like does a music file play a small "frame" of music that is strung together to make a sound or how does it work?


Answer:
The pieces are much smaller.

The standard sampling frequency for digital audio on a CD is 44.1khz (44,100 cycles per second) at 16 bit resolution.

Basically, what this means is that the analog to digital converters effectively take a picture of the audio waveform 44,100 times each second. The pieces are reassembled at the output by the D > A converter circuits.

Digital audio for video is sampled at 48khz, and at 96khz for HD DVD audio. The standard 16-bit word used for audio allows for 65,536 different "levels" per audio sample. Increasing it to 24-bit boosts that fidelity to 16.7 million, the same way that a higher bit rate allows more color gradations in graphics files.

High res 96khz - 24 bit audio files are finally able to approach the quality of audiophile analog sound.

peace

Answer:
Sound is synthesized according to volume and pitch.

Sound is a wavelength.
