After Apple discontinued its Music Memos app favored by musicians for creating track concepts, a brand new startup known as Tape It stepped in to fill the void with an app that leveraged AI to mechanically detect the instrument and annotate the recording. Now that startup is taking the subsequent step in its journey to enhance the audio-recording course of with the introduction of an automated, studio high quality noise discount algorithm, additionally powered by AI, that works on any audio — not simply speech.
The AI denoiser shipped this week as a free net app, with a plan to license the expertise to distributors sooner or later. It’s going to additionally later be built-in into the corporate’s flagship Tape It app, the corporate says.
Based in 2020 by musicians and mates Thomas Walther and Jan Nash, Tape It’s preliminary focus was on an iOS recording app for musicians. Earlier than creating Tape It, Walther had spent three and a half years at Spotify after it acquired his audio detection startup Sonalytic. Nash, in the meantime, is a classically skilled opera singer, who’s additionally a bassist and engineer. The duo had been initially impressed to construct Tape It as a result of it was one thing they wished for themselves as fellow bandmates that may be as easy to make use of as Apple’s Music Memos, however made extra highly effective by way of the usage of AI.
The unique model of the app was capable of mechanically detect the instrument, after which annotate the recording with a visible indication to make these recordings simpler to seek out by searching for the colourful icon. Musicians might additionally add their very own markers to the recordsdata, in addition to notes, and pictures to assessment afterward.
The app has since gained traction with round 10,000 month-to-month lively customers, the corporate says.
However as Walther informed TechCrunch on the time of Tape It’s 2021 debut, the group aimed to broaden their use of AI over time.

That led to the startup’s newest improvement — an AI-powered denoiser they’ve been constructing over the previous two years. The problem with recordings, the corporate explains, is background noise. To be able to cut back environmental noise and electrical interference, musicians file in studios and leverage advanced software program. Tape It needs to offer a extra reasonably priced different utilizing AI. Their software program mechanically removes noise like hums and hisses, not solely spoken phrase, with the aim of manufacturing studio-quality outcomes on songs, single-instrument tracks and subject recordings.
“What we developed is we created an automated model of the denoising software program that you’ve got been discovering in skilled recording studios within the final 15 years,” explains Walther.
To confirm its outcomes, Tape It’s releasing an academic study with a scientific listening test that exhibits the software program’s high quality in competing with industry-leading denoisers.
In a video, the corporate explains that whereas speech enhancement programs have superior considerably, they typically solely work for speech and warp or corrupt music alerts. In the meantime, skilled denoising programs require handbook management of advanced software program by skilled customers. Tape It’s expertise includes connecting a neural community controller to a sign processing-based noise discount algorithm. This allowed for automated denoising of basic audio alerts, together with music. The corporate plans to current its work on the AES convention subsequent week.
“The explanation individuals haven’t automated these [professional systems] is as a result of you may’t historically put them right into a neural community…you may’t practice such a system,” notes Walther. “We are literally the primary ones to coach such a system and that’s why we’re fairly enthusiastic about this bigger space.”
He provides that the educational group will probably be much less within the denoising product itself however extra in how they managed to get it to work this manner due to the implications it has for different functions of automating studio software program.
Nonetheless, the denoising software program already has some potential prospects, together with a big studio software program vendor and a big {hardware} producer. In these circumstances, enterprise pricing shall be made accessible however for smaller startups, cheaper plans shall be provided.
“Everybody is happy about AI being artistic,” mentioned Walther, when asserting the information. “We’re enthusiastic about AI fixing boring issues. We deal with background noise, so you may solely give attention to the artistic elements and write extra songs,” he mentioned.
AI applied sciences aren’t solely getting used to scale back background noise for musicians, after all, different firms are additionally turning to AI to create near-studio high quality sound for podcasters too. For instance, Podcastle simply this month launched its Magic Mud AI, a generative AI software that eliminates background noise and enhances its dynamic vary.
Tape It’s five-person group relies in Berlin, London, Los Angeles and Stockholm, and consists of designer and musician Christian Crusius, beforehand of the design consultancy Fjord, which was acquired by Accenture. The majority of the work on the denoising software program was accomplished by Christian Steinmetz, a PhD researcher in AI and audio.
The corporate is continuous to bootstrap, having beforehand turned down affords of funding.
“That is elementary analysis and we simply didn’t know the way lengthy it could take,” Walther defined as to why they went this route. “We thought it was a bit dangerous if you happen to get an investor who isn’t that affected person — [they’d push you to ] simply take an open supply mannequin and transfer on. However we wished to have a bigger technological benefit,” he mentioned.
The corporate is now contemplating elevating funds and is having these discussions, given the tempo of the AI market, however hasn’t made any formal determination as of but.
