BandBuddy 是一款在 iPhone 和 iPad 本机运行的音乐练习工具。导入自己的音频或视频,用 AI 分离声部,再按练习需要调整伴奏。 六轨分离与吉他细分 将音乐分为人声、鼓、贝斯、吉他、钢琴和其他六轨,还可继续细分为木吉他、主音吉他和节奏吉他。基础六轨完成后即可开始练习,吉他细分随后在后台继续处理。 灵活的练习控制 独立调节每轨音量、静音与独奏,支持 0.5×–2× 变速无变调、升降调、A/B 循环、进度拖动与快进快退。通过 Live House 调整声部空间位置,按自己的方式排练。 视频同步与全屏播放 支持导入 MP4、MOV、M4V 视频,本机提取音频并保留画面用于同步练习。全屏视频可跟随设备横竖屏旋转。 节奏与调性辅助 自动测拍、TAP 手动测拍、节拍相位微调、预备拍与节拍器音量控制,配合歌曲调性识别、波形及 LRC 时间轴歌词,帮助定位练习段落。 混音导出与曲库管理 按选定声部及当前混音设置导出 MP3,保存至“文件”。支持本地曲库、搜索、收藏、任务重试,以及锁屏和控制中心播放控制。 iCloud 同步 可在设置中开启 iCloud 同步,在登录同一 Apple 账户的设备间同步已完成的歌曲、分轨、歌词和练习设置。同步默认关闭,首次开启、App 启动和分轨完成时自动上传与下载。需要可用的 iCloud 账户、网络和足够的云端空间。建议不要在多个设备上同时使用,以降低同步冲突和数据受损风险。删除歌曲仅影响本机,云端副本保留。 本地处理与数据选择 模型需在 App 内下载,音频解码、AI 分轨及混音均在设备本机完成。音乐与练习数据默认保存在本机,仅在您主动开启 iCloud 同步后上传至您的 iCloud 私有数据库。请自行备份重要原始音频和导出文件。 请仅处理您拥有合法权利或已获授权的音视频;自动分离结果可能存在串音等偏差,适合练习与辅助参考。
