But more options mean more complexity and more skill needed by the operator to extract the vocals. Trax Pro SP is Audionamix's legacy product that's most advanced in terms of options. I started with Trax Pro SP because I assumed Pro means better – right? Well yes and no it turns out. After meeting with the nice folks at Audionamix during AES, this seemed like a good test for their software and services. We did however have the two-track mix from the front of house console. To make a long story short, the band's crew shorted out our split in between sound check and the show, so we lost the vocal feed on the first two songs of the multitrack. I recently helped produce a live recording of a band at The Fillmore in San Francisco.

The second, more forensic category, is for those folks who hope they'll never need this software but then something comes up and they do need it. Being able to pull out a vocal from a snippet of music and then sample and loop it could be huge for those producers. Copyright infringement aside, being able to pull stems from music will be super useful to people working in electronic, pop, and hip-hop genres. There are two basic uses of this kind of product, one creative and one forensic, so in general this will appeal to two different types of users. These products are both based on being able to take a stereo mix of a song and separate out the vocals from the music, and even separate the music from the drums.

Welcome to the brave new world of DSP! Along with folks like iZotope, Audionamix is on the cutting edge of spectral based DSP technology that can do previously unheard of things with audio.
