Audimee vs Sinsy

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.

Sinsy is a free web service that generates singing vocals from musical scores. You upload a MusicXML score, choose a vocal, and adjust settings labeled ALP, VIB, and PIT; Japanese appears as a language option. The system uses DNN- and HMM-based synthesis to model characteristics such as pitch and timbre, rather than accepting vocal input. Sinsy was developed by the Tokuda, Nankaku, and Hashimoto Laboratory. Its version history lists version 5.1 on 2026/05/01, with fixes for parameter-panel and smartphone/tablet behavior. Earlier entries record compressed MusicXML upload support in version 4.4 on 2023/12/25 and the addition of Japanese DNN vocal f01027j_dnn_beta5 in version 4.5 on 2024/12/25. The service is listed for web and Linux. Its Free online synthesis plan costs nothing. The synthesis page says using the service implies agreement to its terms of use. The about page is available in Japanese and describes the research background and version history.
