High-Definition Multimedia Interface (HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device. HDMI is a digital replacement for analog video standards.
Production of consumer HDMI products started in late 2003. In Europe, either DVI-HDCP or HDMI is included in the HD ready in-store labeling specification for TV sets for HDTV, formulated by EICTA with SES Astra in 2005. HDMI began to appear on consumer HDTVs in 2004 and camcorders and digital still cameras in 2006. As of January 2021[update], nearly 10 billion HDMI devices have been sold.
According to In-Stat, the number of HDMI devices sold was 5 million in 2004, 17.4 million in 2005, 63 million in 2006, and 143 million in 2007. HDMI has become the de facto standard for HDTVs, and according to In-Stat, around 90% of digital televisions in 2007 included HDMI. In-Stat has estimated that 229 million HDMI devices were sold in 2008. On April 8, 2008 there were over 850 consumer electronics and PC companies that had adopted the HDMI specification (HDMI adopters). On January 7, 2009, HDMI Licensing, LLC announced that HDMI had reached an installed base of over 600 million HDMI devices. In-Stat has estimated that 394 million HDMI devices would sell in 2009 and that all digital televisions by the end of 2009 would have at least one HDMI input.
The HDMI standard was not designed to pass closed caption data (for example, subtitles) to the television for decoding. As such, any closed caption stream must be decoded and included as an image in the video stream(s) prior to transmission over an HDMI cable to appear on the DTV. This limits the caption style (even for digital captions) to only that decoded at the source prior to HDMI transmission. This also prevents closed captions when transmission over HDMI is required for upconversion. For example, a DVD player that sends an upscaled 720p/1080i format via HDMI to an HDTV has no way to pass Closed Captioning data so that the HDTV can decode it, as there is no line 21 VBI in that format.
High-bandwidth Digital Content Protection (HDCP) is a newer form of digital rights management. Intel created the original technology to make sure that digital content followed the guidelines set by the Digital Content Protection group.
HDMI 1.3a was released on November 10, 2006, and had cable and sink modifications for HDMI Type C, source termination recommendations, and removed undershoot and maximum rise/fall time limits. It also changed CEC capacitance limits, and CEC commands for timer control were brought back in an altered form, with audio control commands added. It also added the optional ability to stream SACD in its bitstream DST format rather than uncompressed raw DSD.
Some cameras also have 4K capability,although cameras capable of HD video often include an HDMI interface for playback or even live preview, the image processor and the video processor of cameras usable for uncompressed video must be able to deliver the full image resolution at the specified frame rate in real time without any missing frames causing jitter. Therefore, usable uncompressed video out of HDMI is often called \"clean HDMI\".
HDMI can only be used with older analog-only devices (using connections such as SCART, VGA, RCA, etc.) by means of a digital-to-analog converter or AV receiver, as the interface does not carry any analog signals (unlike DVI, where devices with DVI-I ports accept or provide either digital or analog signals). Cables are available that contain the necessary electronics, but it is important to distinguish these active converter cables from passive HDMI to VGA cables (which are typically cheaper as they don't include any electronics). The passive cables are only useful if a user have a device that is generating or expecting HDMI signals on a VGA connector, or VGA signals on an HDMI connector; this is a non-standard feature, not implemented by most devices.
In addition to the features in common with HDMI (such as HDCP encrypted uncompressed high-definition video and eight-channel surround sound), MHL also adds the provision of power charging for the mobile device while in use, and also enables the TV remote to control it. Although support for these additional features requires connection to an MHL-enabled HDMI port, power charging can also be provided when using active MHL to HDMI adapters (connected to standard HDMI ports), provided there is a separate power connection to the adapter.
With impedance detection, adaptive voltage output, and a built-in digital-to-analog converter that supports sample rates of up to 96 kHz, you can enjoy high-fidelity, full-resolution audio directly from the headphone jack on your Mac.
The downloads themselves are available in a variety of formats. The most common format for downloads is FLAC. The open source nature of the format and the useful saving in space over a true uncompressed format starts to make a very big difference when you are dealing with albums that can be over a gigabyte in size. More recently, a number of sites have begun to offer downloads in the ALAC Apple Lossless format. This is useful for people using iTunes as their playback software.
This article assumes that you have an understanding of the common terms related to digital audio like frequency, sampling rate, and channels. If not, do check my article on the basics of digital audio here.
Just like digital video is made up of a series of still images played quickly enough that you see them as continuous, digital audio is comprised of many data points played back at an extremely fast rate. Each one of these audio snapshots is called a sample. Audio sampling rate (in Hertz - Hz) tells you how many samples per second are played, so the higher the number, the greater the resolution. CD-quality audio (typical for most standard music, games, movies) for example uses a sampling rate of 44.100 Hz, or 44.100 samples per second, whereas Hi-Res formats use 96.000 or higher, so more than double!
Amarra Luxe is one of a few Amarra-branded products from developer Sonic Studio. The app supports a host of file types, including DSD, MQA, and FLAC. The app features built-in real-time DSD to PCM conversion, meaning you can listen without the need for a fancy digital-to-analog converter. You also get integration with Tidal and Qobuz, letting you listen to streams from multiple services in one place.
Surprisingly, 12 bits is probably enough for a decent sounding music master and to cater to the dynamic range of most listening environments. However, digital audio transports more than just music, and examples like speech or environmental recordings for TV can make use of a wider dynamic range than most music does. Plus a little headroom for separation between loud and quiet never hurt anyone.
At its most basic, streaming sends a digital file from a server or computer in near real-time across the Internet to its destination. Before streaming became popular, the way to get a remote file into your computer, was by a progressive download. When the download was finished, you had the file. The bigger the file, the longer it took until you get it.

Usted, en el estudio de grabación de su casa, probablemente ha visto este término. En los sistemas de grabación digital, la frecuencia de muestreo define cuántas veces la señal analógica enviada por un micrófono o instrumento es muestreada por segundo. Cuanto mayor sea el número, más muestras de la señal analógica se recogen por segundo. Sin embargo, no siempre el número más alto significa la mejor opción. 153554b96e
