重新进行取样?

修改速度指什么? 保持采样率不变和单调不变使声音变快吗?

改变频率指升降调吗?

Analyzing a raw file format
If you are analyzing a file that does not contain an audio header (.vox or .ulw), the Raw File Format dialog opens.

VOX, ULW, and ALW files do not contain an audio header to signify the sample rate the file was recorded with or the encoding format. For these files you need to manually specify this information so the data can be properly interpreted.

The Audio File field displays the path and filename of the file that does not contain an audio header.
In the Sample Rate field, select the correct radio button (valid sample rates are 8000Hz, 11025Hz, and 22050Hz) of the sample rate the audio file was recorded.
In the Format field, select the correct radio button for the audio encoding format for file that does not contain an audio header. Valid formats are:
Intel (LSB, MSB)
Motorola (MSB, LSB)
A-Law 8Bit
mu-Law 8Bit
