About Spectrahertz
Spectrahertz — Most AI music generators (like Suno v5, Udio, Producer.ai or ElevenLabs) leave behind a distinct "spectral signature", a metallic high-frequency hiss, grain or shimmer that marks the track as AI-generated and lowers its quality. Spectrahertz identifies and surgically removes these artifacts without damaging the core melody or vocals, delivering a pristine audio signal ready for Spotify, Apple Music or video synchronization. Beyond restoration, it offers forensic protection tools: creators can detect hidden watermarks in incoming audio to verify authenticity, or embed their own invisible, robust fingerprints to protect their intellectual property before release. Operating on a flexible pay-as-you-go credit system, Spectrahertz is the "Swiss Army Knife" for the modern AI producer, eliminating the need for expensive DAW plugins or subscriptions.
Top use cases
- Suno Artifact Removal: Specifically trained models that target and remove the "metallic shimmer" and high-frequency noise common in AI generated music
- Forensic AI Detection: Analyze any audio file to determine if it was AI-generated
- Invisible Watermarking: Embed imperceptible ownership data into your tracks that survives compression and file conversion.
- Spatial Audio Upscaling: Convert flat, mono AI outputs into immersive Stereo or Binaural 3D audio.
Built for
Key features
- Artifact Removal: A dedicated restoration engine that removes unwanted artifacts, noise, and imperfections from AI-generated tracks while preserving the original audio quality.
- AI Music Detection: Advanced algorithms that detect AI-generated audio and identify hidden watermarks with high precision accuracy.
- Watermark Embedding: Protects your intellectual property by embedding custom, robust watermarks that remain imperceptible to listeners but detectable by forensics.
- Stereo Widening: Professional stereo enhancement using frequency-dependent widening. Users can select between Low, Medium, or High width settings to fix narrow AI outputs.

Frequently asked questions
What audio formats do you support?
We support MP3, WAV, and FLAC files up to 100MB. All files are processed and delivered as high quality 24bit - 48khz WAV.
How long does processing take?
Most files are processed in under 2 minutes. Processing time depends on file size and the tool selected.
Do credits expire?
No! All credits are valid forever. Buy once, use whenever you need. No subscriptions, no monthly fees.
How does the watermark detection work?
Our AI analyzes the spectral fingerprint of your audio to detect hidden, inaudible watermarks with 99.9% accuracy. The process is non-destructive and provides a detailed report.
How does the artifact removal work?
Our AI identifies and removes common artifacts from AI-generated music, including digital shimmer, metallic resonances, unwanted frequencies and spectral anomalies. The process preserves the natural character of your audio while eliminating unwanted artifacts that can make tracks sound synthetic or processed.
is my audio data secure?
Absolutely. We use zero-knowledge encryption and we never listen to, share, or use your audio for training purposes.
Can I use this commercially?
Yes! All processed audio is yours to use commercially. We retain no rights to your content.
What if my processing fails?
If processing fails due to a system error, your credits are automatically refunded. If the file is incompatible or corrupted, you'll receive a detailed error message before any credits are charged.
