AI Song Creator vs SoulX-Singer

AI Song Creator is a web service for making complete songs from text prompts or lyrics you supply. It can generate melody, rhythm, vocals, or instrumentals, with tracks up to 8 minutes long. You can set genre, mood, tempo, instruments, and structure, then export finished music as WAV or MP3. Paid plans offer higher bitrates. The site also lists tools for AI lyrics, singing voices and song covers, as well as vocal removal, stem splitting, mastering, and audio-to-MIDI conversion. The free plan costs nothing and allows two songs and one music generation per month, with one task at a time and personal-use rights. Basic costs $10.49 a month, Standard $20.99 a month, and Premium $34.99 a month. Tracks generated under paid plans include a commercial license; annual subscribers can download a certificate for each eligible track. The service is aimed at creators including YouTubers, podcasters, filmmakers, and musicians. Support is by email Monday to Friday, with replies typically within 48 business hours.

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.
