The demo gap

Your production is ready. The topline is not.

A strong instrumental can still be difficult to present without a vocal melody. Hiring a topliner and demo vocalist for every early idea is expensive, slow, and difficult to predict.

  • 01

    Finding the right vocalist takes time

    Availability, style, and budget rarely line up when the idea is still fresh.

  • 02

    Every unfinished direction can cost money

    Paying for a topline you may not keep makes experimenting expensive.

  • 03

    Revisions add days to the process

    Each round of notes means another wait before you can hear the change.

  • 04

    A silent instrumental is harder to pitch

    Collaborators have to imagine the vocal instead of hearing it.

PeakTone turns the missing vocal idea into something you can hear, evaluate, and improve.

Examples

From instrumental to complete song concept.

Hear how one production develops from a backing track into a usable vocal reference. All examples are AI-generated demo vocals made for reference, not final releases. Audio for the beta examples is being finalised, so playback is disabled until the files are published.

How it works

A faster path from instrumental to vocal direction.

  1. STEP 1

    Upload your instrumental

    Start with the production you already made. PeakTone analyses the tempo, key, energy, and song structure.

  2. STEP 2

    Choose the section and direction

    Confirm the verse, chorus, pre-chorus, or bridge. Set the genre, mood, complexity, and vocal direction.

  3. STEP 3

    Generate or upload a topline

    Explore melody ideas created for the selected section, or upload your own MIDI melody.

  4. STEP 4

    Add lyrics and render the demo

    PeakTone aligns lyrics with the melody and generates a sung vocal reference over your instrumental.

  5. STEP 5

    Refine, present, and collaborate

    Use the result to develop the song, pitch the idea, or give the final vocalist a much clearer creative brief.

Why PeakTone

Test the topline before you pay for the final vocal.

Traditional demo workflow

  • Find a topliner and vocalist
  • Explain an unfinished idea
  • Wait for the first version
  • Pay for experiments that may not work
  • Organize revision rounds
  • Send an uncertain brief to the final singer

With PeakTone

  • Start immediately with your instrumental
  • Hear multiple vocal directions
  • Evaluate ideas before committing
  • Edit the structure, melody, and lyrics
  • Upload your own MIDI when needed
  • Send a concrete vocal reference to collaborators

PeakTone is not a replacement for the final vocalist. It improves the creative process that happens before one is hired.

Value

More than an AI vocal generator.

  • Built around your track

    PeakTone works from your instrumental instead of replacing it with a newly generated song.

  • Section-aware ideas

    Generate a chorus that behaves like a chorus, a verse that leaves space, and a bridge that creates contrast.

  • Creative control

    Correct the arrangement, choose between ideas, change the lyrics, or upload your own MIDI.

  • A demo people can understand

    Present the song as a complete idea instead of asking collaborators to imagine the missing vocal.

Use cases

Built for the moment between production and final recording.

  • DEVELOP

    Develop the idea

    Test melodies and lyrics while the production is still evolving.

  • PITCH

    Pitch the song

    Give artists, labels, and collaborators a complete concept they can understand immediately.

  • BRIEF

    Brief the final vocalist

    Communicate melody, timing, phrasing, lyrics, and emotional direction with a playable reference.

Founder

Built from a producer's real workflow.

PeakTone was created by Marcus Peak, a producer with more than 20 years of music-making experience whose tracks and remixes have been played on Estonian radio. It started with a familiar problem: a finished instrumental is difficult to evaluate and present while the vocal idea exists only in your head.

“The goal is not to replace the final artist. The goal is to make the idea clear enough that everyone can hear its potential.”
