Digital sound representation is key in computer science, involving the sampling, quantization, and encoding of sound. Bit depth affects audio quality by determining the dynamic range, with higher values ensuring more detailed sound. Various audio file formats, from lossless WAV and FLAC to lossy MP3 and AAC, cater to different needs for quality and storage. The balance between data rate and quality is crucial for optimal audio file creation and usage.

Analog sound waves are measured at regular intervals to create a series of discrete samples
Numerical values
Samples are assigned numerical values that represent their amplitude
Quantization is the process of assigning numerical values to samples
Quantized samples are encoded into a digital audio format for storage and playback
Bit depth determines the resolution of each audio sample
Bit depth directly impacts the dynamic range of digital audio
Higher bit depths can lead to higher quality audio reproduction
Lossless formats preserve the full quality of the original audio without any data loss
Lossy formats use data compression to reduce file size, but at the cost of some audio quality
Open-source formats provide a balance between audio quality and file size
Bitrate is a measure of how much data is transmitted or processed per second
Higher bitrates allow for more detailed and accurate sound reproduction
Lower bitrates result in more compact files and reduced resource usage
