The client software connects to a TeamSpeak server of the user's choice, from which the user may join chat channels. Users typically use headphones with a microphone; the target audience for TeamSpeak is gamers, who can use the software to communicate with other players on the same team of a multiplayer video game.
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).
However, the old mobile phones have a 2.5 mm jack connectors socket and cannot be used with modern microphone blockers that are typically 3.5 mm, but old mobile phones are notorious for their low security of the hardware itself. If a CTIA headset is connected to a mobile phone with OMTP interface, the external microphone will stay active.

The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio .
A lossless decoder then reproduces the original PCM with no change in quality. Lossless audio compression typically achieves a 30-50% reduction in file size. Common lossless audio codecs include FLAC, ALAC, Monkey's Audio and others. If additional compression is required, lossy audio compression such as MP3, Ogg Vorbis or AAC can be used.
The changing pressure deforms the granules, causing the contact area between each pair of adjacent granules to change, and this causes the electrical resistance of the mass of granules to change. The changes in resistance cause a corresponding change in the current flowing through the microphone, producing the electrical signal.
