Sound is vibrating air.

Frequently the terminology of “individually necessary” and “jointly sufficient” is used. One might say, for example, “each of the members of the foregoing set is individually necessary and, taken all together, they are jointly sufficient for x’s being a square.”

Originally Answered: What are the necessary conditions for sound to be produced? You need two, maybe three things – something that’s vibrating, a medium for those vibrations to propagate in, and a listener to hear it (or recording equipment to pick it up).

Thus, three basic elements for transmission and reception of sound must be present before a sound can be produced. They are (1) the source (or transmitter), (2) a medium for carrying the sound (air, water, metal, etc.), and (3) the detector (or receiver).

(i) There must be a vibrating body which should be capable of transferring its energy to its surroundings. (ii) There must be a material medium to pick up energy and then propagate it in forward direction.

Sound is caused by the simple but rapid mechanical vibrations of various elastic bodies. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.

Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate.

Sounds may be generally characterized by pitch, loudness, and quality. Sound “quality” or “timbre” describes those characteristics of sound which allow the ear to distinguish sounds which have the same pitch and loudness. Timbre is then a general term for the distinguishable characteristics of a tone.

The highest quality MP3 has a bitrate of 320kbps, whereas a 24-bit/192kHz file has a data rate of 9216kbps. Music CDs are 1411kbps. The hi-res 24-bit/96kHz or 24-bit/192kHz files should, therefore, more closely replicate the sound quality the musicians and engineers were working with in the studio.

When it comes to audio bitrate size does matter. The more kilobits per second the greater the quality of the sound. For most general listening 320kbps is ideal. Of course, CD-quality audio that stretches to 1,411kbps will sound better.

The lower the Kbps, the more data the encoder will eliminate when compressing an audio file; the range for bit rates is from 96 to 320 Kbps. 128 Kbps quality is typically considered radio quality, and a bit rate of 160 or higher is equivalent to CD sound quality. To maximize sound quality, 320 Kbps is the best choice.

On most devices, Spotify defaults to a variable ‘Automatic’ setting and offers four fixed playback tiers: 24 kbps (Low), 96 kbps (Normal), 160 kbps (High), and 320 kbps (Very High).

WAV (Microsoft) 32-bit float No options for this format: 32-bit float WAV is a lossless format, a maximum quality “raw capture” file. 32-bit float resolution gives the highest quality of the three uncompressed choices, but takes twice the storage space on disk compared to 16-bit resolution.

FLAC is a compressed lossless audio stream, WAV is uncompressed lossless audio stream. FLAC is like ZIP in audio world, you can compress/uncompress the data multiple times without any loss. FLAC is superior to LPCM (WAV) in almost all aspects, but FLAC’s support is very limited.

Despite being an older format, the WAV file has several major advantages when it comes to professional, high fidelity recording applications. It is an accurate, lossless format – in a nutshell, this means that the format reproduced the recording accurately without losing audio quality due to the format itself.
