What are we going to do?. Observe effects of fundamental processes. Estimate their relative contribution. Humming transcription. Our front-end for music search. Goal: Convert humming into an MIDI note sequence. Steps involved in humming transcription. Track pitch over the humming input. Identify notes via silence. Understanding:. Gene expression is regulated by proteins that bind to specific base sequences in DNA . The environment of a cell and of an organism has an impact on gene expression.
