Audio Loop Maker turns a single audio clip into a longer, repeatable loop in one simple step. Upload a file, choose how many times to repeat it, optionally add a small crossfade at the seam, and download a single MP3 output that plays continuously. This is useful for ambient beds, meditation backgrounds, game audio loops, short intros, and any sound that needs to run longer without manual editing. The backend uses FFmpeg concatenation to repeat your clip reliably across common input formats, and when crossfade is enabled it blends the end and start of repeats to reduce audible clicks. The tool reports estimated total input size, output size, percent size change, and final duration so you can confirm the loop length. An optional AI Assistant can suggest a practical repeat count and crossfade amount for your use case, but it only runs when you explicitly request it and it never changes your audio automatically.
Note: AI can make mistakes, so please double-check it.
Useful for ambient beds, intros, and game loops.
Free plan includes audio uploads up to 20MB. Paid plans unlock files up to 50MB.

Common questions about this tool
Upload your audio, set the repeat count, choose an optional crossfade amount, and click Make loop. The tool outputs one MP3 file that repeats your clip continuously.
Crossfade blends the end of one repeat into the start of the next repeat over a short window. This can reduce clicks and make the seam feel smoother, especially for ambient sounds.
This tool supports repeating a clip from 2× up to 20× in a single output. If your clip is very long, use fewer repeats to keep the final file size manageable.
The output is generated as an MP3 for consistent compatibility across browsers, devices, and editors. If you need WAV or another format, you can convert the MP3 afterward using an audio converter.
When you click Suggest loop settings with AI, the tool sends a small set of metadata (duration and use case) to a backend AI service. It returns a suggested repeat count and crossfade amount with a rationale, and you can apply them before running Make loop.
Upload your audio file, choose how many times to repeat it, set an optional crossfade, and click Make loop. The tool creates one continuous MP3 that repeats your clip in sequence.
Use a small crossfade at the seam so the end blends into the start. If the song has a strong downbeat or a hard ending, you may also need to trim to a better loop point before repeating.
Crossfade overlaps the end of one repeat with the beginning of the next repeat for a short time window. This reduces sudden waveform jumps that can sound like clicks and helps create a seamless audio loop.
It depends on how long you need the output to be. For background beds, 8–12 repeats is a common starting point; for sound effects, 2–6 repeats is usually enough to test or demo a loop.
The tool outputs MP3 for consistent playback compatibility across devices and editors. If you need WAV, AAC, or another format, you can convert the looped MP3 afterward using an audio converter.

An audio loop maker helps you turn one short clip into a longer track that repeats smoothly. This is useful when you have an ambient bed, a meditation background, a game soundscape, a short intro sting, or a sound effect that needs to play for longer. Instead of copying and pasting the same clip on a timeline, you upload your audio, choose how many repeats you want, optionally add a small crossfade at the seam, and download one continuous MP3.
Many people search for “make seamless audio loop” because they hear a click at the seam where the file restarts. A click usually happens when the waveform ends at a different amplitude than it begins. When the audio jumps from one value to another instantly, the discontinuity can sound like a transient click. A short crossfade helps because it overlaps the end of one repeat with the beginning of the next repeat and transitions between them gradually.
Crossfade is not magic: if your clip has a strong transient at the start (like a drum hit) or the end contains a tail that should not be overlapped, an aggressive crossfade can smear the sound. For those cases, a smaller crossfade (or no crossfade) may be better, or you may want to trim the clip before repeating.
People often arrive here looking for a seamless audio loop maker, a way to loop an MP3 file, or a quick way to repeat an audio clip for a specific use. Common searches include “audio loop maker online,” “repeat audio without gaps,” “loop music for meditation,” “make an ambient loop,” “create a game audio loop,” “crossfade audio loop,” “loop sound effect,” and “how to loop a song seamlessly.” This tool focuses on a practical workflow: upload once, set repeat count, optionally crossfade, download once.
A truly seamless loop is more than “repeat it.” If the end of your clip contains reverb tails or the start begins with a loud transient, the seam can still sound obvious even with crossfade. In those cases, the best improvement is often to trim the source so it begins and ends at a more compatible point, then apply repeating.
Crossfade length is a trade-off. Very short crossfades (like 50–120 ms) can reduce clicks while preserving sharp attacks, which is helpful for a loop sound effect. Medium crossfades (like 150–250 ms) can help smooth an ambient loop and reduce seam awareness. Longer crossfades can hide seams further, but they can also blur rhythmic timing and overlap elements that were meant to be separate.
If you are looking for an “audio loop maker for meditation,” you usually want longer playback and smoother seams, so a higher repeat count with a slightly longer crossfade is a good starting point. If you are looping a short sound effect, fewer repeats and a small crossfade often keeps the attack clean. If you are building a background bed for video, you might choose a moderate repeat count so the file is long enough for your edit without becoming huge.
| Use case | Repeat count (starting point) | Crossfade (starting point) |
|---|---|---|
| Ambient background | 8× to 12× | 150 to 250 ms |
| Meditation bed | 10× to 16× | 200 to 300 ms |
| Workout loop | 6× to 10× | 80 to 150 ms |
| Sound effect | 2× to 6× | 0 to 120 ms |
After processing, you receive a looped MP3 download and a quick summary. The tool shows an estimated total input size (based on repeating the source), the final output size, the percent size change, and the output duration. This makes it easy to sanity-check that your loop is the length you intended before you place it into a project.
If you need to loop background music for a 10-minute video, you can upload a 45-second bed and repeat it 12×, then use a small crossfade so the seam is less noticeable under narration. If you want to loop a song without a gap, you may trim the clip to a more compatible start and end, then apply repeating and a conservative crossfade to minimize artifacts.
Looping is often part of a larger workflow. These tools are commonly used alongside looping for trimming, joining, and smoothing edges:
