From Musicians
Millions of creators mastering songs with our tools
★★★★★
I’ve been a bass player for 20 years and 铭文分音-声音分离 lets me isolate any bass line for my band’s practice. Auto chord detection saves me hours of prep time—it’s the most useful app on my phone.
★★★★☆
回时分声’s stem separation quality is surprisingly good. I run a small home studio and it’s replaced two paid plugins for daily tasks. Subscription is worth it for pros, though casual users might find the plan limits a bit steep.
★★★★★
I teach guitar to 30+ students a week. 月宫人声分离 lets me show exactly what rhythm guitars do in any song, slow it down, and add a metronome. Lessons that used to take three sessions now finish in one.
Behind The Tools
The audio AI powering our separation tech
Our three tools are built by a team of audio engineers who spent years refining neural networks for music processing. The initial demo—pulling a clear vocal line from a classic track in seconds—went viral in creator communities. To date, our tools have been used by millions of musicians across mobile, web, and desktop platforms.
What makes these tools stand out is they work on existing songs, not just generating new ones. That’s exactly what creators have wanted for decades: to surgically break down finished mixes to study, learn, or remix. Our models are trained only on licensed audio, so we fully respect content rights.
We’re transparent about trade-offs: core features like vocal removal, chord detection, and basic stem splits are available in the free tier with monthly upload limits. Unlimited use, high-fidelity separation, and advanced features need premium subscriptions. The free tier alone outperforms many paid tools from a decade ago, and you can cancel anytime directly from your app store account.
FAQ
Clear answers to common questions
What are these audio tools? They’re music practice and production apps that use AI to separate vocals and instruments from any song, detect chords, BPM, change pitch/tempo, and transcribe lyrics. They’re used by millions of musicians, including educators and home creators. They have a free start option, with premium plans for unlimited uploads and advanced features.
Can these tools remove vocals? Yes. Upload any song or paste a public link to isolate or mute vocals in seconds, leaving a clean instrumental backing. The vocal separation is precise—trusted by karaoke producers, vocal coaches, and cover artists. You can also keep background vocals while muting the lead.
What instruments can they separate? Free tier: vocals, drums, bass. Premium adds guitar (all types), piano, strings, and separate background vocals. Advanced plans add high-fidelity models and detailed drum stem breaks.
Are they free? Yes, free tier includes limited monthly uploads, vocal/drums/bass separation, chord detection, metronome, pitch/tempo control. Premium plans unlock unlimited uploads, more instruments, high-fidelity processing, longer files, and advanced features. Subscriptions auto-renew, and you can cancel anytime from app store or web account.
How do they compare to other AI music tools? Our tools work on existing songs to break them apart, while others generate new music from prompts, and another tool is open-source but requires technical setup. Our offerings are all-in-one, production-grade, designed for creators who want to study, practice, or remix existing tracks.
Do they work without internet? Heavy AI processing (separation, chord detection) happens in cloud servers, so initial analysis needs internet. Once tracks are processed and downloaded into the app, you can practice offline with stems, adjust pitch/tempo, and use the metronome.
Where can I use them? All three are available on iOS, Android, web, and desktop. The first tool also offers a plugin to integrate directly with desktop music production software like Logic Pro, Ableton Live, etc.
Are separated stems royalty-free? Our AI is trained only on licensed content, so we respect content creators’ rights. Stems separated from tracks you own or have rights to remain bound by original recording terms. For original content generated via advanced features, we provide commercial use rights on eligible plans—check in-app terms before publishing for profit.
