Repeat by Count or Fit an Exact Duration
Choose complete plays when every repetition matters, or set the exact running time when the loop needs to fit another project.
Keep every repetition complete
Use total plays when each chorus, spoken phrase, bell or practice passage should finish before the next one begins.
- Choose between 2 and 20 total plays.
- See the estimated finished duration before rendering.
- Crossfade overlap is included in the duration calculation.

Fill the running time your project needs
Use target duration for a video bed, ambient track or timed session. The final play can be shortened so the result reaches the requested length.
- Enter minutes and seconds, up to 30 minutes.
- The tool calculates how many repetitions are needed.
- The final repeat may end early to meet the exact target.

How to Loop Audio Online
Go from one local file to a finished repeated track without copying and pasting clips on a timeline.
Upload one audio file
Choose a song, backing track, voice clip, ambience or sound effect from your device. Files can be up to 100 MB and 10 minutes.
Choose the part to repeat
Use the complete file, or drag A and B on the waveform to isolate a chorus, riff, spoken phrase or clean section of room tone.
Set the finished length
Choose 2–20 total plays, or enter the exact minutes and seconds required for your practice session, video or sound bed.
Preview the join and download
Compare the direct join with the optional crossfade, create the full result and download one file containing every repeat.
The same ending meets the start
Make the Loop Sound Smooth at Every Join
A hard cut can reveal a click or sudden change in level. Crossfade overlaps the tail with the next beginning so the transition has room to blend.
- Move A and B away from unwanted silence or sharp attacks
- Start with a short crossfade and listen to one join
- Compare direct and crossfaded previews in the real tool
Crossfade can soften the seam, but it does not detect beats, bars or a mathematically perfect loop point automatically.

What Are You Creating with Your Loop?
The settings change with the job: practice needs complete phrases, timed media needs an exact length and ambience needs a carefully checked seam.
Turn one difficult phrase into a complete practice track
Select the riff, solo or chorus with A and B, keep every play complete and export a file you can rehearse against without touching the player.
- 1
Listen once and place A before the phrase begins.
- 2
Place B after the final note or natural decay.
- 3
Choose a play count and check one join before export.

Make a short music bed fit the exact edit
Enter the running time of a video, voiceover or podcast segment. AudioMuse repeats the selected section and trims the final play to reach that target.
- 1
Select a steady section without a strong ending cadence.
- 2
Enter the required minutes and seconds.
- 3
Use a short crossfade, then finish fades in your editor if needed.

Extend room tone, nature sound or a steady texture
Choose a section whose beginning and ending have similar energy, then compare a direct join with a crossfade before building the longer sound bed.
- 1
Keep obvious impacts, voices and one-off events outside A and B.
- 2
Start with the direct join to hear the real seam.

Increase crossfade only until the transition becomes less noticeable.

A downloadable repeated file
An Audio Looper—not a Live Loop Station
AudioMuse takes audio you already have and writes the selected repeats into one new file. It is designed for preparing an asset, not overdubbing a live performance.
What stays the same
- Pitch, speed and the content of each selected play
- The original source file on your device
- Your chosen order: end followed by beginning
What it does not do
- Record or overdub microphone layers
- Detect bars, downbeats or ideal loop points
- Change BPM or transpose the recording
Need a live recording first? Use the Voice Recorder. Need to slow down or transpose a practice track? Open Audio Speed and Pitch Changer.
Create the Loop Without Giving Up Your Original
Processing happens on this device, the source stays unchanged and you choose the format of the new repeated copy.
Processed in your browser
Audio decoding, repeating, crossfade preview and export run locally. Your file is not uploaded for looping.
Five output formats
Choose a lossless editing copy or a smaller listening file. Re-encoding cannot restore detail missing from the source.
Your original stays unchanged
AudioMuse creates a new result and does not overwrite the recording selected from your device.

Audio Looper FAQs
Clear answers about A–B sections, play count, exact duration, crossfade, output formats and private browser processing.
How do I loop an audio file online?
Upload one audio file, keep the full recording or select an A–B section, then choose a total play count or an exact target duration. Add an optional crossfade, preview the join and create one downloadable file containing the repeats.
Can I loop just part of a song?
Yes. Drag the A and B handles on the waveform or enter precise start and end times. Only that selected section is repeated. Use full audio restores the complete recording without changing your original file.
Can I extend audio to an exact length?
Yes. Choose target duration and enter minutes and seconds, up to 30 minutes. The renderer accounts for crossfade overlaps and trims the final repeat at the exact target sample. Lossy formats or players may report a slightly different duration because of encoder padding.
Does three total plays mean three repeats after the original?
No. Three total plays means the selected audio plays three times altogether: the original play plus two additional copies. With no crossfade, a 10-second clip played three times produces 30 seconds.
How does crossfade make a loop smoother?
Crossfade overlaps the end of one play with the beginning of the next and blends their levels. It can soften a click or sudden level change, but it cannot automatically find musical downbeats or guarantee a seamless loop. Preview the direct and crossfaded joins before exporting.
Does the join preview match the exported crossfade?
The preview and export use the same decoded audio, selected region and linear crossfade calculation. The preview contains one short join rather than the complete output. Lossy MP3, M4A and OGG exports are encoded afterward, so they are not bit-for-bit identical to the WAV preview.
View all 11 questionsShow fewer questions
Will looping change the audio speed or pitch?
No. The tool repeats the selected recording without intentionally changing speed or pitch. Use Audio Speed and Pitch Changer when you need to change either property before creating the loop.
Is this a live loop station?
No. AudioMuse creates a downloadable repeated file from audio you already have. It does not record microphone layers, overdub a live performance or behave like a looper pedal.
Which audio formats can I use and download?
Upload a supported audio file or an MP4 containing audio. Download WAV, MP3, M4A, FLAC or OGG at 44.1 kHz stereo. WAV uses 16-bit PCM. Converting a lossy source to WAV or FLAC does not restore detail already lost.
How long can the finished loop be?
Choose 2–20 total plays or a target duration from 0.1 seconds to 30 minutes. Each source can be up to 100 MB and 10 minutes. The selected A–B region must be at least 0.05 seconds. Process one file at a time.
Is AudioMuse Audio Looper free and private?
Yes. The looper is free without an account. Audio is processed in your browser and is not uploaded for looping. Keep the tab open during processing and download the result before leaving.
