FAQs about AI audio upmixing

Audio upscaling refers to a process that uses AI or advanced signal processing to improve the quality of low-resolution or compressed audio files. Unlike traditional methods that simply increase the sample rate by inserting zeros, AI audio upscaling predicts and reconstructs missing high-frequency details from low frequencies. This AI audio upscale makes the sound clearer, more detailed, and closer to a high-resolution format, enhancing the overall listening experience.
Stereo uses two channels, left and right, for a two-dimensional audio experience suited to music and everyday listening. Surround sound uses multiple channels, such as 5.1 or 7.1, to create a more immersive, three-dimensional sound for movies and home theaters.
AI analyzes stereo audio and distributes dialogue, ambience, and effects across multichannel layouts such as 5.1 surround sound. The added center and rear channels create a wider soundstage for films, music, and games without manual channel mixing.
For audio enhancement, we recommend the following configuration:
Operating system: Windows 11 or Windows 10, 64-bit only;
system memory: 16 GB RAM or more;
graphics card: NVIDIA RTX 30 Series or newer with 8 GB VRAM;
CPU: 8th-generation Intel Core i7 or AMD Ryzen 3000 Series or newer.
