Controlla
Controlla is a browser platform for voice swaps, voice cloning, and choirs, with 661 licensed voices, 30+ languages, and no claim on your masters. Free tier.
What is Controlla and how does it work?
Controlla is a browser platform built around one job: taking a vocal you recorded and turning it into something else. Another singer, an instrument, a different language, or a full choir. It runs entirely in a tab, with 661 licensed voices and a claimed 300,000 creators using it.
The thing separating it from the rest of the AI voice cloning category is breadth. Voice swap, voice cloning, stem splitting, song generation, lyric rewriting, and choir building all sit behind one subscription, so you are not paying 3 services to finish one track.
How it works:
- Upload a clean, dry vocal, one take with no reverb printed on it
- Pick a voice: your own cloned model, one of the 661 in the library, or a blend of 2
- Choose the tool you need (voice swap, Choir Studio, instrument conversion, or a lyric rewrite)
- Download the result as a 24-bit/48kHz stem with no baked-in compression, ready for your DAW
Recording quality sets the ceiling here, same as every voice tool I cover. Controlla’s own guidance is blunt about it: a soft room with carpets and curtains beats a hard reflective one, because room ring survives the conversion.
How much does Controlla cost?
Controlla runs a freemium model with 3 paid tiers. Yearly billing cuts 33% off every plan:
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | 600 credits total, 6 songs, 10 min of voice swaps, instant voice clone |
| Basic | $6/mo, or $4/mo yearly | 4,000 credits/mo, all tools, all royalty-free voices, no studio voice model |
| Plus | $12/mo, or $8/mo yearly | 10,000 credits/mo, 1 studio voice model per month, voice model sharing |
| Creator | $30/mo, or $20/mo yearly | 30,000 credits/mo, 3 studio voice models, all 600+ premium voices |
| Professional | Custom | API access, webhooks, volume pricing, fine-tuning, onboarding |
Credits are metered per second rather than per file, which changes the maths depending on the tool. Voice swap, stem splitting, and lyric swaps all cost 1 credit per second of audio. Song generation costs 200 credits and returns 2 songs. Song to MIDI, the Key and BPM Finder, and the Lyrics Transcriber are free on every plan, including the free tier.
Choir Studio is the one to watch, because it bills 1 credit per second per voice. A 30-second hook rendered at 16 voices costs 480 credits, so Basic’s 4,000 monthly credits buy you about 8 of those. At the full 32 voices the same hook costs 960 credits, and you get 4. Budget accordingly if the choir is the reason you subscribed.
Pricing changes frequently, verify current plans at Controlla pricing.
What can Controlla do besides voice swapping?
The tool list is the reason to pick Controlla over a single-purpose competitor. Voice swapping is the core, and 5 other things ship alongside it.
Instrument conversion. Hum a melody and get back a saxophone, a synth lead, a string section, or piano. No competitor in this price range does this, and it turns a producer who can hum into a producer who can write horn lines.
Choir Studio. Takes a single vocal and builds a full SATB arrangement of up to 32 voices. It needs a vocal from you, so it is not a text-to-choir button, though you can generate that vocal with Controlla’s own song generator first and feed it back in. Still marked BETA.
Voice cloning, 2 ways. The instant clone builds a model from a short sample on any plan. The studio clone trains on longer, better material for a closer match, and needs Plus or higher. Blend Voice mixes your voice with a library artist at whatever ratio you dial in.
Swap Lyrics. Drops new words into an existing recording while keeping the melody, timing, and delivery. Also BETA.
Stem splitting and utilities. A built-in splitter at 1 credit per second, plus Song to MIDI, key and BPM detection, and lyric transcription, all free. Those 3 alone replace a couple of browser tabs.
Every voice in the library is licensed and cleared for commercial release, and Controlla states plainly that it takes zero cut and makes zero claim on what you make. It also says your cloned voice stays private and is never used to train its models. That posture is stronger than most of the category, and it is worth reading against the label logos on the homepage, which are marketing placements rather than a published training-data licence.
How does Controlla compare to Kits AI and ACE Studio?
Each one is built around a different starting point.
| Controlla | Kits AI | |
|---|---|---|
| Starting price | Free, then $4/mo yearly | Free, then $10/mo |
| Core use case | Convert a recorded vocal into voices, instruments, or a choir | Vocal cloning and singing synthesis |
| Key differentiator | Instrument conversion and a 32-voice Choir Studio | Larger choir voice selection |
| Free tier | Yes, 600 credits | Yes |
| Best for | Producers who want one subscription for everything | Artists focused on voice models alone |
| Controlla | ACE Studio | |
|---|---|---|
| Starting price | Free, then $4/mo yearly | Free, then $16.58/mo |
| Core use case | Convert a vocal you recorded | Compose a vocal from MIDI and lyrics |
| Key differentiator | Speed, breadth, and price | Note-level editing of the performance |
| Free tier | Yes, 600 credits | Yes |
| Best for | Fast results without programming | Producers who write melodies in a piano roll |
Choose Kits AI when voice models are the whole job and you want the deepest library of them. Choose ACE Studio when you cannot sing the part and need to program it note by note. Choose Controlla when you already have a take and want the widest set of things to do with it for the lowest monthly cost.
Against I AM CHOIR specifically, Controlla wins on price, on platform (any browser, against macOS only), and on languages. It loses on privacy, since I AM CHOIR renders locally and Controlla uploads, and on ownership, since $199 once eventually beats a subscription you keep paying.
What are some use cases for Controlla?
- AI covers of your own songs: swap your recorded vocal into a licensed library voice and hear the track sung by someone else
- Reaching notes you do not have: sing the line in your comfortable range and convert it, one route I cover in the free AI voice cloning tools roundup
- Horn and string lines without players: hum the part and convert it to saxophone or strings
- A choir behind your chorus: run the hook through Choir Studio instead of booking singers
- Releasing in 30+ languages: sing once, ship the Spanish and Japanese versions from the same take
- Rewriting a lyric without re-recording: Swap Lyrics keeps the original delivery, useful for a clean radio edit
- Stem prep: pull a track apart with the built-in stem splitter before remixing
Controlla earns its place for artists who record their own vocals and want a lot of options on top, at a price where experimenting does not hurt. If you want a finished song written for you from a text prompt, Suno is the better lane.
Frequently Asked Questions
Is Controlla free?
There is a free tier with 600 credits, which covers 6 songs, 10 minutes of voice swaps, 10 minutes of stem splitting, and 6 Choir Sampler generations. Those 600 credits are a one-off rather than a monthly refill, so the free tier is a trial. Paid plans start at $4/mo billed yearly.
Can you use Controlla vocals commercially?
Yes. Every voice in the library is licensed and royalty-free for commercial release, including streaming, film, sync, and ads. Controlla states it takes no cut of your revenue and makes no claim on your masters.
Does Controlla train on your voice?
No. Controlla says a cloned voice is usable only by your own account and is never shared or used to train its models.
How does Controlla’s AI choir generator work?
Choir Studio takes one vocal you upload and builds an SATB arrangement of up to 32 separate voices. It bills 1 credit per second per voice, so voice count drives the cost as much as length does. The feature is still marked BETA.
Do you need to be able to sing to use Controlla?
For the best results, yes, since most tools convert a vocal you recorded. If you cannot sing, generate a vocal with Controlla’s own song generator first, then run that through voice swap or Choir Studio.
What languages does Controlla support?
More than 30, including Spanish, Japanese, French, German, Korean, Portuguese, Arabic, Hindi, and Mandarin. You can sing in English and release the same performance in a language you do not speak.
Does Controlla work offline or in a DAW?
No. Controlla is browser-based and processes in the cloud, so an internet connection is required. It exports 24-bit/48kHz stems with no baked-in processing, which drop straight into Ableton, Logic, or Pro Tools.
