MP3 Audio Compression | Theory Notes & Revision
https://teachcomputerscience.com/mp3-audio-compression/
MP3 ranges from 96kbps to 320kbps. At the low end of the scale, 96kbps or 128kbps is comparable to FM radio, whereas at the high end of the scale, 256kbps to 320kbps is comparable to a CD. A CD transmits data at a rate of 176KB/s, or 1,400kbps. This means that a song recorded at the 96kbps bit rate is about 1/14 of the size of a CD track.

1.5:1 applies subtle compression. This ratio is gentle and transparent sounding. It will preserve the natural peaks and valleys. 2:1 applies light compression. This ratio smoothly controls the dynamics without causing noticeable changes to tone and punch. 3:1 applies moderate compression. This ratio setting is slightly more aggressive.
MP3 Compression: The Concept

The Algorithm MP3 Compression: The Concept Without any sort of compression, it would take 1.4 megabytes to represent just one second of CD quality music in WAV format, the de facto standard for sound on PCs. But by using MPEG audio coding, the size can be shrunk down by a factor of twelve without losing any of the sound quality.

First and foremost, MP3 is a lossy data compression technique by definition because we immediately drop the bit depth of the audio from 24 bit or above down to 16 bit. Lossy refers to this drop in resolution but doesn't have to mean a loss in audio quality. 16 bit is a depth that has plenty of headroom to provide a high signal-to-noise ratio. It means that every …

Answers (1) Jan on 14 Dec 2016 0 Link The compression ratio is the ratio between the size of tzhe compressed file or data and the uncompressed version. If you re-compress an MP3 file, it does not only concern the both file sizes. You have to define, if the header information (e.g. tags etc) of MP3 files is included or not.

Compression ratio specifies the amount of attenuation applied to the signal. You will find a wide range of ratios available depending on the type and manufacturer of the compressor you are using. A ratio of 1:1 (one to one) is the lowest and it represents “unity gain”, or in …

Generally speaking, 128 kbps (kilobits per second) is considered the bitrate at which an MP3 begins to exhibit artifacts of data compression. Not coincidently, it’s also the rate many websites use for downloads, since it offers a smaller file size with relatively minimal loss.
