Abstract: | Despite the continuing decrease in computer prices, psychoacoustic research is still expensive because of the high cost of sound-generation equipment and software. A single-chip sound generator was evaluated as an inexpensive tone/noise generator, amplitude attenuator, envelope modulator, and sound mixer. Although the chip has some limitations, it offers important advantages for pilot research and laboratory demonstrations. |
