立体声到环绕声上混，正确之选。
大多数上混插件都是为广播和后期制作而设计的，旨在将传统的立体声内容转换为环绕声，用于电视、流媒体和电影。它们通常通过提取虚拟的中央声道，并将剩余的环境信号扩散到后置扬声器来实现。但

这种方法不适用于音乐。立体声音乐混音层次丰富、动态十足。简单的声道提取会造成“单声道”问题——所有声音听起来都像是来自前方，环绕声道只有模糊的混响尾音。这并非沉浸式体验，只是声场更宽而已。UpM1xer

采用了一种不同的方法。它在频谱层面解构源信号，并智能地将能量重新分配到环绕声场中。UpM1xer 不采用简单的声像定位和延迟技巧，而是实时分析音频的频率成分、瞬态响应和立体图像，然后将元素放置在 3D 空间中它们自然的位置。

最终得到的环绕声上混效果听起来自然流畅，而非算法生硬。你的底鼓始终稳稳地位于中央。合成器音垫和纹理环绕着听众。混响尾音在高度声道中绽放。所有声音完美地折叠回立体声。

六款上混引擎，满足各种音源需求
。每种音源都需要不同的处理方式。UpM1xer 包含六款处理引擎——柔和、自然、宽广、深邃、提升和扩展——每款引擎都针对不同的空间扩展和沉浸感进行了调校。搭配六款支持音轨的配置文件（全混音、鼓组、人声、和声、合成器音垫、贝斯），即可根据您的音源进行匹配处理。

想将人声总线通过 7.1.4 Atmos 音轨？那就使用人声配置文件搭配柔和引擎。想将合成器音垫处理成高度声道？试试合成器音垫搭配扩展引擎。引擎和配置文件的组合，让您在调整任何参数之前，就能拥有 36 个初始设置点。没有任何其他上混插件能让您如此精准地控制立体声源在环绕声道中的分布。

专为 Dolby Atmos 音乐制作而打造的
UpM1xer 支持从四声道 (4.0) 到 7.1.4 的环绕声格式，包括音乐制作中常用的所有 Dolby Atmos 基础音轨格式：

5.1 – 标准环绕声；5.1.2

– 带顶部声道的 Atmos 基础音轨；

7.1 – 扩展环绕声；7.1.2 – Atmos基础

音轨（Loqic Pro、Pro Tools）； 7.1.4 – 带四个高度声道的完整 Atmos 基础音轨。无论您使用的是 5.1 还是完整的 7.1.4 格式，UpM1xer 都能处理所有 Atmos 基础音轨格式。使用“精确下混”模式可实现 100% 符合 ITU 标准的下混兼容性——验证您的环绕声混音是否可以无相位问题或电平变化地折叠回立体声。直观的控制，专业级的效果。UpM1xer是一款让您轻松掌控一切的上混插件。

简易模式 – 简化的控制，快速获得结果。选择引擎，选择配置文件，即可完成。

Stereo to surround upmixing, done right
Most upmixer plugins were designed for broadcast and post-production – converting legacy stereo content into surround for TV, streaming, and film. They typically work by extracting the phantom center channel and diffusing the remaining ambient signal to the rear speakers.

That approach falls apart with music. Stereo music mixes are dense, layered, and dynamic. Simple channel extraction creates the “big mono” problem – where everything sounds like it’s coming from the front, with vague reverb tails in the surrounds. Not immersive. Just wider.

UpM1xer takes a different approach. It deconstructs your source signal at the spectral level and intelligently redistributes energy across the surround field. Instead of simple panning and delay tricks, UpM1xer analyzes the frequency content, transient behavior, and stereo image of your audio in real time – then places elements where they naturally belong in a 3D space.

The result is a surround upmix that sounds intentional, not algorithmic. Your kick stays anchored in the center. Pads and textures wrap around the listener. Reverb tails bloom into the height channels. And it all folds back down to stereo perfectly.

Six upmixing engines for every source
Every source needs a different touch. UpM1xer includes six processing engines – Subtle, Natural, Wide, Deep, Elevated, and Expansive – each tuned for a different level of spatial spread and immersion. Pair these with six stem-aware profiles (Full Mix, Drums, Vocals, Harmonic, Pads, Bass) to match the processing to your source material.

Running a vocal bus through a 7.1.4 Atmos bed? Use the Vocals profile with the Subtle engine. Processing a synth pad for height channels? Try Pads with Expansive. The combination of engine and profile gives you 36 starting points before you touch a single parameter. No other upmixer plugin gives you this level of control over how your stereo source is distributed across surround channels.

Built for Dolby Atmos music production
UpM1xer supports surround formats from quad (4.0) up to 7.1.4, including all the Dolby Atmos bed track formats used in music production:

5.1 – Standard surround

5.1.2 – Atmos bed with top channels

7.1 – Extended surround

7.1.2 – Atmos bed (Logic Pro, Pro Tools)

7.1.4 – Full Atmos bed with four height channels

Whether you’re working in 5.1 or full 7.1.4, UpM1xer is the upmixer plugin that handles every Atmos bed format. Use Exact Downmix mode for 100% ITU-compliant downmix compatibility – verify that your surround mix folds back to stereo without phase issues or level changes.
