Perfect and bit-perfect PCM encoded sine wave audio test tones
In this project, a perfect PCM sine wave is one that contains a single frequency at 0 dBTP and no error harmonics at all. A bit-perfect PCM sine wave has error harmonics due to encoding quantization, but they are at the minimum level possible for the chosen encoding.
The generated wave files hold a sequence of one or more complete copies of a repeating pattern. A file containing a single pattern can be played in a loop to extend the play time. Because most audio players don't loop...
Basic tone generator for creating test wav files. A utility type program consisting of one executable. GUI (FLTK) inteface. Optional speech synthesis in wav file for reference on CD. Compiles and runs on win and Linux platforms.
Epulse is a signal generator that can produce pulses, sine, triangular and rectangular waves with an unlimited level of modulations. It can be used in electronics to create test signals, or to make simple audio effects.
