Loop Audio
「Loop Audio」는 이미지 및 디자인 작업을 위한 브라우저 도구입니다. 입력과 결과는 일반적으로 이 기기에서 처리되며 가입이 필요하지 않습니다.
LOCAL WAV EXPORT
Repeat audio for a set count or an exact duration
Choose a browser-supported audio file, set complete loops or a target length, then download a newly encoded 16-bit PCM WAV. Your source stays in this browser.
사용 방법
사용 방법
- Choose one browser-decodable audio file up to 50 MB and 10 minutes.
- Set a number of complete loops or an exact target duration, then check the uncompressed WAV size estimate.
- Create the 16-bit PCM WAV locally, preview it, and download the newly encoded file.
Two ways to set the result length
Complete-loop mode repeats every decoded source frame the requested number of times. Exact-duration mode writes only the requested number of output frames, so it can stop partway through the last repeat. The page shows the planned duration and an estimated WAV size before encoding.
A real, explicit output format
The tool decodes the selected file with the browser Web Audio API and writes a new RIFF/WAVE file containing 16-bit PCM samples. It does not rename the source or merely change its extension. WAV is broadly supported but uncompressed, so a WAV can be much larger than the original MP3, AAC, Ogg, or WebM file.
Limits and browser support
Input is limited to 50 MB and 10 minutes. Output is limited to 10 minutes and 100 MB; the actual limit can be lower for high sample rates or more channels because PCM WAV size is calculated before encoding. Browser audio decoding support differs by format and platform. The selected audio stays in this browser, and the export does not retain source metadata, cover art, compression, or container details.
자주 묻는 질문
더 알아보기
Can I make the final audio exactly 90 seconds?
Yes. Choose Exact target duration and enter 90. The last source repetition is trimmed at the exact requested output frame.
Why is the output much larger than my MP3?
The output is uncompressed 16-bit PCM WAV. MP3 and similar formats use compression, while PCM stores each audio sample directly. The size estimate is shown before encoding so you can choose a shorter duration if needed.
Which input files work?
The tool accepts common audio extensions, but the browser must be able to read metadata and decode the audio. Support varies by browser and operating system; a file that cannot be decoded shows a clear error instead of producing a renamed copy.
Does the tool upload or keep my audio?
No. Decoding, looping, previewing, and WAV creation happen in your browser. Refreshing or leaving the page discards the generated file URL.
