MP3.mp3

MPEG-1 Audio Layer III is the most universally supported digital audio format in history. It uses lossy psychoacoustic compression to reduce file sizes tenfold.

WAV.wav

Waveform Audio File Format is IBM and Microsoft’s standard uncompressed audio format, storing linear pulse-code modulation (PCM) audio samples with complete fidelity.

FLAC.flac

Free Lossless Audio Codec compresses digital audio without discarding any sonic information, reducing studio-quality audio sizes by roughly 50%.

AAC.aac

Advanced Audio Coding is a lossy standard developed to succeed MP3, delivering noticeably superior sound quality at equivalent or lower bitrates.

M4A.m4a

MPEG-4 Audio is an audio-only container format commonly housing AAC or ALAC compressed sound. It is Apple’s standard audio container for iTunes and Voice Memos.

OGG.ogg

Ogg Vorbis is a patent-free open audio format designed to provide high-quality lossy audio streaming. Widely used in video game soundtracks and Spotify streaming.

OPUS.opus

Opus is an ultra-modern versatile audio codec standardized by the IETF. It excels at both interactive low-bitrate VoIP speech and pristine music streaming.

AIFF.aif

Audio Interchange File Format is Apple’s standard uncompressed audio format, functioning as the Macintosh equivalent of WAV with full PCM fidelity.

WMA.wma

Windows Media Audio is Microsoft’s proprietary audio format introduced in 1999 to rival MP3, once common across Windows PCs and portable players.

AMR.amr

Adaptive Multi-Rate is an audio compression format optimized for speech coding in 2G/3G mobile telecommunications and voicemail recordings.
