Why use All Audio Tools?
Most online audio editors, including AI vocal removers, make you upload your file to a server, wait in a queue, and download the result, often with limits on file size or a watermark. All Audio Tools works differently. Each tool is built with the Web Audio API and runs inside your browser tab, so your recordings stay on your computer or phone from start to finish.
Private
Your audio is never sent to us or anyone else. That makes the tools safe for voice memos, interviews, unreleased music and client work.
Fast
There's no upload and no download of the original, so work starts as soon as you drop in a file. Big WAV files are just as quick.
Works everywhere
Use it on Windows, macOS, Linux, ChromeOS, Android or iPhone, in any modern browser like Chrome, Edge, Firefox or Safari.
Free
No account, no watermark, no daily limits. The site is supported by unobtrusive advertising.
What can you do with these tools?
Make karaoke and practice tracks. The AI-powered Vocal Remover uses the HTDemucs v4 model to separate the singer from the music, giving you a clean instrumental and an acapella. Musicians can use the Stem Splitter to separate a song into vocals, drums, bass and other instruments, and the Audio Scale Changer to move a song into a key that suits their voice or instrument.
Edit recordings. Use the Audio Cutter to cut a ringtone or clip from a longer track, or to remove a cough or mistake from the middle. The Audio Trimmer removes dead air from the start and end of a recording automatically, and the Audio Joiner merges several files into one with smooth crossfades.
Convert and shrink files. The MP3 Converter turns M4A, WAV, OGG, FLAC and even video files into MP3. WAV to MP3 and MP3 to WAV handle the two most common conversions in bulk, and the Audio Compressor makes files small enough for email and messaging apps.
Fix playback problems. Slow down a fast lecture or speed up a long podcast with the Audio Speed Changer, which keeps the voice sounding natural. Make a quiet recording louder without distortion using the Volume Booster.
Frequently asked questions
Are these audio tools really free?
Yes. Every tool on All Audio Tools is free to use with no account, no watermark and no limit on the number of files. The site is funded by advertising.
Do you upload or store my files?
No. Your audio is decoded and processed by your own browser on your own device. It is never uploaded to our servers, so we can't see, keep or share it.
Which audio formats are supported?
You can open any format your browser can play, which usually includes MP3, WAV, M4A/AAC, OGG, OPUS, FLAC and WebM, plus the audio track of MP4 and MOV videos. Results can be saved as MP3 or WAV.
Is there a file size limit?
There's no fixed limit. Because processing happens on your device, the practical limit depends on its memory. Files up to about an hour long work well on most computers, and phones are best with shorter files.
Do the tools work on phones and tablets?
Yes. The site works in modern mobile browsers on Android and iOS. Heavier tasks such as stem separation are faster on a computer.
