Music Signal ecLab Flow Resynthesizer Project

I’m building a Flow Resynthesizer devoted to audio processing, with the sole purpose of transforming musical signals in creative, non-destructive ways. The core idea is to take an incoming music track, analyze its spectral and temporal features, and then re-synthesize it so the output feels like a fresh performance while still carrying some elements of its original recorded instrument different properties are expected as this is just a starting point.

Here’s what I need from you:

• A clean, well-documented codebase (Python, Java) that ingests stereo music files, performs detailed analysis (FFT, phase vocoder or another suitable method), and produces a re-synthesized signal using a refactored version of the Flow Synthesizer.

• Parameter controls for users to experiment with texture, pitch, and time characteristics, ideally exposed through a simple UI modifications..

• Consideration for latency, CPU efficiency, and artefact-free output, so the tool remains usable both in studio sessions and live performance settings.

Once I can run the processor on a test track and hear a clean, musically convincing transformation with adjustable parameters, the job is done. If you have existing DSP libraries or proprietary tricks that accelerate development, feel free to integrate them—just keep everything modular and maintainable.

Project is Either pass or fail if you can't complete project you agree to allow full refund by accepting this project.

Seeking : Priority 1 Python / Java DSP Programmer | Priority 2 UI Programmer

Price for Project: $700 on completion only (No Success no pay)

How the project will work:

Note: This project will require that you trust that fact that if you complete the project that I am going to pay you in full I have never not payed anyone who completed a project successfully know that(Serious).

Me setting up th milestones this way is a precaution as I have had plently who say they will start then leave and make me wait a a whole week to time out and not release my milestones not happening.

Payment setup:
I start with $300 milestone to prove task is active and that I'm not joking about this project

when I check and verify that the project works as intended I create 2nd milestone $400 immediately pay both milestones $300 + $400 = $700

1 Milestone active now pay 2 milestone later

Also NDA sign with be required I take ownership of project as well as it is my idea and I'm lead on the Project I'm hiring you to execute this gameplan and we work together on this.

Deadline 2 weeks if you don't make the 2week deadline I can choose to continue or end the project ( If you are doing good work don't worry I'll continue but after 2 weeks you are behind the clock and I need this ready).

Freelancer is available on mobile you are expected to respond to my texts within 48hours need more time simply say so I am great to work with.

File format: .WAV Separated single instrument audio stem file

UI: Desktop only Eclab Flow already as a UI to work with.
