Sound analysis and representation (pc)
 Some programs can represent the inside of a sound, meaning that they analyse it from an acoustic angle [spectral analysis; sonogram; visual representation]. Volume envelope, basic frequency and partials are often analysed. An image on the screen represents the result of this analysis. 


csounds.jpg CSound
08 Jan 2004 - CSound is a successor to the legendary Music V. Like the latter, it requires some patience to learn the various commands. In fact, to produce a sound, you have to start by programming two pure text files in lines of code.
Skill level: Advanced 
sonogram.jpg Sonogram
15 Oct 2003 - 
This software enables you to represent a sound file in the shape of a sonogram (with frequency represented on the vertical axis and time on the horizontal, and intensity by colour or shades of grey). 
spectrum.jpg Spectrum Analyser
15 Oct 2003 - This spectrum analyser works with the audio input of the sound card or from a wave file.To select an input: “File” menu, “Input”.To start or stop the spectrum analysis: “Run/Stop”.
Skill level: Medium 
audiometer.jpg AudioMeter
15 Oct 2003 - Program allows user to measure audio signal present on audio input of sound card.
Learning level: Medium 
Sound-Frequency-Analyser.gif Sound Frequency Analyser
15 Oct 2003 - This software does a live analysis of the microphone input of the computer’s sound card in the form of a sonogram. This is a representation of the sound on two axes (horizontal = time, vertical = frequencies).
Skill level: Basic 
Oscilloscope.jpg Oscilloscope
10 Oct 2003 - Simulates an oscilloscope : represents the amplitude envelope of a sound signal. The signal represented can be stereophonic.
Learning level: medium

16 Sep 2003 - Tutorial Sequencer: recording, audio editing, audio processing, Sequence, Mixing
Skill level : medium 
winoscillio.jpg Winoscillo
15 Sep 2003 - 
WinOscillo enables you to visualise the sound amplitude and spectrum according to time and spectrum analysis with FFT 
ana-lfreq.jpg AnalFreq
15 Sep 2003 - Detailed user guide: Analysis and representation - This software enables you to make a representation of instant spectrum and medium spectrum.
Skill level: basic 
asia.jpg Asia
15 Sep 2003 - Asia 2.1 is the professional's choice for editing and producing .wav files. It's ideal for games, video films, multimedia applications and web pages.
