to distribute.

At its core, Dolby Digital technology represents a very efficient way for movie studios, television networks, and other content providers to compress the size of multichannel audio files without impairing the sound quality.
