How to make an M4R from a recording

  1. Prepare the opening

    Choose the audio or video containing the sound you want. The ringtone starts at the beginning of the file.

  2. Set the length

    Enter a duration from 5 to 40 seconds. If your source is shorter, the export ends with the source.

  3. Download the tone

    Select Export ringtone and save the AAC-encoded M4R. Transfer or import the file using your device’s ringtone workflow.

Give a short sound a clear beginning and end

Choose a recognisable opening and listen through the exit before putting the tone on a device.

Make a tone from a brand chime

Use an authorised recording of a shop or product chime for a team device.

Prepare an event cue

Turn the first few bars of a cue into a short file for rehearsal.

Use a recorded voice prompt

Start the source at the first word and finish before the next sentence begins.

Compare two ringtone lengths

Export two durations from the same opening and listen for the ending that feels most natural.

M4R ringtone maker FAQ

How long should my ringtone be?

Choose a length from 5 to 40 seconds. The export starts at the beginning of the file, so trim the recording first if the hook comes later.

Can I choose a start time?

The tone starts at zero. Trim your source to the desired starting point first if the useful sound begins later.

How does the ringtone end?

The export fades in for 0.6 seconds and applies a 1.2-second fade at the end of the selected duration.

Will downloading it set my phone’s ringtone?

The download gives you an M4R file. Importing it and assigning it to a contact or device are separate steps.

Which file format does the ringtone use?

The download is an M4R file containing AAC audio. Check that the device you plan to use accepts M4R.

What happens if my recording is shorter than the length I select?

The export stops at the end of the available recording. It does not repeat or pad the audio to reach the selected length.

Can I turn the middle of a song into a ringtone?

First trim the recording so it starts on the phrase you want. Use that excerpt as the ringtone source, then choose the length.
