NiceVois

Every NiceVois audio tool. With no account: split_stems, split_lead_backing, remove_noise, remove_reverb and enhance_vocal (one free use of each per network, up to five minutes) and convert_format (free). With a connected account every tool runs on that account's plan (a subscriber's unlimited use applies), including generate_harmony (upper and lower harmonies from a solo lead vocal), which needs an account. Returns an upload URL; then use get_audio_job.

Split stems, isolate vocals, split lead from backing vocals, remove noise or reverb, or enhance a vocal. No account, API key or sign-up needed: one free use of each tool per network, of a file up to five minutes, as on the website. A connected account runs it on that account's plan instead. Returns an upload URL; PUT the file, then use get_free_audio_job.

Creates a private NiceVois job and returns a one-time PUT upload URL. Do not ask for consent before the first attempt because NiceVois remembers the current standing account agreement. If the server returns CONSENT_REQUIRED, ask for one acceptance of the linked standing agreement and retry once with acceptsStandingAgreement=true. This allocates a private training slot but does not start GPU work until the audio is uploaded and start_training is called.

Use this when the user has selected a private voice model and wants to convert one vocal recording. Returns a private upload instruction. Upload only the source vocal, then call get_voice_conversion with the same conversion ID. Creating it counts one of the account's conversions (three free per account, each up to five minutes long; it comes back if the conversion fails); listening and downloads are free.

Use this when the user wants to convert with an existing private RVC .pth file or complete model ZIP instead of a voice trained in their NiceVois library. Returns a one-time PUT upload instruction. After uploading, call list_voice_models to select the imported voice.

Use after get_voice_conversion says the job is complete and the user wants the cleaned or standard output. Downloads are free; the conversion was counted once when it started. If the exact file was downloaded before, ask before retrying and then set confirmRepeat true.

Returns a short-lived link to one output of a completed audio job. Download it or give it to the user straight away.

Use after create_audio_job and the upload, until the job is completed or failed. When complete it lists each output; call get_audio_download for the ones the user wants.

Use this when a user wants to convert vocals with RVC or compare a normal RVC result with NiceVois cleaned consonants and breaths. Returns the real input formats, model choices, workflow, current free-beta policy, and outputs.

Use this after create_free_audio_job and the upload, no more than every 10 seconds, until the job is completed or failed. When it completes, it lists every output file (for example lead vocal, backing vocals, instrumental) with a download link.

Call before quoting or creating a training job. Returns the connected account's welcome-credit status, available and reserved balance, balance packs, and a private browser link that keeps checkout on this same agent identity.

Use this to check truthful stage, completed epochs, ETA, and artifact readiness for one private NiceVois training job. Poll reasonably; do not call more often than every 15 seconds.

Use this before training an AI voice to confirm NiceVois input formats, duration and epoch limits, consent requirements, outputs, retention, and the exact upload workflow.

Use this when checking one private NiceVois conversion. Poll no more than once every 10 seconds. Report the returned stage without inventing progress. When complete, present the NiceVois cleaned version first and use download_voice_conversion_output for the version the user requests.

Use this to see NiceVois's free audio tools, which need no account, no API key and no sign-up: split a song into vocals and instrumental (vocal remover, acapella, karaoke instrumental), split lead vocals from backing vocals, remove background noise, remove reverb or echo, and enhance a phone-recorded or noisy vocal (Vocal Enhancer). Returns each tool's id, the accepted formats, and a website link to give the user when you cannot upload their file yourself.

Use this to find the authenticated user's recent NiceVois jobs before asking for a job ID they may not know.

Use this when the user wants to convert audio and you need to select one of their private NiceVois-trained or uploaded RVC voices. Do not ask for a model ID before calling this tool.

Call after inspecting the audio and before creating a job. Returns the exact payable amount, current balance, welcome-credit effect, shortfall, feasibility, and the private balance-page link when more balance is needed.

Use this only after the source audio was successfully PUT to the upload URL returned by create_training_job. Starts the private cloud RVC training job.
