Audimee vs SoulX-Singer

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.

SoulX-Singer is a singing voice synthesis model that generates voices for singers it has not been tuned on. Pitch, rhythm, and expression can be guided by melody-conditioned F0 contours or score-conditioned MIDI notes. Its voice-conversion system changes raw singing audio to a target singer’s voice while retaining melody, rhythm, and lyrics, without requiring lyric or MIDI transcriptions. It supports Mandarin Chinese, English, and Cantonese, plus singer-timbre cloning, cross-lingual synthesis, and lyric editing while retaining natural prosody. Preprocessing tools handle vocal separation, dereverberation, F0 extraction, voice activity detection, and lyric and note transcription. Users can edit MIDI metadata, including lyrics, phoneme alignment, pitches, and durations, before synthesis. Soul-AILab provides generation and conversion demos and a separate MIDI editor through Hugging Face Spaces; the repository also supports local inference. Code and model weights use the Apache 2.0 license. Maintainers caution that automatic preprocessing may misalign singing with lyrics and notes, so manual correction may be needed.
