<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'>Hello<br><br>Well I am using the very same code...! The display is different according to the Gtreamer version used... I have a doubt regarding the use of "gst_element_link_filtered" : I have the same result whatever I use it or not to link my elements. I will check that technically in another post, then see if the problem continues or not.<br><br>Thanks<br><br><div><br><pre>> <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>This looks like a regression in spectrum. It wasn't really rewritten,<br>but it was refactored a bit and IIRC the API changed slightly too.<br> <br>Take a look at the example in gst-plugins-good/tests/examples/spectrum<br>to see if you're still using it correctly. If you do, please open a bug<br>report at <a href="http://bugzilla.gnome.org" target="_blank">http://bugzilla.gnome.org</a> with a testcase to reproduce the<br>different behaviours.
