Sonauto

tool describes

SonautoIt is an AI music platform that is generated for free and unlimited. It focuses on "songs can be produced in 3 minutes even with no music foundation." The core uses text/lyrics/melody to generate professional-level BGM, covering Douyin/TikTok popular styles (such as exploring shops, light electronics, emotional Lyrical folk songs). Technically, it adopts the Melodia diffusion model and supports the consistent generation of lyrics (such as inputting "Autumn Milk Tea Shop" and automatically adding "Warm Female Voice + Guitar Melody"). It has served more than one million users, 60% of whom are Short Video creators. Although the official website is simple, MP3s can be directly generated and downloaded through external tools, seamlessly connecting cut/CapCut, solving the pain point of "BGM is difficult to find and the version is powerful".

core functions

• Scene-based style generation: Enter keywords such as "Douyin Shop Hot Models" and "TikTok Card Point Electronic", and AI automatically matches rhythm (128BPM) and musical instruments (electronic drums + synthesizers) to generate exclusive BGM for 15-30 seconds for Short Video; ​
• Double generation of lyrics + melody: Enter the theme (such as "decompressing the workplace"), and simultaneously produce rhyming lyrics + corresponding melody. It is suitable for oral broadcast of knowledge Short Video (such as "Don't want to go to work on Monday? AI will help you write a song about fishing "); ​
• Zero-threshold editing tool: Drag and drop to adjust the paragraph structure (Prelude-Main Song-Chorus), change speed (0.8-1.2 times), support uploading reference music (such as "imitating a popular chorus"), which is 90% simpler than professional software; ​
• Inspiration library for community hits: The popular list is updated in real time,"Douyin BGM" and "Fast Hand Emotional Hot Songs". You can reuse styles by clicking, and you don't have to worry about mass production of matrix numbers; ​
• Free commercial authorization: The generated music defaults to CC0 protocol and can be used for Short Video and live broadcasts (non-commercial performances) to avoid copyright disputes (compared with some tools, additional authorization is required).

usage scenarios

• IP person-specific music: Series videos (such as "AI Tool Recommendation") have a fixed style (such as "Technological Electronic Sound"), and account BGM is maintained through the "Reference Music" function; ​
• Live warm-up music: Generate "BGM with Goods" and "Interactive Question and Answer Melody" in real time to support on-site adjustment of rhythm and improve audience stay (such as "3, 2, 1 Link" exclusive drum beats); ​
• Low-cost matrix number operation: Batch generation of homogeneous content BGM (such as "Daily Book List" unifying piano melody), free and unlimited generation to reduce the cost of single item to 0 yuan; ​
• Cross-border content localization: Enter "TikTok Spanish Discovery Shop" to generate Reggaeton-style BGM, and the lyrics are automatically adapted to spoken Spanish, 10 times faster than translation + original.

applicable population

• Short Video creators/self-media people: Especially shop hunters, plot, and knowledge bloggers, they need to quickly match popular BGM on the platform, and the free quota can meet daily demand; ​
• Live broadcast operation team: It is necessary to change the warm-up music in real time and generate "scene keywords" at a second-level level to improve the interaction rate between live broadcasts; ​
• Newcomer/part-time music creator: No foundation in music theory, generate original BGM through text descriptions for personal accounts or customer orders (such as "helping merchants customize promotional BGM"); ​
• Cross-border self-media: Multi-language BGM is generated with one click (such as Thai and Indonesian) to solve the problem of difficulty in finding music in small languages and adapt to the TikTok Southeast Asian market.

Limitations (objective hints)

• Chinese lyrics to be optimized: Some scenes have stiff rhymes (such as "milk tea" with "cha"), so it is recommended to be used first for pure music or simple colloquial lyrics; ​
• Complex styles have limitations: niche genres such as symphony and jazz are generally restored and are more suitable for Short Video popular styles (electronic, folk, Trap); ​
• Insufficient naturalness of the vocals: The singing generated by AI occasionally has a "mechanical feeling". It is recommended to give priority to pure music or use it with real dubbing.
