The Science of Sound: How Audio is Recorded and Reproduced
When I was 12, I remember asking my older brother "What is sound? And, how, from this random squiggle of lines, do you get the sound of an orchestra with a variety of instruments?" In essence, not only did I want to know what sound is but also how sound is recorded and reproduced. Unfortunately, I don't remember his explanation clearing things up.
Now, years later, with the help of one of our Friends of CircuitBread, PUI Audio, we are able to answer my 12 year old self. Using a series of examples and animations, we show what sound is physically, how it's a longitudinal wave that can be recorded as a transverse voltage wave, and how different sounds can be recreated with a single signal. We use some samples from PUI Audio to show how microphones record sound and how speakers can play th...

Sound recording and reproduction
Sound recording and reproduction is an electrical or mechanical 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. Acoustic analog recording is achieved by a small microphone diaphragm that can detect changes in atmospheric pressure and record them as a graphic representation of the sound waves on a medium such as a phonograph. In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it.

Unify Sound, Creation, Recording and Reproduction
The video discusses the challenge of unifying the various elements of instruments, sound reinforcement and playback to enhance engineering and sound system design. The speaker emphasizes the importance of understanding the complexities and nuances of sound capture and reproduction, including mic placement and the use of multiple perspectives. They explain the downsides of sending the same sound to multiple speakers, which creates comb filtering, interference, and summation issues. Techniques for capturing room sound during music recordings are also discussed, along with alternative approaches such as using close mic'ing and adding realistic-sounding reverbs in post-production. The speaker concludes with a demonstration of a Columbia graphophone from 1890 and talks about the mechanisms of h...

Sound recording and reproduction is an electrical or mechanical 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. Acoustic analog recording is achieved by a small microphone diaphragm that can detect changes in atmospheric pressure and record them as a graphic representation of the sound waves on a medium such as a phonograph. In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a bigger loudspeaker diaphragm causing changes to atmospheric pressure to form acoustic sound waves. Electronically generated sound waves may also be recorded directly from devices such as an electric guitar pickup or a synthesizer, without the use of acoustics in the recording process other than the need for musicians to hear how well they are playing during recording sessions.
Digital recording and reproduction converts the analog sound signal picked up by the microphone to a digital form by the process of digitization. This lets the audio data be stored and transmitted by a wider variety of media. Digital recording stores audio as a series of binary numbers representing samples of the amplitude of the audio signal at equal time intervals, at a sample rate high enough to convey all sounds capable of being heard. Digital recordings are considered higher quality than analog recordings not necessarily because they have higher fidelity, but because the digital format can prevent much loss of quality found in analog recording due to noise and electromagnetic interference in playback, and mechanical deterioration or damage to the storage medium. A digital audio signal must be reconverted to analog form during playback before it is applied to a loudspeaker or earphones.

The video discusses the challenge of unifying the various elements of instruments, sound reinforcement and playback to enhance engineering and sound system design. The speaker emphasizes the importance of understanding the complexities and nuances of sound capture and reproduction, including mic placement and the use of multiple perspectives. They explain the downsides of sending the same sound to multiple speakers, which creates comb filtering, interference, and summation issues. Techniques for capturing room sound during music recordings are also discussed, along with alternative approaches such as using close mic'ing and adding realistic-sounding reverbs in post-production. The speaker concludes with a demonstration of a Columbia graphophone from 1890 and talks about the mechanisms of horns as acoustic transformers. The video ends with a musical segment featuring the Death Fighter 2000 or DB.
