Frequently asked questions
What quality can I expect from WMA to M4R?
M4R is an Apple ringtone container that holds AAC audio, so the lossy WMA is re-encoded to AAC. Being lossy-to-lossy the result cannot exceed the WMA's quality, though for a short ringtone the difference is usually minor.
Why convert WMA to M4R?
M4R is the format iPhones use for ringtones, so converting lets a WMA clip be used as an iPhone ringtone rather than left in a Windows-only audio format.
Where does an M4R file work?
M4R is Apple's ringtone format, so it is intended for use as a ringtone on iPhones; as an AAC-based file its audio can also be read by players that support AAC.
What is lost in the conversion?
The original WMA stream is replaced by a re-encoded AAC track, and because ringtones are short the file is typically trimmed to a brief clip rather than the full audio.
