Audacity is a free and open-source digital audio editor and recording application software, available for Windows, macOS, Linux, and other Unix-like operating systems. [4] [5] As of December 6, 2022, Audacity is the most popular download at FossHub, [8] with over 114.2 million downloads since March 2015.
For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint. First public release date is first of either specification publishing or source releasing, or in the case of closed-specification, closed-source codecs ...

Digital audio is a representation of sound recorded in, or converted into, digital form. In digital audio, the sound wave of the audio signal is typically encoded as numerical samples in a continuous sequence. For example, in CD audio, samples are taken 44,100 times per second, each with 16-bit resolution.
All WAV files, even those that use MP3 compression, use the .wav extension. This is a reference to compare the monophonic (not stereophonic ) audio quality and compression bitrates of audio coding formats available for WAV files including LPCM, ADPCM , Microsoft GSM 06.10 , CELP , SBC , Truespeech and MPEG Layer-3.

As the MP3 standard allows quite a bit of freedom with encoding algorithms, different encoders do feature quite different quality, even with identical bit rates. As an example, in a public listening test featuring two early MP3 encoders set at about 128 kbit/s, [75] one scored 3.66 on a 1–5 scale, while the other scored only 2.22. Quality is ...
An audio conversion app (also known as an audio converter) transcodes one audio file format into another; for example, from FLAC into MP3.It may allow selection of encoding parameters for each of the output file to optimize its quality and size.
