Source separation is a technology that’s constantly evolving, and the latest company to promise a breakthrough are British developers Hit’n’Mix. The Infinity audio editor is a showcase for their TrueSource algorithm, which is said to go well beyond what’s possible with other packages. Rival source-separation programs usually employ cloud processing, but Infinity runs natively on a host Mac or PC; and unlike many alternatives, it can identify not only drums and vocals but individual instruments within a mix.
Applied to a mono or stereo audio file, the analysis process generates something Hit’n’Mix call a Rip, which displays the music on a kind of piano-roll display. The user can then lock, mute, isolate or modify individual notes and instruments — but Infinity’s capabilities go much further than merely ‘unmixing’ a source. The program includes Audioshop, a palette of tools inspired by image‑manipulation programs, that allows separate aspects of one part — pitch, timbre, formant, volume and more — to be ‘painted’ onto another. And if you need more flexibility, every aspect of Infinity is fully scriptable using Python, with an advanced scripting editor built in.
Infinity is available from Hit'n'Mix now at £299$299. We hope to review it as soon as possible!
