Whatever kind of audio you're holding: a voice memo, a session export, something a client sent: flipping it to AAC gets you a file built for streaming-grade sound at friendly file sizes. Flippy reads practically any audio format and writes clean AAC, so you don't even need to know what the original is.

Why flip audio to AAC

Whatever the recording, audio just wants to be heard: the trick is picking a shape that plays where you need it. It was born in wherever your microphone, DAW or download came from, and its real weak spot is nothing in particular; the limits belong to whichever format it happens to be wearing.

AAC is MP3's better-trained successor: cleaner sound from the same number of bits. Advanced Audio Coding: the default soundtrack of YouTube, iTunes and most MP4 video. That makes it the right destination when what you need is streaming-grade sound at friendly file sizes.

Questions people ask

Will converting audio to AAC lose quality?

Flippy always picks the gentlest path: container swaps and extractions copy your streams untouched, and re-encodes happen once, at quality matched to the source.

Will the AAC file be bigger or smaller than my audio?

It depends on the format you pick as the output: lossy formats land a few megabytes per minute, lossless several times that.

Where will the AAC file play?

Apple everything, YouTube, Android, modern players; patchy on legacy gear. That's the usual reason people leave audio behind: AAC simply opens in more of the places that matter.

How long does audio to AAC conversion take?

Seconds for most files: audio is light work. A long recording might take a minute; your file auto-deletes from our servers within an hour either way.
