Yes. A clear MP3 can be uploaded directly and used to train an RVC .pth model. This is model training, not an instant file-format conversion: the MP3 is decoded and prepared as training data before the cloud GPU begins learning the voice.
You do not have to convert the MP3 to WAV yourself just to satisfy the uploader. Converting a lossy MP3 into WAV also cannot restore audio information that compression already removed.

Before you pay
Do I need an account to pay?
No. Pay with any email. Sign in with that same email on any device and everything you paid for is there.
What does unlimited actually mean?
No minutes to count on any tool, every output included, up to 500 epochs per training run. Fair use applies.
How do I cancel?
One click from your account, no email needed. You keep everything until the end of the month you paid for.
What if a training fails?
You are not charged for it. A failed or cancelled run releases what it reserved, and an upload that never arrives does not spend your free run.
Who sees my card?
Lemon Squeezy, the merchant of record. NiceVois never sees card details, and tax is handled at checkout.
Do I keep my voices if I leave?
Yes. Every model is a .pth, .index and ZIP you download, and they work anywhere RVC runs.
What happens to my audio?
It is processed for your job and never shared. Source audio is removed after validation. Models trained on a paid run stay until you delete them; a model from the free run is kept for 7 days, and its expiry date is shown on the model itself.
Can I hear it before I pay?
Yes. Your first training is free, and every finished model comes with a listening proof before you decide anything.
Wrong charge or an unused month? Email info@nicevois.com with the checkout email and date; it is reviewed with Lemon Squeezy and returned to the original payment method. Refund policy · Privacy

Persistent cloud storage
Your model library
Your voice models are files you own. Download them once and no platform can take them away.

Paid model packages stay saved until you delete them.
Your .pth, .index, ZIP, and private listening preview remain available after closing the browser or restarting your computer. A model from the free training run is kept for 7 days and shows its expiry date; download it before then. Full-resolution source audio and temporary training files are removed after validation.

When an MP3 is good enough
An MP3 can work well when the voice is clear, the bitrate is reasonable, and there is little background sound. Listen for watery high frequencies, ringing, swishy consonants, clipping, or heavy music bleed. Those problems are part of the training signal and may be repeated by the model.
Prefer the original MP3 over a copy that has been repeatedly exported.
Use one target speaker and remove sections containing other voices.
Do not increase the sample rate or bitrate and expect lost detail to return.
If you have the original WAV or FLAC, use that instead of the compressed derivative.
What the service does with the MP3
The official RVC training workflow reads supported source audio through FFmpeg, converts it into the representation required by preprocessing, and then extracts the features used for training. NiceVois runs that workflow in a pinned cloud environment and validates the exported model before showing the downloads.

What you receive
The finished model is available as a named .pth, a matching .index, and a ZIP containing both. The public workspace retains the completed files for the displayed seven-day window, and you can delete an inactive job from your private model library at any time.
