I need a PHP developer to help me to build a small script to modify a firmware updating some bytes based on an uploaded file and send it back as a file again.

Actually the script is very simple. I'm a PHP programmer myself, but I'm stuck with this problem.

The firmware is for a synthesiser module that works with several wavetables that are represented with 512 two-byte (16-bit) signed (2’s-complement) samples.

The script should read the .jic firmware file (binary), go to the correct address where the wavetables are and modify them using an user uploaded .wav (the .wav is a wavetables too). And then download the modified firmware with the browser.

The firmware contains all operation code for the synthesizer + wavetables. Wavetables are a digital respresentation of a sound wave. The firmware contains several wavetables and I would be able to modify them uploading a wav file.

If you read the page 45-46 of the synthesizer, you can find the manual procedure for modifying the firmware.
