<div dir="ltr">Hello All!<br><br>I have very important question (sorry for my bad English):<br><br>How can I get sound data (in speex format) which have amplitude larger than specified value?<br>I.e. I need getting speech which volume is larger than specified value.<br>
For 16-bit linear PCM-encoded data this is very simple. Because each sample contains 16 bit sound data.<br>And I compare this 16 bit value with specified value for each sample. For example, I assume that sample would part of voice,<br>
if their sample size value > 10000 or < -10000 (maximum value of sample size = 32767 (2x15-1) and minimum value = -32768 (-2x15)).<br>But how I doing similar operation with data in speex format rather than in PCM? Probably, is there some formula for this operation?<br>
My data encoded with jspeex (CBR, 8KHz (narrowband mode), mono, little endian, quality = 7).<br><br>Thanks In Advance.<br><br><br><br></div>
