The Hybrid DSP Architecture

Engineered for Musical Depth, Guarded by Science

Most automated mastering tools rely on cold linear limiters that flatten transient punch. SELAH unites non-linear analog physical modeling with mathematical precision guardrails.

Harmonic Core

Class-A Triode Saturation

Asymmetric waveshaping mathematically generates 2nd and 4th-order euphonic harmonics, adding incandescent amber thickness to bass and vocal presence.

Non-Linear Waveshaping
Analog Respiration

Vari-Mu Optical Dynamics

Adaptive attack and optical decay envelopes breathe with tempo changes and sudden drops, avoiding the lifeless pumping artifacts of static digital limiters.

Program-Dependent Dynamics
Spatial Imaging

Stereo Matrix & Mono Anchor

Low frequencies below 120Hz are phase-collapsed to rock-solid mono for club subwoofers, while stereo side information receives an airy high-shelf shimmer.

120Hz Mono Foundation
Inter-Sample Defense

Aegis True-Peak Shield

4x polyphase oversampling anticipates inter-sample clipping before streaming lossy AAC and MP3 transcode encoders introduce distortion artifacts.

Frequently Asked Questions

Clear Answers for Discerning Creators

How does SELAH differ from standard automated limiters?

While automated web mastering platforms rely on standard digital brickwall limiters that push gain until transients smear, SELAH combines adaptive Vari-Mu optical compression (which breathes musically with tempo) with non-linear triode tube saturation, adding warmth and stereo separation while strictly guaranteeing an inter-sample ceiling under -1.0 dBTP.

What file format should I upload for best results?

We recommend exporting your final stereo mix as a 24-bit or 32-bit float WAV or AIFF at 44.1kHz or 48kHz. Ensure your mix bus has at least -3dB to -6dB of headroom and that no hard clipping limiters are active on your master fader.

Do you take any rights or royalties from my music?

Never. You retain 100% of your copyright, master rights, publishing, and royalties. SELAH is strictly an audio engineering utility platform under Creative Works Studios LLC.

Will my masters be compliant with Spotify, Apple Music, and streaming services?

Yes. Our engine adheres strictly to ITU-R BS.1770-4 standards. Every export guarantees a True Peak ceiling of -1.0 dBTP or lower to eliminate clipping during lossy transcode encoding on Apple Music, Spotify, TIDAL, and YouTube.
