Choose the ringtone source

The source for your ringtone will most likely be an audio file on your computer. Select the file you want and import it into Audacity using the Project > Import Audio command. Audacity can import .MP3, .WAV, .AIFF, .OGG and .FLAC files. If your audio file is not in this format, you can convert it to .WAV or .AIFF (as long as it is not a purchased file) with SuperPlayer for Windows, FFMPEGX for OS X, or mplayer for Linux.

Alternatively you can play any audio file on your computer (including purchased files), or a CD, or any other sound on your computer including sounds playing over the internet, and record it. This is not the highest quality way to grab the sound from a CD or from a purchased file, but it is probably OK for making a ringtone, as quality often needs to be compromised in a ringtone to make the file size smaller. But if you want to grab a perfect digital copy of the CD track, or you cannot record it easily, extract it digitally to .WAV or .AIFF as described at How to import CDs. Or to make a perfect copy of a purchased file, burn it to an audio CD in the application licensed to play it, then extract the CD track in the same way.


Edit your ringtone

1) Click Project > Import Audio (or File > Import > Audio in Audacity 1.3.3) and import your source file. This can be any .MP3, .WAV, .AIFF, .OGG or .FLAC file that Audacity can open.

2) Select the portion of audio you want to use for your ringtone (say 15-20 seconds). To do this, click in the audio track and drag a selection area to left or right with your mouse - you can see the length of the selected audio in the timeline above the track. Many phones will loop the ringtone automatically (repeat it over and over), so choose your selection area with that in mind. To hear your selection play looped in Audacity, type L on the keyboard or hold down SHIFT while clicking the green Play button. To stop the playback, hit spacebar or click the yellow Stop button.

3) Click Edit > Trim. This will remove the rest of the file, leaving only the section you selected. If you want to use the whole file, then skip this step.

4) Add any effects you may want to the ringtone, by clicking in the Track Panel where the mute/solo buttons are to select all the track, then click the Effect menu. Be sparing with effects, but two you may want to consider are

- Equalization. Many phone speakers cannot reproduce very low frequencies so consider removing them. You'll notice a horizontal line that keeps a steady 0 dB across all frequencies. Using the mouse, you'll be able to click a series of points along the scale to create a curve. Bring the line down to -24 dB on the Y-axis for the low frequencies from 30-300Hz on the X-axis. You may want to increase the lower frequencies above this point say to 600 Hz, and reduce the highest frequencies above say 10 000 Hz. This should make the sound somewhat richer and less "tinny" on a small cellphone speaker.

- Compressor (which will reduce the difference between loud and soft and so make the ringtone sound louder). This will again suit a small cellphone speaker which may not be able to handle large changes in dynamic range. The terms of the compressor effect are as follows:

  • Threshold is the volume level at which compression starts to be applied. The further right the slider, the louder the input has to be before compression is applied.
  • Ratio - the further the slider is to right, the stronger is the compression applied
  • Attack time - amount of time compressor waits to respond after the Threshold is reached
  • If the "Normalize" box is checked then after compression the audio will be set to maximum possible amplification without adding distortion. This may be a bad idea on cellphone speakers which can give distortions before the maximum possible level is reached. Instead use Effect > Amplify after compression and choose a new Peak Amplitude (dB) of -3 dB.

Or instead of Compressor, consider using the Hard Limiter from the LAPSDA plug-in package which will also restrict the maximum volume to -3 dB. "Wet" and "dry" refer to the strength of an effect, with 1 being full effect and 0 representing no effect. Set the Hard Limiter to a dB limit of -3 dB, Wet Level to 1.0 and Residue Level to 0.0. Now, just the same as when you amplify to -3 dB after compression, you will get no signal above -3 dB, but you will also get a very sharp reduction in dynamic range which will be more extreme than that you get with the compressor.

If after Compressor or Hard Limiter your ringtone does not sound quite loud enough on the phone, you could try setting the Peak Amplitude or dB limit to -2 dB or -1 dB instead.


What type of file does your phone require?

You need to check what type of file format your phone requires for its ringtones, and whether the file needs to be mono or stereo.

Ringtone formats

There are many different ringtone formats in existence, but they fall into three main categories:

  • Monophonic - just one note at a time, usually RTTL format. If you want a ringtone in this format, it's often easiest to simply key it into your phone if it supports that.
  • Polyphonic - multiple notes at a time. Some phones can play true MIDI files, others rely on sp-midi or .mmf formats
  • Music ring tones - actual digitally sampled music files including .MP3 and .WAV supported by Audacity, plus other formats like .AMR and .QCP.

Most new phones will support polyphonic ringtones. Phones supporting music ringtones tend to be more expensive models, or PDA phones combining a handheld computer.


Convert stereo to mono

Irrespective of the required file format, many phones will want mono ringtone files. So if the track you are editing is stereo, the next step is to convert it to mono.

  1. Click on the name of the song (in the Track Panel to left of the waveform, where the downward pointing arrow is). This brings down a selection menu.
  2. Select the "Split Stereo Track" option.
  3. Click on the name of one of the resulting tracks then on "mono" using the same menu
  4. Close the other track by clicking on [X] on the Track Panel.

The remaining track will now only have the contents from one of the stereo channels you had before. If you want information from both channels in your ringtone, do this:

  1. "Split stereo track" as in step 1) above
  2. Click on the name of both tracks in turn and make each mono as in step 4)
  3. Select both tracks (CTRL + A ) and play them, and look at the green playback VU meter.

If the meter is not visible, enable it on the Interface tab of Preferences by checking "Enable Meter Toolbar". All you have to do is make sure the red lights to right of the green bars are not showing. If they are, you need to move the -....+ gain sliders (below the mute/solo buttons) on each Track Panel to left by the same amount until the green bars are well over to the right, but no longer bringing the red lights on. All this does is make sure you don't have distortion in the track. Then click Project > Quick Mix.

HINT: If you use Audacity 1.3.3, it's much simpler to convert stereo to mono! Instead of steps 2) to 5), just click in the Track Panel then Project > Stereo to Mono, which mixes in data from both channels to mono without distortion.


Export the file from Audacity

The following instructions show you how to export your edited (and mono if needs be) ringtone from Audacity as a .WAV or .MP3. If your phone needs a ringtone to be in some other format, skip to here.


Phones requiring .WAV files

If your phone requires an .MP3 file, skip to here.


As an example of exporting a .WAV file specific to a particular type of phone, consider the following Motorola Sprint Nextel cellphones:

i265, i275, i405, i450, i560, i710, 730, 750, 760, 830, i833, i836 ,850, 860, i870, i930

These require ringtones to be in the following format:

WAV (Microsoft); Bit depth: 8 bits; Sample Rate: 8 000Hz; Channels: 1 (mono)

If your phone has the same requirements as this, the instructions below should work for your phone. If the only information you have is that the .WAV needs to have a bit rate of 64 kbps, these instructions will also probably work for your phone, because in a .WAV file the bitrate is always the bit depth multiplied by the sample rate, multiplied by the number of channels, and so the .WAV in our example is (8 * 8 * 1) = 64 kbps.

If your phone requires .WAV files with slightly different characteristics than these, you can adjust the tutorial instructions below appropriately. It's assumed you've already made the file mono as per the instructions above.

  1. Look at the Project Rate button at the bottom left of the screen. If it is already showing "8000", skip to step 4) below. Otherwise, click on the button and select the "8000 Hz" option. If there isn't an 8000 Hz option, select "Other ..." and type 8000 in the box that pops up (or in 1.3.3, select and overtype one of the values).
  2. Click Project > Quick Mix.
  3. You'll see silence added to the end of the audio due to the conversion to 8 000 Hz, and silence in front if you chose a portion of audio that wasn't at the start of the track. Simply select the area of your audio again, and Edit > Trim. Note: If you use Audacity 1.3.3, it's much simpler: after changing the Project Rate button to 8000, do Tracks > Resample, type 8000 in the box that pops up, and click OK.
  4. In other than Audacity 1.3.3, click Edit > Preferences (Audacity > Preferences on a Mac) and then the File Formats tab. In the "Uncompressed Export Format" dropdown, select "WAV Microsoft 8-bit PCM)" and click OK. Then click on File > Export As WAV, select a file name to export your .WAV file to and hit Save.
  5. In In Audacity 1.3.3, click File > Export and in the "Save as type" dropdown in the Export File dialogue, choose "WAV, AIFF and other uncompressed types" and choose a file name to export to in the "File name" box above that. Click the Options button and in the "Format" dropdown, select "WAV (Microsoft 8-bit PCM)". Click OK, then Click Save.


Phones requiring .MP3 files

As an example of a phone requiring an .MP3 ringtone, the Motorola i580 requires MP3 files at

Bit Rate: 32 kbps; Sample Rate: 8 000 Hz; Channels: 1 (mono).

If your phone has the same requirements then it should also work for you. If your phone requires MP3 files with slightly different characteristics you can adjust the tutorial instructions below appropriately. It's assumed you've already made the file mono as per the instructions above.

  1. If you have not already done so, download the LAME MP3 encoder to your computer and tell Audacity where to find it. Instructions on doing this are here.
  2. Look at the Project Rate button at the bottom left of the screen. If it is already showing "8000", skip to step 3) below. Otherwise, click on the button and select the "8000 Hz" option. If there isn't an 8000 Hz option, select "Other ..." and type 8000 in the box that pops up (or in 1.3.3, select and overtype one of the values).
  3. In other than Audacity 1.3.3,click Edit > Preferences (Audacity > Preferences on a Mac) and then the File Formats tab. In the "MP3 Export Setup" section near the bottom, in the "Bit Rate" dropdown, select "32" and click OK. Then click on File > Export As .MP3, select a file name to export your .MP3 file to

and hit Save.

  1. In Audacity 1.3.3, click File > Export and in the "Save as type" dropdown in the Export File dialogue, choose "MP3 files" and choose a file name to export to in the "File name" box above that. Click the "Options" button, then at "Bit Rate Mode" select the "Constant" radio button, and choose 32 kbps in the Quality dropdown. Leave Channel Mode at "Stereo". Click OK, then click Save.


Phones requiring other formats

If your phone requires files in other than .WAV and .MP3 format, then the best course after editing the file is to export it as a 44 100 Hz 16 bit PCM .WAV file (either mono or stereo according to how the file is now), then convert it to the format you require with an appropriate conversion program.

  1. Look at the Project Rate button at the bottom left of the screen. If it is already showing "44100", skip to step 4) below. Otherwise, click on the button and select the "44100 Hz" option. If there isn't an 44100 Hz option, select "Other ..." and type 44100 in the box that pops up (or in 1.3.3, select and overtype one of the values).
  2. Click Project > Quick Mix.
  3. You'll see silence added to the end of the audio due to the conversion to 44 100 Hz, and silence in front if you chose a portion of audio that wasn't at the start of the track. Simply select the area of your audio again, and Edit > Trim as before. Note: If you use Audacity 1.3.3, it's much simpler: after changing the Project Rate button to 44100, do Tracks > Resample, type 44100 in the box that pops up, and click OK.
  4. Click Edit > Preferences (Audacity > Preferences on a Mac) and then the File Formats tab. In the "Uncompressed Export Format" dropdown, select "WAV (Microsoft 16 bit PCM)" and click OK.
  5. Click on File > Export As WAV and select a file name to export your .WAV file to.


Here is a selected list of programs to convert your exported .WAV to the format your phone requires:

SuperPlayer for Windows - WAV, MP3 and most formats to AMR, MMF (SMAF only)

FFMPEGX for OS X - WAV, MP3 and most formats to AMR

mplayer for Linux (command line tool) and Windows/OS X (interface versions) - WAV, MP3 and most formats to AMR

Mobile Ringtone Converter for Windows - WAV, MP3, OGG, AMR to AMR, MMF, WAV. Free conversion limited to maximum 4 seconds, and no more than 1/3rd of a file

Midi Music Polyphonic for Windows - WAV, MP3, MIDI to MMF

PV Converter for Windows - Converts WAV to QCP. There is a tutorial here. It is a command line program but can be simply used by dragging the file you want to convert onto pvconv.exe and the converted file is then created in the directory from which the original file was dragged.

WaveToMidi for Windows and Linux - WAV to MIDI (free with 25 second limit)

AudiotoMidi for Windows - WAV,MP3,CDA to MIDI

Midisoft for Windows and OS X - various MP3 and WAV to MIDI products


Uploading your ringtone to your phone

Once you have exported your file to the hard drive and converted it to another format if necessary, typically you would transfer the file to your cellphone in one of the following ways:

  • via a USB cable
  • via a wireless Bluetooth connection
  • via a Secure Digital (SD) Card Reader
  • upload it via the internet (e.g. to a web site, from which you can then download it to your phone). There is a free web service here that allows you to upload .MP3, .WAV, .M4A or .WMA files to their site. They then send a text message to your phone with a link to the ringtone, and you download it from the link using your phone's browser.

As another alternative, Mobile Ringtone Converter for Windows includes a Web and WAP (Wireless Application Protocol) server to which you connect with your phone's browser.

Note that some cellphones and carriers do not allow the user to download customised free ringtones to their telephone. See this page for guidance.

If in doubt, always look at the manual for your phone for advice on downloading ringtones.
