SoundID VoiceAI is a DAW plugin that transforms recorded vocals into different singing voices or instruments using AI models. Known primarily for room calibration software, Sonarworks (well known for their SoundID Reference) launched VoiceAI in May 2024 as its first vocal transformation tool, and the plugin has since built a user base of tens of thousands of creators worldwide.
The workflow is straightforward: load the plugin on your vocal track, capture the audio, select a voice or instrument model, and render a new take that preserves your timing, phrasing, and pitch information while swapping in a completely different vocal character. The plugin runs inside your DAW as a standard VST3, AU, or AAX insert, which makes it much faster than bouncing audio to web services or standalone apps.
Producers report that the inflection tracking is notably accurate, with syllable emphasis, drawn‑out phrases, and timing all carried over to the new voice. The plugin won’t fix pitch issues, so you still need to tune your source material, but once that’s handled, VoiceAI delivers usable vocal takes that sit well in dense arrangements with minimal additional processing.
VoiceAI goes freemium
Sonarworks has turned SoundID VoiceAI into a true freemium product, adding a permanent free tier with no credit card, no time limit, and no usage cap. The freemium mode runs entirely locally, so there is no token system or cloud dependency for the included content, which makes it much more attractive for everyday DAW use.
The free tier gives you 8 presets, split between 4 vocal models and 4 instrument or creative presets, all usable as a standard plugin inside your DAW. This is clearly aimed at sketching songs, building quick demos, trying character voices, or roughing out vocal production without committing to extra spend.
For producers who already work with scratch vocals or reference takes, this removes a significant friction point, since you can now audition vocal ideas in different characters without renting session singers or burning through paid tokens.
Korean Voices expansion for K‑POP
Alongside the freemium launch, Sonarworks is introducing a Korean Voices Expansion Pack that adds 10 new voices, 5 male and 5 female. These were developed with Korean artists in a Seoul studio to capture tonal qualities, articulation, and emotional nuances that match modern K‑pop and Korean vocal performance.
Sonarworks is pitching these voices for K‑pop songwriting, anime and game audio, J‑pop and electronic genres, and any producer who wants a genuine Korean vocal flavor in the stack. All models are ethically sourced, royalty free, and built from professional sessions, which should reassure writers and labels who worry about murky AI voice licensing.
The Korean expansion follows previous Rock and Kids voice packs released earlier this year, showing that Sonarworks is actively expanding the voice library in genre‑specific directions rather than just adding generic tones.
Creative workflow and real‑world use
SoundID VoiceAI is positioned as a helper rather than a vocalist replacement, with Sonarworks explicitly framing it as a tool for demos, temp vocals, pre‑production, and sound design. The company says all contributing singers gave explicit consent and were fairly compensated, and the resulting voices are licensed royalty free for commercial work.
In practice, this sits in the same space as renting a session singer for scratch takes, but with the speed of a plugin and the option to flip between multiple characters on the same MIDI or audio line. Producers testing the plugin on trap, electronic, and pop projects report that processed vocals blend naturally in dense mixes, though they can still sound slightly artificial when fully exposed or soloed.
The voice‑to‑instrument feature is particularly useful for quickly mocking up melodic lines. You can hum or sing a saxophone, string, or guitar part, and VoiceAI will convert it to a playable instrumental line that follows your phrasing and dynamics. This works well for sketching ideas or creating reference tracks for session players, and with the right processing it can sound surprisingly organic.
Combined with the existing Unison feature, which can generate layered harmonies and stacks, VoiceAI pushes towards full vocal arrangement from a single recorded line. The Unison mode lets you create doubles, harmonies, or choir effects with adjustable pitch, timing, and stereo width, though it can be CPU‑intensive when rendering eight voices at once.
Pricing and availability
SoundID VoiceAI Freemium is available now directly from Sonarworks as a free download with unlimited use of the 8 included presets. Creators who want the full library can start a 7‑day enhanced trial that unlocks all 90+ voice and instrument presets, Unison, and includes 9,000 tokens for cloud processing during the trial period.
The Korean Voices Expansion Pack is priced at $29 and can be added on top of the freemium install or the full version. SoundID VoiceAI is also sold as a perpetual license through Plugin Boutique for $59 until January 1 (50% OFF!), which includes unlimited local processing and access to the full preset library without any ongoing subscription or token costs.
