音频分析仪详细解析 音频分析仪详细解析   1、音频信号及音频分析  音频是多媒体中的1种重要媒体。我们能够听见的音频信号的频率范围大约是20Hz⑵OkHz,其中语音大约散布在300Hz⑷kHz以内,而音乐和其他自然声响是全范围散布的。声音经过摹拟装备记录或再生,成为摹拟音频,再经数字化成为数字音频。这里所说的音频分析就是以数字音频信号为分析对象,以数字信号处理为分析手段,提取信号在时域、频域内1系列特性的进程。  各种特定频率范围的音频分析有各自不同的利用领域。例如,对300⑷kHz之间的语音信号的分析主要利用于语音辨认,其用处是肯定语音内容或判断说话者的身份;而对20⑵0kHz之间的全范围的语音信号分析则可以用来衡量各类音频装备的性能。所谓音频装备就是将实际的声音拾取到将声音播放出来的全部进程中需要用到的各类电子装备,例如麦克风、功率放大器、扬声
