How SaaS Platforms Can Win the Feature Race with Stem Separation APIs

As the video and audio SaaS pie grows, so does the knife fight for each slice. Rapid market expansion invites new entrants, AI accelerates feature cycles, and buyers expect more for less, intensifying already fierce competition and forcing vendors to spend heavily to stand out and keep customers. 

The signals below show why the competition has become so fierce:

• The SaaS market is expanding at a breakneck pace, valued at roughly $273.55B in 2023 and projected to top $1.2T by 2032, drawing a flood of new entrants and intensifying competition;
• The number of SaaS companies has already climbed from 25,000 in 2021 to more than 30,000 in 2023, crowding categories with both specialist and generalist offerings that battle for attention and share;
• Nowhere is this fiercer than in go-to-market: many providers spend 50%+ of revenue on marketing and sales to differentiate, acquire, and retain customers. Video marketing SaaS is especially hot: by 2025, 89% of businesses use video, with rapid shifts toward short-form and multi-platform strategies pushing vendors to innovate relentlessly. The video/audio segment is even more dynamic, as AI-driven content creation, stem separation, noise removal, and real-time collaboration tools accelerate the feature race and raise the competitive bar.

What SaaS users expect vs. What it takes to build

Users now expect video and audio SaaS to match big-industry leaders. 

In practice, the bar now includes:

• high-quality recording and streaming (up to 4K video, uncompressed 48kHz audio, etc);
• remote multi-participant capture with separate tracks and team workspaces;
• advanced editing (text-based editing, automated clip creation like AI Video Cut, trimming, overlays, live media boards);
• enterprise-grade security (encryption, 2FA, compliance);
• AI-powered capabilities (transcription, noise removal, vocal isolation/instrument separation, auto-editing, personalized recommendations).

The rub: building this end-to-end takes months of R&D, specialized ML talent, and significant infrastructure spend, but teams are already overloaded and rarely have the resources to build from scratch. Meanwhile, growth targets won’t wait: you need to attract and retain users faster. That mismatch is widening the gap between “table stakes” expectations and what resource-constrained teams can realistically ship on time.

The SaaS feature race

The SaaS ecosystem in audio/video is now defined by feature velocity:

• Platforms that roll out advanced editing and cleanup tools attract creators faster;
• User churn increases if these functions are missing;
• Larger competitors set the benchmark with AI-powered functionality.

For instance, in audio/video SaaS, the feature race is relentless: a massive music-streaming market worth roughly $46-47B and hundreds of millions of paying users keeps the stakes high, with Spotify still the pace-setter (~31% global share), followed by Tencent Music (~14.4%) and Apple Music (~12–13%). 

To defend and grow share, leaders roll out AI-powered capabilities fast setting user expectations for advanced editing, stem separation, denoising, transcription, smart highlights, voice cloning/TTS, and real-time noise suppression. Platforms that deliver these features quickly attract creators and reduce churn; when they’re missing, users defect. Rather than building everything from scratch, teams increasingly integrate specialized APIs, for example, LALAL.AI for studio-grade stem separation and noise removal, to accelerate time-to-market and meet the bar set by bigger players.

For lean teams, this creates a dilemma: invest scarce resources into developing complex DSP/ML tools, or risk falling behind.

Stem separation for SaaS: what it is and why it matters

Stem separation is the process of splitting a mixed audio track into its individual components, such as vocals, drums, bass, and instruments, using AI or signal processing techniques. This allows each element to be isolated and edited independently, enabling applications like remixing, noise reduction, and overall audio enhancement.

The music stem separation SaaS market is growing rapidly, with a projected CAGR of 21.8% from 2025 to 2033, driven by demand across content creation, localization, podcasting, and remix applications. By integrating stem separation APIs, SaaS platforms can tap into this growth, adding advanced audio editing capabilities without heavy in-house R&D, accelerating time to market, and boosting user satisfaction.

For SaaS platforms, stem separation enables multiple high-value applications:

• Podcast platforms: deliver clean voices and remove background noise.
• Video editors: isolate dialogue for dubbing, localization, or mixing.
• Music apps: create karaoke tracks and remix stems for creators.
• Localization services: separate voice tracks from mixed media for faster translation.

It is one of the most requested premium features for creators - but also one of the hardest to build in-house.

The build vs. buy barrier

Building stem separation tech internally means:

• Recruiting ML/audio engineers
• Training models on large datasets
• Optimizing for speed and quality
• Maintaining infrastructure for heavy audio processing

That’s months of work and high ongoing costs. Most startups can’t afford to delay their roadmap for that long.

The API solution: plug-and-play stem separation

Stem separation APIs create value across a variety of SaaS products by enabling advanced audio processing without heavy in-house development. 

Key examples include:

• Video editors - isolate dialogue for dubbing, mixing, or localization;
• Podcast platforms - deliver cleaner voice tracks and remove background noise automatically;
• Music services - offer karaoke features, remixable stems, and creator-friendly editing tools;
• Localization SaaS - separate voice tracks from mixed media to accelerate translation and global content adaptation.

By integrating stem separation via APIs, SaaS companies can quickly expand their feature sets, improve user satisfaction, and strengthen their competitive edge while keeping development costs low.

Instead of reinventing the wheel, SaaS teams now turn to ready-to-use APIs like LALAL.AI API.

What it offers:

• 1-day integration - lightweight API with full documentation;
• No extra load on your team - no ML models to train or maintain;
• Scalable infrastructure - processes audio fast, at production scale;
• Enterprise-grade output - quality matches expectations set by top-tier platforms.

This approach lets SaaS products add “premium-grade” audio tools without slowing down the core roadmap.

For instance, according to Slate, using LALAL.AI’s API has been:

“At the moment, we're in the process of adding LALAL.AI into our tool, so when any of our mobile apps needs it, it gets available through a single access point.”

“The quality of vocals is just not comparable to your product, when it comes to separation; it’s incredible. I was using LALAL.AI a lot at home… I'm always really impressed by the results.”

Together, these points show how ready-to-use APIs don’t just speed up integration but also deliver the level of quality users expect, helping SaaS platforms offer advanced features without slowing down their core development

And because such solutions are designed for scalability and ease of use, teams avoid the burden of building complex AI pipelines themselves.

ROI of API Integration

Integrating stem separation APIs into SaaS platforms delivers substantial ROI, combining business growth with operational efficiency. Instead of investing months of development time and budgets exceeding $100K to build similar AI features internally, SaaS teams can leverage pre-built APIs to cut both upfront and ongoing engineering costs.

Some of key benefits include:

• Cost savings - lower in-house R&D expenses and reduced engineering overhead;
• Faster time to market - API integrations can accelerate launches by 3–6 months compared to building features from scratch, driving earlier user acquisition and revenue;
• Attracting new users & revenue growth - premium features like advanced audio editing out of the box draw in creators who actively seek cutting-edge tools. APIs open the door to new monetization models such as premium tiers, pay-per-use, or revenue-sharing;
• Operational efficiency - automated AI-powered separation reduces manual post-production, lowering support costs while improving scalability;
• Market competitiveness - with the SaaS integration market expected to exceed $15B by 2025 (CAGR 20%), embedding AI features like stem separation helps platforms stay ahead of user expectations.

Thus, integrating stem separation APIs isn’t just a technical enhancement - it’s a clear business case. SaaS companies can attract more users with premium features, increase retention and engagement, accelerate product roadmaps, and unlock new revenue streams, making this integration a strategic investment for growth in 2025.

Smart integration as the future of SaaS

For SaaS platforms in video and audio, stem separation and noise removal are no longer optional add-ons: they have become baseline expectations. Building such features in-house is costly, resource-intensive, and slows down product roadmaps.

By leveraging ready-to-use solutions like the LALAL.AI API, founders and CTOs can integrate enterprise-grade audio capabilities into their products in a matter of days rather than months. This approach not only saves development resources, but also ensures that platforms meet the high standards of today’s creators and users.

The future of SaaS in audio and video will not be defined by who builds everything from scratch, but by who integrates the smartest tools fastest - delivering premium features out of the box while keeping teams focused on core value.
