# Audio Looper Create seamless loops from an audio clip > Canonical page: https://elysiatools.com/en/tools/audio-looper - **Category:** Media - **Keywords:** audio, loop, seamless, repeat, crossfade, music, production, rhythm, pattern ## Overview Extracts a segment from audio and creates a perfectly seamless loop with adjustable crossfade, repetition count, and tempo matching. Essential for music production, sound design, and creating rhythmic patterns that repeat without audible seams. ## Inputs - **Audio File** (file): Select an audio file - **Loop Start (seconds)** (number): Starting point for the loop segment within the audio file. - **Loop Length (0.1-30.0 seconds)** (range): Duration of each loop repetition. Shorter values = faster rhythmic patterns. - **Repetitions (1-100)** (range): Number of times the loop segment repeats. Higher values = longer loop sequences. - **Crossfade Time (0-2.0 seconds)** (range): Smooth transition between loop repetitions. Helps eliminate audible seams. - **Tempo Synchronization** (checkbox): Attempt to match loop length to musical tempo. May affect audio quality. - **Preserve Original Pitch** (checkbox): Maintain original pitch when adjusting tempo. When off, tempo changes affect pitch. - **Wet/Dry Mix (0-1.0)** (range): Balance between dry (original) and wet (looped) signal. - **Output Format** (select) ## When to use - When producing music tracks that require repetitive rhythmic patterns or beats. - For designing looping ambient sounds in games, videos, or interactive installations. - To create practice loops for musicians to improve timing and technique with consistent repetition. ## How it works - Upload an audio file in a supported format like MP3, WAV, or FLAC. - Set the loop start time and length to define the exact segment to be repeated. - Adjust the crossfade time to blend the end and start of each repetition seamlessly. - Specify the number of repetitions and optionally enable tempo synchronization for musical accuracy. ## Use cases - Creating drum and bass loops for electronic dance music production. - Generating background music loops for mobile apps, websites, or video content. - Producing sound effect loops for theater, film, or podcast post-production. ## Frequently asked questions ### What audio file formats are supported? The tool supports common formats including MP3, AAC, M4A, OGG, Opus, FLAC, and WAV. ### How can I make the loop sound seamless? Use the crossfade setting to smooth transitions between repetitions, eliminating audible clicks or seams. ### Can I change the tempo without affecting pitch? Yes, enable 'Preserve Original Pitch' to maintain pitch when using tempo synchronization. ### What is the maximum loop length per repetition? Loop length can be set from 0.1 to 30 seconds per repetition. ### How many times can I repeat the loop? You can choose to repeat the loop from 1 to 100 times. ## Related tools - [Audio Ambience Loop Generator](https://elysiatools.com/en/tools/audio-ambience-loop-generator): Extract the background ambience/room tone from a fragment and generate a seamless loop of any target length. - [Audio Loop Concat](https://elysiatools.com/en/tools/audio-loop-concat): Concatenate an audio file with itself multiple times to create a loop - [Language Learning Loop Maker](https://elysiatools.com/en/tools/audio-language-learning-loop-maker): Turn speech phrases into a repeatable practice track with a configurable pause between repetitions. - [Audio Spectrogram Generator](https://elysiatools.com/en/tools/audio-spectrogram-generator): Generate a spectrogram image from an audio file or a video audio track - [Audio Swing Feel Generator](https://elysiatools.com/en/tools/audio-swing-feel-generator): Apply long-short swing timing to transient-driven loops, with optional seeded humanization. - [Audio to Spectrogram Video](https://elysiatools.com/en/tools/audio-to-spectrogram-video): Create a video from audio with a spectrogram visualization - [Audio to Waveform Video](https://elysiatools.com/en/tools/audio-to-waveform-video): Create a video from audio with a waveform visualization - [Audio Waveform Generator](https://elysiatools.com/en/tools/audio-waveform-generator): Generate a waveform image from an audio file ## Samples - [Copyright-Free FLAC Audio Samples](https://elysiatools.com/en/samples/flac-samples): Lossless FLAC audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free MP3 Audio Samples](https://elysiatools.com/en/samples/mp3-samples): Collection of royalty-free audio samples for testing and development purposes including nature sounds, meditation music, and ambient audio - [Copyright-Free WAV Audio Samples](https://elysiatools.com/en/samples/wav-samples): Uncompressed PCM WAV audio samples for testing and development, mirrored from MP3 set with nature sounds and meditation music - [Copyright-Free Raw PCM Audio Samples](https://elysiatools.com/en/samples/pcm-samples): Raw PCM s16le audio samples featuring nature ambience and relaxing music for waveform, playback, and conversion workflows ## Related content - [Seamless Audio Loops, Ambience, and Rhythm Beds](https://elysiatools.com/en/hubs/seamless-audio-loops-ambience-and-rhythm-beds): Find clean loop seams, generate or extend ambience, align musical timing, and finish repeatable audio beds with fades, crossfades, and tempo-synced motion. - [Audio Pitch, Tempo, Looping, and Reverse Playback Tools](https://elysiatools.com/en/hubs/audio-pitch-tempo-remix-workflows): Shape pitch, tempo, speed, beat alignment, loops, reverse playback, and stutter patterns into a controlled audio remix workflow.
