About Audio Compressor

About the Audio Compressor

The Audio Compressor shrinks an audio file's size by re-encoding it more efficiently — handy for email, faster uploads and lighter podcast feeds. You trade a little fidelity for a smaller file.

(For evening out loud and quiet levels, that is the Dynamic Range Compressor — this tool is about file size.)

Frequently Asked Questions

How much smaller will the file be?

It depends on the source and target bitrate — dropping a high-bitrate file to 128 kbps can cut size by more than half with little audible change for voice.

Does compressing lose quality?

Lossy compression discards some detail, but at sensible bitrates it's inaudible for spoken word. Keep your original as a master.
