Audimee vs NEUTRINO

Audimee is a voice-to-voice platform for transforming vocals with built-in or custom voice models. Users can adjust melody with the Pitch Editor before conversion, isolate lead vocals from instrumentals and background vocals, and remove reverb, echo, and noise. Its harmony feature can turn one recording into up to five tracks with different voices and harmony lines. Users can train custom voice models with 1–30 minutes of vocal data, combine up to four models with Mixed Voices, and split tracks into two or four layers of vocals, drums, bass, and other sounds. The catalogue contains over 100 voices, with new additions released weekly. Audimee is cloud-based and accessible through a browser and/or desktop app. The Free plan is free and includes 15 minutes of conversions, 11 royalty-free voices, and MP3 downloads; free downloads are for personal use only. Starter is $9 a month, billed $108 yearly, and paid plans allow commercial publication of generated vocals. Audimee says uploaded audio and voice models remain private and inputs and outputs are not used for AI training unless separately agreed in writing.

NEUTRINO is an AI singing voice generator that synthesizes vocals from sheet music. Users provide lyrics and melody; the system estimates vocal timing, pitch, voice quality, and breathiness, then a vocoder produces the singing. The project says its models draw vocal traits from recordings made with performers' permission or audio released by public institutions, rather than existing pretrained models. The FAQ describes Muon voice retakes and adjustable quality and processing speed, with advanced, standard, and elements modes. Advanced and standard output is 48 kHz, 16-bit mono WAV; elements output is 24 kHz, 16-bit mono WAV. It is available for Linux, macOS, web, and Windows. Users download the software and add a voice library. NEUTRINO is free for general music and audio production, but embedding the software or using generated audio inside an application requires separate permission. Character-specific terms also apply to ordinary audio-file uses and vary by character and asset type. Users cannot currently create their own voice libraries with a released framework, according to the FAQ.
