Whatever kind of audio you're holding: a voice memo, a session export, something a client sent: flipping it to M4A gets you a file built for sounding great anywhere in the Apple ecosystem. Flippy reads practically any audio format and writes clean M4A, so you don't even need to know what the original is.

Why flip audio to M4A

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.

M4A is AAC in Apple's favorite outfit: the audio-only MP4 your iPhone speaks natively. An MP4 container holding only audio: usually AAC, occasionally Apple's lossless ALAC. That makes it the right destination when what you need is sounding great anywhere in the Apple ecosystem.

Questions people ask

Will converting audio to M4A 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 M4A 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 M4A file play?

iPhone, Mac and iTunes natively; most modern Android and Windows apps too. That's the usual reason people leave audio behind: M4A simply opens in more of the places that matter.

How long does audio to M4A 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.
