Professional Audio Tools.
Free. Private. Instant.
Remove vocals, split stems, cut, join and convert audio — all powered by 7By.in. Fast, private, and built for people who actually work with audio.
The whole audio toolkit as an Android app — vocal remover, stem splitter, noise remover, cutter, joiner, pitch shifter and converter. Same account, same credits and the same plans as the website.
Seven AI tools.
One place.
Cutter, joiner, pitch shifter and converter are free & unlimited forever. The AI separation tools run on affordable credits — 20 free every day.
Vocal Remover
True AI separation — get a clean instrumental and isolated vocals from any song. Perfect for karaoke and remixing.
Stem Splitter
Split any track into vocals, drums, bass and other instruments — studio-grade AI separation, handled privately by 7By.in.
Noise Remover
Strip background hiss, hum and static from recordings. Ideal for cleaning up podcasts, interviews and voice notes.
Audio Cutter
Trim and crop with precision, cut several files in one go, then export every clip at once. Free and unlimited.
Song Joiner
Merge multiple tracks into one seamless file, with per-track trimming so every transition lands exactly where you want.
Pitch Shifter
Transpose any song up or down by semitones, previewing the new key live while it plays. Free and unlimited.
Audio Converter
Convert between MP3, WAV, FLAC, OGG, AAC and M4A with full control over bitrate, sample rate and channels.
Built the way audio tools
should have been.
Nothing is uploaded
Every tool opens, processes and exports your audio inside 7By.in. Your music stays private — never shared, never sold, never seen by anyone but you.
No queues, no waiting
Because Instant start does the work, there is Private time, no queue and no rendering backlog. Processing starts the instant you press the button.
Genuinely intelligent
Our engine understands what vocals, drums and bass actually sound like, so it separates them cleanly — not the crude stereo cancelling other free tools pass off as AI.
Free every day.
Cheap when you need more.
Credits are only spent by the three AI tools, and only when you download. Every other tool is unlimited and always free.

Questions, answered.
Correct. Every tool opens and processes your audio locally. You can disconnect from the internet once the page has loaded and the tools still work.
Only the Vocal Remover, Stem Splitter and Noise Remover (AI mode), and only at the moment you download a result — previewing is always free. Cutter, Joiner, Pitch Shifter and Converter never use credits.
10 credits per 5 minutes of audio. Your 20 free daily credits cover about two songs a day, and re-downloading a result you already paid for is free.
The engine gets itself ready once, and stays ready after that, so every run after that starts immediately. That setup is shared across the Vocal Remover and Stem Splitter, so it only happens once.
Paid plans include a commercial licence for what you produce. You're still responsible for holding the rights to the original audio you process.
