The autonomous audio engineering suite. Orchestrated by Sigrun. Powered by Herja. Directed by You.
More than an interface. Sigrun is a conversational audio engineer residing in your browser. Dictate your vision or drop in a problem track, and she autonomously orchestrates the entire Nexus arsenal to execute the fix.
"I am detecting likely frequency masking below 250Hz. Upload the stem files. I will run a deep harmonic analysis and execute a surgical neural EQ pass to tighten the sub-bass."
"Confirmed. Upload the master file. I will isolate the vocal stem, recalculate the tempo and pitch shift by +3 semitones, then rebuild the master to maintain transient punch."
"Understood. Calling the Herja engine. Generating a 15-second heavily distorted, polyrhythmic industrial drum transition."
Most generators guess. Sigrun thinks.
Before synthesis begins, our 4B parameter LLM intercepts your prompt to compose the track's architecture: Calculating BPM, key, time signatures, and structural shifts. She compiles this logic into raw audio codes and hands them over to Herja for flawless and coherent execution.
Generate high-impact audio effects, cinematic hits, and brutal transitions. Designed for instant integration into professional mixing environments.
Execute complete, high-fidelity music tracks in a single generation. Dictate the genre, the grit, and the structural arrangement. Herja handles the execution.
Break the boundaries of standard generation. Seamlessly extend, stitch, and append generations together for massive cinematic scoring or extended arrangements.
This is the difference between guessing and composing. When you enable Sequencing, Sigrun steps in before a single audio waveform is generated.
Our 4B parameter language model intercepts your prompt to write a structural reasoning matrix. She calculates the optimal BPM, determines the musical key, and dictates the precise arrangement. This logic is compiled into raw acoustic blocks and fed directly into the Herja synthesizer.
An energetic and classic disco-funk track driven by a tight, four-on-the-floor drum beat and a prominent, funky slap bassline. Clean, rhythmic electric guitar chords provide a percussive texture, while a powerful brass section delivers punchy horn stabs...
Immortalize vocal identities. Upload up to 8 minutes of raw audio, and the system automatically isolates the vocal stem to map the unique timbre, cadence, and stylistic signature.
Assign metadata, attach a visual identity, and deploy your custom neural character across future generations with zero loss in fidelity.
Provide the source file (up to 8 minutes). Define the character's name, description, and upload the visual avatar.
The Nexus strips background instrumentals and surgically extracts three 10-second slices from the start, middle, and end of the timeline to capture maximum emotional range.
The neural character is permanently locked into your arsenal, ready to execute high-fidelity text-to-audio and music generation.
Achieve pristine, industry-standard loudness and tonal balance autonomously. Neural Mastering goes far beyond simple LUFS targeting and basic equalization curves. Sigrun deeply analyzes the frequency spectrum, phase coherence, and dynamic range of your raw mix. It automatically applies intelligent compression, subtle harmonic saturation, and precise stereo widening to ensure commercial viability. Whether preparing a track for streaming platforms or a club sound system, the mastering chain adapts to the specific genre constraints. The result is a loud, punchy, and transparent master delivered in seconds.
Master Audio Now →Isolate distinct stems with surgical precision using cutting-edge neural separation. The Nexus allows you to choose between multiple advanced model versions, tailoring the extraction quality to your specific requirements. Depending on the selected parameters, you can split a single master file into a massive 17 independent stem tracks. Extract pristine lead vocals, backing harmonies, drum transients, heavy basslines, and individual instruments without severe phase cancellation or digital artifacting. This provides unparalleled control for remixing, sampling, or rescuing old mixes where the original project files are lost.
Split Stems →Break down the core architecture of your sound with comprehensive, data-driven insights. Sigrun performs a microscopic examination of frequency spectrums, harmonic density, and stereo imaging. Beyond raw visual data, the analysis engine automatically identifies the precise musical key, detects the exact BPM, and provides a structured written summary of the track's sonic profile. This allows producers to quickly identify frequency masking, phase issues, or structural imbalances within their mixes. Make informed, highly technical decisions instead of relying purely on subjective listening environments.
Analyze Track →Transform spoken word or vocal performances into highly accurate, time-synced text arrays. The transcription engine supports multiple languages and exports directly to industry-standard subtitle formats including SRT, SBV, and TTML. For existing scripts, you can manually input your raw text, and the AI will autonomously time-sync it to the provided audio file. You also receive a clean, unformatted plain text file for standard documentation or lyric sheets. This entirely eliminates hours of tedious manual syncing for podcasts, cinematic trailers, and complex music videos.
Transcribe Audio →Generate high-impact, custom audio effects directly from highly descriptive text prompts. Tell the Herja engine exactly what you need, whether it is a heavy cinematic sub-boom, a glitchy sci-fi transition, or a hyper-realistic environmental Foley sound. The system synthesizes these effects from scratch, ensuring 100% royalty-free, unique assets that fit seamlessly into your mix. Tailor the duration and intensity of the effect to match your specific scene or transition point. It acts as an infinite, on-demand sound design library tailored specifically to your immediate creative requirements.
Generate AudioFX →Execute complete, high-fidelity music tracks in a single generation, including both raw instrumentals and full arrangements with generated lyrics. Utilize the proprietary Lego Feature to shatter the boundaries of standard generation limits. Seamlessly extend, stitch, and append multiple generations together to build massive cinematic scores or extended arrangements up to 10 minutes long. Furthermore, fully integrate your custom Neural Characters to define the exact vocal identity and stylistic signature singing the generated lyrics. Dictate the genre, the grit, and the structural arrangement while Herja handles the flawless execution.
