2. 44,100 Hz - Wikipedia

   en.wikipedia.org/wiki/44,100_Hz

   In digital audio, 44,100 Hz (alternately represented as 44.1 kHz) is a common sampling frequency.Analog audio is often recorded by sampling it 44,100 times per second, and then these samples are used to reconstruct the audio signal when playing it back.

3. Comparison of analog and digital recording - Wikipedia

   The frequency response for a conventional LP player might be 20 Hz to 20 kHz, ±3 dB. The low-frequency response of vinyl records is restricted by rumble noise (described above), as well as the physical and electrical characteristics of the entire pickup arm and transducer assembly. The high-frequency response of vinyl depends on the cartridge.

4. Sound recording and reproduction - Wikipedia

   Frances Densmore and Blackfoot chief Mountain Chief working on a recording project of the Bureau of American Ethnology (1916).. 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.

5. History of sound recording - Wikipedia

   en.wikipedia.org/wiki/History_of_sound_recording

   The Western Electric system greatly improved the fidelity of sound recording, increasing the reproducible frequency range to a much wider band (between 60 Hz and 6000 Hz) and allowing a new class of professional – the audio engineer – to capture a fuller, richer, and more detailed and balanced sound on record, using multiple microphones ...

6. Wow and flutter measurement - Wikipedia

   en.wikipedia.org/wiki/Wow_and_flutter_measurement

   Measurement of wow and flutter is carried out on audio tape machines, cassette recorders and players, and other analog recording and reproduction devices with rotary components (e.g. movie projectors, turntables (vinyl recording), etc.) This measurement quantifies the amount of 'frequency wobble' (caused by speed fluctuations) present in ...

   The phonograph record was the primary medium used for music reproduction throughout the 20th century. ... Sensitivity and frequency range were poor, and frequency ...

8. High-resolution audio - Wikipedia

   en.wikipedia.org/wiki/High-resolution_audio

   Approximate dynamic range and bandwidths of some high-resolution audio formats. High-resolution audio is generally used to refer to music files that have a higher sampling frequency and/or bit depth than that of Compact Disc Digital Audio (CD-DA), which operates at 44.1 kHz/16-bit.

9. RIAA equalization - Wikipedia

   en.wikipedia.org/wiki/RIAA_equalization

   A recording is made with the low frequencies reduced and the high frequencies boosted, and on playback, the opposite occurs. The net result is a flat frequency response, but with attenuation of high-frequency noise such as hiss and clicks that arise from the recording medium. Reducing the low frequencies also limits the excursions the cutter ...
