# I Will Create AI Synthesised Vocals for Your Demo or Production

Whether you need a convincing demo vocal to pitch your song, seamless harmony layers to sit beneath a real performance, or a full synthesised lead vocal for your production, AI vocal programming delivers a fast, flexible, and professional solution — without the cost or scheduling complexity of a studio session.

Zinn Digital, based in London, England, uses professional off-the-shelf voice databases to synthesise English vocals tuned to sound as natural as possible. We work from your melody and lyrics, dialling in the engine to match your genre, BPM, and key. We do not perform voice-to-voice transformations, and we never clone, copy, or modify copyrighted vocal performances.

\*\*What AI Vocal Synthesis Can Do For You\*\*

AI vocal programming is a genuinely versatile tool across a wide range of production scenarios:

– Create demo vocals to present ideas to bands, singers, or collaborators
 – Add harmony or support vocals that sit alongside a real vocal performance
 – Develop heavily processed vocal effects — vocoders, pitch shifters, experimental tones
 – Incorporate gang vocals or choir layers into your arrangement
 – Serve as the primary vocal performance in a finished production

\*\*What You Receive\*\*

Every delivery includes two studio-quality WAV stems for maximum flexibility in your mix:

– Raw generated vocal as a WAV file at 48 kHz / 24-bit stereo
 – Processed vocal (EQ, compression, de-esser, exciter applied) as a WAV file at 48 kHz / 24-bit stereo

Both stems are delivered as downloads, ready to drop straight into your DAW session.

\*\*What We Need From You\*\*

To get started, please provide:

– Genre, BPM, and key of your track
 – Male or female vocal preference
 – Complete lyrics
 – A MIDI file containing the topline melody, or a lead sheet with the song key
 – For harmony vocal programming: the harmonic relationships required (e.g. a 3rd up or down from the main vocal)
 – For independent additional melody lines: the melody as MIDI or sheet music

\*\*Who This Is For\*\*

This service suits producers, songwriters, composers, and artists at any stage — from early-stage demos that need a vocal reference to finished productions seeking polished, processed vocal layers. If you have the melody and the lyrics, Zinn Digital handles the rest.

\*\*Why Zinn Digital\*\*

Zinn Digital is a London-based digital production studio with a clear, professional workflow and a focus on delivering natural-sounding results from synthesised sources. Every vocal line is programmed with care — not simply generated and sent — ensuring the output serves your music rather than fighting it.
