Common name for a complete amplifying stage in any audio amplifier. Most amplifiers are denominated as 1, 2, 4, 5, or 6 channel units. Each of these is a discrete audio amp on its own, capable of taking a small line signal input and amplifying it sufficiently to be heard on an appropriate speaker. Some amplifiers are capable of bridging two channels together, to form one channel of double the power of each separately. The manufacturer's instructions differ widely on how to accomplish this, and each must be followed exactly.
An input module or section on a mixer that include input jacks and controls for adjusting the input signal.
An audio stream may consist of multiple interleaved channels. A mono stream has one channel, and a stereo stream has two channels. There is one sample per channel.
A stream of audio. Confusingly, a channel can refer to a mono audio bitstream or an interleaved stereo bitstream. (am I right here? -- Mark Rages)
A data stream of a given nature mapped over a connection is considered a channel. For example, a PCM data stream mapped over an RTP connection would be a single channel, even if that data stream interleaved more than 1 bearer in each packet. In like manner, any set of payload types that are all destined to the same HDLC endpoint would also be considered a channel.
A stream of sound intended to be reproduced through a single output device such as a loudspeaker. Monaural sound, for example, has a single channel that can't be split into additional channels.

popupid: audio_channel](Engine) A single stream of audio. Each stream can only play one sound at a time. The engine uses several channels for separate purposes, all of which are mixed together into a single stream (by either a software or hardware mixer) before being sent to the audio hardware device.

Defines the number of streams of audio. One channel is called mono and two channels (one right and one left are called stereo. During this workshop when recording your audio file, mono will be selected to reduce the file size and the amount of time it takes process (exercise 2). Stereo clips take twice as much time to download as a mono clip.
is the term we use to refer to types of media or interactions in the target language. Example are: newspapers, pop songs, blogs, TV, movies, podcasts, wikis, chat, IM, e-learning, streaming video, talking to a stranger in a bar--the list is long. Many language programs deliver limited results because the variety of channels is limited to teacher, coursebook, and audio. At English360 we help learners choose multiple channels based on professional needs, language level, learning style and personal interests.
An independently processed or recorded audio signal. Stereo has two channels, and Dolby Digital is five channels plus a subwoofer (DD 5.1)
