Description: 用LPC213X系列的PWM来产生语音。语音数据来源于PC机转换后得到的。最大可以是16位的。
由于是PWM所以输出端口需要低通滤波才能够得到比较干净的声音。
可以经过修改使用LPC2132以上的ARM的D/A来产生。
This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM. -LPC213X series used to generate the PWM voice. Voice data from the PC after the conversion. It is the largest of 16. Because there is PWM output ports need low-pass filter can be relatively clean voice. It has been modified over the use LPC2132 ARM D/A to produce. This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

Description: 音频设计一直是大多数电子工程师热衷的课题，在音频设计中人们对完美的追求远远超过对成本的考虑。然而，最简单的电路有时可提供最佳性价比方案。虽然市场上众多新的低功率扬声器彰显出向D类音频性能发展的趋势，但就低成本、低失真和低噪声而言，AB类音频性能仍然最有竞争力。 -Audio Design has been the most enthusiastic about the subject of electronic engineers in the audio design in the pursuit of perfection far beyond cost considerations. However, the most simple circuit can sometimes provide the best cost-effective program. Although the market on a wide range of new low-power speaker underlines Class D audio performance to the development trend, but on the low-cost, low distortion and low noise is concerned, AB audio performance is still the most competitive.
