V80
- 音频信号发生,将频率输出转化成声音输出
readaudioshow
- 从麦可风读取声音,并且实时生成波形,可以按波形和频率两种方式查看。
specdisp
- 自己写的利用FFT变换实现的声音频谱分析函数,支持多声道wav,可以对FFT变换点数、时间分辨率、频率分辨率、显示方式进行定制-Wrote it myself using FFT transform the voice spectrum analysis function, support multi-channel wav, can transform FFT points, time resolution, frequency resolution, and display customiz
multisamplerate
- 改变原始wav音频信号的抽样频率,并且显示处理前后声音信号的频谱.有助于帮助大家理解奈圭斯特抽样定理。-Change the original wav audio signal sampling frequency, and shows the spectrum of sound signal before and after treatment. Helps to help you understand the Nyquist sampling theorem.
Recording-delphi
- delphi开发的一套声音录制系统,包括声音频率、音量、音色的设置-delphi development of the a set of sound recording system, including frequency of the sound, the volume, in tonal settings

Electronic-Stethoscope
- 目前大夫主要以听诊器倾听病人的气管、肺部区域的声音,对病人的疾 病进行判断;请设计一个听诊的软件,要求如下: 1) 可记录病人的姓名、年龄、性别、病史、不同疾病部位等状况; 2) 对病人的气管、肺部等区域的声音进行采集、分析、存储(前端听诊 部分不用考虑,只考虑数据采集部分)。 3) 可分析不同声音分量的大小,给出频谱图,以及主要频率的幅度,便 于大夫分析和验证; 4) 由于采集到的信号经常存在某些干扰信号,比如心脏的震动,请设计 低通、带通、带阻滤波器对信号处理
AAC_Enc_Dec000
