A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ( streamed ) within the ...
The H2 Digital Handy Recorder H2 in use as a USB audio input device H2 and H4 with 10 eurocents for scale. The H2 Handy Recorder is a handheld digital audio recorder from Zoom first announced at the NAMM Show in February 2007. It records very high quality digital stereo or 4-channel audio on a hand-held unit, and has been called "the studio on ...
A similar approach to audio was taken with television landlines with two important additional complications. The first of these is that the television signal is a wide bandwidth covering many more octaves than an audio signal. A television equalizer consequently typically requires more filter sections than an audio equalizer.
Many electric guitar players intentionally overdrive their amplifiers (or insert a "fuzz box") to cause clipping in order to get a desired sound (see guitar distortion).. Some audiophiles believe that the clipping behavior of vacuum tubes with little or no negative feedback is superior to that of transistors, in that vacuum tubes clip more gradually than transistors (i.e. soft clipping, and ...
Audio over IP (AoIP) is the distribution of digital audio across an IP network such as the Internet. It is used increasingly to provide high-quality audio feeds over long distances. The application is also known as audio contribution over IP (ACIP) in reference to the programming contributions made by field reporters and remote events.
Presentation time stamps (PTS) are embedded in MPEG transport streams to precisely signal when each audio and video segment is to be presented and avoid AV-sync errors. . However, these timestamps are often added after the video undergoes frame synchronization, format conversion and preprocessing, and thus the lip sync errors created by these operations will not be corrected by the addition ...
The recorder section uses a full-size VHS transport fitted with a two-head VHS-C video head drum, and audio is carried on a mono 8 kHz linear track. Common problems are the brake band around the supply spindle coming off its plastic backing, and distortion of the microswitch which detects when the tape door is closed.
Block diagram of the signal-flow for a common feedback loop [1]: 118 . Audio feedback (also known as acoustic feedback, simply as feedback) is a positive feedback situation that may occur when an acoustic path exists between an audio output (for example, a loudspeaker) and its audio input (for example, a microphone or guitar pickup).
