• InfoZip UNZIP for Windows (113K, EXE)
• InfoZip ZIP for Windows (104K, EXE)
• WAV File Format A description of this popular, uncompressed file format which is used extensively in laboratories in this course.
• Another description of the wave file format (from Stanford University). added Thu Sep 24 2009
• WAVE-GEN A BASIC program which generates a sine wave. Similar to lab #1, this program illustrates the basic structures required in the header of the file.
• TEST.WAV The output file from the WAVEGEN program. Inspect the header using DEBUG to see how bytes are organized. Note that although the data size is specified as 0x2D22 bytes (11554 bytes) in the header, the actual number of data bytes written to the file is 16100. This is allowable, although Media Player only plays 11554 samples.
• Harmonics An audible demonstration of harmonics and Fourier synthesis
• The Fourier Series A Java applet allowing synthesis of waves graphically
• Fourier Analysis and Synthesis A Java applet allowing synthesis of waves, graphically, and playback on a PC
• Audacity An audio editor for Windows (and other platforms) added Thu Sep 16 2010
