MP3

MPEG-1 Audio Layer III

MP3 is the most widespread audio format in the world. Lossy compression shrinks files to about a tenth of WAV, and it plays on every device.

WAV

Waveform Audio File Format

WAV usually stores audio with no compression at all (PCM). It is the lossless source for studio recording and editing, and its files are large.

M4A

MPEG-4 Audio

M4A is an MPEG-4 container that usually carries AAC audio. iPhone voice memos, iTunes music and many saved voice clips are M4A.

AAC

Advanced Audio Coding

AAC is the lossy audio codec developed as the successor to MP3. YouTube, Apple and streaming services use it; .aac files are a raw AAC stream.

OGG

Ogg Vorbis / Ogg Opus

OGG is the open container from Xiph.Org, usually carrying Vorbis or Opus audio. Telegram voice messages and many games use OGG.

OPUS

Opus Interactive Audio Codec

Opus is an open audio codec for speech and music with very low latency. WhatsApp voice notes are saved as .opus files.

FLAC

Free Lossless Audio Codec

FLAC is an open format that compresses audio to roughly half size without losing any quality. Music archivists and hi-fi listeners prefer it.

WMA

WMA is the audio format Microsoft built for Windows Media Player. It shows up often in old music libraries and songs ripped from CDs.
