AI 伴奏提取器如何工作？
伴奏提取器会将混合歌曲中的主唱与伴奏部分分离，生成适合卡拉 OK、排练或翻唱使用的伴奏音轨。本页以伴奏为主要结果：上传音频后，模型会估算人声与伴奏部分，再由浏览器将鼓、贝斯和其他伴奏合成为一条音轨；你也可以试听或下载分离的人声。生成结果是 AI 对混音的估算，并非还原原始录音工程，因此混响、和声和频率重叠可能留下杂音。如果你主要想提取清唱人声，可使用人声分离页面。
三个简单步骤
如何移除歌曲人声并制作伴奏
02
使用 AI 分离人声
点击生成伴奏并保持页面打开，等待音频分离完成。一次处理会生成无人声混音和独立人声音轨。
03
试听并下载伴奏
在浏览器中试听伴奏音轨，再下载用于卡拉 OK 或练习；如果两种素材都需要，也可以保存人声音轨。
伴奏音轨可以用于哪些场景？
卡拉 OK 与练唱
从歌曲中分离主唱，制作适合跟唱、排练或练习乐器的伴奏。
翻唱与排练
录制翻唱前，先将伴奏作为练习参考。试听处理结果，确认它是否适合你的曲目和用途。
视频与音频剪辑
在剪辑中使用无人声音乐底轨，或单独处理歌曲伴奏。本页接收音频文件，暂不支持上传视频。
音乐制作与混音草稿
在编曲草稿或获授权的混音中单独聆听伴奏。分离结果是混音参考，不是原始录音室分轨。
还需要歌曲的其他部分？
可切换到以人声为主的工具，或将整首歌曲拆分为独立音轨。

What does an instrumental remover do?
An AI instrumental remover on this page removes the lead vocal from a song mix to create an instrumental backing track. It also returns the separated vocal, so you can preview or download either result.
How do I remove vocals from a song and keep the music?
Upload an MP3, WAV, FLAC or M4A file and choose Create instrumental track. The tool separates the vocal from the accompaniment, mixes the accompaniment into a backing track, and shows it first for preview and download.
Will this tool leave vocals or remove the vocals?
The main result is the instrumental version with the lead vocal reduced. A separate vocal track is also available. If you only want to isolate and work with the singer, use the Vocal Remover page instead.
Is this instrumental remover free to use?
Yes. This instrumental remover is currently free to use online, with no subscription or account required. To keep the service available, requests may be rate-limited.
Which audio formats and sizes are supported?
Upload MP3, WAV, FLAC or M4A files up to 50 MB and 10 minutes long. Browser and codec support can vary by device.
Can I use this tool to create a karaoke track?
Yes. It creates an instrumental backing track by separating the lead vocal from the accompaniment. Preview the mix before downloading it for singing or rehearsal.
Can I download the isolated vocals too?
Yes. The same separation job includes a vocal track as well as the instrumental backing track. The instrumental appears first on this page; use Vocal Remover if an isolated voice is your main goal.
Does the instrumental remover work with video files?
Not at the moment. This page accepts MP3, WAV, FLAC and M4A audio files. Extract the audio from a video first if you have the rights to process it.
How accurate is an AI instrumental remover?
Like any AI instrumental remover, it estimates which sounds belong to the voice and accompaniment; it cannot perfectly reconstruct a studio mix. Reverb, backing vocals and overlapping instruments can leave artifacts or vocal bleed.
Is my audio processed in my browser?
No. Audio is sent securely to an online service for separation. Temporary input and result files expire after one hour, and audio payloads are not stored in request history.
Can I use the instrumental track commercially?
That depends on the rights to the original recording and composition. Creating a backing track does not grant permission to sample, publish or sell copyrighted music; check your licenses before commercial use.
Can I separate drums or other instruments by themselves?
This page focuses on a combined instrumental backing track and the vocal. For separate drums, bass, guitar, piano and other instrument tracks, use the AI Stem Splitter.
