Of course, it's important to choose your equipment carefully and to understand what it is that makes HRA different.

HOW DO HD MOVIE AUDIO TRACKS DIFFER FROM THEIR ANALOGUE DOWNLOAD

Fueled by increasingly more affordable storage, better-quality playback hardware and faster, more affordable broadband and 4G downloading, HRA is arguably no longer prohibitively too expensive, nor are its files too large to download and store when compared with MP3.

There's also the fact that to listen to HRA you need the right hardware and software, with most playback devices including mobile phones, portable music players and laptops not equipped as standard to get the full benefit.Įven the world's most dominant multi-room music provider Sonos resolutely refuses to embrace Hi-Res Audio – because it says it's not mainstream enough – but others including the likes of Bose do.īut the barriers are starting to crumble.

The difference is that it’s becoming more accessible than ever.ĭespite sounding pretty amazing, it's not hard to understand the slow update of HRA – after all, the music files are a fair bit larger than MP3 or iTunes' AAC so they take longer to download and can gobble storage on mobile devices like penguins tucking into a fish supper.Ĭompared with iTunes and Amazon MP3 files too, HRA tracks are more expensive to buy and most popular digital music vendors don't even sell Hi-Res Audio tunes (yet). It has actually been around for over a decade and has a growing number of dedicated fans willing to fork out a bit more cash for the privilege of listening to Hi-Fi quality tunes both at home and on the go. Hi-Res Audio (HRA) is lossless audio capable of reproducing the full range of sound from recordings that have been mastered from better-than-CD quality music sources, a sound that closely replicates the quality that the musicians and engineers were working with in the studio at the time of recording.ĭespite HRA recently gaining popularity, it isn't new.

Here's why, and how, Hi-Res Audio could be the upgrade that makes perfect sense for superior sonics across all your devices, including your phone.

Several of the links on the next page go into this topic in detail, and also cover Dolby noise-reduction systems.įor more information on tape recorders, cassettes, magnetic recording and related topics, check out the links on the next page.As audiophile sound becomes more mainstream, Hi-Res Audio is looking like an increasingly attractive prospect. This movement means that the tape reproduces the sound recorded on it more faithfully. The bias moves the signal being recorded up into the "linear portion" of the tape's magnetization curve. A bias signal is a 100-kilohertz signal that is added to the audio signal. This works, but produces a lot of distortion on low-frequency sounds. The first tape recorders simply applied the raw audio signal to the electromagnet in the head. The controls on the tape deck let you match the recording bias and signal strength to the type of tape you are using so that you get the best sound possible.īias is a special signal that is applied during recording. Any tape player can play a metal tape, however. A normal tape deck cannot record onto a metal tape - the deck must have a setting for metal tapes in order to record onto them. Sound quality improves as you go from one type to the next, with metal tapes having the best sound quality. Metallic particles rather than metal-oxide particles are used in the tape. The ferric-oxide particles are mixed with chromium dioxide.

If you look inside a compact cassette, you will find that it is a fairly simple device. The cassette was patented in 1964 and eventually beat out 8-track tapes and reel-to-reel to become the dominant tape format in the audio industry.
