Frequently asked questions
Will AIFF give me higher quality than the M4R?
AIFF is lossless and uncompressed, but converting a lossy M4R to AIFF only preserves the audio already present; it does not restore detail lost in the original AAC compression. The AIFF will sound the same as the M4R, just in an uncompressed form.
Why convert M4R to AIFF?
AIFF is a standard uncompressed format used widely in music production, so converting is useful when a clip needs to enter an editing or mastering workflow. It provides a full-quality PCM copy of the ringtone audio.
What opens an AIFF file?
AIFF opens in Apple Music, QuickTime Player, and VLC, and is supported by most professional audio editors.
Why is the AIFF so much larger?
AIFF stores uncompressed PCM audio, so it takes far more space than the compressed M4R. The larger size does not mean better sound than the source.
