AUDIO TOOLKIT FOR MAC

Convert, trim, compress, merge, and edit audio without turning a simple task into a complicated project.

Designed for Apple silicon · Audio processing stays on your Mac

EVERYDAY AUDIO, CLEARLY ORGANIZED

Choose the task. Add your files. Export the result.

OmniAudio is a local audio toolkit for Apple silicon Macs. Each tool focuses on one familiar job and keeps optional technical choices out of the way.

Convert MP3, M4A, AAC, WAV, FLAC, ALAC, OGG, Opus, AIFF, or WMA, and save audio from video.

Keep one section, divide a long recording by time, count, or silence, and join clips in order.

Reduce file size, change speed or volume, and add smooth fades while keeping the task simple.

Export M4R or MP3 ringtones, and update cover art and tags in supported formats.

BUILT AROUND THE RESULT

File choices and output controls stay close to the task you are completing.

Compress one file or a whole batch while keeping the original format by default.

Preview and update cover art, title, artist, album, genre, year, and comments.
