Audimee vs Nova-Vox

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.

Nova-Vox is a free, open-source vocal synthesizer for Windows combining traditional and AI-driven methods. Its ESPER framework supports concatenative and granular synthesis and provides a foundation for AI systems. Voicebanks can package expressions, pitches, custom AI models and settings in one file. The engine chooses a suitable pitch for each note, while expressions can be entered with a single letter. A universal phonetics system is described as supporting any language, and a node editor builds adaptive post-processing effects. The Nova-Vox 1.0 download includes the Development Kit and AI base models for creating Voicebanks, delivered through a Windows setup executable. Commercial use is allowed. The maker identifies Johannes Klatt as maintainer and lead developer. The maker also reports performance issues, a prohibitively large installation and code issues in version 1.0. Mirai, the planned 2.0 release, has no release date.
