![]() Qobuz is not alone in offering HD quality. But there is a good deal of coincidence involved. The narrower and more exotic the taste, the less chance. That is, sound with a larger resolution than the 16-bit/44.1 kHz which is the limitation of the CD format.ĭepending on your taste in music and luck, a larger or smaller part of the back catalog from your favorite artists will be available. But the next battshould will be HD audio. At least for listening on the home stereo. High resolutionĬD quality is a minimum requirement for hi-fi quality music enjoyment. And with Apple Music, the picture is the same. Spotify, which is largely dominant, delivers 320 kilobits as its “high quality” sound quality. Unfortunately, streaming has previously been associated with poor sound quality. And even if you have a well-grown music collection and enjoy the feeling of being able to hold an album in your hand, it is faster to find a specific piece of music with your mobile, than it is to kneel in front of the bookshelf and look. Streaming is fantastic: You have access to – more or less – all music, anywhere and anytime. The HD audio on Qobuz is streamed in the FLAC audio format, which is a packaged format but without data loss. Tidal streams losslessly in CD format on the HiFi service, while the high-definition music in the Masters service is streamed in the MQA format, which is loss-making but still supports HD audio. Spotify and Apple Music today both use the AAC file format, which is loss-making. And the lower the bit rate, the worse it sounds. That it is possible to throw away 90 percent of the signal and still have recognizable music is impressive.īut the deterioration is clear. A cunning algorithm discards the parts of the music signal that are allegedly inaudible because they are masked by louder sounds. So how do you push the extra data through the slow line? This is done by using lossy audio formats. And 24 bit/192 kHz HD audio costs 9.2 megabits per second if not compressed. CD quality requires a bit rate of 1411 kbit/s, ie approx. Spotify offers a bit rate of 160 kbit / s in the free version and 320 kbit / s in the paid version. The lower the bit rate, the less space there is for high definition sound. And all the while the human hearing at best reaches 20 kHz, the steep filters needed in the conversion can affect the sound further down in the frequency range.īit rate is an expression of how many bits per second the audio stream can transmit. Thus, 24 bit/44.1 kHz, 24 bit/96 kHz and 24 bit/192 kHz are all considered HD audio formats, but a higher sample rate will allow for a wider frequency range. definition anything that has higher resolution than CD. HD audio, ie high-resolution sound, is per. The sound on a CD has a resolution of 16 bit/44.1 kHz. The resolution indicates the “fine-grainedness” of the digital signal. Its high end is often brighter than Tidal’s, although on some hip-hop tracks Tidal’s low frequencies were a bit beefier.īoth services costs $20 per month, so it all comes down to personal preference.When it comes to streaming audio, there are three concepts to keep in mind: Resolution, bit rate, and whether the file format is loss-making. Specifically, whether listening to a song released this year or one released in 1980, Qobuz’s sound is bright and clear, with ample bottom and pristine definition. And in this writer’s opinion - based on an A/B with Tidal’s formidable Hifi service, through an expensive pair of Beats Studio headphones - the win goes to Qobuz by a nose, although allowances must be made for the type of music one is listening to. As we all know, music is an intensely personal experience, and sound quality is a big part of that (just ask any music head about their favorite headphones). It also offers playlists, exclusive editorial content and other standard streaming service amenities.īut whatever - anyone who’s read this far only cares about how it sounds. And while its catalog isn’t as complete as that of other streaming services, it offers up CD-quality audio of more than 40 million tracks, and millions of Hi-Res tracks up to 24-bit/192 kHz resolution from all genres. The company launched in 2009 as a hi-res download service, with its streaming option rolling out gradually over 20. “Our aspiration is to reach 1% of the market.” “We’re not competing with the big guys,” says U.S. already. While it doesn’t offer as deep a catalog as other streaming services, for many the sound quality may make up the difference. The company says it has almost 200,000 customers across the 12 markets in which it operates, with over 25,000 in the U.S.
