M4A Fix

Voice memos from your iPhone won't play on your Android phone?

An iPhone voice memo can be ALAC (Apple Lossless) inside, even though the file

ends in .m4a like any other. Android can't decode ALAC, so it just says the

format isn't supported. M4A Fix converts those files to AAC, which Android plays.

■ Only the codec changes

Everything except the codec matches the original.

· Same sample rate, channels, and length

· Same bitrate as the original — not forced to a fixed 128 kbps

· Title, recording date, and other metadata are carried over

Your original is never touched. A new file named "name_aac.m4a" is created

beside it.

■ Everything happens on your device

Your recordings never leave your phone. Converting and playing are done

entirely on the device, with no internet connection required. Nothing is

uploaded anywhere.

■ See what needs fixing at a glance

The app lists the m4a files on your device by folder, showing each file's codec,

length, and sample rate. ALAC files — the ones that need fixing — are selected

for you, so one tap is enough. Convert several at once, and long recordings keep

converting even when the screen turns off.

■ Listen before you convert

ALAC files that Android can't play elsewhere play fine inside this app.

Grab the progress bar and drag to move to any point.

■ Clean up without leaving the app

After converting, the original and the new file sit side by side and take up

twice the space. You can delete the originals you no longer need right in the

app. Deletion goes through Android's own confirmation dialog, so nothing

disappears by accident.

■ Who this is for

· You switched from iPhone to Android and your voice memos won't open

· Someone sent you a recording from an iPhone that won't play

· You need to listen to call recordings, meeting notes, or lectures on Android

■ Good to know

· Files that are already AAC are left alone — there's nothing to fix.

· The app needs audio file access permission. It is used only to find the m4a

files to convert.

· There is one banner ad at the bottom of the screen. No full-screen ads that

interrupt what you're doing.
