Musical signal processing with labview  (Page 20/6)

	This module refers to LabVIEW, a software development environment that features a graphical programming language. Please see the LabVIEW QuickStart Guide module for tutorials and documentation that will help you:
• Apply LabVIEW to Audio Signal Processing
• Get started with LabVIEW
• Obtain a fully-functional evaluation edition of LabVIEW

Introduction

Music synthesis and audio signal processing apply digital signal processing (DSP) concepts to create and control sound and to apply interesting special effects to musical signals.As you implement and experiment with synthesis and filtering algorithms, you develop a deeper understanding of the inter-relationships between a physical sound, its visualrepresentations such as time-domain waveform and spectrogram, and its mathematical model.

Richard Hamming once said "the purpose of computing is insight, not numbers," and you gain manifold insights when you interact with a signal processing system that you created yourself.The LabVIEW Development Environment by National Instruments Corporation is an excellent tool you can use to convert mathematical algorithms into real time interactivemusic synthesizers and audio signal processors. The unique graphical dataflow programming environment of LabVIEW allows DSP elements such as signal generators, filters, and other mathematical operatorsto be placed and interconnected as a block diagram. Placing user controls and indicators on the block diagram automatically generates an interactive graphical user interface (GUI) front-panel display,dramatically reducing the development effort needed to make an interactive application.

Musical Signal Processing with LabVIEW , a multimedia educational resource for students and faculty, augments traditional DSP courses and supports dedicated courses in music synthesis and audio signal processing.Each of the learning modules blends video, text, sound clips, and LabVIEW virtual instruments (VIs) into explanation of theory and concepts, demonstration of LabVIEW implementation techniques to transform theory into working systems,and hands-on guided project activities. Screencasts -- videos captured directly from the computer screen with audio narration and a hallmark of this resource -- use a mixture of hand-drawn text,animations, and video of the LabVIEW tool in operation to provide a visually rich learning environment.
