Understand between various audio file formats

 Understand between various audio file formats

Analog and digital sound

Analog waveform is continuous and has successice crest and troughs that represent highs and lows of your voice where as digital waveform is like barchart where highs and lows are represented by number

The quality for digital sound wave is linked to its sampling rate cd has a quality of 44100 samples per seconds (44.1khz) which is a quite good representation for our ears

Lossless vs lossy

These are two kinds of digital audio format

Lossless file is made without any losses relative to original track

In lossy format some some information that is unnecessary for listeners such as sounds that we cannot hear are discarded

Lossless format include wav, falc, aiff and apple lossless

Inside lossy format

Lossy formats other than the popular mp3 are wma aac mp2 and ogg. The difference between these format is the multiple encoding technology used

Other format has variable (vbr) or constant bitrates(cbr) . some format have variable bitrates, since they use higher bitrate for complex segments of the file and lower for the other segment

Vbr format have better quality to save space ration compare to cbr ones

Even inside each format there are different kind of bitrate for example mp3 usually found in vo ~245kbps v2 190 kbps and 320 kbps


Flac files are bigger than mp3 files. This is because of their bitrate

Bitrate is the amount of information processed per second whenever you play a file
