About this gig
Looking for pristine audio stems, clean vocal isolation, or custom backing tracks without watery artifacts or phase issues?
As a Telematics Engineer specialized in DSP and audio AI architectures, I deliver professional multitrack audio deconstruction using state-of-the-art models (BS-RoFormer, Mel-Band RoFormer, and HTDemucs 6s) paired with high-precision digital signal processing:
Lead Vocal vs. Backing Vocals: Surgical lead isolation while preserving original harmonies intact. Multitrack Stems: Pristine isolation of Drums, Bass, Guitars, Piano/Keys, and Other instruments. Custom Backing Tracks: Ideal minus-one rehearsal mixes for singers, music schools, and live bands. DSP Lab: Non-destructive pitch-shifting (+/-12 semitones) and tempo changes with zero phase distortion. Click & Lyrics: Sample-accurate synchronized click tracks and Whisper-based text transcription.
Unlike web converters that crush dynamic range and bleed frequencies, I run dedicated local pipelines to ensure maximum separation purity. All stems are delivered in uncompressed 16-bit/24-bit WAV format.
Send your audio file or link, and get your studio-ready stems!

FAQ
What audio file formats can I provide, and what will I receive?
You can send your audio in WAV, MP3, FLAC, AIFF, or even provide a direct link (such as YouTube or SoundCloud). You will receive pristine, uncompressed 16-bit or 24-bit PCM WAV stems, perfectly aligned from sample zero and ready to drop into any DAW or media player.
How is this different from automated web-based vocal removers?
Online tools introduce phasing and watery artifacts. I run local state-of-the-art AI (RoFormer, Demucs 6s) and DSP pipelines for maximum dynamic range and purity.
Can you keep backing vocals without the lead vocal?
Yes. Mel-Band RoFormer isolates the main voice while leaving backing harmonies and choirs intact, creating ideal practice and performance tracks.
Can you adjust the key or tempo of the stems?
Yes. My DSP lab shifts pitch +/- 12 semitones and adjusts tempo (0.5x–2.0x) without robotic artifacts, chipmunk effects, or phase distortion.
