It is less suited for professional music producers requiring precise multi-track DAW sequencing, granular MIDI editing, or verified copyright clearance for mainstream commercial distribution. ## What it is Sonauto (now operating as Treblo) is an AI music generation platform designed to produce full songs from textual prompts, style tags, and lyrics. Powered by models such as Melodia v3, the platform generates complete tracks—including vocals, melodies, and instrumentation—in around 15 seconds, streaming playback while the remainder renders in the background. Users can write custom lyrics, use structural markers like [Intro], [Verse], and [Chorus], or have integrated language models generate lyrics automatically across dozens of languages. For non-vocal requirements, an instrumental switch disables vocal synthesis for background scoring, lo-fi beats, or podcast beds. The platform supports thousands of genre tags ranging from pop and hip-hop to drill, jazz, metal, and EDM, which can be combined to produce specific musical styles. In addition to initial song generation, the platform provides workflow utilities including song extension, inpainting, section-by-section regeneration, and stem separation. Output files can be exported without watermarks across multiple audio formats such as MP3, WAV, FLAC, OGG, and M4A. Songs can be kept private, shared via unlisted links, or published to community profiles and playlists. **What makes it different:** Unlike many generative audio platforms that enforce credit limits or lock commercial rights and lossless downloads behind paid tiers, Sonauto offers unlimited song generations with stem separation and multi-format downloads (including WAV and FLAC) for free, without vendor-imposed usage restrictions. **Best for:** creators who want fast, unlimited AI song generation across diverse musical genres without subscription fees or download format restrictions. **Not ideal for:** traditional recording engineers seeking raw MIDI files, track-by-track synth controls, or production teams requiring guaranteed third-party copyright indemnity. ## Key features - **Text-to-Song Generation** — Generates complete vocal or instrumental tracks from text descriptions, genre combinations, and mood tags in roughly 15 seconds. - **Custom and Automated Lyrics** — Accepts user-written lyrics with structural tags ([Intro], [Chorus]) or generates rhyming lyrics in dozens of supported languages. - **Post-Generation Audio Editing** — Enables song extensions, audio inpainting, lyric replacements, and selective section regeneration directly within the browser interface. - **Stem Separation** — Splits generated songs into isolated vocal and instrumental stems for customized remixing and level adjustment. - **Flexible Multi-Format Exports** — Permits direct audio file downloads in MP3, WAV, FLAC, OGG, and M4A formats without compression paywalls. - **Instrumental Mode** — Disables vocal synthesis to generate pure instrumental tracks for video game soundtracks, background audio, and podcast scoring. ## Use cases - **Custom Songs for Personal Occasions** — Composing personalized songs for birthdays, weddings, or anniversaries using personal jokes, names, and specific genre styles. - **Royalty-Free Video & Podcast Backgrounds** — Generating bespoke instrumental music beds, intro stings, and ambient tracks for social media videos and audio productions. - **Rapid Songwriting Prototyping** — Testing how original lyrics sound against diverse musical styles, tempos, and vocal arrangements before going into studio recording. - **Indie Game Soundtracks** — Creating multi-genre soundtrack assets, battle themes, and atmospheric lo-fi tracks on a tight development budget. ## Pros - Unlimited song generations with no credit paywalls or daily generation caps - High-fidelity download options including WAV and FLAC alongside MP3 and OGG - Built-in stem separation and inpainting features available on the free tier - Generates music and lyrics across dozens of international languages ## Limitations - Consumer inputs may be used to train and improve generative models according to the privacy policy - Brand transition from Sonauto to Treblo may cause confusion regarding domain and naming consistency - Lacks granular DAW-level MIDI controls and virtual instrument track isolation ## Pricing As of September 8, 2026, the service is advertised as completely free ($0.00) with unlimited song generations on its latest model, multi-format downloads, and no commercial usage restrictions imposed by the vendor.
