# Audio Loop Concat Concatenate an audio file with itself multiple times to create a loop > Canonical page: https://elysiatools.com/en/tools/audio-loop-concat - **Category:** Media - **Keywords:** audio, loop, concat, repeat ## Overview The Audio Loop Concat tool allows you to easily repeat and concatenate an audio file with itself multiple times to create a continuous loop. Simply upload your audio file, select the number of repetitions, choose your preferred output format, and download the extended audio track. ## Inputs - **Audio File** (file): Select an audio file to loop - **Repeat Times (2-5)** (number): e.g., 4 - **Output Format** (select) ## When to use - When you need to extend a short background music track to fit the duration of a video. - When creating longer ambient soundscapes or white noise tracks from a short audio sample. - When preparing repeated audio assets for game development or presentation slides. ## How it works - Upload your source audio file using the file selector. - Choose the number of times you want to repeat the audio, from 2 to 5 times. - Select your desired output format from the available options, such as MP3, WAV, or FLAC. - Process the file to generate and download the concatenated looped audio. ## Use cases - Extending a 30-second instrumental beat into a 2-minute track for a podcast background. - Repeating a 1-minute rain sound effect 5 times to create a 5-minute relaxation track. - Looping a short sound effect for continuous playback testing in software development. ## Frequently asked questions ### What audio formats can I upload?
