About Quick trim and Interactive Editor

How to use Interactive Editor

  1. Choose Interactive Editor to arrange your original audio, or use Edit in editor to carry your current settings across.
  2. Trim, split and move clips on the timeline. Select a clip to open its controls. Undo and Redo let you try changes.
  3. Listen, choose an output format under Export, then export and download your mix. Save a project to continue later.

Quick trim keeps its settings and results when you switch modes. Interactive Editor opens original audio; Edit in editor also carries the selected settings. Save a project to keep tracks editable. Export a recipe to reuse a composition in either workflow mode.

The editor supports 20 audio sources, 50 MB each, 150 MB total and 15 minutes per source, with a 30-minute composition. Quick trim retains its existing limits. The final editor mix uses a peak limiter; heavily boosted Trimmer cuts can sound different from Quick trim’s clipping.

Make a ringtone: what to know

A ringtone is just a short piece of audio in the right format. Add a song or recording above, choose where the ringtone should start and press Ringtone: the trimmer keeps 30 seconds and saves an M4R file, the format iPhones use for ringtones. For Android, choose MP3 instead. Everything happens in your browser, so your music is not uploaded anywhere.

Detailed guide

Try a thirty-second ringtone without using a song

Use the public 40-second practice WAV linked below the tool. Keep Quick trim, open Exact times and set Start to 5 seconds. Press Ringtone: it should select 5–35 seconds, leaving a 30-second selection. Use Play selection to check the tone pattern.

For a broadly playable test choose MP3 under Save as, click Trim audio and download it. To try the iPhone format, choose M4R instead and save a second copy; browser AAC encoding support and phone installation are separate requirements. A successful download does not mean the phone has installed the ringtone.

How to make a ringtone

Add one audio file: MP3, M4A, WAV, FLAC, Ogg or WebM, up to 50 MB and 15 minutes. Tap or drag on the waveform to find the part you want, then place the start handle where the ringtone should begin. Press Ringtone to select 30 seconds from there. Play selection to check it, add a short fade out under Fade edges if you like, then click Trim audio and download the file.

You can also drag both handles yourself. This tool limits M4R selections to 40 seconds or shorter; if the selection is longer while M4R is chosen, a warning appears before you save.

Adding the ringtone to an iPhone

Creating an M4R file here does not install it on the phone. Use a ringtone-transfer method supported by your current iOS and computer software, then check that the tone appears in the phone’s ringtone settings.

GarageBand on iPhone can import an MP3 or M4A audio file and share it as a ringtone of up to 30 seconds. Follow the Apple instructions linked below the tool. That installation limit is separate from this tool’s 40-second M4R export cap.

Adding the ringtone to an Android phone

Android phones accept MP3 ringtones. Choose MP3 under Save as, download the file and open it from your phone's settings under Sound, then Ringtone, and pick it from your files. On some phones you may need to move it into the Ringtones folder first with a file manager app.

Questions about making ringtones

How long can a ringtone be?
This tool limits M4R selections to 40 seconds; its Ringtone preset selects 30 seconds. A phone or installation app can impose other requirements. Use a short MP3 for an Android test.
What is an M4R file?
M4R is AAC audio in an MPEG-4 file with the .m4r extension, the format iPhones use for ringtones. It is the same kind of file as M4A with a different name.
Can I use any song?
Use music you own or have the right to use. Streaming-app downloads are protected and cannot be added here.
Is my music uploaded?
No. The trimmer runs in your browser and the file never leaves your device.
How it works

How to trim audio

  1. Add one MP3, WAV, M4A, FLAC, Ogg or WebM audio file.
  2. Drag across the waveform to select a section, then move its handles to refine it. Tap to place the playhead, or open Exact times to enter precise seconds. Play the selection and add a short fade if you want softer edges; the preview plays the fades too. To cut something out of the middle instead, choose Remove selection. Open Volume to make a quiet recording louder, even out its level or turn it down.
  3. Choose MP3, WAV, M4A or FLAC and click Trim audio. For an iPhone ringtone, press Ringtone to keep 30 seconds and save as M4R. Listen to the result, then download or send it to another audio tool.

How to cut WAV audio to an exact length

Keep a quote from an interview, shorten a voice recording or take a sound effect from a longer WAV. Quick trim keeps one range or removes one range from the middle; your original recording stays unchanged.

To keep seconds 10–30 of a recording, add your WAV, open Exact times, set Start to 10 and End to 30, then play the selection. Choose WAV, click Trim audio and download the 20-second result.

Try it with our 40-second sample WAV (1.28 MB): it contains quiet synthetic tones, no speech or music. Keeping seconds 10–30 should produce a 20-second clip. Leave fades off and Volume at Original to compare the cut on its own.

Example: keep 10–30 seconds, preview the selection, then export as WAV.

What WAV format will I download?

Quick trim writes a new 16-bit PCM WAV. It avoids another MP3 or AAC encode, but it is not a byte-for-byte cut: browser decoding may change the sample rate, and a 24-bit or float source becomes 16-bit on export. Keep your source for archival or mastering work.

Use Interactive Editor for multiple cuts, join WAV clips, or convert the finished WAV to MP3 when you need a smaller sharing file.

For iPhone installation, follow Apple’s GarageBand ringtone instructions: import an audio file and share it as a ringtone of up to 30 seconds. Creating an M4R here does not install it; this tool’s separate M4R export cap is 40 seconds.

Frequently asked questions

Useful details

8 answers
Are my files uploaded?

No. The file is read and processed in your browser. Encoder code may download from our site when a format is first used, but your audio is never sent.

Can I trim WAV without converting it to MP3?

Yes. Choose WAV before pressing Trim audio, then download the result. Quick trim exports 16-bit PCM WAV without an MP3 compression step. The browser may resample the recording, and higher-bit-depth sources become 16-bit, so the output is not a bit-for-bit copy. WAV cannot restore detail already lost in a compressed source.

How long can the WAV recording be?

Quick trim accepts one audio file up to 50 MB and 15 minutes. Very large recordings can need substantial device memory after decoding. If a WAV will not open, check both its file size and duration; its codec must also be supported by your browser.

Can I cut to an exact time?

Yes. Open Exact times to type start and end in seconds to two decimal places, or use the waveform handles and arrow keys. Play selection before exporting.

How do I make an iPhone ringtone?

Place the start where the ringtone should begin and press Ringtone: it selects up to 30 seconds and M4R. Toolkitta caps M4R exports at 40 seconds; a download does not install the tone. For GarageBand on iPhone, export MP3 or M4A and follow the linked Apple instructions, which use a 30-second limit. Android phones can use MP3.

Can I remove a part from the middle?

Yes. Select the part to take out, such as a cough, a mistake or an ad, and choose Remove selection. The rest is joined with a 12-millisecond crossfade so the cut does not click. Play the cut to hear a few seconds either side before saving.

Can I make the audio louder?

Yes. Open Volume and choose Even out to bring the saved part to about −16 LUFS, a comfortable level for voice and music, without letting peaks clip; or choose Custom to change it by up to 12 dB either way. A large boost can push peaks past full scale; they are limited and the result says so. The preview plays the original volume.

Does this change the original?

No. The original file remains untouched. Download the new clip after you preview it.
