2. Sound recording and reproduction - Wikipedia

   en.wikipedia.org/wiki/Sound_recording_and...

   Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording .

3. Digital audio - Wikipedia

   en.wikipedia.org/wiki/Digital_audio

   Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit resolution.

5. Comparison of analog and digital recording - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_analog_and...

   CDs became available in the early 1980s. At this time analog sound reproduction was a mature technology. There was a mixed critical response to early digital recordings released on CD. Compared to vinyl record, it was noticed that CD was far more revealing of the acoustics and ambient background noise of the recording environment. [37]

6. History of sound recording - Wikipedia

   en.wikipedia.org/wiki/History_of_sound_recording

   The second wave of sound recording history was ushered in by the introduction of Western Electric's integrated system of electrical microphones, electronic signal amplifiers and electromechanical recorders, which was adopted by major US record labels in 1925. Sound recording now became a hybrid process — sound could now be captured, amplified ...

7. Stereophonic sound - Wikipedia

   en.wikipedia.org/wiki/Stereophonic_sound

   Stereophonic sound attempts to create an illusion of location for various sound sources (voices, instruments, etc.) within the original recording. The recording engineer's goal is usually to create a stereo "image" with localization information.

8. Wave field synthesis - Wikipedia

   en.wikipedia.org/wiki/Wave_field_synthesis

   Wave field synthesis (WFS) is a spatial audio rendering technique, characterized by creation of virtual acoustic environments. It produces artificial wavefronts synthesized by a large number of individually driven loudspeakers from elementary waves. Such wavefronts seem to originate from a virtual starting point, the virtual sound source.

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.
