Downgrade all files to 16kHz frequency ( But format issue is still there).

mp3 and there are high chances that network can be biased towards format or audio encoding. Now after this extracting various features from each frames including MFCCs, Zero-crossing rate (ZCR), Formants (the first 4) etc and at last feeding all these features to simple dense layer neural network or CNN (spectrogram format).īut the problem is both classes' audio files are in a different format class A audio samples are in. Audio segments were then divided in non-overlapping Hamming-windowed frames of 25ms.

Segmented in audio segments, by removing the silences in the signal.

Downsampled to 16kHz, the level of the signal was normalized.

What i am doing before feeding it to neural network : The yellow is not connected to anything (it looks like it's close to the green wires in the picture, but it's far away in the z axis).įileExtension_Invalid : m1a mpa mpa1 mp1 m2a mpa2 mp2 mp3įormat settings : Joint stereo / MS Stereo The blue and yellow wires come from the same white wire (you can just see them meeting in the picture). Everything seems to be working, just no chime!Įverything I've found says that terminal 0 on this chime is used for both buttons (front being 0 and 1, back being 0 and 2), but absolutely nothing is connected to terminal 0 in my chime yet one works. The same happens when I push the non-working button - which isn't strange as it's completing the circuit. If I push the working button and hold the button in, the transformer audibly works (faint buzzing). If I turn off the fuse, the working button no longer does anything, and the previously mentioned voltage drops to 0. I tried connecting a new button and the light in it turned on, but pushing the button still does nothing.īoth buttons are connected to the same electrical circuit and transformer. I have checked the voltage between the two wires for the button that doesn't work - 14.5V. it's not connected as the 'front' doorbell, which as I understand should ring the doorbell repeatedly thanks to the mercury switch). The doorbell that works only rings the chime once (i.e.

The doorbell is the same as mentioned in this old question, including the mercury switch: Purpose of mercury switch in old doorbellīut the wiring in this chime is completely different to that post and everything else I've found online. I'm not so sure the broken one ever worked. According to my wife, both doorbells worked when we moved in but one stopped working within days. I recently bought a house that has an existing Friedland No.
