Web Resources
On this page you will find a general set of links that you can use as the starting point of your own investigations on the Internet for material related to the course. If you have suggestions for other pages you think would be interesting for students on the course, mail them to Mark Huckvale.
General Sources of Information
Introduction to Acoustics Booklet. A brief introduction to acoustical concepts, written by Mark Huckvale at UCL. Clicking on the link will download a large PDF file.
Internet Institute for Speech and Hearing. A well-organised source of information about web resources in Phonetics, Speech and Hearing. Has information about books, journals, tutorials, demos and tools relevant to the Acoustics Course.
Speech Analysis Tools

WASP - Waveforms Annotations Spectrograms and Pitch
WASP is a program for the recording, display and analysis of speech on personal computers. With WASP you can record and replay speech signals, save them and reload them from disk, edit annotations, and display spectrograms and a fundamental frequency track.

ESYNTH - Harmonic analysis/synthesis teaching tool
ESynth is a program designed to explain the harmonic analysis and synthesis of signals. With ESynth you can create signals by adding together individual sinusoidal waveforms (sinewaves) and study the resulting waveform and spectrum. You can also perform an analysis of an input waveform, to see how a given sound can be represented in terms of a sum of sinewaves.

ESYSTEM - Signals and Systems teaching tool
ESYSTEM is a program for experimenting with signals and systems. With ESYSTEM you can see the effect of simple systems on a range of simple signals. You can generate simple signals such as sinewaves, pulses, pulse trains, sawtooth and noise; you can pass them though systems such as an amplifier, a resonator, a low-pass, high-pass or band-pass filter, or a vocal tract model. You can observe the effect on the input and output waveforms and the input and output spectra. Now includes extensive tutorial!

SFS - Speech Filing System Tools for Speech Research
The Speech Filing System (SFS) is a software suite running on Windows and Unix systems for the storage and analysis of speech data. It provides a comprehensive environment for speech signal processing, synthesis and recognition.
