2. Noise reduction - Wikipedia

   en.wikipedia.org/wiki/Noise_reduction

   Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio .

3. Audio feedback - Wikipedia

   en.wikipedia.org/wiki/Audio_feedback

   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 ). In this example, a signal received by the microphone is amplified and passed out ...

4. Active noise control - Wikipedia

   en.wikipedia.org/wiki/Active_noise_control

   Active noise control ( ANC ), also known as noise cancellation ( NC ), or active noise reduction ( ANR ), is a method for reducing unwanted sound by the addition of a second sound specifically designed to cancel the first. The concept was first developed in the late 1930s; later developmental work that began in the 1950s eventually resulted in ...

5. Delay (audio effect) - Wikipedia

   en.wikipedia.org/wiki/Delay_(audio_effect)

   Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo -like effect, whereby the original audio is heard followed by the delayed audio. The delayed signal may be played back multiple ...

6. Dynamic range compression - Wikipedia

   en.wikipedia.org/wiki/Dynamic_range_compression

   It is a form of upward compression that facilitates dynamic control without significant audible side effects so long as the ratio is relatively low and the compressor's sound is relatively neutral. On the other hand, a high compression ratio with significant audible artifacts can be chosen in one of the two parallel signal paths.

7. Background music - Wikipedia

   en.wikipedia.org/wiki/Background_music

   Background music is commonly played where there is no audience at all, such as empty hallways, restrooms and fitting rooms. It is also used in artificial space, such as music played while on hold during a telephone call, and virtual space, as in the ambient sounds or thematic music in video games. It is typically played at low volumes from ...

8. Robotic voice effects - Wikipedia

   en.wikipedia.org/wiki/Robotic_voice_effects

   Of the robot voice effects listed here, this one requires the least resources, since delay units are a staple of recording studios and sound editing software. As the effect deprives a voice of much of its musical qualities (and has few options for sound customization), the robotic delay is mostly used in TV/movie applications. References

9. Audio signal processing - Wikipedia

   en.wikipedia.org/wiki/Audio_signal_processing

   Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves — longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals or sound power level is ...
