Howard Lerman, co-founder and CEO of Yext, has a new startup called Wonder Inventions, which officially launches its first product today – Dynascore.

Let’s focus on Dynascore first. Lerman said he and his team created the product to address the problem of the ever-growing demand for video content, which often relies on stock music. But by its nature, stock music isn’t designed for a specific video or length of time, which can lead to difficult adjustments, or force producers to edit their videos to match the music, because ” you can’t just cut three seconds out of a song and put it together.

However, Dynascore can take an existing piece of music and fit it into a video of any length. It can also adjust the music to place transitions, pauses, and endings where you want.

Lerman and his team demonstrated this to me, by taking a fitness ad and fitting different pieces of music to it, as well as adjusting the duration of the ad and where the transitions went. Each time, Dynascore would generate a new version of the track that went well with the commercial (although I have a feeling that if you picked the wrong song for the video, no adjustments can help).

To achieve this, Lerman said Dynascore examines a song and breaks it down into “the smallest unit of music that makes musical sense”, which he calls a “morphone.” So depending on the spec, he can put these morphones together in a way that maximizes what the company calls “musicoherence” – essentially, to make sure the stream continues like a real song.

Lerman pointed out that Dynascore’s technology doesn’t try to write music from scratch. Instead, he adapts human compositions – there are Masterworks, aka classic compositions that are in the public domain, as well as around 1,000 original compositions to start with.

“A lot of companies are using AI to write music,” he said. “They train their models on Bach, Mozart and Beethoven, but what comes out is garbage […] The critical breakthrough we’ve made is that computers can’t write music, the same way AI can’t write a movie and can’t write a book. But AI can reconstruct music in a way the human ear responds to. “

After a free trial, the price of Dynascore starts at $ 19 per month. It is available as a desktop application for Mac and Windows, as well as an extension for Adobe Premiere Pro editing software. The company has also built a developer API to integrate with other applications, starting with video builder Biteable and marketing production tool Rocketium.

Dynascore is just the first product we should from Wonder Inventions, which Lerman says will develop a whole portfolio of new products.

“We don’t start Wonder Inventions for one idea,” he said. “Wonder Inventions are 20 master inventors who are some of the most creative and brilliant people we have ever met, and they will develop many products that will have synergies.”

Lerman himself is president of Wonder while he remains CEO of Yext, which he described as his full-time job. When asked if there was a unifying vision for the business beyond just creating cool stuff, he replied, “Thirty years ago when people started a business, it turned out. was acting from the company. Now when a business is started it’s about the product, ”which he attributes to the fact that venture capitalists are focused on a single, scalable idea.

“I don’t think any venture capitalist would fund Dynascore – it’s too ridiculous and someone would watch [total addressable market] and say, “I don’t think that’s a multi-million dollar category,” Lerman continued. He doesn’t necessarily disagree with that assessment, but added, “It can be a great first product, with more success to come.”
