I have an Asterisk SIP server. When I playback an audio file (.ulaw file, compressed using ulaw) I hear a noticeable click (or sound artifact) before the playback begins. This "click" is not in the actual audio file and happens at the start of every Playback command in the ael script. Should I be using a different format, is this a codec issue, how do I resolve this issue?
我的一些档案:
不用看档案,就很难说,但如果档案的第一份样本以零以外的某种价值开始,你可能会被点击(因为一个样本中的产出从0到N——一种广泛的噪音脉冲)。 如果你们不知道从“清理”开始的样本,那么在数量上收集这种数据或为零敲响和开始收集未经压缩的数据是明智的。
