Deze twee voordelen worden gebundeld in een kleine dongel. Met de WF100 kun je nu een robuust en snel draadloos netwerk opzetten dat muziek in CD kwaliteit streamt. De draadloze oplossingen van Audio Pro zijn te koop als een complete set, de WF-100 (1 zender, 1 ontvanger en 1 USB voeding) of los (de ontvanger, de RX-100 of de zender, de TX-100).
Audio Discution Forum. Audio formats. Hi-Fi. Bits is Bits? High-quality digital audio systems require that all digital interfaces in the signal path exhibit signal transparency. The widely adopted AES/EBU and S/PDIF interfaces have been criticized for a lack of signal transparency; here we (footnote 1) address possible problems with such interfaces and present methods for improving the interface standard. In a correctly functioning (uniformly quantized and sampled) digital audio system, the only observable signal impairments should be attributable to band-limitation and an additive noise residue. Thus, although digital audio's subjective sound quality has been criticized since the launch of the Compact Disc medium 13 years ago, the theoretical performance obtainable from the 16-bit linear PCM format sampled at 44.1kHz is superb to any analog sources available to the consumer.
When correctly dithered using triangular PDF dither, a 16-bit digital audio signal possesses a dynamic range of 93.3dB, with zero distortion and zero noise modulation.

Time For a Change? For decades, domestic audio systems have used SPDIF connections to carry digital audio from one box to another. This relies on a serial data format originally specified by Sony and Philips when CD Audio was launched. Each bit is sent one after the other in series. The format has some specific properties that make SPDIF vulnerable to various physical imperfections. For example, problems caused by the connection having a limited bandwidth or by being ‘mismatched’ in impedance terms. As a result it has become common to examine the ‘data induced jitter’ caused by imperfect transfer of SPDIF signals. This has used specific patterns of sample values and called the ‘J-Test’ – named after Julian Dunn of the AES who was a leader in investigating these problems. Timing ‘jitter’ can matter in practice because the receiving DAC may be affected and the result is an unwanted distortion that alters the analogue output. I recently started experimenting with a Halide Design USB-SPDIF Bridge.
S/pdif vs. Toslink? CD: Jitter, Errors & Magic. The promise of "perfect sound forever," successfully foisted on an unwitting public by the Compact Disc's promoters, at first seemed to put an end to the audiophile's inexorable need to tweak a playback system's front end at the point of information retrieval. Several factors contributed to the demise of tweaking during the period when CD players began replacing turntables as the primary front-end signal source.
First, the binary nature (ones and zeros) of digital audio would apparently preclude variations in playback sound quality due to imperfections in the recording medium. Second, if CD's sound was indeed "perfect," how could digital tweaking improve on perfection? Finally, CD players and discs presented an enigma to audiophiles accustomed to the more easily understood concept of a stylus wiggling in a phonograph groove.
Recently, however, there has been a veritable explosion of interest in all manner of CD tweaks, opening a digital Pandora's box. A Transport of Delight: CD Transport Jitter. Not that long ago, digital audio was considered perfect if all the bits could be stored and retrieved without data errors. If the data coming off the disc were the same as what went on the disc, how could there be a sound-quality difference with the same digital/analog converter? This "bits is bits" mentality scoffs at sonic differences between CD transports, digital interfaces, and CD tweaks. Because none of these products or devices affects the pattern of ones and zeros recovered from the disc, any differences must be purely in the listener's imagination.
After all, they argued, a copy of a computer program runs just as well as the original. As our knowledge of digital audio has become more sophisticated, however, we've learned that the timing of those ones and zeros is of utmost importance. It isn't enough to get the bits right; those bits have to be converted back into music with the same timing reference as when the music was first digitized.
There are two possible answers. Optical Discs, Deterioration and Future Storage. If you’re the owner of any albums on compact disc going back to their release in the early 1980s, you might have recently noticed that the tracks don’t play as well as they used to. Similarly, games and software that were purchased in the 1990s on CD-ROMs (or even some DVD-ROM titles from the past few years) might have become difficult to play, resulting in you scouring eBay for a replacement or trying to track down a reissue (if the game was particularly good).
DVD movie titles, too, seem to have suffered from aging – but what exactly is going on here? When first released, CDs and DVDs were said to be “indestructible” – save for scratches, the content on them should last forever. Yet over the past few years it has been shown that manufacturing faults and fungus have been able to destroy data, leaving CD- and DVD-ROM backups made by home users over the past 15 years potentially useless. So what can we do to get around this problem? Eaters of Data Optical Alternatives. Optische Toslink kabels | Knudde.be blog. Laatst had ik een optische S/PDIF kabel (Toslink) nodig voor mijn audio receiver, dus ging ik naar de winkel. Daar aangekomen viel ik bijna achterover van de prijzen: Bijna 25 Euro voor een metertje kabel! Tot 75 Euro voor een "High-end" uitvoering! Neen, dankuwel. (En dit was dan nog een winkel die adverteert de laagste prijzen te hebben.)
Ik heb uiteindelijk een optische Toslinkkabel van 1m voor 1,99 Euro gekocht, en dat werkt ook prima. Mijn overtuiging is: Koop de goedkoopste Toslink kabel die je kan vinden en hier is waarom: S/PDIF staat voor Sony/Philips Digital InterFace en is een digitale verbinding tussen verschillende componenten om audio over te dragen. De optische versie wordt "Toslink" genoemd en maakt gebruik van JEITA RC-5720 connectoren.
Nu zijn er helaas nog een heleboel andere optische kabels die gebruik maken van dergelijke JEITA RC-5720 connectoren, maar eigenlijk niet voor digital audio-overdracht bedoeld zijn. Voor alle andere mensen: Laat je niet afzetten! Internetmagazine en events rond beeld en geluid.
HDMI is Dead. Introducing HDBaseT Networking ? Reviews and News from Audioholics. HDMI is dead. How can we say this? Because we have seen the future and it is HDBaseT. HDBaseT technology runs over STANDARD Cat5e/6 cable and implements something it calls 5Play, an unrivaled feature-set that converges full uncompressed HD video, audio, 100BaseT Ethernet, and various control signals. Oh, it also transmits up to 100W of power - that's enough to drive a 37-inch TV. And it can extend up to 100 meters passively. HDBaseT has the bandwidth to support the highest video resolutions such as full HD 1080p as well as 3D and 2Kx4K formats. Think HDMI has a chance? We were fortunate enough tp speak first hand with Ariel Sobelman, President of the HDBaset Alliance. What makes HDBaseT so odd is that it is sending more info than HDMI over a set of 8 wires within a standard Cat5e or Cat6 cable. 5Play - Why You Should Be Impressed Sure, HDBaseT replaces HDMI with a standard Cat5e or Cat6 cable... but is that really impressive?
Power Over Cat5e/6? So What's Next? Well Cedia 2011 is here.
