=== AIVA === * '''主要功能''':AIVA(Artificial Intelligence Virtual Artist)是老牌的AI作曲平台,能够在数百种风格中创作音乐 (AIVA, the AI Music Generation Assistant)。用户可以选择预设风格(如现代交响、电子、爵士等)和情绪,AIVA会生成对应风格的乐曲,并支持下载为音频或MIDI以供后期编辑 (AIVA, the AI Music Generation Assistant)。AIVA 还允许用户上传''MIDI''或音频片段作为参考,生成相似风格的新曲,并提供一定的'''手动编辑'''功能(调整配器、修改音符等),达到“人机协作”作曲的效果 (AIVA, the AI Music Generation Assistant)。 * '''技术栈''':AIVA的核心是深度学习模型与传统作曲算法的结合。早期版本采用了基于深度神经网络的强化学习模型来学习配器和曲式,后端或使用Torch等框架。具体实现未开源,但从功能看,AIVA对音乐结构和风格的掌控较好,可能使用RNN/Transformer生成乐谱,再用虚拟乐器音源合成音频。整个系统作为云应用提供服务。 * '''API''':AIVA 针对个人用户提供网页版应用和桌面软件,而其API主要面向企业合作和高级用户。在'''企业方案'''中提供API访问和定制服务(需联系销售),允许集成AIVA的作曲能力到产品中。价格方面,个人使用有'''免费套餐'''(每月最多3段曲,非商用) (AIVA, the AI Music Generation Assistant)和付费订阅(标准€11/月、Pro €33/月 等 (AIVA, the AI Music Generation Assistant) (AIVA, the AI Music Generation Assistant))。企业API的费用未公开,预期根据使用规模和授权范围协商。由于AIVA生成每曲通常几分钟,其成本可以视为按首计算,每首成本随订阅下降,但折算后'''每分钟音乐成本在欧元分钱级'''。 * '''部署方式''':AIVA 以云服务形式提供。个人用户通过网页或App操作即调用云端生成。企业API集成时,也是通过HTTPS请求AIVA云端生成曲目然后获取结果文件。AIVA 不需要用户拥有高性能硬件,本地只负责发送请求和后续编辑下载的MIDI/音频。对于要求离线部署的客户,AIVA暂无公开支持(主要作为在线SaaS)。 * '''相关链接''':AIVA 官方网站:<nowiki>https://www.aiva.ai</nowiki> (AIVA, the AI Music Generation Assistant);AIVA 功能与定价页面 (AIVA, the AI Music Generation Assistant) (AIVA, the AI Music Generation Assistant)。 ''(备注:AIVA 是生成器中少数支持MIDI编辑和自定义风格训练的商业工具之一。)''
