<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'>Hello<br><br>My app displays harmonics of the sound in 3D, thanks to the 'spectrum' element.<br>When I use the microphone of the computer as the audio source, with Gstreamer-0.10, I have a clear view of the harmonics.<br>When I do the same with Gstreamer-1.0, the sensitivity seems much higher, and I have a huge "background" noise contamining the spectrum data, especially in the lower frequencies (but also in the rest of the spectrogram), wich makes the ratio sound/background noise much lower. I can lower the sensitivity of the microphone but in that case, I loose the interesting display...<br><br>When I do an analysis of an audio file (either a flac, wac, mp3... or a file recorded by the app), it works fine.<br><br>I join two pictures to show the difference, when pronouncing differents voyels; you must see higher and lower harmonics, according to wich voyel is said; on the first pic, when gst-0.10 is used, you can see a very clear drawing; on the second pic, when gst-1.0 is used, although the sensitivity of the mic is lessened, the ratio sound/background noise is much worse.<br><br>I guess the spectrum element has been rewritten. What is possible to change? Is it possible to get more information on how this plugins works?<br><br>Victor<br><br>Gst-0.10<br><br><div id="inlineImage2" style="display: inline-block"><script type="jsv#707_"></script> <span contenteditable="true"> </span> <div initwidth="637" initheight="398" class="inlineImage" style="display: inline-block" unselectable="on" contenteditable="false"><img src="cid:inlineImage2" height="398" width="637"></div> <span contenteditable="true"> </span><script type="jsv/707_"></script></div><br><br><br>Gst-1.0<br><br><div id="inlineImage3" style="display: inline-block"><script type="jsv#708_"></script> <span contenteditable="true"> </span> <div initwidth="605" initheight="378" class="inlineImage" style="display: inline-block" unselectable="on" contenteditable="false"><img src="cid:inlineImage3" height="378" width="605"></div> <span contenteditable="true"> </span><script type="jsv/708_"></script></div><br> </div></body> </html>
