Source format: TTA
TTA stands for True Audio, a lossless audio format designed to compress music without removing any sound data. It is used by audiophiles, archivists, and some audio software users who want exact preservation of the original recording while reducing file size. TTA files are typically found in music collections, backups of CD audio, and other situations where bit-perfect audio retention matters.
Target format: M4R
M4R is an AAC-based ringtone format used primarily by Apple devices, especially iPhone ringtones. It is essentially an M4A file with a different extension and is commonly used for short audio clips, alerts, and custom ringtones. Its advantages are broad compatibility with Apple ecosystems, small file size, and efficient compression for short audio segments.
How to perform the conversion
Because TTA is lossless and M4R is lossy AAC, the conversion is not a simple rename; the audio must be decoded and re-encoded. The best desktop tool for this task is FFmpeg, which can read TTA and create an M4R-compatible AAC file.
- Install FFmpeg on your computer.
- Open a terminal or command prompt in the folder containing the TTA file.
- Run a command like
ffmpeg -i input.tta -c:a aac -b:a 128k output.m4r. - If you need a ringtone-length clip, trim it first or during conversion, for example with
ffmpeg -i input.tta -t 30 -c:a aac -b:a 128k output.m4r. - Transfer the resulting
output.m4rto your iPhone or import it into your Apple ringtone workflow.
If you prefer a graphical workflow, you can also use audio editors or converters that support both formats, then export to AAC/M4R. On 101convert.com, you can convert the file online for free without installing any software.
Notes on quality and limitations
The main limitation is that TTA is lossless while M4R is compressed and lossy, so some audio quality is always discarded during conversion. For ringtones, this is usually acceptable, but it is not suitable if you want archival-quality preservation. Also, M4R is best kept short; Apple ringtone use typically expects clips of limited duration, so long songs may need trimming before conversion. Finally, compatibility depends on the target device: the file should be encoded as AAC in an M4R container for the best chance of working correctly on iPhone and iTunes/Finder-based workflows.
